Description

Technical Field

[0001] This invention belongs to the field of human movement assistance technology, specifically relating to a resistance training method and device based on the same resistance device. Background Technology

[0002] Resistance training, also known as strength training, is a type of exercise that involves working against resistance. Its primary purpose is to train the body's muscles, and it's an indispensable part of daily exercise. Through strength training, muscle strength increases, leading to stronger muscle fibers, which in turn increases bone density and strength, and can reduce the risk of osteoporosis in middle-aged and elderly people. Furthermore, resistance training increases calorie expenditure, helping to control weight. It also offers numerous benefits such as improved coordination, increased muscle strength, pain relief, lower blood pressure, faster metabolism, and improved complexion.

[0003] Many forms of exercise can be combined with resistance training. For example, the most common form of exercise is running. Generally speaking, the more time and effort you invest in running training, the fewer training options you have. However, if you combine resistance training with running training, you can further expand the training options to include a variety of different programs. Users can decide the intensity of resistance training and the body parts that need to be trained according to their own needs.

[0004] Currently, weight training is an important form of resistance training. However, weight training can easily cause injuries to the knees, ankles, spine, and other parts of the body. Furthermore, carrying heavy objects during training can affect the athlete's normal movement, increasing the risk of injury. In addition, the method of weight training must be carefully considered, especially when the weight is heavy. Users generally have to choose to carry heavy objects for extended periods, which can cause damage to the spine, shoulders, and lower back. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this invention proposes a resistance training method based on the same resistance device, the method comprising:

[0006] The user's left and right hip joints are connected to the same resistance device, and the direction of movement of the user's left and right hip joints is continuously detected through the resistance device.

[0007] If the movement direction of one hip joint of the user is detected to be the same as the preset movement direction, the resistance device applies resistance to the user's hip joint on that side until the movement direction of the user's hip joint on that side changes.

[0008] Furthermore, the resistance device continuously detects the direction of movement of the user's left and right hip joints, including:

[0009] Select one hip joint from the user's left and right hip joints, and have the resistance device continuously detect the direction of movement of the selected hip joint;

[0010] The method also includes:

[0011] If the user's hip joint movement direction is opposite to the preset movement direction, the resistance device applies resistance to the user's other hip joint until the user's hip joint movement direction changes.

[0012] Specifically, the resistance device includes a motor, a first slide bar, and a slider. The slider is slidably disposed on the first slide bar. The slider is connected to the user's left hip joint through a first elastic element and to the user's right hip joint through a second elastic element. When the direction of movement of one of the user's left and right hip joints is the same as the preset direction of movement, the slider is driven to slide on the first slide bar through the elastic element connected to that hip joint.

[0013] The resistance applied to impede the movement of the user's hip joint on that side is achieved by the motor in a manner that prevents the slider from sliding.

[0014] Specifically, the sliding direction of the slider on the first slide bar includes a first direction and a second direction, wherein the first direction is opposite to the second direction;

[0015] If the user's left hip joint moves in the same direction as the preset direction, the slider will slide in the first direction on the first slider.

[0016] If the user's right hip joint moves in the same direction as the preset direction, the slider will slide in the second direction on the first slider.

[0017] Furthermore, the resistance that prevents the slider from sliding is determined by the sliding direction and the sliding speed of the slider; the sliding direction and the sliding speed of the slider are obtained by the motor.

[0018] Preferably, the user's left hip joint and right hip joint are directly connected by a third elastic element;

[0019] The method further includes: when the direction of movement of one hip joint of the user's left and right hip joints is the same as the preset direction of movement, applying resistance to the hip joint of that side through the third elastic element to impede the movement of that hip joint.

[0020] Optionally, the preset activity direction includes hip extension or hip flexion.

[0021] The present invention also proposes a resistance training device for implementing the method described above. The device includes a resistance device, which includes a motor, a first slide bar, and a slider. The slider is slidably disposed on the first slide bar. The slider is connected to the user's left hip joint through a first elastic element and to the user's right hip joint through a second elastic element.

[0022] The motor is used to obtain the sliding direction and sliding speed of the slider, and to control the slider to slide on the first slide bar.

[0023] Optionally, the first slide bar includes a screw with threads on its outer side, and the connecting hole between the slider and the first slide bar is provided with threads adapted to the first slide bar;

[0024] The motor is connected to the first end of the first slide bar and is used to control the slider to slide on the first slide bar by driving the first slide bar to rotate. The second end of the first slide bar is fixedly set.

[0025] Optionally, the resistance device further includes a second slide bar, which is arranged parallel to the first slide bar. The motor is slidably mounted on the second slide bar and is fixedly connected to the slider. The sliding of the motor on the second slide bar is synchronized with the sliding of the slider on the first slide bar.

[0026] The present invention has at least the following beneficial effects:

[0027] The method proposed in this invention is based on the human exoskeleton structure and provides a flexible, convenient, and low-risk scientific training method for athletes who need to perform resistance training. It only requires one resistance device, which is relatively lightweight. This method eliminates the need for users to perform resistance training through traditional weight-bearing methods, and will not cause damage to the user's body parts, thus increasing the safety of users performing resistance training.

[0028] Furthermore, the method proposed in this invention can adjust the resistance provided to the user according to the user's own needs and exercise conditions, which can better cooperate with the user in exercise training. At the same time, when the exerciser performs exercises with opposite hip joint movements, such as running, the hip joint on the side with smaller range of motion can provide resistance to the other hip joint.

[0029] Therefore, the present invention provides a resistance training method and device based on a single resistance device. The method proposed in this invention allows users to train without relying on traditional weight-bearing methods, and can apply flexible and controllable resistance to assist users in their training. Moreover, it only requires one resistance device. While providing users with a simple and convenient resistance training method, it greatly reduces the risk of user injury and provides a reliable guarantee for the safety of users in sports training.

[0046] Example 1

[0047] This embodiment proposes a resistance training method based on a single resistance device. This method utilizes the human exoskeleton structure, eliminating the need for traditional weight-bearing methods. The proposed method primarily focuses on resistance training of the user's hip joint reciprocating motion. This method allows for the application of flexible and controllable resistance to assist the user's training. Please refer to [reference needed]. Figure 1 The method includes:

[0048] S100: Connects the user's left and right hip joints to the same resistance device, and continuously detects the direction of movement of the user's left and right hip joints through the resistance device.

[0049] In this embodiment, the user's left and right hip joints are connected to the resistance device via elastic elements.

[0050] S200: If it is detected that the direction of movement of one hip joint of the user's left or right hip joint is the same as the preset direction of movement, the resistance device applies resistance to the hip joint on that side to impede the movement of that hip joint until the direction of movement of that hip joint changes.

[0051] Specifically, the direction of movement used as the detection benchmark can be preset by the user. In this embodiment, the selectable preset directions of movement include the hip flexion direction (i.e., the hip joint angle value changes from large to small) or the hip extension direction (i.e., the hip joint angle value changes from small to large).

[0052] In this embodiment, taking the user's running, race walking and other sports as examples, resistance training is generally achieved by applying resistance when the user lifts their legs. Therefore, in this embodiment, the preset direction of activity is the hip extension direction of the hip joint.

[0053] When a user is running, brisk walking, or performing other similar exercises, and lifts their left leg, the user's left hip joint moves in the direction of hip extension. If the resistance device detects that the user's left hip joint is moving in the same direction as a preset direction, it applies resistance to the user's left hip joint until the direction of movement changes. In this embodiment, the resistance applied to the left hip joint may include, but is not limited to, hip flexion force. When the direction of movement of the left hip joint changes to hip flexion, the resistance device stops applying resistance to the user's left hip joint.

[0054] In general, when a user performs sports such as running or race walking, the movement direction of the left and right legs alternates, that is, when the left leg is raised, the right leg is lowered, and vice versa. Therefore, optionally, when the user performs such sports, step S100 can simply use a resistance device to continuously detect the movement direction of the user's hip joint on either side. If the movement direction of the hip joint on that side is detected to be the same as the preset movement direction, the resistance device applies resistance to the hip joint on that side to impede its movement; if the movement direction of the hip joint on that side is detected to be opposite to the preset movement direction, the resistance device applies resistance to the other hip joint to impede its movement.

[0055] Preferably, see Figure 2 , Figure 4 The resistance device includes a motor, a first slide bar, and a slider. The slider is slidably mounted on the first slide bar. The motor is used to detect the position of the slider on the first slide bar to obtain the direction and distance of the slider's sliding relative to its initial position, and thereby obtain the speed of the slider's sliding. The slider is connected to the user's left hip joint through a first elastic element and to the user's right hip joint through a second elastic element, so that when the direction of movement of one hip joint is the same as the preset direction of movement, the hip joint on that side drives the slider to slide on the first slide bar through the elastic element.

[0056] It should be noted that the sliding direction of the slider on the first slide bar includes a first direction and a second direction. The first direction and the second direction are two different directions extending along the first slide bar, and the first direction is opposite to the second direction. For example, when the user's left leg lifts, the user's left hip joint moves in the same direction as the preset direction, and the left hip joint drives the slider to move in the first direction on the first slide bar through the first elastic element. When the user's right leg lifts, the user's right hip joint moves in the same direction as the preset direction, and the right hip joint drives the slider to move in the second direction on the first slide bar through the second elastic element.

[0057] Thus, when the user's hip joint movement causes the slider to slide on the first slider, the motor can determine which side of the hip joint the user is moving in the same direction as the preset movement by detecting the position of the slider in real time. At the same time, the sliding speed of the slider can be obtained by the correlation between the position of the slider and the time point, and then the angle change of the hip joint on that side when the user is moving can be inferred, that is, the angular velocity of the hip joint on that side.

[0058] The motor is also used to control the sliding of the slider on the first slide bar. The direction of the slider sliding controlled by the motor is either a first direction or a second direction. After obtaining the angular velocity of the hip joint on that side, the motor causes the slider to slide in the opposite direction to the direction in which the hip joint drives the slider to slide. The magnitude of the sliding speed of the slider controlled by the motor is determined based on the angular velocity of the user's hip joint on that side obtained by the motor.

[0059] For example, when the user's left leg is raised, the user's left hip joint moves in the same direction as the preset direction. The left hip joint drives the slider to move in the first direction on the first slide bar through the first elastic element. The motor obtains the angular velocity of the user's left hip joint through the movement of the slider and provides the slider with a force in the second direction. The magnitude of the force is determined based on the angular velocity of the user's left hip joint.

[0060] With the above settings, the method proposed in this invention only requires one motor to detect the direction and angular velocity of the left and right hip joints during the user's movement, and provides appropriate resistance to the user's hip joints based on the detection results to assist the user in resistance training. It is relatively simple and convenient. For example, it provides greater resistance when the user's hip joint movement speed is faster and less resistance when the user's hip joint movement speed is slower. Therefore, this method has the characteristics of being simple, convenient and flexible.

[0061] In this embodiment, the first end of the first elastic element is connected to the slider, and the first end of the second elastic element is also connected to the slider. Based on this, to facilitate the integration of the user's left and right hip joint movements and make the user's left and right hip joint movements more coordinated, please refer to... Figure 3Preferably, a connector can be added to the above solution to connect the second end of the first elastic member and the second end of the second elastic member. The connector may be a linear object such as a thin rope.

[0062] The user's left hip joint is rotatably connected to a first sensor, and the first sensor is connected to a first transmission component. The connection between the first elastic element and the connecting element is slidably disposed on the first transmission component. At the same time, the user's right hip joint is rotatably connected to a second sensor, and the second sensor is connected to a second transmission component. The connection between the second elastic element and the connecting element is slidably disposed on the second transmission component.

[0063] It should be noted that the connection between the first elastic element and the connecting element is slidably disposed on the first transmission element, and the connection between the second elastic element and the connecting element is slidably disposed on the second transmission element, similar to a rope being slidably disposed on a pulley. Taking the first transmission element as an example, when the first transmission element rotates, the length of the first elastic element and the part of the elastic element slidably disposed on the first transmission element will change accordingly. When the length of the part of the first elastic element slidably disposed on the first transmission element decreases, the length of the part of the elastic element slidably disposed on the first transmission element will increase by the corresponding length, and vice versa.

[0064] In this embodiment, the first sensing element drives the first transmission element to rotate in the opposite direction, and the second sensing element drives the second transmission element to rotate in the opposite direction. The first transmission element can drive the first sensing element to rotate in the opposite direction, and the second transmission element can drive the second sensing element to rotate in the opposite direction. Taking the first sensing element and the first transmission element as an example, when the first sensing element rotates in the clockwise direction, it drives the first transmission element to rotate in the counterclockwise direction.

[0065] It should be noted that the connection methods between the first sensing element and the first transmission element, and between the second sensing element and the second transmission element, include, but are not limited to, gear connection, elastic connection, and other connection methods.

[0066] For example, when a user moves the left hip joint, the first sensor rotates in the first clockwise direction. The rotation of the first sensor further drives the first transmission component to rotate in the second clockwise direction. The rotation of the first transmission component changes the length of the first elastic element and the elastic element slidingly disposed in the first transmission component. The first transmission component drives the second transmission component to rotate in the first clockwise direction through the connecting member.

[0067] The rotation of the second transmission component will further drive the second sensing component to rotate in the second clockwise direction. The rotation of the second transmission component will change the length of the second elastic component and the elastic component slidingly disposed on the second transmission component, ultimately achieving the purpose of making the user's right hip joint move in the opposite direction to the left hip joint, so as to increase the coordination of the user's left and right hip joint movements.

[0068] It should be noted that the above-mentioned extension scheme can also be applied to Figure 4 and Figure 5 The provided implementation method.

[0069] Optionally, please refer to again Figure 2 The motor can be mounted on the slider, and the motor can directly acquire information on the direction and angular velocity of the left and right hip joints during the user's movement through its own movement.

[0070] Furthermore, the resistance device also includes a second slide bar, which is arranged parallel to the first slide bar. The motor is fixedly connected to the slider, and the motor is slidably mounted on the second slide bar. When the user's hip joint movement causes the slider to slide on the first slide bar, the motor connected to the slider slides synchronously on the second slide bar. The motor can directly obtain the left and right hip joint movement direction and angular velocity information during the user's movement through its own movement, and based on the obtained information, it provides itself with a suitable force opposite to the sliding direction, which is equivalent to providing resistance for the slider's sliding on the first slide bar, thereby achieving the purpose of providing suitable resistance for the user's hip joint.

[0071] Optionally, please refer to again Figure 4 In one specific embodiment, the first slide rod is a screw rod with threads on the outside. The motor is connected to the first end of the first slide rod, the second end of the first slide rod is fixed, and the connecting hole between the slider and the first slide rod is provided with threads adapted to the first slide rod, so that the slider can slide on the first slide rod in a first direction or a second direction.

[0072] When the user's hip joint movement causes the slider to slide on the first slide bar, the slider will drive the first slide bar to rotate through the screw thread. The motor connected to the first slide bar can obtain information such as the rotation speed, rotation angle, and number of rotations of the first slide bar to obtain information on the direction and angular velocity of the user's left and right hip joint movements during the movement. Based on the obtained information, the motor will cause the first slide bar to rotate in the opposite direction at a corresponding angular velocity to provide resistance to the slider sliding on the first slide bar, thereby achieving the purpose of providing appropriate resistance to the user's hip joint.

[0073] Alternatively, please refer to Figure 5 In this embodiment, no slider is required. The first slide rod is a screw with threads on the outside. The motor is connected to the first end of the first slide rod, and the second end of the first slide rod is fixed. The first elastic element and the second elastic element are connected to the resistance device by being wound together on the first slide rod. When the user's hip joint moves and the elastic element connected to the hip joint drives the first slide rod to rotate, the motor can directly obtain the left and right hip joint movement direction and angular velocity information during the user's movement through its own movement. Based on the obtained information, the first slide rod rotates in the opposite direction with the corresponding angular velocity, thereby achieving the purpose of providing appropriate resistance to the user's hip joint.

[0074] Furthermore, since the rate of change of angular velocity of the hip joint on the leg-lifting side is generally greater than that on the leg-retracting side during activities such as running and race walking, this invention can, in addition to the existing method, apply resistance to the hip joint on the leg-lifting side through the hip joint on the leg-retracting side. Specifically, the method further includes:

[0075] If the direction of movement of one hip joint is the same as the preset direction of movement, the rate of change of the angular velocity of that hip joint is greater than that of the other hip joint. This allows the user's left and right hip joints to be directly connected via a third elastic element. When the direction of movement of one hip joint is the same as the preset direction of movement, the third elastic element applies resistance to that hip joint's movement. This resistance is applied by the other hip joint using the third elastic element as a medium.

[0076] Optionally, the first elastic element, the second elastic element, and the third elastic element include, but are not limited to, latex tape, rubber tape, or silicone tape with a certain degree of elasticity. The first elastic element, the second elastic element, and the third elastic element can be connected to the user's hip joint through structures such as nylon tape or leg loops. The nylon tape or leg loop structure can be formed into a ring and fitted on the outside of the user's hip joint through Velcro, buttons, snap-fit ​​structures, etc., which is also convenient when it is necessary to disconnect the elastic element from the user's hip joint.

[0077] Example 2

[0078] This embodiment proposes a resistance training device. The device connects to the user's left and right hip joints via two elastic elements to detect the direction of movement of the user's left and right hip joints. Based on the detection results, it applies resistance to the hip joint on the affected side, hindering its movement. This resistance training device is used to implement the resistance training method based on the same resistance device proposed in Embodiment 1. This method includes the following steps:

[0079] S100: Connects the user's left and right hip joints to the same resistance device 1, and continuously detects the direction of movement of the user's left and right hip joints through the resistance device 1.

[0080] S200: If it is detected that the direction of movement of one hip joint is the same as the preset direction of movement, the resistance device 1 applies resistance to the hip joint on that side to impede its movement until the direction of movement of the hip joint on that side changes.

[0081] Specifically, the resistance device 1 includes a motor 11, a first slide bar 12, and a slider 13. The slider 13 is slidably disposed on the first slide bar 12. The motor 11 is used to detect the position of the slider 13 on the first slide bar 12 to obtain the direction and distance of the slider 13 sliding relative to the initial position, and thereby obtain the speed of the slider 13 sliding. The slider 13 is connected to the user's left hip joint through the first elastic member 2 and to the user's right hip joint through the second elastic member 3, so that when the direction of movement of one hip joint is the same as the preset direction of movement, the hip joint on that side drives the slider 13 to slide on the first slide bar 12 through the elastic member.

[0082] For example, when the user's left leg is raised, the user's left hip joint moves in the same direction as the preset direction, and the left hip joint drives the slider 13 to move in the first direction on the first slide bar 12 via the first elastic element 2; when the user's right leg is raised, the user's right hip joint moves in the same direction as the preset direction, and the right hip joint drives the slider 13 to move in the second direction on the first slide bar 12 via the second elastic element 3; the first direction and the second direction are opposite.

[0083] Thus, when the user's hip joint movement causes the slider 13 to slide on the first slider 12, the motor 11 can determine which side of the hip joint is in the same direction as the user's preset movement by detecting the position of the slider 13 in real time. At the same time, the sliding speed of the slider 13 can be obtained by the correlation between the position of the slider 13 and the time point, and then the angle change of the hip joint on that side when the user is exercising can be inferred, that is, the angular velocity of the hip joint on that side.

[0084] The motor 11 is also used to control the sliding of the slider 13 on the first slide bar 12. The motor 11 controls the slider 13 to slide in either a first direction or a second direction. After obtaining the angular velocity of the hip joint on that side, the motor 11 causes the slider 13 to slide in the opposite direction to the direction in which the hip joint drives the slider 13 to slide. The magnitude of the sliding speed of the slider 13 controlled by the motor 11 is determined based on the angular velocity of the user's hip joint on that side obtained by the motor 11.

[0085] For example, when the user's left leg is raised, the user's left hip joint moves in the same direction as the preset direction. The left hip joint drives the slider 13 to move in the first direction on the first slide bar 12 through the first elastic element 2. The motor 11 obtains the angular velocity of the user's left hip joint through the movement of the slider 13 and provides a force to the slider 13 in the second direction. The magnitude of the force is determined based on the angular velocity of the user's left hip joint.

[0086] With the above configuration, the resistance training device proposed in this invention only requires one motor to detect the direction and angular velocity of the left and right hip joints during the user's exercise. Based on the detection results, it provides appropriate resistance to the user's hip joints to assist the user in resistance training. It is relatively simple and lightweight. Therefore, the resistance training device proposed in this embodiment has the advantages of simple structure, convenient operation, and easy portability.

[0087] Please refer to this again. Figure 2 In one specific embodiment, the motor 11 can be mounted on the slider 13, and the motor 11 can directly acquire the left and right hip joint movement direction and angular velocity information during the user's movement through its own movement.

[0088] Furthermore, the resistance device 1 also includes a second slide bar 14, which is arranged parallel to the first slide bar 12. The motor 11 is fixedly connected to the slider 13, and the motor 11 is slidably mounted on the second slide bar 14. When the user's hip joint movement causes the slider 13 to slide on the first slide bar 12, the motor 11 connected to the slider 13 slides synchronously on the second slide bar 14. The motor 11 can directly obtain the left and right hip joint movement direction and angular velocity information during the user's movement through its own movement, and provide itself with a suitable force opposite to the sliding direction based on the obtained information. This is equivalent to providing resistance for the slider 13 to slide on the first slide bar 12, thereby achieving the purpose of providing suitable resistance for the user's hip joint.

[0089] In this embodiment, the first end of the first elastic element 2 is connected to the slider, and the first end of the second elastic element 3 is also connected to the slider. Based on this, to facilitate the integration of the user's left and right hip joint movements and make the user's left and right hip joint movements more coordinated, please refer to... Figure 3 Preferably, a connector 4 can be added to the above scheme to connect the second end of the first elastic member 2 and the second end of the second elastic member 3. The connector 4 can be a linear object such as a thin rope.

[0090] The user's left hip joint is rotatably connected to the first sensor 21, and the first sensor 21 is connected to the first transmission component 22. The connection between the first elastic element 2 and the connecting element 4 is slidably disposed on the first transmission component 22. At the same time, the user's right hip joint is rotatably connected to the second sensor 31, and the second sensor 31 is connected to the second transmission component 32. The connection between the second elastic element 3 and the connecting element 4 is slidably disposed on the second transmission component 32.

[0091] It should be noted that the connection between the first elastic element 2 and the connecting element 4 is slidably disposed on the first transmission element 22, and the connection between the second elastic element 3 and the connecting element 4 is slidably disposed on the second transmission element 32, similar to a rope being slidably disposed on a pulley. Taking the first transmission element 22 as an example, when the first transmission element 22 rotates, the length of the first elastic element 2 and the part of the elastic element slidably disposed on the first transmission element 22 will change accordingly. When the length of the part of the first elastic element 2 slidably disposed on the first transmission element 22 decreases, the length of the part of the elastic element slidably disposed on the first transmission element 22 will increase by the corresponding length, and vice versa.

[0092] In this embodiment, the first sensing element 21 drives the first transmission element 22 to rotate in the opposite direction, and the second sensing element 31 drives the second transmission element 32 to rotate in the opposite direction. The first transmission element 22 can drive the first sensing element 21 to rotate in the opposite direction, and the second transmission element 32 can drive the second sensing element 31 to rotate in the opposite direction. Taking the first sensing element 21 and the first transmission element 22 as an example, when the first sensing element 21 rotates in the clockwise direction, it drives the first transmission element 22 to rotate in the counterclockwise direction.

[0093] It should be noted that the connection methods between the first sensing element 21 and the first transmission element 22, and between the second sensing element 31 and the second transmission element 32, include, but are not limited to, gear connection, elastic connection, and other connection methods.

[0094] For example, when a user moves the left hip joint, the first sensor 21 is rotated in the first clockwise direction. The rotation of the first sensor 21 will further drive the first transmission member 22 to rotate in the second clockwise direction. The rotation of the first transmission member 22 will change the length of the first elastic member 2 and the part of the elastic member that is slidably disposed in the first transmission member 22. The first transmission member 22 drives the second transmission member 32 to rotate in the first clockwise direction through the connector 4.

[0095] The rotation of the second transmission component 32 will further drive the second sensing component 31 to rotate in the second clockwise direction, and the rotation of the second transmission component 32 will change the length of the second elastic component 3 and the part of the elastic component that is slidably disposed on the second transmission component 32, ultimately achieving the purpose of making the user's right hip joint move in the opposite direction to the left hip joint, so as to increase the coordination of the user's left and right hip joint movements.

[0096] It should be noted that the above-mentioned extended solutions can also be applied to the following text. Figure 4 and Figure 5 The provided implementation method.

[0097] Optionally, please refer to again Figure 4In one specific embodiment, the first slide rod 12 is a screw rod with threads on the outside. The motor 11 is connected to the first end of the first slide rod 12, the second end of the first slide rod 12 is fixed, and the connecting hole of the slider 13 and the first slide rod 12 is provided with threads adapted to the first slide rod 12, so that the slider 13 can slide on the first slide rod 12 in a first direction or a second direction.

[0098] When the user's hip joint movement causes the slider 13 to slide on the first slide rod 12, the slider 13 will drive the first slide rod 12 to rotate through the thread. The motor 11 connected to the first slide rod 12 can obtain information such as the rotation speed, rotation angle, and number of rotations of the first slide rod 12 to obtain information on the direction and angular velocity of the user's left and right hip joint movements during the movement. Based on the obtained information, the first slide rod 12 is rotated in the opposite direction at a corresponding angular velocity to provide resistance to the sliding of the slider 13 on the first slide rod 12, thereby achieving the purpose of providing appropriate resistance to the user's hip joint.

[0099] Alternatively, please refer to Figure 5 In this embodiment, the slider 13 is not required. The first slide rod 12 is a screw with threads on the outside. The motor 11 is connected to the first end of the first slide rod 12, and the second end of the first slide rod 12 is fixed. The first elastic element 2 and the second elastic element 3 are connected to the resistance device 1 by being wound together on the first slide rod 12. When the user's hip joint moves and the elastic element connected to the hip joint drives the first slide rod 12 to rotate, the motor 11 can directly obtain the left and right hip joint movement direction and angular velocity information during the user's movement through its own movement, and based on the obtained information, make the first slide rod 12 rotate in the opposite direction with the corresponding angular velocity, thereby achieving the purpose of providing appropriate resistance to the user's hip joint.

[0100] In this embodiment, to facilitate the user wearing the resistance device 1 during exercise, the resistance device 1 further includes a housing 15. The motor 11, slider 13, first slide rod 12, and second slide rod 14 are all disposed inside the housing 15. At least one end of the first slide rod 12 is fixed to the inner side of the housing 15, and both ends of the second slide rod 14 are respectively fixed to opposite sides of the housing 15. The ends of the first elastic element 2 and the second elastic element 3 connected to the user's hip joint protrude from the housing 15, and the two ends of the connector 4 connected to the first elastic element 2 and the second elastic element 3 protrude from the housing 15. If the resistance device 1 adopts... Figure 4 or Figure 5 The structure shown allows the motor 11 to be fixed to the opposite surfaces of the fixing ends of the first slide rod 12 and the second slide rod 14.

[0101] In summary, this invention provides a resistance training method and device based on a single resistance device. The method proposed in this invention allows users to train without relying on traditional weight-bearing methods, and can apply flexible and controllable resistance to assist users in their training. Moreover, it only requires one resistance device. While providing users with a simple and convenient resistance training method, it greatly reduces the risk of user injury and provides a reliable guarantee for the safety of users in sports training.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
