Mode for Carrying Out the Invention

[0024] Hereinafter, the present invention will be described through embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are necessarily essential as means for solving the problems. For the sake of clarity of explanation, the following description and drawings have been appropriately omitted and simplified. In each drawing, the same reference numerals are assigned to the same elements, and duplicate explanations are omitted as necessary.

[0025] Embodiment 1. In this embodiment, as an example of training equipment, a pedaling exercise device will be described. The training equipment is a pedaling exercise device (hereinafter also simply referred to as an exercise device) for a user to perform a pedaling exercise. The processing system and the processing method according to this embodiment perform processing for recommending recommended settings for the setting items of the device in training on the pedaling exercise device. For example, the processing system outputs recommended settings to a trainer who performs a pedaling exercise or an assistant who assists in the training. By doing so, the trainer can perform training with an appropriate load.

[0026] The exercise machine 100 will be described with reference to FIGS. 1 and 2. FIGS. 1 and 2 are views of the exercise machine 100 seen from the side. In the following description, for the sake of clarity, the description will be made using the XYZ three-dimensional orthogonal coordinate system. Specifically, the +X direction is the forward direction, the -X direction is the rear direction, the +Y direction is the upward direction, the -Y direction is the downward direction, the +Z direction is the left direction, and the -Z direction is the right direction. The front-rear direction, the left-right direction, and the up-down direction are directions based on the direction of the user U.

[0027] The exercise machine 100 is capable of adjusting the range of motion of the ankle joint. In the following description, the rotational direction of the ankle joint around the Z-axis is defined as the plantar dorsiflexion direction, and the angle thereof is defined as the plantar dorsiflexion angle. More specifically, the direction in which the toes of the foot FT point downward is defined as the plantar flexion direction, and the direction in which the toes point upward is defined as the dorsiflexion direction.

[0028] As shown in FIG. 1, the exercise machine 100 includes a main body 20, a link 30, a crank 40, and an inclined table 50. A chair 10 is provided behind the exercise machine 100. The user U performs a pedaling motion while sitting on the chair 10. Therefore, the chair 10 serves as a seating portion on which the user U sits. Note that the chair 10 may be provided integrally with the exercise machine 100 or separately. For example, the chair 10 may be a chair in a facility or a home where the user U is located. That is, the user U or an assistant may install the chair 10 behind the exercise machine 100.

[0029] The chair 10 includes a seat portion 11 that serves as a seating portion and a backrest portion 12. With the user U sitting on the seat portion 11, the backrest portion 12 supports the user U's back. That is, the user U can perform a pedaling motion while leaning on the backrest portion 12. Further, the chair 10 is interchangeable or adjustable according to the user U. For example, for a user U who performs a higher-load training, a chair 10 without a backrest portion 12 can be used. Alternatively, the backrest portion 12 may have a reclining mechanism. Then, the angle of the backrest portion 12 may be adjusted by the reclining mechanism.

[0030] In the exercise device 100, the components attached to the main body 20 are symmetric left and right. In FIG. 2, to distinguish the left and right components, an L is attached to the component on the left side of the main body 20, and an R is attached to the component on the right side. For example, in FIG. 2, the left inclined table 50 is shown as the inclined table 50L, and the right inclined table 50 is shown as the inclined table 50R. Similarly, the left link 30 and pedal 31 are the link 30L and pedal 31L, and the right link 30 and pedal 31 are the link 30R and pedal 31R. Similarly, the left foot FT is the left foot FTL, and the right foot FT is the right foot FTR. In the following description, when not distinguishing between the left and right components, L and R are omitted.

[0031] The main body 20 rotatably holds the crank 40. For example, a rotating shaft 21 is provided on the main body 20. The crank 40 is connected to the rotating shaft 21. The crank 40 rotates around the rotating shaft 21. The main body 20 may have a load resistor that applies a load to the rotational movement of the crank 40. Note that the main body 20 may have a gear or the like for making the load variable.

[0032] The main body 20 is disposed on the installation table 15. The installation table 15 is disposed on the floor surface. For example, the front portion of the main body 20 is disposed on the installation table 15, and the rear portion is disposed on the floor surface. By changing the height, position, etc. of the installation table 15, the installation angle of the main body 20 can be changed. For example, by removing the installation table 15, the main body 20 is disposed horizontally. Also, by raising the installation table 15, the installation angle of the main body 20 becomes steeper. Thus, by changing the height of the installation table 15 or removing the installation table 15, the posture of the user U during training changes. Therefore, the range of motion of the joints due to the training of the user U can be adjusted.

[0033] Also, according to the user U, the front-rear direction distance between the main body 20 and the chair 10 may be changed. For example, the user U can place the chair 10 closer to the main body 20. Thereby, the user U performs a pedaling motion with the knee joint and the like relatively bent. Alternatively, the user U can place the chair 10 farther from the main body 20. Thereby, the user U performs training with the knee joint and the like relatively extended. By changing the distance between the main body 20 and the chair 10 in the X direction in this way, the posture of the user U during training changes. Therefore, the range of motion of the joints due to the training of the user U can be adjusted.

[0034] The link 30 has a pedal 31 and a sliding wheel 35. A crank 40 is connected to the front end of the link 30, and a sliding wheel 35 is connected to the rear end. The crank 40 and the link 30 are rotatably connected. For example, the link 30 is attached to the crank 40 via a bearing or the like. The pedal 31 is attached in the middle of the link 30. The pedal 31 serves as a step (footrest) on which the user U places the foot FT. The seated user U places the foot FT on the pedal 31.

[0035] The sliding wheel 35 is attached to the link 30 via a rotating shaft (axle). That is, the link 30 rotatably holds the sliding wheel 35. The sliding wheel 35 serves as a sliding member that slides on the inclined surface of the inclined table 50.

[0036] The user U places the foot FT on the pedal 31 and performs a pedaling motion. That is, the user U moves the knee joint and the hip joint so as to step on the foot FT. Thereby, the crank 40 rotates around the rotation axis 21. Further, according to the rotation of the crank 40, the angle between the link 30 and the crank 40 changes. That is, the relative angle of the link 30 with respect to the crank 40 changes according to the rotation angle of the crank 40 (also referred to as the crank angle). Also, the sliding wheel 35 moves in the front-rear direction while being in contact with the inclined surface. Thereby, according to the pedaling motion, the crank 40 and the link 30 rotate so that the pedal 31 draws an elliptical orbit.

[0037] Note that the pedal 31, the sliding wheel 35, the link 30, the crank 40, and the inclined table 50 are respectively provided for the left and right feet FT of the user U. That is, the pedal 31, the sliding wheel 35, the link 30, the crank 40, and the inclined table 50 are provided on the left and right sides of the main body 20 respectively. The pedal 31R, the sliding wheel 35R, the link 30R, the inclined table 50R, etc. provided on the right side of the main body 20 correspond to the right foot FTR of the user U. The pedal 31L, the link 30L, and the inclined table 50L provided on the left side of the main body 20 correspond to the left foot FTL of the user U.

[0038] The crank 40 is attached to the rotation shaft 21 of the main body 20 so as to be out of phase with respect to the left and right feet FT. That is, the rotation angles of the crank 40 for the left foot and the crank 40 for the right foot are shifted by 180°. The user U alternately extends and contracts the left and right feet to perform a foot rowing motion.

[0039] The sliding wheel 35 is attached to the lower end of the link 30. The sliding wheel 35 has a wheel that slides on the inclined surface of the inclined table 50. The inclined table 50 has an inclined surface that becomes higher toward the rear. The sliding wheel 35 reciprocates in the X direction (front-rear direction) according to the rotational movement of the link 30. As shown in FIG. 1, while the user U extends the right foot and performs a foot rowing motion in the direction of bending the left foot, the right sliding wheel 35 moves forward and the left sliding wheel 35 moves backward. As shown in FIG. 2, while the user U extends the left foot and performs a foot rowing motion in the direction of bending the right foot, the left sliding wheel 35 moves forward and the right sliding wheel 35 moves backward.

[0040] The height of the sliding wheel 35 changes along the inclined surface of the inclined table 50. The inclined table 50 has a higher inclined surface height toward the rear. That is, the inclined table 50 is an uphill for the sliding wheel 35 moving backward. Therefore, while the sliding wheel 35 is moving backward, the sliding wheel 35 gradually becomes higher. On the contrary, while the sliding wheel 35 is moving forward, the sliding wheel 35 gradually becomes lower. The angle of the link 30 is defined according to the height of the sliding wheel 35.

[0041] Here, according to the height of the sliding wheel 35, the angle of the pedal 31 provided on the link 30 is restricted. That is, when the sliding wheel 35 becomes higher, the pedal 31 rotates in the plantar flexion direction. When the sliding wheel 35 becomes lower, the pedal 31 rotates in the dorsiflexion direction. Therefore, according to the inclination angle of the inclined table 50, the movable range of the plantar-dorsiflexion angle of the ankle joint can be adjusted. According to the rotation angle of the crank 40, the movable range of the plantar-dorsiflexion angle of the ankle joint can be adjusted.

[0042] User U performs a pedaling motion on the exercise device 100 for training. That is, by the user U performing a pedaling motion, a load can be applied to the muscles of the lower limbs and the trunk. Muscles that can be trained with the exercise device 100 include the erector spinae muscles (PS), rectus abdominis muscles (RA), external oblique abdominal muscles (OEA), hip flexor muscle groups (HF), gluteus maximus muscles (GM), rectus femoris muscles (RF), tibialis anterior muscles (TA), soleus muscles (SOL), gastrocnemius muscles (MG), vastus medialis muscles (VM), MH (hamstrings), etc. Also, one or more muscle parts that the user U or the assistant wants to train can be specified.

[0043] (Setting items) Here, with the exercise device 100, parameter settings regarding various setting items are possible. By the user U or the like changing the parameters of each setting item, training can be effectively performed. By the user U changing the parameters for each setting item of the exercise device 100, the muscle parts that can be trained by the pedaling motion and the load amount thereof can be adjusted. Thereby, effective training becomes possible. Note that the parameter setting for each setting item is not limited to the user U himself / herself who performs the training, and may be performed by an assistant who assists with the training. The assistant may be a physical therapist or an occupational therapist, etc.

[0044] Examples of the setting items in the exercise machine 100 include, for example, the rotational speed of the crank 40, the load on the crank 40, and the rotational direction of the crank 40. For example, by increasing the rotational speed or increasing the load on the crank 40, a high load can be applied to the muscles. Furthermore, by changing the rotational direction of the crank 40, the muscle part to which the load is applied can be changed.

[0045] In addition, as other setting items, there are settings for changing the geometric arrangement of the exercise machine 100. Such setting items include the front - rear distance between the chair 10 and the main body 20, the installation angle (tilt angle) of the main body 20, the tilt angle of the pedal 31, the tilt angle of the tilt table 50, and the front - rear position of the tilt table 50. According to the front - rear position of the tilt table 50 and the tilt angle of the tilt table 50, the operating angle range of the ankle joint can be changed. Also, by changing the front - rear distance between the main body 20 and the chair 10, the tilt angle of the main body 20, etc., the operating angle ranges of the knee joint and hip joint change. That is, by changing the parameters of the setting items, the posture during training, etc. can be changed. By changing the parameters of such setting items, the muscle part to be trained and its load can be adjusted.

[0046] Also, as another setting item, there is the presence or absence of the backrest part 12. For example, when preparing a chair 10 with a detachable backrest part 12 and performing high - load training, the backrest part 12 can be removed. Alternatively, chairs 10 with a backrest part 12 and chairs without a backrest part can be prepared respectively, and the chair 10 can be exchanged according to the training. In this way, a plurality of chairs 10 can be prepared and the chair 10 can be exchanged according to the training.

[0047] In addition, as other setting items, those that do not involve adjustment, modification, or replacement in the exercise equipment 100 are applicable. For example, the posture and movement of the user U may be used as setting items. Specific setting items include the presence or absence of folding the arms and the presence or absence of arm-swinging movements. For example, during the rowing exercise, the user U can change the setting item by selecting the presence or absence of the arm-swinging movement. Alternatively, the parameters can be changed by the user U selecting whether to fold the arms or not. Depending on the posture and movement of the user U in this way, the muscle parts to be trained can be changed.

[0048] In the exercise equipment 100, various setting items can be set. In other words, by appropriately setting the parameters of the setting items, an appropriate load can be applied to each muscle part. That is, a desired load can be applied to each muscle part. For example, a high load can be applied to the muscle parts that the user U and others want to train intensively. Alternatively, for areas with injuries, the load can be reduced or the movement angle range can be restricted.

[0049] As described above, as setting items, there are items that can be set as numerical parameters such as speed, angle, and relative position. Alternatively, as setting items, there are items that can be set step by step such as high level, medium level, and low level. In addition, among the setting items, there are those that can be set by the presence or absence of equipment or operations. As setting items, there are items that can be changed by arranging or replacing equipment. Also, as setting items, there are those that can be changed by the training posture or training movement of the user. For example, in some setting items, the presence or absence of an operation or equipment can be used as a parameter.

[0050] A processing system capable of outputting the recommended settings of the above setting items will be described. FIG. 3 is a block diagram showing the configuration of the processing system 200. The processing system 200 includes an input unit 201, a user data acquisition unit 202, a muscle part data acquisition unit 203, a recommended setting calculation unit 211, a simulator 212, an output unit 230, and a determination unit 240.

[0051] The processing system 200 may be composed of, for example, a personal computer having a processor, a memory, etc. Therefore, the processing system 200 stores a processing program in advance. And by the processor of the processing system 200 executing the program, it becomes possible to execute the processing described later.

[0052] The input unit 201 includes input devices such as a touch panel, a keyboard, and a mouse. By the user U or an assistant (hereinafter, collectively referred to as the user U, etc.) operating the input unit 201, various kinds of information can be input. Alternatively, the input unit 201 may have a microphone or the like for performing voice input.

[0053] The user data acquisition unit 202 acquires user data regarding the user U who performs training. The user data includes the physical information of the user U. For example, it includes the height, weight, length of the lower limbs, length of the upper limbs, length of the trunk, etc. of the user U. Furthermore, the user data may include other characteristics such as age and gender, not limited to physical characteristics.

[0054] For example, the user U, etc. operate the input unit 201 to input numerical values such as height. Thereby, the user data acquisition unit 202 acquires the user data of the user U. Alternatively, the user data acquisition unit 202 may read the user data from a memory or the like. For example, assume that the user ID and the user data are associated and stored in a memory or the like. The processing system 200 may store a user table in which user data such as height is associated for each user. In this case, by the user U, etc. inputting the user ID, the user data acquisition unit 202 reads the user data from the memory.

[0055] The muscle part data acquisition unit 203 acquires muscle part data indicating the muscle part that the user U wants to train. For example, the user U or the like operates the input unit 201 to input the muscle part to be trained. As the muscle parts, as described above, there are erector spinae muscles (PS), rectus abdominis muscles (RA), external oblique abdominal muscles (OEA), hip flexor muscle groups (HF), gluteus maximus muscles (GM), rectus femoris muscles (RF), tibialis anterior muscles (TA), soleus muscles (SOL), gastrocnemius muscles (MG), vastus medialis muscles (VM), MH (hamstrings), etc. Furthermore, only one of the left and right muscle parts may be input. For example, when one of the left or right legs is injured, the load can be changed between the injured leg and the other leg.

[0056] For example, the display shows a list indicating a list of muscle parts, and the user U or the like selects a muscle part from among them. Alternatively, the muscle part data acquisition unit 203 may specify the muscle part to be trained in the form of a question. Specifically, the output unit 230, which will be described later, outputs a question for specifying the muscle part that the user U wants to train. Then, by the user U or the like answering the question, the muscle part data acquisition unit 203 specifies the muscle part to be trained. When the user U or the like wants to train a plurality of muscle parts, the muscle part data acquisition unit 203 may acquire two or more muscle parts as muscle part data. Also, the muscle part data acquisition unit 203 may specify the muscle part to be trained by the user U or the like designating the muscle part that they do not want to train.

[0057] Furthermore, the muscle part data acquisition unit 203 acquires the amount of load to be applied to the muscle part to be trained. For example, the user U operates the input unit 201 to input the muscle part and its load amount. Thereby, the muscle part data can acquire muscle part data regarding the muscle part to be trained and its load amount. The load amount may be a numerical value such as a percentage (%), or may be set at a stepped level such as high or low. Of course, it may be set at three or more levels such as high, medium, and low.

[0058] The recommended setting calculation unit 211 calculates the recommended settings for the setting items based on the user data and the muscle part data. The recommended setting calculation unit 211 obtains the recommended settings by referring to past measurement results and simulation results. For example, by measuring the myoelectric potential of the user U during training, the change in the load applied to the muscle part can be obtained. That is, the parameters of each setting item are changed, and the myoelectric potential is measured in advance. The myoelectric potential corresponds to the muscle activity level or the firing degree of the muscle. By doing so, the setting items highly correlated with the muscle part can be obtained in advance. For example, a table or the like in which the muscle parts to be trained for each setting item and its parameters are associated is created in advance. The recommended setting calculation unit 211 can present appropriate recommended settings for each setting item by referring to the table or the like.

[0059] The simulator 212 calculates the muscle activity level using, for example, a computer. The simulator 212 calculates the muscle activity level using a human computer model (such as a human model like a human finite element model). That is, the simulator 212 calculates the change in the muscle activity level of each muscle due to the pedaling motion. The simulator 212 calculates the time change in the muscle activity level during one rotation time. For example, by inputting physical data such as height and lower limb joint length, the simulator 212 creates a human model having that physique and performs a simulation.

[0060] The simulator 212 can perform simulations on human models of various physiques using a human computer model such as a human finite element model. By changing the simulation conditions of the simulator 212, a plurality of simulation results can be obtained. As described above, the simulation conditions include physical data such as height and lower limb joint length. Furthermore, the simulation conditions include the parameters of the setting items of the exercise device 100.

[0061] In a human body model of a single build, the simulator 212 performs multiple simulations by changing the parameters of each setting item. By doing so, multiple simulation results for a human body model with a build similar to the user data can be obtained. For a human body model with a build similar to the user data, simulation results are calculated by changing the parameters of each setting item. For a human body model with a build similar to the user data, the change in muscle activation level when the parameters of each setting item are changed can be understood. The muscle activation level corresponds to the load applied. The simulator 212 outputs the simulation results of simulating the load applied to each muscle part.

[0062] By comparing the simulation results of the simulator 212, the differences in muscle activation level for each muscle can be compared. For example, simulations are performed by changing the rotation direction and rotation speed of the crank 40. Thereby, the differences in muscle activation level due to the rotation direction and rotation speed of the crank 40 can be evaluated for each muscle. Further, in the case where there is a swinging motion of the arm, by comparing the simulation results with and without the swinging motion of the arm, the differences in muscle activation level due to the presence or absence of the swinging motion of the arm can be evaluated for each muscle. The simulator 212 performs simulations by changing the installation angle of the main body 20, the inclination angle of the inclined table 50, etc. Thereby, the differences in muscle activation level when the geometric arrangement of the exercise equipment 100 is changed can be evaluated.

[0063] The recommended setting calculation unit 211 may calculate the recommended settings by referring to the simulation results by the simulator 212. That is, the simulation results of the personality model with a build similar to the user data are compared. Then, the recommended setting calculation unit 211 calculates the setting items with a large correlation for the muscle part to be trained. For the setting items with a high correlation, the optimal setting values for increasing the load, etc. may be calculated. For the setting items with a high correlation, the parameters for increasing or decreasing the load can be obtained for each muscle part.

[0064] Furthermore, the recommended setting calculation unit 211 can also obtain the optimal numerical values (position, angle, etc.) of the setting items. For example, the recommended setting calculation unit 211 can calculate the parameters optimal for the physique of the user U regarding the front-rear direction distance between the main body unit 20 and the chair 10. The recommended setting calculation unit 211 may calculate the optimal angles of the tilt angle of the main body unit 20 and the tilt angle of the tilt table 50. Also, the recommended setting calculation unit 211 may calculate not only a single optimal value but also a predetermined range (optimal range) as the recommended setting.

[0065] The output unit 230 outputs the recommended setting calculated by the recommended setting calculation unit 211. The output unit 230 has a display or the like and displays the recommended setting to the user U. Alternatively, the output unit 230 may have a speaker for voice-outputting the recommended setting.

[0066] Furthermore, the display of the output unit 230 may display an input screen for user data and muscle part data. For example, a touch panel display displays a keyboard and a pull-down menu for numerical input. Alternatively, the display may display questions for setting the muscle part and the load amount. Alternatively, the output unit 230 may voice-output questions for setting the muscle part and the load amount from the speaker. In this case, the user U or the like may input the muscle part to be trained and its load amount by voice input using a microphone. In this way, display output, touch panel input, voice input, and voice output can be appropriately combined.

[0067] The determination unit 240 determines whether or not the exercise device 100 is operating with the recommended setting calculated by the recommended setting calculation unit 211. When the exercise device 100 is not operating with the recommended setting, the output unit 230 notifies the user U or the like. For example, the output unit 230 may output a warning message, a warning sound, or the like. By doing so, it is possible to encourage operation with the recommended setting.

[0068] For example, the determination unit 240 may have sensors that can detect the position, angle, shape, etc. of the device. Then, based on the detection results of the sensors, the determination unit 240 determines whether the geometric arrangement of various devices matches the recommended settings. For example, the determination unit 240 may detect the presence or absence of a device such as a contact sensor. Alternatively, the determination unit 240 may detect the presence or absence of a device, the arrangement of the device, the tilt angle, etc. by analyzing the image of the exercise device 100 captured by the camera. Then, the determination unit 240 makes a determination by comparing the results detected by various sensors with the recommended settings.

[0069] The processing system 200 may be composed of a single device or may be distributed among a plurality of devices. For example, it may be a device physically different from the device having the recommended setting calculation unit 211 and the simulator 212 and the device having the input unit 201 and the output unit 230. Also, the recommended setting calculation unit 211 and the simulator 212 may be physically different devices. The recommended setting calculation unit 211 only needs to be able to refer to the simulation results of the simulator 212.

[0070] Hereinafter, the correlation between the muscle part and the setting item will be described. When the setting item is the presence or absence of the backrest part 12, the loads on PS, HF, RA, OEA, and RF increase by changing from having a backrest to not having a backrest. In particular, by changing from having a backrest to not having a backrest, the loads on RA, OEA, and RF become extremely high. Therefore, when PS, HF, RA, OEA, and RF are the muscle parts to be trained, the recommended setting calculation unit 211 calculates no backrest as the recommended setting. In other words, when PS, HF, RA, OEA, and RF are not the muscle parts to be trained, the recommended setting calculation unit 211 sets having a backrest as the recommended setting.

[0071] When the setting item is the presence or absence of the user U's arm-swinging motion, changing from no arm-swinging motion to having an arm-swinging motion increases the load on PS, RA, HF, RF, and OEA. In particular, changing from no arm-swinging motion to having an arm-swinging motion extremely increases the load on OEA. Therefore, when PS, RA, HF, RF, and OEA are the muscle parts to be trained, the recommended setting calculation unit 211 calculates having an arm-swinging motion as the recommended setting. In other words, when PS, RA, HF, RF, and OEA are not the muscle parts to be trained, the recommended setting calculation unit 211 sets no arm-swinging motion as the recommended setting.

[0072] Also, when the setting item is the presence or absence of the user U's arm-crossing, changing from no arm-crossing to having an arm-crossing increases the load on OEA and RA. Therefore, when OEA and RA are the muscle parts to be trained, the recommended setting calculation unit 211 calculates having an arm-crossing as the recommended setting. In other words, when OEA and RA are not the muscle parts to be trained, the recommended setting calculation unit 211 sets no arm-crossing as the recommended setting.

[0073] Next, the case where the setting item is the rotation direction of the crank 40 will be described. The rotation direction of the crank 40 has a forward rotation and a reverse rotation. The forward rotation of the crank 40 is the direction that is clockwise when viewing the user U and the main body 20 from the right side of the user U. The reverse rotation of the crank 40 is the direction that is counterclockwise when viewing the user U and the main body 20 from the right side of the user U.

[0074] Furthermore, the user U can choose to do a pedaling motion with both the left and right legs or with only one leg. By attaching a belt or the like to the pedal 31, it becomes possible to do a pedaling motion with only one leg. That is, when fixing one foot of the user U to the pedal 31 using a belt or a strap, the crank 40 can be rotated with only one leg. Therefore, regarding the rotation direction of the crank 40, four settings are possible: both sides forward rotation, both sides reverse rotation, one side forward rotation, and one side reverse rotation. In both sides forward rotation and both sides reverse rotation, the user U rotates the crank 40 with both the left and right legs. In one side forward rotation and one side reverse rotation, the user U rotates the crank 40 with either the left or right leg.

[0075] By changing the rotation direction of the crank 40 from bilateral forward rotation to bilateral reverse rotation, the loads on SOL, RF, HF, and VM increase. In particular, by changing the rotation direction to bilateral reverse rotation, the load on VM becomes extremely high. By changing the rotation direction to bilateral reverse rotation, the loads on TA, MG, and MH decrease. Therefore, when SOL, RF, HF, and VM are the muscle parts to be strengthened, the recommended setting calculation unit 211 sets bilateral reverse rotation as the recommended setting. When TA, MG, and MH are the muscle parts to be strengthened, the recommended setting calculation unit 211 sets bilateral forward rotation as the recommended setting.

[0076] Also, by changing the rotation direction of the crank 40 from bilateral forward rotation to unilateral forward rotation, the loads on TA, VM, RF, and MH increase. In particular, by changing the rotation direction of the crank 40 to bilateral forward rotation or unilateral forward rotation, the loads on RF and TA become extremely high. Therefore, when one side of TA, VM, RF, and MH is the muscle part to be strengthened, the recommended setting calculation unit 211 sets unilateral forward rotation as the recommended setting. That is, when the muscle parts on the left side of TA, VM, RF, and MH are to be strengthened, the recommended setting calculation unit 211 sets the unilateral forward rotation on the left side as the recommended setting. In this case, the user U fixes the left foot to the pedal 31L with a belt or the like and performs a pedaling motion.

[0077] Also, by changing the rotation direction of the crank 40 from bilateral reverse rotation to bilateral reverse rotation, the loads on RF, TA, and MH increase. In particular, by changing the rotation direction of the crank 40 from bilateral reverse rotation to bilateral reverse rotation of both legs, the load on TA becomes extremely high. Therefore, when one side of RF, MH, and TA is the muscle part to be strengthened, the recommended setting calculation unit 211 sets unilateral forward rotation as the recommended setting. That is, when the muscle parts on the left side of RF, MH, and TA are to be strengthened, the recommended setting calculation unit 211 sets the unilateral forward rotation on the left side as the recommended setting.

[0078] In this way, when it is desired to focus on strengthening the muscle parts on either the left or right side, the recommended setting calculation unit 211 sets the unilateral forward rotation or unilateral reverse rotation by that leg as the recommended setting.

[0079] Next, as a setting item, the rotational speed of the crank 40 will be described. Here, the low-speed rotation is set at 30 rotations per minute, and the high-speed rotation is set at 70 rotations per minute. By changing the rotational speed from low-speed rotation to high-speed rotation, the loads on TA, SOL, MG, RF, VM, and MH increase. When the muscle parts to be trained are TA, SOL, MG, RF, VM, and MH, the recommended setting calculation unit 211 sets one-sided forward rotation as the recommended setting. Here, the higher the rotational speed, the greater the load. Note that the rotational speed of the crank 40 may be set in two steps such as low-speed rotation and high-speed rotation, or may be set in three or more steps. Alternatively, the user U may input the numerical value of the actual rotational speed (rpm).

[0080] The pitch sound generated during the pedaling motion will be described. The pitch sound is a sound generated at a constant repetition period. By having the user U perform the pedaling motion while listening to the pitch sound, the rotational speed can be kept constant. That is, the load applied to the muscles can be adjusted according to the presence or absence of the pitch sound and its period. By changing from no pitch sound to having a pitch sound, the loads on SOL, VM, and MH can be increased.

[0081] Therefore, when the muscle parts to be trained are SOL, VM, and MH, the recommended setting calculation unit 211 sets having a pitch sound as the recommended setting. The rotational driving speed can be controlled by the pitch sound. Not only can the rotational driving be made smooth, but the activities of the lower limb extension group can be promoted. Therefore, it becomes possible to apply it to patients for the purpose of facilitating the lower limb extension group.

[0082] Next, the setting item regarding the knee extension angle of the knee joint will be described. Here, the state where the knee joint is not bent, that is, the knee extension angle in the state where the knee is fully extended, is set as 0 degrees, and it will be described such that the knee extension angle increases as the knee joint is bent. For example, the knee extension angle is 0 degrees when the angle formed by the thigh and the lower leg is parallel, and the knee extension angle is 90 degrees when the angle formed by the thigh and the lower leg is a right angle.

[0083] The maximum knee extension angle means the angle in the state where the knee joint angle is most extended while the crank 40 rotates 360 degrees around the rotation axis 21. Here, the electromyogram is measured respectively in the states where the maximum knee extension angles are 0 degrees, 30 degrees, and 60 degrees. That is, the measurement with the maximum knee extension angle of 0 degrees, the measurement with 30 degrees, and the measurement with 60 degrees are performed. Hereinafter, the change in load obtained from the measurement results of three times with different maximum knee extension angles will be described.

[0084] When the maximum knee extension angle is 0 degrees, the knee joint is in a completely extended state, so the range of motion of the knee joint is the largest. Also, in the order of the maximum knee extension angles of 0 degrees, 30 degrees, and 60 degrees, the range of motion of the knee joint shrinks. That is, as the maximum knee extension angle increases, the pedaling motion can be performed without fully extending the knee, so the load decreases.

[0085] The increase in load due to changing the maximum knee extension angle from the flexed side to the extended side will be described. That is, the range of load by widening the range of motion of the knee joint to the extended side by approaching the maximum knee extension angle to 0 degrees will be described. By approaching the maximum knee extension angle to 0 degrees, the loads on the TA, SOL.MG, RF, VA, and MH increase. Therefore, when the muscle parts to be trained are the TA, SOL.MG, RF, VA, and MH, the recommended setting calculation unit 211 makes a recommended setting to approach the maximum knee extension angle to 0 degrees.

[0086] Regarding the maximum knee extension angle, it can be adjusted based on a setting item that changes the pedaling motion posture of the user U. That is, by changing a setting item that changes the geometric arrangement of each component, the maximum knee extension angle can be widened to the extended side (approaching 0°). For example, the maximum knee extension angle can be adjusted by changing the front-rear distance between the chair 10 and the main body 20, or the tilt angle of the main body 20.

[0087] (Pedaling posture) Next, the setting items related to the geometric arrangement for changing the pedaling posture of user U will be described. FIGS. 4 to 7 are side views showing the posture of user U. Note that in FIGS. 4 to 7, some components are omitted. For example, in FIG. 4, only the pedal 31 and the link 30 of the exercise device 100 are shown, and the configurations of the main body 20, the installation base 15, the crank 40, etc. are appropriately omitted.

[0088] FIG. 4 is a diagram showing the postures when the installation distance between the main body 20 and the chair 10 in the front-rear direction is changed. In the X direction, three postures are shown when the installation distance of the chair 10 with respect to the main body 20 is normal, far, and near. That is, in FIG. 4, the postures when the installation distance between the main body 20 and the chair 10 is moved away from and closer to the normal case are shown. When the setting item is the installation distance between the main body 20 and the chair 10, the parameter is classified into three levels: long distance, normal distance, and short distance. That is, for the setting item of the installation distance between the main body 20 and the chair 10, the recommended setting calculation unit 211 recommends one of long distance, normal distance, and short distance as the recommended setting.

[0089] By changing the position of at least one of the chair 10 and the main body 20, the installation distance (front-rear direction distance) between the main body 20 and the chair 10 changes. By moving the chair 10 further away from the main body 20, the knee extension angle can be widened on the extension side. The range of motion of the knee joint, ankle joint, etc. can be adjusted according to the distance between the main body 20 and the chair 10. Therefore, the muscle parts that can be trained in the training and the load amount can be changed.

[0090] FIG. 5 is a diagram showing a user's posture when the installation angle of the main body 20 is inclined. FIG. 5 shows two postures when the distance between the chair 10 and the main body 20 is usually far. For example, by detaching the installation base 15 shown in FIGS. 1 and 2, the installation angle (tilt angle) of the main body 20 can be changed. In FIG. 5, the main body 20 is arranged on the installation base 15 so that the front of the main body 20 is higher than that in FIG. 4. That is, by arranging the main body 20 on the installation base 15, the main body 20 is inclined so as to descend rearward. According to the installation angle of the main body 20, the range of motion of the knee joint and ankle joint can be adjusted. By increasing the tilt angle of the main body 20, the ankle joint can be dorsiflexed.

[0091] The posture of the user U changes according to the installation angle of the main body 20. In FIG. 4, the main body 20 is arranged horizontally, and in FIG. 5, the main body 20 is arranged inclined. The range of motion of the knee joint and ankle joint can be adjusted according to the presence or absence of the installation base 15. When the setting item is the installation angle of the main body 20, the parameter is classified into two stages: with inclination and without inclination. That is, for the setting item of the installation angle of the main body 20, the recommended setting calculation unit 211 recommends either with inclination or without inclination of the main body 20 as the recommended setting. Therefore, the muscle parts that can be trained in training and the amount of load on them can be changed.

[0092] Furthermore, the angles of the knee joint and ankle joint change according to the installation angle of the main body 20. Therefore, by classifying the installation angle of the main body 20 in detail, the range of motion of the knee joint and ankle joint can be adjusted in detail. That is, the recommended setting calculation unit 211 recommends the numerical value or numerical range of the tilt angle of the main body 20 as the recommended setting. Alternatively, the recommended setting calculation unit 211 may recommend the numerical value or numerical range of the height or installation position of the main body 20 as the recommended setting. Thereby, the posture and load can be set in more detail. The muscle parts that can be trained in training and the amount of load on them can be changed by the tilt angle of the main body 20 and the installation base 15.

[0093] FIG. 6 is a diagram showing a user's posture when the pedal 31 is tilted. In FIG. 6, an adjusting member 38 for tilting the pedal 31 is attached to the pedal 31. For example, by disposing the adjusting member 38 between the pedal 31 and the link 30 shown in FIGS. 1 and 2, the angles of the knee joint, ankle joint, etc. can be adjusted. FIG. 6 shows two postures when the distance between the chair 10 and the main body 20 is usually far.

[0094] For example, the adjusting member 38 is a wedge-shaped block. By inserting the adjusting member 38 between the pedal 31 and the link 30, the pedal 31 can be tilted in the dorsiflexion direction. The angle of the ankle joint etc. changes according to the installation angle of the pedal 31. Since the angle of the ankle joint changes according to the installation angle of the pedal 31, the ankle joint can be tilted in the dorsiflexion direction.

[0095] In the configuration of FIG. 6, the ankle joint can be tilted in the dorsiflexion direction more than the configuration of FIG. 4. In FIG. 4, since the adjusting member 38 is not provided, the pedal 31 is not tilted in the dorsiflexion direction. In FIG. 6, since the adjusting member 38 is provided, the pedal 31 is tilted in the dorsiflexion direction compared to FIG. 4. Therefore, the posture of the user U changes according to the installation angle of the pedal 31.

[0096] The range of motion of the knee joint, ankle joint, etc. can be adjusted according to the presence or absence of the adjusting member 38. Of course, not limited to the configuration of detaching and attaching the adjusting member 38, the angle of the ankle joint may be adjusted by changing the shape of the pedal 31. For example, a wedge-shaped pedal 31 can be used.

[0097] When the setting item is the installation angle of the pedal 31, the parameter is classified into two stages: with pedal tilt and without pedal tilt. That is, for the setting item of the installation angle of the pedal 31, the recommended setting calculation unit 211 recommends either with pedal tilt or without pedal tilt as the recommended setting. Therefore, the muscle parts that can be trained in training and the load amount thereof can be changed.

[0098] Furthermore, by preparing a plurality of adjustment members 38 with different angles, it becomes possible to finely adjust the ankle joint angle. According to the user U, an assistant or the like may replace the adjustment member 38. For example, by the assistant replacing the adjustment member 38 with an adjustment member 38 having a larger wedge angle, the ankle joint can be tilted more in the dorsiflexion direction. Of course, the adjustment member 38 may be installed so as to tilt the ankle joint angle in the plantar flexion direction. For example, the insertion direction of the wedge-shaped adjustment member 38 may be reversed. Furthermore, the shape of the adjustment member 38 is not limited to a wedge shape and can be various shapes.

[0099] Therefore, by replacing the adjustment member 38 or the like, the tilt angle of the pedal 31 can be finely adjusted. According to the shape, angle, position, etc. of the adjustment member 38, the range of motion of the ankle joint can be adjusted more finely. According to the tilt angle of the pedal 31, the angles of the knee joint and ankle joint change. Therefore, by finely classifying the installation angle of the pedal 31, the range of motion of the knee joint and ankle joint can be finely adjusted. That is, the recommended setting calculation unit 211 recommends the numerical value or numerical range of the tilt angle of the pedal 31 as a recommended setting. Alternatively, the recommended setting calculation unit 211 may recommend the numerical value or numerical range of the height or angle of the adjustment member 38 as a recommended setting. Thereby, the posture and load can be set more finely. Depending on the tilt angle of the pedal 31 and the adjustment member 38, the muscle parts that can be trained in the training and the amount of load thereon can be changed.

[0100] FIG. 7 is a diagram showing the user posture when the tilt table 50 is provided. In FIG. 7, two postures are shown when the distance between the chair 10 and the main body 20 is usually far. For example, the tilt table 50 shown in FIGS. 1 and 2 is attached. Therefore, when there is a tilt table, the ankle joint can be tilted in the plantar flexion direction compared to the case without a tilt table.

[0101] The user's posture changes depending on the presence or absence of the inclined table 50. The range of motion of the knee joint, ankle joint, etc. can be adjusted according to the presence or absence of the inclined table 50. When the setting item is the presence or absence of the inclined table 50, its parameters are classified into two levels: with inclined table and without inclined table. That is, for the setting item of the inclined table 50, the recommended setting calculation unit 211 recommends either with inclined table or without inclined table as the recommended setting. Therefore, the muscle parts that can be trained during training and the amount of load on them can be changed.

[0102] Furthermore, the user's posture changes according to the inclination angle and the front-rear direction position of the inclined table 50. By replacing the inclined table 50 with different inclination angles, the inclination angle of the inclined table 50 can be changed. Therefore, it becomes possible for the user U to perform a foot paddling motion with the ankle joint in an appropriate range of motion. Alternatively, by changing the front-rear direction position of the inclined table 50, the ankle joint can be set to an appropriate range of motion. In this way, by changing the geometric arrangement of the inclined table 50, the angle of the ankle joint can be adjusted more finely. For the setting item of the inclined table 50, the recommended setting calculation unit 211 may calculate the numerical value and numerical range of the inclination angle and the mounting position (X coordinate) of the inclined table 50 as the recommended setting. Therefore, the muscle parts that can be trained during training and the amount of load on them can be changed.

[0103] (Example of parameter setting) Using FIGS. 8 to 10, an example of the process for setting the recommended setting will be described. Each of FIGS. 8 to 10 is a flowchart for showing the process of setting the recommended setting.

[0104] In FIG. 8, a process for calculating recommended settings is shown for the setting items of the presence or absence of a backrest and the installation distance between the main body 20 and the chair 10. As shown in FIG. 8, the processing system 200 inquires of the user U or the like whether or not to move the trunk muscles (S101). For example, the display of the output unit 230 displays a message such as "Move the trunk muscles?" When the user U or the like inputs that they do not move the trunk muscles (NO in S101), the recommended setting calculation unit 211 recommends having a backrest (S102). The output unit 230 outputs having a backrest as the recommended setting. The user U sits on the chair 10 having the backrest portion 12 and performs a foot pumping motion. And the installation distance between the main body 20 and the chair 10 is the normal distance.

[0105] When the user U or the like inputs that they move the trunk muscles (YES in S101), the recommended setting calculation unit 211 recommends having no backrest as the recommended setting (S103). Next, the processing system 200 inquires of the user U or the like whether or not to move the erector spinae muscles more (S104).

[0106] When the user U or the like inputs that they do not move the erector spinae muscles more (NO in S104), the recommended setting calculation unit 211 recommends setting the installation distance between the main body 20 and the chair 10 to a short distance (S105). The output unit 230 outputs having no backrest and setting the installation distance between the main body 20 and the chair 10 to a short distance as the recommended setting. The user U sits on the chair 10 without the backrest portion 12. With the installation distance between the main body 20 and the chair 10 being in the short distance state, the user U performs a foot pumping motion.

[0107] When the user U or the like inputs that they move the erector spinae muscles more (YES in S104), the recommended setting calculation unit 211 recommends setting the installation distance between the main body 20 and the chair 10 to a long distance (S106). The output unit 230 outputs having no backrest and setting the installation distance between the main body 20 and the chair 10 to a long distance as the recommended setting. The user U sits on the chair 10 without the backrest portion 12. And with the installation distance between the main body 20 and the chair 10 set to the long distance state, the user U performs a foot pumping motion. Thus, the processing ends.

[0108] Figure 9 shows a process of setting the presence or absence of inclination of the pedal 31 and the setting item of the installation distance between the main body 20 and the chair 10. As shown in Figure 9, the processing system 200 inquires of the user U or the like whether or not to row in the dorsiflexion region of the ankle joint (S201). When the user U or the like inputs that they do not row in the dorsiflexion region (NO in S201), the recommended setting calculation unit 211 recommends no pedal inclination (S202). The output unit 230 outputs no pedal inclination as the recommended setting. That is, the user U performs a rowing motion with the adjusting member 38 for inclining the pedal 31 to the dorsiflexion side removed.

[0109] When the user U or the like inputs that they row in the dorsiflexion region (YES in S201), the recommended setting calculation unit 211 recommends having pedal inclination (S203). Next, the processing system 200 inquires of the user U or the like whether or not to move the soleus muscle (deep muscle) (S204).

[0110] When the user U or the like inputs that they do not move the soleus muscle more (NO in S204), the recommended setting calculation unit 211 recommends setting the installation distance between the main body 20 and the chair 10 to a long distance (S205). The output unit 230 outputs having pedal inclination and setting the installation distance between the main body 20 and the chair 10 to a long distance as the recommended setting. The user U or the like attaches the adjusting member 38 for inclining the pedal 31 to the dorsiflexion side. The user U performs a rowing motion with the installation distance between the main body 20 and the chair 10 set to a long distance.

[0111] When the user U or the like inputs that they move the soleus muscle (YES in S204), the recommended setting calculation unit 211 recommends setting the installation distance between the main body 20 and the chair 10 to a short distance (S206). The output unit 230 outputs having pedal inclination and setting the installation distance between the main body 20 and the chair 10 to a short distance as the recommended setting. The user U or the like attaches the adjusting member 38 for inclining the pedal 31 to the dorsiflexion side. The user U performs a rowing motion with the installation distance between the main body 20 and the chair 10 set to a short distance. In this way, the process ends.

[0112] Figure 10 shows the process of setting the presence or absence of the inclined table 50 and the setting item of the installation distance between the main body 20 and the chair 10. As shown in Figure 10, the processing system 200 asks the user U or the like whether to row in the plantar flexion region of the ankle joint (S301). When the user U or the like inputs that they do not row in the plantar flexion region (NO in S301), the recommended setting calculation unit 211 recommends no inclined table (S302). The output unit 230 outputs no inclined table as the recommended setting. That is, the user U removes the inclined table 50 for tilting the pedal 31 to the plantar flexion side and performs the rowing motion.

[0113] When the user U or the like inputs that they row in the plantar flexion region (YES in S301), the recommended setting calculation unit 211 recommends having an inclined table (S303). Next, the processing system 200 asks the user U or the like whether to move the gastrocnemius muscle (S304).

[0114] When the user U or the like inputs that they do not move the gastrocnemius muscle (NO in S304), the recommended setting calculation unit 211 recommends setting the installation distance between the main body 20 and the chair 10 to a long distance (S305). The output unit 230 outputs having an inclined table and setting the installation distance between the main body 20 and the chair 10 to a long distance as the recommended setting. The user U attaches the inclined table 50 for tilting the pedal 31 to the plantar flexion side. Then, with the installation distance between the main body 20 and the chair 10 set to a long distance, the user U performs the rowing motion.

[0115] When the user U or the like inputs that they move the gastrocnemius muscle (YES in S304), the recommended setting calculation unit 211 recommends setting the installation distance between the main body 20 and the chair 10 to a short distance (S306). The output unit 230 outputs having an inclined table and setting the installation distance between the main body 20 and the chair 10 to a short distance as the recommended setting. The user U attaches the inclined table 50 for tilting the pedal 31 to the plantar flexion side and performs the rowing motion. The front - rear direction distance between the main body 20 and the chair 10 is a long distance. In this way, the process ends.

[0116] In the above processing, for the setting items without recommended settings, the default settings may be used. That is, parameters (numerical values, levels, presence or absence of devices, etc.) serving as default settings may be provided in advance for each setting item. And for the setting items without recommended settings, the user U can perform training with the parameters serving as default settings. Also, the parameters serving as default settings may be changed for each user. That is, the parameters of the default settings can be changed according to the user data.

[0117] The recommended setting may indicate a change from the default setting. For example, when raising or lowering the level from the default level, when the default setting is without a device, having a device can be set as the recommended setting. Or, when the default setting is having a device, not having a device can be set as the recommended setting. Also, setting the default setting as the recommended setting is also possible. Or, when the default setting is having a device, having a device can be set as the recommended setting. Of course, the recommended setting may be a specific numerical value or numerical range.

[0118] A training system that can be personalized according to the user U can be provided. For example, the user U can perform optimal training by inputting the muscle part to be trained and the load amount thereof. Also, for the user U who has been injured, parameters with reduced load on the injured part can be set.

[0119] In the processing system 200, the setting items of the exercise device 100 are associated according to the muscle part. The processing system 200 stores in a memory or the like by associating the setting items highly correlated with the muscle part. The recommended setting calculation unit 211 can obtain appropriate recommended settings for each user U.

[0120] The simulator 212 changes the parameters of the setting items of the exercise equipment 100 and simulates the load applied to each muscle part. The simulator 212 calculates the temporal change in muscle activity during one rotation of the crank 40. The recommended setting calculation unit 211 calculates the recommended setting from this simulation result. For example, the recommended setting calculation unit 211 calculates the recommended setting by referring to the simulation results of a physique similar to the user data. By doing so, an appropriate recommended setting can be calculated. The recommended setting calculation unit 211 can recommend appropriate numerical values and levels as the parameters of the setting items. Therefore, effective training can be performed.

[0121] The user U or the like may input a muscle part such as the soleus muscle that they want to train. Thereby, an effective load can be applied to the deep muscles that are difficult to train in normal training. Therefore, effective training becomes possible.

[0122] FIG. 11 and FIG. 12 are graphs showing an example of the simulation results by the simulator. FIG. 11 is a graph showing the change in load due to geometric arrangement. Specifically, FIG. 11 shows the muscle activity of the rectus abdominis muscle on the left and right and the erector spinae muscle. FIG. 11 shows the simulation results in the case of the reference setting (FIG. 4), with overall inclination (FIG. 5), with pedal inclination (FIG. 6), and with an inclined platform (FIG. 7) when the set distance is the normal distance. Further, FIG. 11 shows the simulation results in the case where the set distance of the reference setting is the long distance (FIG. 4), with long distance and overall inclination (FIG. 5), with long distance and pedal inclination (FIG. 6), and with long distance and inclined platform (FIG. 7).

[0123] As shown in FIG. 11, when the installation distance is the normal distance and the geometric arrangement is changed, the muscle activity of the rectus abdominis muscle decreases. Even if the installation distance is the long distance and the geometric arrangement is changed, there is almost no change in the rectus abdominis muscle.

[0124] Figure 12 is a graph showing the change in load according to the installation distance. Figure 12 shows the muscle activity levels of the soleus muscle and the gastrocnemius muscle. In Figure 12, the parameter of the installation distance is changed to the normal distance, the short distance, and the long distance (see Figure 4). Also, Figure 12 shows the simulation results in the case of having an overall inclination (see Figure 5), the case of having a pedal inclination (see Figure 6), and the case of having an inclined platform (see Figure 7). In the simulation results in the case of having an overall inclination (see Figure 5), the case of having a pedal inclination (see Figure 6), and the case of having an inclined platform (see Figure 7), the installation distance is changed to the normal distance or the long distance.

[0125] As shown in Figure 12, in the case of having a pedal inclination, when the installation distance becomes the long distance, the muscle activity level decreases. In the case of having an inclined platform, when it is at the long distance, the muscle activity level becomes high. Except for the case of having an inclined platform, the muscle activity level becomes small. Therefore, as in the flowchart shown in Figure 9, the parameters can be determined.

[0126] Figures 13 to 22 are graphs showing the simulation results by the simulator. Figures 13 to 22 are graphs showing the change in the muscle activity level of each muscle part when the crank angle is changed. In Figures 13 to 22, the horizontal axis represents the crank angle and the vertical axis represents the muscle activity level. Figures 13, 15, 17, 19, and 21 are graphs showing the muscle activity of the right half of the body. Figures 14, 16, 18, 20, and 22 are graphs showing the muscle activity of the left half of the body.

[0127] Figures 13 and 14 are graphs showing the simulation results under the reference setting (the normal distance in Figure 4). Figures 15 and 16 are graphs showing the simulation results when the installation distance is the short distance (the short distance in Figure 4). Figures 17 and 18 are graphs showing the simulation results when the installation distance is the long distance (the long distance in Figure 4). Figures 19 and 20 are showing the simulation results in the case of having a pedal inclination (the normal distance in Figure 6). Figures 21 and 22 are showing the simulation results in the case of having an inclined platform (the normal distance in Figure 7).

[0128] The simulator 212 dynamically calculates muscle activity levels. That is, the simulator 212 calculates the muscle activity levels corresponding to the crank angle during pedaling. For example, the simulator 212 changes the crank angle at regular intervals and calculates the muscle activity levels at each crank angle. The simulator 212 calculates the muscle activity levels for each muscle part. In this way, by changing the installation distance and geometric arrangement, the muscle activity levels change. Therefore, by changing the parameters of the exercise device 100, the muscle parts to be trained can be changed. Therefore, as described above, the processing system 200 can calculate appropriate recommended settings according to the acquired muscle part data.

[0129] The processing system 200 may be shared by a plurality of exercise devices 100. That is, in a rehabilitation center or the like where a plurality of exercise devices 100 are installed, one computer may be installed as the processing system 200. Then, one computer serving as the processing system 200 can calculate the recommended settings for the plurality of exercise devices 100. Of course, the processing of the recommended setting calculation unit 211 and the simulator 212 may be performed by a server device, and the processing of the input unit 201 and the output unit 230 may be performed by an edge device or a terminal on the user U side. The human body computer model is not limited to the human body finite element model, and other human body models can be used.

[0130] Also, part or all of the processing in the above-described processing system 200 or the like can be realized as a computer program. Such a program can be stored using various types of non-transitory computer-readable media and supplied to a computer. Non-transitory computer-readable media include various types of tangible recording media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROM (Read Only Memory), CD-R, CD-R / W, semiconductor memories (e.g., mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (Random Access Memory)). Also, the program may be supplied to a computer by various types of transitory computer-readable media. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves. The transitory computer-readable media can supply the program to a computer via wired communication paths such as electric wires and optical fibers, or wireless communication paths.

[0131] Note that the present invention is not limited to the above-described embodiments and can be appropriately modified without departing from the gist.
