DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] The present invention will be described below through embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. In addition, not all of the configurations described in the embodiments are necessarily essential as means for solving the problems. For clarity of explanation, the following description and drawings are omitted and simplified as appropriate. In each drawing, the same elements are given the same reference numerals, and repeated explanations are omitted as necessary.

[0027] Embodiment 1 In this embodiment, a foot-rowing exercise machine will be described as an example of training machine. The training machine is a foot-rowing exercise machine (hereinafter, simply referred to as an exercise machine) for a user to perform foot-rowing exercise. The processing system and processing method according to this embodiment perform processing for recommending recommended settings for the setting items of the machine when training with the foot-rowing exercise machine. For example, the processing system outputs the recommended settings to a trainee performing foot-rowing exercise and an assistant assisting the training. In this way, the trainee can train with an appropriate load.

[0028] The exercise device 100 will be described with reference to Figs. 1 and 2. Figs. 1 and 2 are views of the exercise device 100 as seen from the side. In the following description, for clarity, an XYZ three-dimensional Cartesian coordinate system will be used. Specifically, the +X direction is the forward direction, the -X direction is the backward direction, the +Y direction is the upward direction, the -Y direction is the downward direction, the +Z direction is the leftward direction, and the -Z direction is the rightward direction. The forward / backward, leftward, rightward, and upward directions are directions based on the direction of the user U.

[0029] The exercise machine 100 is capable of adjusting the range of motion of the ankle joint. In the following description, the rotation direction of the ankle joint around the Z axis is referred to as the plantar flexion direction, and the angle is referred to as the plantar flexion angle. More specifically, the direction in which the toes of the foot FT point downward is referred to as the plantar flexion direction, and the direction in which the toes point upward is referred to as the dorsiflexion direction.

[0030] As shown in FIG. 1, the exercise device 100 has a main body 20, a link 30, a crank 40, and an inclined platform 50. A chair 10 is provided behind the exercise device 100. A user U performs pedaling exercise while seated on the chair 10. Therefore, the chair 10 serves as a seat on which the user U sits. The chair 10 may be provided integrally with the exercise device 100 or may be provided separately. For example, the chair 10 may be a chair in a facility or home where the user U is. In other words, the user U or an assistant may set up the chair 10 behind the exercise device 100.

[0031] The chair 10 includes a seat portion 11 serving as a seating portion, and a backrest portion 12. When the user U sits on the seat portion 11, the backrest portion 12 supports the back of the user U. In other words, the user U can perform a pedaling exercise while leaning against the backrest portion 12. The chair 10 is replaceable or adjustable to suit the user U. For example, a chair 10 without the backrest portion 12 can be used for a user U who performs training with a higher load. Alternatively, the backrest portion 12 may have a reclining mechanism. The angle of the backrest portion 12 may be adjusted by the reclining mechanism.

[0032] In the exercise device 100, the components attached to the main body 20 are symmetrical. In FIG. 2, in order to distinguish between the left and right components, the components on the left side of the main body 20 are marked with L, and the components on the right side are marked with R. For example, in FIG. 2, the left inclined platform 50 is shown as inclined platform 50L, and the right inclined platform 50 is shown as inclined platform 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 the left and right components are not distinguished, L and R are omitted.

[0033] The main body 20 rotatably holds the crank 40. For example, the main body 20 is provided with a rotating shaft 21. 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 motion of the crank 40. Note that the main body 20 may have a gear or the like for making the load variable.

[0034] The main body 20 is disposed on the installation stand 15. The installation stand 15 is disposed on the floor surface. For example, the front part of the main body 20 is disposed on the installation stand 15, and the rear part is disposed on the floor surface. The installation angle of the main body 20 can be changed by changing the height, position, etc. of the installation stand 15. For example, by removing the installation stand 15, the main body 20 is disposed horizontally. Also, by raising the installation stand 15, the installation angle of the main body 20 becomes steeper. In this way, by changing the height of the installation stand 15 or removing the installation stand 15, the posture of the user U during training changes. Therefore, the range of motion of the joints during the user U's training can be adjusted.

[0035] Also, the distance in the front-rear direction between the main body 20 and the chair 10 may be changed depending on the user U. For example, the user U can place the chair 10 closer to the main body 20. This allows the user U to perform pedaling exercise with the knee joints and the like relatively bent. Alternatively, the user U can place the chair 10 farther away from the main body 20. This allows the user U to train with the knee joints 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 during the user U's training can be adjusted.

[0036] 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 the 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 midway along the link 30. The pedal 31 serves as a step (footrest) on which the user U places his / her foot FT. The user U, who is seated, places his / her foot FT on the pedal 31.

[0037] The sliding wheel 35 is attached to the link 30 via a rotating shaft (axle). In other words, 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 platform 50.

[0038] 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 hip joint so as to step on the foot FT. This causes the crank 40 to rotate around the rotation axis 21. Furthermore, the angle between the link 30 and the crank 40 changes according to the rotation of the crank 40. 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 called the crank angle). Furthermore, the sliding wheel 35 moves in the forward and backward directions while in contact with the inclined surface. As a result, the crank 40 and the link 30 rotate according to the pedaling motion so that the pedal 31 describes an elliptical orbit.

[0039] The pedal 31, the gliding wheel 35, the link 30, the crank 40, and the tilt table 50 are provided for the left and right feet FT of the user U, respectively. That is, the pedal 31, the gliding wheel 35, the link 30, the crank 40, and the tilt table 50 are provided on the left and right sides of the main body 20, respectively. The pedal 31R, the gliding wheel 35R, the link 30R, the tilt 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 tilt table 50L provided on the left side of the main body 20 correspond to the left foot FTL of the user U.

[0040] The crank 40 is attached to the rotating shaft 21 of the main body 20 so as to be in opposite phase to the left and right feet FT. In other words, the crank 40 for the left foot and the crank 40 for the right foot are out of rotation by 180°. The user U performs a pedaling exercise by alternately extending and shortening the left and right legs.

[0041] A sliding wheel 35 is attached to the lower end of the link 30. The sliding wheel 35 has a wheel that slides on the slope of the slope 50. The slope 50 has a slope that becomes higher toward the rear. The sliding wheel 35 moves back and forth in the X direction (front-rear direction) according to the rotational motion of the link 30. As shown in FIG. 1, while the user U stretches his right leg and pedals in a direction bending the left leg, the right sliding wheel 35 moves forward and the left sliding wheel 35 moves backward. As shown in FIG. 2, while the user U stretches his left leg and pedals in a direction bending the right leg, the left sliding wheel 35 moves forward and the right sliding wheel 35 moves backward.

[0042] The height of the sliding wheel 35 changes along the inclined surface of the ramp 50. The further rearward the ramp 50 is, the higher the inclined surface becomes. In other words, the ramp 50 is an uphill slope relative to the sliding wheel 35 moving backward. Therefore, while the sliding wheel 35 is moving backward, the sliding wheel 35 gradually becomes higher. Conversely, while the sliding wheel 35 is moving forward, the sliding wheel 35 gradually becomes lower. The angle of the link 30 is determined according to the height of the sliding wheel 35.

[0043] Here, the angle of the pedal 31 provided on the link 30 is limited according to the height of the sliding wheel 35. That is, when the sliding wheel 35 is higher, the pedal 31 rotates in the plantar flexion direction. When the sliding wheel 35 is lowered, the pedal 31 rotates in the dorsiflexion direction. Therefore, the movable range of the plantar and dorsiflexion angle of the ankle joint can be adjusted according to the inclination angle of the inclined platform 50. The movable range of the plantar and dorsiflexion angle of the ankle joint can be adjusted according to the rotation angle of the crank 40.

[0044] A user U performs a pedaling exercise on the exercise machine 100 for training. In other words, by performing a pedaling exercise, the user U can apply a load to the muscles of the lower limbs and the trunk. Muscles that can be trained with the exercise machine 100 include the erector spinae (PS), rectus abdominis (RA), external oblique (OEA), hip flexors (HF), gluteus maximus (GM), rectus femoris (RF), tibialis anterior (TA), soleus (SOL), gastrocnemius (MG), vastus medialis (VM), hamstring (MH), and the like. In addition, the user U or an assistant can specify one or more muscle parts that they want to train.

[0045] (Setting items) Here, the exercise device 100 allows parameters to be set for various setting items. The user U or the like can change the parameters for each setting item to perform effective training. By changing the parameters for each setting item of the exercise device 100, the user U can adjust the muscle parts that can be trained by the pedaling exercise and the load on those parts. This allows for effective training. Note that the parameter settings for each setting item may not only be performed by the user U who performs the training, but may also be performed by an assistant who assists the training. The assistant may be a physical therapist, an occupational therapist, or the like.

[0046] The setting items of the exercise machine 100 include, for example, the rotation speed of the crank 40, the load of the crank 40, and the rotation direction of the crank 40. For example, it is possible to apply a high load to the muscles by increasing the rotation speed or the load of the crank 40. Furthermore, it is possible to change the muscle part to which the load is applied by changing the rotation direction of the crank 40.

[0047] Other setting items include settings for changing the geometric arrangement of the exercise machine 100. Such setting items include the distance between the chair 10 and the main body 20 in the front-rear direction, 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. The range of motion angles of the ankle joint can be changed according to the front-rear position of the tilt table 50 and the tilt angle of the tilt table 50. In addition, the range of motion angles of the knee joint and hip joint can be changed by changing the distance between the main body 20 and the chair 10 in the front-rear direction and the tilt angle of the main body 20. In other words, the posture during training can be changed by changing the parameters of the setting items. By changing the parameters of such setting items, the muscle parts to be trained and the load amount can be adjusted.

[0048] Another setting item is whether or not the backrest 12 is provided. For example, if a chair 10 with a detachable backrest 12 is prepared, the backrest 12 can be removed when training at a high load. Alternatively, a chair 10 with a backrest 12 and a chair without a backrest 12 may be prepared, and the chair 10 may be changed depending on the training. In this way, a plurality of chairs 10 may be prepared, and the chair 10 may be changed depending on the training.

[0049] Other setting items do not require adjustment, modification, or replacement of the exercise device 100. For example, the posture or movement of the user U may be set as a setting item. Specific setting items include whether or not the user U has his / her arms crossed, and whether or not the user U swings his / her arms. For example, the setting item can be changed by the user U selecting whether or not to swing his / her arms during pedaling exercise. Alternatively, the parameter can be changed by the user U selecting whether or not to cross his / her arms. In this way, the muscle parts to be trained can be changed depending on the posture or movement of the user U.

[0050] In the exercise machine 100, various setting items can be set. In other words, by appropriately setting the parameters of the setting items, it is possible to apply an appropriate load to each muscle part. That is, it is possible to apply a desired load to each muscle part. For example, it is possible to apply a high load to a muscle part that the user U or the like wants to focus on training. Alternatively, it is possible to reduce the load or restrict the range of motion angle for an injured part.

[0051] As described above, the setting items include items that can be set as numerical parameters such as speed, angle, and relative position. Alternatively, the setting items include items that can be set in stages such as high level, medium level, and low level. In addition, the setting items include items that can be set depending on the presence or absence of equipment or action. In addition, the setting items include items that can be changed by arranging the equipment or replacing the equipment. In addition, the setting items include items that can be changed depending on the user's training posture or training action. For example, in some setting items, the action or the presence or absence of equipment can be used as a parameter.

[0052] A processing system capable of outputting recommended settings for the above setting items will be described. Fig. 3 is a block diagram showing the configuration of a processing system 200. The processing system 200 includes an input unit 201, a user data acquisition unit 202, a recommended setting calculation unit 211, a simulator 212, an output unit 230, and a determination unit 240.

[0053] The processing system 200 may be configured, for example, by a personal computer having a processor, a memory, etc. Therefore, the processing system 200 stores a processing program in advance. Then, the processor of the processing system 200 executes the program, thereby enabling the processing described below to be executed.

[0054] The input unit 201 includes input devices such as a touch panel, a keyboard, a mouse, etc. The user U or an assistant (hereinafter, collectively referred to as the user U, etc.) can input various information by operating the input unit 201. Alternatively, the input unit 201 may include a microphone for voice input.

[0055] The user data acquisition unit 202 acquires user data regarding the user U who is performing training. The user data includes physical information of the user U. For example, the user data includes the height, weight, length of the lower limbs, length of the upper limbs, length of the trunk, etc. Furthermore, the user data is not limited to physical characteristics, and may include other characteristics such as age and sex.

[0056] For example, the user U or the like operates the input unit 201 to input a numerical value such as height. As a result, 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, it is assumed that a user ID and user data are associated with each other 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 with each user. In this case, the user U or the like inputs the user ID, and the user data acquisition unit 202 reads the user data from the memory.

[0057] Furthermore, the user data acquisition unit 202 acquires user data including information on the daily living activities of the user U. For example, the user data includes information indicating whether the user U can perform daily living activities. Assume that the user U is an injured person, a sick person, a rehabilitation patient, an elderly person, or the like. In this case, the user U cannot perform some of the daily living activities due to injury, illness, aging, or the like. Then, when the user inputs whether or not the user can perform daily living activities, the user data acquisition unit 202 acquires user data including information on the daily living activities. The processing system 200 may store a user table in which information on daily living activities is associated with a user ID. In this case, the user U inputs the user ID, and the user data acquisition unit 202 reads the user data from the memory.

[0058] Examples of daily living activities include going up and down stairs, walking, walking with assistance, standing, sitting, standing and sitting with assistance, standing, standing with assistance, stable sitting, etc. For example, the user data includes information indicating whether the user can go up and down stairs, whether the user can walk, whether the user can walk with assistance, whether the user can stand up, and whether the user can sit down. The user data also includes information indicating whether the user can stand up and sit with assistance, whether the user can stand, whether the user can stand with assistance, and whether the user can sit stably.

[0059] Here, the stair climbing and descending action is the action of walking on stairs, that is, the action of ascending or descending stairs. The walking action is the action of walking on a flat floor surface without the assistance of an assistant. The assisted walking action is the action of walking on a flat floor surface with the assistance of an assistant. The assisted walking action may also be the walking action with assistance from a walker or a cane. The standing up action is the action of standing up from a seated position in a chair. The sitting down action is the action of sitting down in a chair from a standing position. The assisted standing and sitting down action is the action of standing up and sitting down with the assistance of an assistant. The standing position is the action of maintaining a standing posture. The assisted standing position is the action of standing up with the assistance of an assistant. The stable sitting position is the action of the user U maintaining a stable sitting posture.

[0060] The degree of difficulty varies depending on the above daily living activities. For example, the order of difficulty is as follows: going up and down stairs, walking, walking with assistance, standing and sitting, standing and sitting with assistance, standing, standing with assistance, and stable sitting. Therefore, the possible daily living activities vary depending on the user's muscle strength, etc.

[0061] The user data does not need to include information indicating whether all daily living activities are possible. For example, it is sufficient to include information indicating whether one or more daily living activities are possible. Furthermore, it is preferable that the boundary between possible and impossible daily living activities is known. For example, it is preferable that the user data includes information indicating that walking is possible but that climbing up and down stairs is impossible. In other words, it is preferable that the user data includes information indicating to what extent daily living activities are possible.

[0062] The recommended setting calculation unit 211 calculates recommended settings for setting items based on user data. The recommended setting calculation unit 211 obtains recommended settings based on information on the activities of daily living that the user can perform. In the recommended settings, optimal parameters are set for each setting item.

[0063] (Setting items) Specific examples of setting items will be described below. Setting items related to the geometric arrangement for changing the pedaling posture of the user U will be described. Figs. 4 to 7 are side views showing the posture of the user U. Note that some components are omitted in Figs. 4 to 7. For example, Fig. 4 shows only the pedals 31 and links 30 of the exercise machine 100, and components such as the main body 20, the installation base 15, and the crank 40 are omitted as appropriate.

[0064] FIG. 4 is a diagram showing 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 to the main body 20 is normal, far, and close. That is, FIG. 4 shows postures when the installation distance between the main body 20 and the chair 10 is moved away and moved closer, based on the normal case. When the setting item is the installation distance between the main body 20 and the chair 10, the parameter is classified into three stages: 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.

[0065] By changing the position of at least one of the chair 10 and the main body 20, the installation distance (front-rear distance) between the main body 20 and the chair 10 changes. By moving the chair 10 farther away from the main body 20, the knee extension angle can be widened to 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 by training and the load on them can be changed.

[0066] FIG. 5 is a diagram showing the user's posture when the installation angle of the main body 20 is inclined. In FIG. 5, two postures are shown, one when the distance of the chair 10 to the main body 20 is normal and the other when it is far. For example, the installation angle (tilt angle) of the main body 20 can be changed by attaching and detaching the installation base 15 shown in FIG. 1 and FIG. 2. In FIG. 5, the main body 20 is placed on the installation base 15 so that the front of the main body 20 is higher than in FIG. 4. In other words, by placing the main body 20 on the installation base 15, the main body 20 is inclined so as to descend toward the rear. The movable range of the knee joint, ankle joint, etc. can be adjusted according to the installation angle of the main body 20. By increasing the inclination angle of the main body 20, the ankle joint can be in the dorsiflexion direction.

[0067] The posture of the user U changes depending on the installation angle of the main body unit 20. In FIG. 4, the main body unit 20 is arranged horizontally, and in FIG. 5, the main body unit 20 is arranged at an angle. The movable range of the knee joint, ankle joint, etc. can be adjusted depending on the presence or absence of the installation stand 15. When the setting item is the installation angle of the main body unit 20, the parameter is classified into two stages, tilted and not tilted. In other words, for the setting item of the installation angle of the main body unit 20, the recommended setting calculation unit 211 recommends either tilted or not tilted of the main body unit 20 as the recommended setting. Therefore, the muscle parts that can be trained by training and the load amount thereof can be changed.

[0068] Furthermore, the angles of the knee joint, ankle joint, etc. change depending on the installation angle of the main body part 20. Therefore, by finely classifying the installation angle of the main body part 20, the movable range of the knee joint, ankle joint, etc. can be finely adjusted. That is, the recommended setting calculation unit 211 recommends a value or a numerical range of the tilt angle of the main body part 20 as the recommended setting. Alternatively, the recommended setting calculation unit 211 may recommend a value or a numerical range of the height or installation position of the main body part 20 as the recommended setting. This allows the posture and load to be set more finely. The muscle parts that can be trained by training and the load amount thereof can be changed depending on the tilt angle of the main body part 20 and the installation stand 15. That is, the tilt angle of the main body part 20 can be changed depending on the presence or absence of the installation stand 15 shown in FIG. 1.

[0069] Fig. 6 is a diagram showing the user's posture when the pedal 31 is tilted. In Fig. 6, an adjustment member 38 for tilting the pedal 31 is attached to the pedal 31. For example, by disposing the adjustment 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 of the chair 10 to the main body 20 is normal and far.

[0070] For example, the adjustment member 38 is a wedge-shaped block. By inserting the adjustment member 38 between the pedal 31 and the link 30, the pedal 31 can be tilted in the dorsiflexion direction. The angles of the ankle joint and the like change depending on the installation angle of the pedal 31. Since the ankle joint angle changes depending on the installation angle of the pedal 31, the ankle joint can be tilted in the dorsiflexion direction.

[0071] In the configuration of Fig. 6, the ankle joint can be tilted in the dorsiflexion direction more than in the configuration of Fig. 4. In Fig. 4, the adjustment member 38 is not provided, so the pedal 31 is not tilted in the dorsiflexion direction. In Fig. 6, the adjustment member 38 is provided, so the pedal 31 is tilted in the dorsiflexion direction compared to Fig. 4. Therefore, the posture of the user U changes depending on the installation angle of the pedal 31.

[0072] The movable range of the knee joints, ankle joints, etc. can be adjusted depending on the presence or absence of the adjustment member 38. Of course, the angle of the ankle joint may be adjusted by changing the shape of the pedal 31, not limited to the configuration in which the adjustment member 38 is detached. For example, a wedge-shaped pedal 31 can be used.

[0073] When the setting item is the installation angle of the pedal 31, the parameter is classified into two stages, pedal inclined and pedal not inclined. In other words, for the setting item of the installation angle of the pedal 31, the recommended setting calculation unit 211 recommends either pedal inclined or pedal not inclined as the recommended setting. Therefore, it is possible to change the muscle parts that can be trained by training and the load amount thereof.

[0074] Furthermore, by preparing a plurality of adjustment members 38 with different angles, it becomes possible to finely adjust the ankle joint angle. An assistant or the like can replace the adjustment members 38 according to the user U. For example, the assistant can tilt the ankle joint further in the dorsiflexion direction by replacing the adjustment member 38 with an adjustment member 38 with a larger wedge angle. 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.

[0075] Therefore, by replacing the adjustment member 38, the inclination angle of the pedal 31 can be finely adjusted. The movable range of the ankle joint can be finely adjusted depending on the shape, angle, position, etc. of the adjustment member 38. The angles of the knee joint and the ankle joint change depending on the inclination angle of the pedal 31. Therefore, by finely classifying the installation angle of the pedal 31, the movable range of the knee joint and the ankle joint can be finely adjusted. That is, the recommended setting calculation unit 211 recommends a numerical value or a numerical range of the inclination angle of the pedal 31 as the recommended setting. Alternatively, the recommended setting calculation unit 211 may recommend a numerical value or a numerical range of the height or angle of the adjustment member 38 as the recommended setting. This allows the posture and the load to be set more finely. The inclination angle of the pedal 31 and the adjustment member 38 can change the muscle parts that can be trained by training and the load amount. The inclination of the pedal 31 by the adjustment member 38 is also called the pedal inclination.

[0076] Fig. 7 is a diagram showing the user's posture when the tilt table 50 is provided. Fig. 7 shows two postures, one when the distance of the chair 10 from the main body 20 is normal and the other when it is far. For example, the tilt table 50 shown in Figs. 1 and 2 is attached. Therefore, when the tilt table is provided, the ankle joint can be tilted in the plantar flexion direction compared to when the tilt table is not provided.

[0077] The user's posture changes depending on whether or not the tilt table 50 is present. The movable range of the knee joint, ankle joint, etc. can be adjusted depending on whether or not the tilt table 50 is present. When the setting item is whether or not the tilt table 50 is present, the parameter is classified into two stages, with tilt table and without tilt table. In other words, for the setting item of the tilt table 50, the recommended setting calculation unit 211 recommends either with tilt table or without tilt table as the recommended setting. Therefore, the muscle parts that can be trained by training and the load on them can be changed.

[0078] Furthermore, the user's posture changes depending on the inclination angle and the front-rear position of the inclined platform 50. The inclination angle of the inclined platform 50 can be changed by replacing the inclined platform 50 with one having a different inclination angle. Thus, the user U can perform pedaling exercise with the ankle joint in an appropriate range of motion. Alternatively, the ankle joint can be in an appropriate range of motion by changing the front-rear position of the inclined platform 50. In this way, the angle of the ankle joint can be adjusted more finely by changing the geometric arrangement of the inclined platform 50. The recommended setting calculation unit 211 may calculate the inclination angle of the inclined platform 50 and the numerical value or numerical range of the mounting position (X coordinate) as the recommended setting for the setting item of the inclined platform 50. Thus, the muscle parts that can be trained by training and the load amount thereof can be changed.

[0079] The recommended settings may include parameters for at least some of the above-mentioned setting items. In other words, the parameters for all of the above-mentioned setting items may not be changed. In other words, one or more of the multiple setting items may not be changed from the basic settings. In addition, the parameters of other setting items may be the recommended settings. For example, the parameters of a setting item related to the rotational motion of pedaling may be the recommended settings.

[0080] For example, the recommended setting calculation unit 211 stores a recommended setting table as shown in Fig. 8 in a memory or the like. In the recommended setting table, activities of daily living are associated with recommended settings. The recommended settings shown in Fig. 8 include recommended parameters for only three items: installation distance, pedal load, and rotation speed. Therefore, parameters for setting items other than installation distance, pedal load, and rotation speed are fixed.

[0081] The installation distance is the relative distance from the main body 20 to the chair 10. The installation distance is a parameter that can be adjusted by changing the distance from the main body 20 to the seat 11 of the chair 10. More specifically, the installation distance is the distance from the rotation axis 21 to the seat 11. The installation distance can be changed by the user U, etc., moving the chair 10 or the main body 20 back and forth. For example, the installation distance can be adjusted to three levels: long distance, normal distance, and short distance. When the installation distance is the normal distance, the load on muscles and joints is reduced.

[0082] The pedal load is the load level applied to the pedal 31, and can be adjusted in five steps from 1 to 5. For example, the load of the pedal 31 is a parameter that can be adjusted by changing the set value of the load resistor of the main body 20. The larger the value indicating the load level, the higher the load applied to muscle parts and joints. By changing the load resistance of the pedal 31 in this way, the load applied to muscle parts and joints can be adjusted.

[0083] The rotation speed corresponds to the rotation speed of the crank 40, and can be adjusted in three stages: high speed, medium speed, and low speed. The faster the rotation speed, the higher the load. The processing system 200, for example, sets a threshold value for the rotation speed for each of high speed, medium speed, and low speed. The processing system 200 compares the rotation speed of the crank with the threshold value, and if the rotation speed of the crank differs from the recommended setting, the output unit 230 described later outputs. In other words, if the rotation speed of the crank 40 is lower than the set rotation speed, the output unit 230 may output an alarm. Alternatively, if the rotation speed of the crank 40 is higher than the set rotation speed, the output unit 230 described later may output an alarm.

[0084] For example, assume that the user data of user U indicates that the user cannot ascend and descend stairs, but can walk. The difficulty level of walking is higher than that of assisted walking, standing, sitting, standing and sitting with assistance, standing, standing with assistance, and stable sitting. Therefore, user U is also capable of assisted walking, standing, sitting, standing and sitting with assistance, standing, standing with assistance, and stable sitting. In this case, the recommended setting calculation unit 211 recommends the recommended setting corresponding to walking. In this case, the installation distance is long, the pedal load is 4, and the rotation speed is high.

[0085] In this way, the recommended setting calculation unit 211 calculates the recommended setting based on the information of the daily living activities that the user U can perform. When the user U can perform a plurality of daily living activities, the recommended setting calculation unit 211 calculates the recommended setting corresponding to the daily living activity with the highest level of difficulty. In other words, the recommended setting calculation unit 211 calculates the recommended setting according to the daily living activity with the highest load among the daily living activities that the user U can perform.

[0086] Furthermore, it is preferable that the processing system 200 prepares a plurality of recommended setting tables according to physical information. For example, it is preferable to classify users into a plurality of groups according to physical information such as height, and set a recommended setting table for each group. In this way, it is possible to obtain appropriate recommended settings according to the physical build of the user U.

[0087] For example, if height is classified into three groups, tall, medium, and short, a recommended setting table for tall height, a recommended setting table for medium height, and a recommended setting table for short height are created. Of course, the number of classifications is not limited to three, but may be two or more. Also, the classification items are not limited to height, and may include other physical information. For example, the user group can be classified based on weight, lower limb length, upper limb length, or trunk length. Classification by multiple classification items is also possible.

[0088] The processing system 200 creates a plurality of groups according to the physical information. The recommended setting calculation unit 211 stores a recommended setting table for each group. The recommended setting calculation unit 211 selects a group to which the user U belongs based on the physical information indicated by the user data. The recommended setting calculation unit 211 then calculates recommended settings using the recommended setting table for the group to which the user U belongs. In this way, it is possible to calculate appropriate recommended settings according to the physical build of the user U.

[0089] The output unit 230 outputs the recommended settings calculated by the recommended setting calculation unit 211. The output unit 230 has a display or the like, and displays the recommended settings to the user U. Alternatively, the output unit 230 may have a speaker for outputting the recommended settings as audio. Furthermore, the output unit 230 may display an alarm. Alternatively, the output unit 230 may output an alarm sound.

[0090] Furthermore, the display of the output unit 230 may display an input screen for user data and muscle site data. For example, a touch panel display may display a keyboard or pull-down menu for inputting numerical values. Alternatively, a question for setting the muscle site and the load amount may be displayed on the display. Alternatively, the output unit 230 may output the question for setting the muscle site and the load amount by voice from a speaker. In this case, the user U or the like may input the muscle site to be trained and the 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.

[0091] The determination unit 240 determines whether the exercise device 100 is operating with the recommended settings calculated by the recommended settings calculation unit 211. If the exercise device 100 is not operating with the recommended settings, the output unit 230 notifies the user U or the like. For example, the output unit 230 may output a warning message or a warning sound. In this way, it is possible to encourage operation with the recommended settings.

[0092] For example, the determination unit 240 may have a sensor capable of detecting the position, angle, shape, and the like of the equipment. Then, the determination unit 240 determines whether the geometric arrangement of various equipment matches the recommended settings based on the detection results of the sensor. For example, the determination unit 240 may detect the presence or absence of equipment such as a contact sensor. Alternatively, the determination unit 240 may detect the presence or absence of equipment, the arrangement of the equipment, the inclination angle, and the like by analyzing an image of the exercise equipment 100 captured by a camera. Then, the determination unit 240 makes a determination by comparing the results detected by the various sensors with the recommended settings.

[0093] The simulator 212 calculates muscle activity using, for example, a computer. The simulator 212 calculates muscle activity using a human body computer model (for example, a human body model such as a human body finite element model). For example, by inputting physique data such as height and lower limb joint length, the simulator 212 creates a human body model having that physique and performs a simulation. The simulator 212 can be used to find parameters for recommended settings. Based on the simulation results in the simulator 212, an upper limit value of the load for the muscle part is set.

[0094] An example of a process for creating a recommended settings table will be described below with reference to Fig. 9. Fig. 9 is a flow chart showing a process for associating recommended settings with daily living activities. By performing the process shown in Fig. 9, it is possible to create the recommended settings table shown in Fig. 8.

[0095] First, the simulator 212 simulates the daily living activities (S101). For example, as the daily living activities, the simulator 212 simulates the movement of ascending and descending stairs. The simulator 212 calculates the maximum value of the load on the muscle parts from the simulation result of the daily living activities. For example, the simulator 212 calculates the maximum value of the load for each muscle part by simulating the movement of ascending and descending stairs. The simulator 212 may also calculate the load (maximum contact force) applied to the joints.

[0096] The simulator 212 then sets an upper limit of the load based on the maximum load applied during the stair climbing and descending movements (S102). A value that does not exceed the maximum load in the daily living movements that the user can handle is set as the upper limit of the load. For example, 40% of the maximum load is set as the upper limit of the load. The upper limit of the load may be set for each muscle part or each joint.

[0097] The simulator 212 judges whether the simulation of all daily living activities has been completed (S103). If the simulator 212 has not completed the simulation of all daily living activities (NO in S103), it changes to the next daily living activity (S104). Then, the simulator 212 simulates the next daily living activity (S101) and sets the upper limit of the load (S102). Thereby, for example, the upper limit of the load is set based on the maximum value of the load in the walking movement. By repeating the above process, the simulator 212 can set the upper limit of the load for the walking movement, the assisted walking, the standing position, etc. That is, the simulator 212 can set the upper limit of the load for each daily living activity.

[0098] When the simulator 212 has finished simulating all the activities of daily living (YES in S103), the simulator 212 performs a simulation of a pedaling exercise (S105). Here, it is preferable that the simulator 212 uses the same simulation model for the simulation of the activities of daily living (step S101) and the simulation of the pedaling exercise (step S105). It is also preferable that the simulation of the pedaling exercise in S105 is performed using the same physical information data as the simulation of the activities of daily living in S101.

[0099] In step S105, the simulator 212 calculates the change in muscle activity of each muscle due to the pedaling motion. The simulator 212 calculates the time change in muscle activity during one rotation time. The simulator 212 calculates the load applied to each muscle part by the pedaling motion. The load applied by the pedaling motion may be calculated for each muscle part. The simulator 212 may also calculate the load applied to the joint (maximum contact force).

[0100] Next, the simulator 212 judges whether or not the simulation for all parameters has been completed (S106). If the simulator 212 has not completed the simulation for all parameters (NO in S106), the parameters of the setting items are changed (S107). Then, the process returns to S105, and the simulator 212 performs a simulation of the pedaling motion. For example, if the installation distance can be adjusted in three stages, the pedal load in five stages, and the rotation speed in three stages, the simulation of the pedaling motion is performed 45 (=3×5×3) times.

[0101] When the simulator 212 has finished simulating all parameters (YES in S106), it determines the parameters to be the recommended settings (S108). The simulator 212 compares the load obtained by the simulation of the leg-rowing exercise with the upper limit value set in S102, and sets the recommended settings so that the load does not exceed the upper limit value. In other words, the parameters of the leg-rowing exercise that have produced a simulation result in which the load does not exceed the upper limit value are set as the recommended settings. The parameters that have produced a simulation result in which the load on each muscle site is equal to or less than the upper limit value are saved as the recommended settings. In this way, it is possible to associate the recommended settings with each daily living activity. Therefore, it is possible to set the recommended setting parameters shown in FIG. 8.

[0102] The processing system 200 calculates the maximum load applied to muscle parts during the user's possible daily living activities by simulation. Then, the processing system 200 determines the upper limit of the load based on the maximum load. In other words, the processing system 200 sets the upper limit of the load so as not to exceed the maximum load applied to muscle parts during daily living activities. This allows the user U to perform pedaling exercise with set parameters suitable for the user U, allowing for effective training. It is possible to prevent the user U from being subjected to an excessive load, and to stably perform safe training.

[0103] Also, it is not necessary to perform simulations for all parameters. For example, the process may end when the recommended settings for each daily living activity are determined. Also, in the above description, one recommended setting is associated with each daily living activity, but multiple recommended settings may be associated with each activity. In this case, the user U or the like can select a more appropriate recommended setting from the multiple recommended settings. Therefore, the user U can perform pedaling exercise with parameters set appropriately for the user U, and therefore the user can train effectively.

[0104] The load obtained by the simulation using the simulator 212 will be described below.

[0105] The change in load when the installation distance is changed will be described using Figs. 10 to 16. Figs. 10 to 16 show the simulation results when the simulation conditions related to the setting items are changed as shown in Figs. 4 to 7. In Fig. 4, the installation distance parameter is changed to normal distance, short distance, and long distance. Note that the normal distance setting shown in Fig. 4 is the standard setting, and unless otherwise specified, the parameters of the standard setting will be used. The standard settings are no installation platform, no pedal inclination, and no inclined platform.

[0106] Furthermore, the simulation results of the load during the standing up and walking out movements are shown as daily living movements. Here, the simulator 212 calculates the maximum contact amount applied to the hip joint, knee joint, and ankle joint. The load during pedaling a normal distance is set to 1.

[0107] The load is higher for the walking motion than for the standing motion. If the installation distance is set to a long distance, the load is higher than for the normal distance. Therefore, if the user U can perform difficult daily living activities, the installation distance can be set to a long distance to increase the load.

[0108] In Fig. 5, a setting stand is provided and the setting distance parameter is changed to normal distance and long distance. In Fig. 6, a pedal inclination is provided and the setting distance parameter is changed to normal distance and long distance. In Fig. 7, a tilted stand is provided and the setting distance parameter is changed to normal distance and long distance. For comparison, Figs. 10 to 16 show the loads for standing up and walking out.

[0109] Figures 10 to 13 are graphs showing the change in load depending on the installation distance. Figures 10 to 12 are graphs showing the maximum contact forces of the hip joint, knee joint, and ankle joint, respectively. Figure 13 is a graph showing the maximum compressive stress of the intervertebral disc. Figure 14 is a graph summarizing the load (maximum contact forces) applied to the right lower limb joints (ankle joint, knee joint, hip joint).

[0110] Fig. 15 is a graph showing the load on the trunk muscles. Fig. 16 is a graph showing the load on the plantar flexor muscles of the stepping foot. Fig. 15 shows the muscle activity of the left and right rectus abdominis and erector spinae. Fig. 16 shows the muscle activity of the soleus and gastrocnemius.

[0111] As shown in Figure 10, by setting the installation distance to a long distance, the load on the hip joint can be increased. Also, even if all inclinations are eliminated and the distance is changed from the normal distance to a short distance, the load on the hip joint increases.

[0112] As shown in Figure 11, by setting the installation distance to a long distance, the load on the knee joint can be increased. However, when there is an installation stand, setting the installation distance to a long distance reduces the load compared to the normal distance.

[0113] As shown in Figure 12, by increasing the installation distance, the load on the ankle joint can be increased. However, when there is an installation stand, the load is greater at a longer distance than at a normal distance.

[0114] As shown in Figure 13, the load on the spine does not change much even if the installation distance is changed. However, when the installation platform is installed, the load is higher at long distances than at normal distances. Also, the load caused by pedaling is about the same as that caused by standing up, and is smaller than that caused by walking.

[0115] As shown in Figure 14, the load on the entire joints of the lower limbs increases as the installation distance becomes longer. The load on the entire joints of the lower limbs is smaller than that in the standing up motion and the walking starting motion.

[0116] As shown in Figure 15, when the installation distance is increased, the muscle activity of the rectus abdominis (abdominal muscles) increases. The muscle activity (load) of the rectus abdominis becomes similar to that of the standing up motion and the walking out motion. The muscle activity of the erector spinae (back muscles) becomes smaller than that of the standing up motion and the walking out motion.

[0117] As shown in Figure 16, when the pedal is tilted, the plantar flexor muscle activity (load) decreases as the pedal distance increases. When the tilt table is present, the muscle activity increases more than when the pedal is set up to a walking position as the pedal distance increases. When the tilt table is not present, the load during pedaling is lower than when the pedal is set up to a standing position and when the pedal is set up to a walking position.

[0118] Using Figs. 17 to 22, the change in load when the geometric arrangement is changed will be described. Figs. 17 to 22 show the results of simulation when the simulation conditions related to the setting items are changed. Here, Figs. 17 to 22 are graphs showing the load when there is an installation platform, pedal inclination, and tilt platform, with respect to the standard setting. Furthermore, Figs. 17 to 22 show the load when the installation distance is long, there is no tilt, there is an installation platform, there is pedal inclination, and there is a tilt platform. For comparison, Figs. 17 to 22 show the load of a standing up motion and a walking starting motion.

[0119] Figures 17 to 22 are graphs showing the change in load due to geometric arrangement. Figures 17 to 19 are graphs showing the maximum contact forces of the hip joint, knee joint, and ankle joint, respectively. Figure 20 is a graph showing the maximum compressive stress of the intervertebral disc. Figure 21 is a graph showing the load on the muscles of the trunk. Figure 22 is a graph showing the load on the plantar flexor muscles of the stepping foot. Figure 21 shows the muscle activity of the left and right rectus abdominis and erector spinae. Figure 22 shows the muscle activity of the soleus and gastrocnemius.

[0120] As shown in Figure 17, when there is a mounting platform, the load (maximum contact force) on the hip joint is large regardless of the mounting distance. Also, the difference due to the geometric arrangement is large. For all parameters, the load on the hip joint is smaller than that for the standing up motion and the walking starting motion.

[0121] As shown in Figure 18, the load (maximum contact force) on the knee joint is about the same when the installation stand is installed at a normal distance and when it is installed at a long distance with no tilt. Also, when the installation distance is long, the difference due to the geometric arrangement is small. Also, for all parameters, the load on the knee joint is smaller than when standing up and starting to walk.

[0122] As shown in Figure 19, when there is an inclined platform, the load (maximum contact force) on the ankle joint is larger. Also, except for the standard setting, the load is larger than that in the standing up motion. For all parameters, the load on the ankle joint is smaller than that in the walking motion.

[0123] As shown in Figure 20, when the device is placed at a normal distance, the load on the spine (maximum compressive stress on the intervertebral disc) increases when the device is placed at a tilted table. When the device is placed at a long distance, the load increases when the device is placed and when the device is placed at a tilted table. The load on the spine is about the same as when the device is placed at a standing position, but is smaller than when the device is placed at a walking position.

[0124] By changing the geometric arrangement of the exercise machine 100 in this way, the load on muscle parts and joints changes. The simulator 212 performs simulations in advance with various arrangements, so that the recommended setting calculation unit 211 can present appropriate recommended settings. In other words, it is possible to extract parameters for setting items that do not cause the load on the pedaling exercise to exceed the load on the daily living activities. The simulator 212 can calculate the load for each joint and each muscle part, so it can present more appropriate recommended settings.

[0125] It is preferable that the recommended setting calculation unit 211 calculates a recommended setting for setting the installation distance from the rotation axis of the pedaling motion to the seat part. Furthermore, it is preferable that the recommended setting calculation unit 211 calculates a recommended setting for setting the load resistance of the pedal 31. This makes it possible to easily adjust the load.

[0126] The processing system 200 may be shared by multiple exercise machines 100. That is, in a rehabilitation center or the like where multiple exercise machines 100 are installed, one computer may be installed as the processing system 200. Then, one computer serving as the processing system 200 can calculate recommended settings for the multiple exercise machines 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 terminal on the user U side. The human body computer model is not limited to a human body finite element model, and other human body models may be used.

[0127] In addition, a part or all of the processes in the above-mentioned processing system 200 etc. 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. The non-transitory computer-readable media includes various types of tangible recording media.
