The display unit 50 displays information related to the load on the liquid crystal screen based on the output of the calculation unit 60.

With reference to FIG. 4, the order of the exercise | movement which flexes and extends the knee 416 (henceforth "knee bending extension exercise | movement") which a user performs using the exercise assistance apparatus 1 is demonstrated.
(Operation 1) The user inserts the toe 414 into the arrangement space S and touches the shin 411 against the shin contact surface 33.
(Operation 2) The user grasps the grip portion 40 (see FIG. 4A).
(Operation 3) The user bends the hip joint and the knee joint (see FIG. 4B). At this time, the above-described change in the tibia angle DA is regulated by the shin contact surface 33. At this time, as shown in FIG. 5, the toe 414 is located in front of the knee 416.
(Operation 4) The user extends the hip joint and the knee joint.
(Operation 5) (Operation 3) and (Operation 4) are repeated a number of times according to the user's preference and purpose.

With reference to FIG. 3, the calculation process of the calculating part 60 in a knee flexion and extension exercise | movement is demonstrated.
The calculation unit 60 starts calculation processing based on the touch panel operation of the display unit 50.
The calculation unit 60 calculates a load applied to the right foot rest 20R (hereinafter, “right foot load GR”) in accordance with a signal from each load sensor 72. Specifically, signals from the load sensors 72 are added, and the right foot load GR is calculated based on the added value.

  The computing unit 60 computes a load (hereinafter, “left foot load GL”) applied to the left foot rest 20L in accordance with a signal from each load sensor 74. Specifically, the signals from the load sensors 74 are added, and the left foot load GL is calculated based on the added value.

  The calculation unit 60 calculates a ratio of the right foot load GR (hereinafter, “right foot ratio RR”) and a ratio of the left foot load GL (hereinafter, “left foot ratio RL”) based on the right foot load GR. The right foot ratio RR is calculated as the ratio of the right foot load GR to the sum of the right foot load GR and the left foot load GL (hereinafter, “total load GS”). The left foot ratio RL is calculated as the ratio of the left foot load GL to the total load GS. The calculation unit 60 outputs the calculated right foot ratio RR and left foot ratio RL to the display unit 50.

  As shown in FIG. 6, the display unit 50 displays a graph 51 on the liquid crystal screen. The display unit 50 displays a load bar 52 indicating the right foot ratio RR and a load bar 53 indicating the left foot ratio RL on the graph 51. The load bar 52 corresponds to “information based on the foot load” and “information based on the right foot load”. The load bar 53 corresponds to “information based on the foot load” and “information based on the left foot load”.

  The calculation unit 60 determines that (operation 3) and (operation 4) of the knee flexion / extension motion have been performed once from the changes in the right foot load GR and the left foot load GL. That is, the load detection unit 70 corresponds to an “motion detection unit”. In the knee flexion and extension exercise, the load applied to the grip portion 40 is larger in the case of (Action 3) than in the case of (Action 4). For this reason, the right foot load GR and the left foot load GL are maximized in (action 4) of the knee flexion and extension exercise, and are minimized in (operation 3). For this reason, the calculation unit 60 has the right foot load GR and the left foot load GL smaller than the first threshold corresponding to (Action 4), and smaller than the second threshold smaller than the first threshold corresponding to (Action 3). When it becomes smaller and larger than the first threshold value, it is determined that the knee flexion and extension exercise has been performed once.

  When the calculation unit 60 determines that (action 3) and (action 4) of the knee flexion / extension movement have been performed once, based on the right foot ratio RR and the left foot ratio RL, the calculation unit 60 sets the target value (hereinafter referred to as the right foot ratio RR). "Right foot target value TR") and a left foot ratio RL target value (hereinafter, "left foot target value TL") are calculated.

  The right foot target value TR and the left foot target value TL are calculated as values that bring the right foot ratio RR and the left foot ratio RL closer to 50% when there is a difference between the right foot ratio RR and the left foot ratio RL. The right foot target value TR and the left foot target value TL are calculated by assuming that the right foot target value TR and the left foot target value TL are both 50% when both the right foot ratio RR and the left foot ratio RL are 50%.

  The calculation unit 60 outputs the right foot ratio RR, the left foot ratio RL, the right foot target value TR, and the left foot target value TL to the display unit 50. The display unit 50 displays the right foot ratio RR, the left foot ratio RL, the right foot target value TR, and the left foot target value TL on the liquid crystal screen.

  As shown in FIG. 7, the display unit 50 displays the target line 54 indicating the right foot target value TR in association with the load bar 52 of the right foot ratio RR, and displays the target line 55 indicating the left foot target value TL as the left foot ratio RL. Are displayed in association with the load bar 53. The target line 54 corresponds to “information based on the foot load” and “information based on the right foot load”. It corresponds to the target line 55, “information based on the foot load” and “information based on the left foot load”.

The operation of the exercise assistance device 1 will be described.
The knee flexion / extension motion in a state where the toe 414 is located at the same position or rearward as the knee 416 in the depth direction has a large load on the knee joint. For this reason, muscle training efficiency can be improved. On the other hand, for example, it is difficult for a user who has pain in the knee 416 to perform a knee flexion and extension exercise with a heavy load on the knee joint. Therefore, for a user who has pain in the knee 416, the number of exercises and continuity can be improved by the knee flexion and extension exercise with a smaller load on the knee joint. For this reason, training efficiency increases when the load on the knee joint is small.

  In the exercise assisting apparatus 1, an arrangement space S is formed between the shin contact surface 33 and the footrest surface 21 of the footrest portion 20. The lower end portion 35 of the shin contact surface 33 is located above the height of the external fruit of a general user. The shin distance LA is smaller than the foot distance LB. For this reason, the user can form a state in which the front portion of the foot is disposed forward of the shin contact surface 33 by inserting the toe 414 into the placement space S. For this reason, the toe 414 can perform the knee flexion and extension exercise in a state where the toe 414 is positioned in front of the knee 416. For this reason, compared with the case where the toe 414 is the same as the knee 416 or located behind the knee 416, the load of the knee flexion and extension movement can be reduced.

  The exercise assisting apparatus 1 has an advantageous effect as compared with the conventional exercise assisting apparatus 300 shown in FIG. The user puts the soles of the footrests 310 and performs the knee flexion and extension exercise with the knees 416 applied to the vertical boards 320. At this time, the patella is pressed against the vertical board 320. For this reason, the movement of the patella is inhibited by the vertical board 320. For this reason, the position of the patella deviates from an appropriate position with respect to the femur and tibia. For this reason, the function which suppresses the movement to the front of a femur falls. For this reason, in the user who has a pain in the knee 416, the knee 416 is likely to be painful. Further, since the patella is pressed by the vertical board 320, the load between the femur and the patella is increased. For this reason, pain is likely to occur in a user whose cartilage between the femur and the patella is deformed. For this reason, it becomes difficult to use the exercise assisting apparatus 300.

  In the exercise assisting apparatus 1, when the shin 411 contacts the shin abutment surface 33 in the knee flexion and extension exercise, the knee 416 does not contact the shin abutment surface 33. For this reason, the patella cannot be pressed against the shin contact surface 33. For this reason, the freedom of movement of the tibia and femur is not suppressed on the back side of the patella. For this reason, movement of the patella and femur is not hindered. For this reason, it is difficult for a user who has pain in the knee 416 to cause pain in the knee 416. In addition, pain is less likely to occur in a user whose cartilage between the femur and the patella is deformed. For this reason, it becomes easy to use the exercise assistance apparatus 1. In addition, since the exercise assisting apparatus 1 includes the elastic member 32, pain is less likely to occur near the knee 416.

  For example, a user who has pain in one of the right knee 416 and the left knee 416 tends to apply a load to the knee 416 that is not painful in knee flexion and extension exercise. For this reason, the training efficiency of the right leg and the left leg in the knee flexion and extension exercises is different. The display unit 50 displays a load bar 52 indicating the right foot ratio RR and a load bar 53 indicating the left foot ratio RL on the graph 51. Therefore, even for a user who has pain in one of the right knee 416 and the left knee 416, the right lower limb and the left lower limb can be trained in a balanced manner.

The exercise assistance device 1 has the following effects.
(1) The exercise assisting device 1 has a shin contact surface 33. The shin contact surface 33 is located above the footrest portion 20, and an arrangement space S is formed between the shinrest surface 33 and the footrest portion 20. For this reason, the user can perform the knee flexion and extension exercise with the toe 414 positioned in front of the knee 416 by arranging the foot in the arrangement space S. For this reason, the load on the knee joint in the knee flexion and extension exercise can be reduced.

  (2) The exercise assisting device 1 has a shin contact surface 33 that is inclined with respect to the footrest surface 21. For this reason, it is possible to perform knee flexion / extension exercise with the position of the lower leg fixed. For this reason, it is possible to perform knee flexion and extension exercise with the user's center of gravity closer to the rear. For this reason, the shear force of the knee 416 can be reduced. For this reason, the training effect of hamstrings including the quadriceps can be enhanced.

  (3) The upper end 34 of the shin contact surface 33 is located below the lower end of the general user's patella. For this reason, the shin contact surface 33 does not contact the knee 416 during the knee flexion and extension exercise. That is, the shin contact surface 33 does not hold the patella. For this reason, the degree of freedom of the knee joint during the knee flexion / extension exercise can be increased as compared with a virtual exercise assisting device in which the shin contact surface 33 contacts the knee 416 during the knee flexion / extension exercise. For this reason, it can suppress that a knee joint hurts at the time of knee flexion and extension exercise.

(4) The exercise assisting apparatus 1 has a grip portion 40. For this reason, the user can perform the knee flexion and extension motion stably by gripping the grip portion 40.
(5) The holding part support part 13 has the adjustment part 13B. For this reason, the height position of the holding | grip part 40 can be adjusted according to a user's physique.

  (6) The display unit 50 displays the load bars 52 and 53. For this reason, the user can grasp the right foot load and the left foot load during knee flexion and extension exercise. For this reason, the user can easily change the load balance between the right foot and the left foot to an appropriate one.

  (7) The display unit 50 displays the target line 54 as a target value for the right foot ratio RR. The display unit 50 displays a target line 55 as a target value for the left foot ratio RL. For this reason, the user can easily grasp an appropriate load balance between the right foot and the left foot.

(Second Embodiment)
The exercise assistance device 1 of the present embodiment has a different configuration in the following part compared to the exercise assistance device 1 of the first embodiment, and has the same configuration in the other parts. That is, the exercise assisting apparatus 1 includes a footrest portion 120 having a bag portion 141 instead of the footrest portion 20.

The footrest surface 121 has a toe placement surface 122 and a heel placement surface 123.
The heel arrangement portion 130 constitutes the heel arrangement surface 123. The right heel arrangement portion 130 and the left heel arrangement portion 130 are independent of each other.

  The airbag 140 has two bag portions 141 and a communication portion 142. One of the two bag portions 141 constitutes the toe placement surface 122 of the right footrest portion 120R. The other of the two bag parts 141 constitutes the toe arrangement surface 122 of the left footrest part 120L. The communication part 142 communicates one of the bag parts 141 and the other of the bag parts 141. For this reason, air can move between the two bag parts 141. The airbag 140 corresponds to a “viscoelastic body”.

  The four load sensors 72 are arranged at each of the four corners of the heel arrangement part 130 of the right foot rest part 120R. The four load sensors 74 are arranged at each of the four corners of the heel arrangement part 130 of the left footrest part 120L.

  As shown in FIG. 18, the rotating shaft 251 extends in the width direction. The rotating shaft 251 is located behind the arrangement space S in the depth direction. The rotation shaft 251 passes through the rotation unit 252 and the support unit 253. The rotating part 252 and the rotating shaft 251 are fixed to each other. For this reason, as FIG. 17 shows, the rotation part 252 and the rotating shaft 251 rotate with respect to the support part 253 based on the load from a user's leg | foot. For this reason, the footrests 220R and 220L rotate around the rotation shaft 251. That is, the footrests 220R and 220L are inclined in the depth direction. The rotation shaft 251 is located at a position corresponding to the ankle when the user places his / her foot on the footrest surface 221. For this reason, the footrest surface 221 is inclined around the portion where the ankle is lowered.

With reference to FIG. 3, the calculation process of the squat frequency | count of the calculating part 60 in squat exercise | movement is demonstrated.

  The load display unit 56 displays a load bar 52 indicating the right foot ratio RR, a load bar 53 indicating the left foot ratio RL, a target line 54 indicating the right foot target value TR, and a target line 55 indicating the left foot target value TL. The target line 54 is displayed in association with the load bar 52 having the right foot ratio RR. The target line 55 is displayed in association with the load bar 53 having the left foot ratio RL. The teaching display unit 57 displays teaching information. The number display unit 58 displays the number of squats.

The operation of the exercise assistance device 1 will be described.
The exercise assisting apparatus 1 has an inclination mechanism 250. For this reason, when the user performs the knee flexion and extension exercise using the exercise assisting device 1, the footrest portion 220 is inclined due to the change in the load position of the user's foot. For this reason, various stimuli can be given to the user.

  The rotation shaft 251 of the tilt mechanism 250 extends in the width direction of the footrests 220R and 220L. For this reason, the footrest portion 220 is inclined upward and downward by the inclination mechanism 250 in the front and rear directions. For this reason, for example, by operating in a state where the front is inclined downward from the rear, the training effect of the plantar flexor muscles can be improved. Further, by performing the operation with the front inclined upward from the rear, the training effect of the dorsiflexor muscle group can be improved. For this reason, the exercise assistance apparatus 1 can make the user select and perform training suitable for various purposes. Further, during normal walking, the soles of the soles are inclined upward and downward at the front and rear. For this reason, the exercise assistance apparatus 1 can make the user perform an operation similar to walking. For this reason, the exercise assistance apparatus 1 can make a user perform the training which trains the muscle for a walk suitably.

  The exercise assisting apparatus 1 has a moving mechanism 240. For this reason, when the user performs the knee flexion and extension exercise using the exercise assisting device 1, the horizontal position of the footrest portion 220 moves in the depth direction due to a change in the load position of the user's foot. For this reason, the exercise | movement which moves a leg | foot to a depth direction can be performed. For this reason, various stimuli can be given to the user.

  The moving mechanism 240 moves the footrests 220R and 220L forward and backward. For this reason, the user can enjoy a rhythmical operation of moving forward and backward while performing, for example, a squat exercise. Also, the plantar flexor muscles are trained when the soles move forward. The dorsiflexor muscles are trained when the soles move backwards. For this reason, the exercise assistance apparatus 1 can make the user select and perform training suitable for various purposes.

  The moving mechanism 240 moves the footrests 220R and 220L forward and upward, and backward and downward. For this reason, the user can perform a squat exercise with a feeling like a swing. For this reason, the user can enjoy a rhythmical operation.

  Further, the guide groove 243 is inclined so as to go upward as it goes forward. For this reason, when the sole is moved forward by the moving mechanism 240, the sole is moved upward, so that the thigh can be effectively trained. Further, since the guide groove 243 is inclined, the balance of the user is easily lost. For this reason, the user's sense of balance and the muscles related to balance can be effectively trained.

  For example, when only the right foot target value TR and the left foot target value TL are displayed on the display unit 50, the user himself considers how to change the operation to achieve the right foot target value TR and the left foot target value TL. There is a need. For this reason, it is difficult for a user who is not familiar with the exercise assisting apparatus 1 to determine what operation should be performed.

  The exercise assisting apparatus 1 displays teaching information for explaining a user's operation for achieving the right foot target value TR and the left foot target value TL. For this reason, the user can easily grasp how to change the operation. Further, when the right foot target value TR and the left foot target value TL are displayed, the user tends to be caught by the target. The exercise assisting apparatus 1 displays teaching information. For this reason, there is little possibility that proper exercise is hindered.

The exercise assisting apparatus 1 has the following effects in addition to the effects (1) to (7) of the first embodiment.
(16) The exercise assisting apparatus 1 includes a moving mechanism 240 and an inclination mechanism 250. For this reason, the user can perform the exercise | movement which moves a sole or inclines a sole, when performing the knee flexion and extension exercise | movement using the exercise assistance apparatus 1. FIG. For this reason, various stimuli can be given to the user.

  (17) The rotation shaft 251 of the tilt mechanism 250 extends in the width direction of the footrests 220R and 220L. For this reason, the exercise assistance apparatus 1 can make the user select and perform training suitable for various purposes.

  (18) The moving mechanism 240 moves the footrests 220R and 220L forward and backward. For this reason, the user can enjoy a rhythmical operation of moving forward and backward while performing, for example, a squat exercise.

  (19) The moving mechanism 240 moves the footrests 220R and 220L forward and upward, and backward and downward. For this reason, the user can perform a squat exercise with a feeling like a swing.

(20) The exercise assisting apparatus 1 displays teaching information. For this reason, the user can easily grasp how to change the operation.
(21) The user's load increases as the knee 416 bends during knee flexion and extension exercise. The exercise assisting device 1 is disposed at a portion where the rotation shaft 251 corresponds to the ankle. For this reason, when the footrest surface 221 is inclined, the user's knee 416 is not easily bent. For this reason, it is difficult for the upper part of the tibia to tilt forward. For this reason, when the knee flexion / extension exercise is performed, an increase or decrease in the exercise load is suppressed.

(Other embodiments)
This exercise assistance device includes embodiments other than the above-described embodiments. Hereinafter, the modification of each said embodiment as other embodiment of this exercise assistance apparatus is shown.

  -The exercise assistance apparatus 1 of 6th Embodiment displays teaching information on the teaching display part 57 of the display part 50 as an image. However, the configuration of the exercise assisting device 1 is not limited to this. For example, the exercise assisting apparatus 1 according to the modified example includes a speaker and displays teaching information as audio information. When the right foot target value TR is larger than the current right foot ratio RR, the arithmetic unit 60 of this modification selects voice information “Please put your weight on the right” as teaching information. When the left foot target value TL is larger than the current left foot ratio RL, the calculation unit 60 selects audio information “Please put your weight on the left” as teaching information. The calculation unit 60 outputs a signal generated based on the selected teaching information to the speaker.

  In the tilt mechanism 250 of the sixth embodiment, the rotation shaft 251 extends in the width direction. However, the configuration of the tilt mechanism 250 is not limited to this. For example, in the tilt mechanism 250 of the modified example, the rotation shaft 251 extends in the depth direction. The tilt mechanism 250 tilts rightward and leftward due to a change in the load position on the sole.

  -The inclination mechanism 250 of 6th Embodiment rotates with the rotating shaft 251. FIG. However, the configuration of the tilt mechanism 250 is not limited to this. For example, instead of the rotating shaft 251, a hinge, a bearing, a link mechanism, or the like can be employed. In short, any tilting mechanism 250 can be adopted as long as the footrests 220R and 220L are tilted by a load from the sole of the user.

  In the tilting mechanism 250 of the sixth embodiment, the right foot rest portion 220R and the left foot rest portion 220L operate separately. However, the configuration of the tilt mechanism 250 is not limited to this. For example, the modified tilt mechanism 250 operates the right foot rest 220R and the left foot rest 220L integrally. Further, the tilt mechanism 250 of the further modified example tilts the rear of the left footrest 220L upward when the front of the right footrest 220R tilts downward, and tilts the left foot when the rear of the right footrest 220R tilts upward. The front of the placing portion 220L is inclined downward.

  -A stopper can also be added to the inclination mechanism 250 of 6th Embodiment. The stopper switches between a state in which the footrest portions 220R and 220L can be tilted by the tilt mechanism 250 and a state in which the footrest portions 220R and 220L cannot be tilted by the tilt mechanism 250. The stopper can employ a configuration in which a user manually inserts a detent member as a stopper into the tilt mechanism 250. Further, it is possible to employ a configuration in which an operation unit connected to a stopper is disposed in the gripping unit 40 and the position of the rotation preventing member is switched by operation of the operation unit.

  -The moving mechanism 240 of 6th Embodiment changes the position of the depth direction as a horizontal position of the footrest parts 220R and 220L. However, the configuration of the moving mechanism 240 is not limited to this. For example, the moving mechanism 240 according to the modified example changes the position in the horizontal direction as the position in the width direction of the footrests 220R and 220L. The guide groove 243 of this modification extends along the width direction.

  -The moving mechanism 240 of 6th Embodiment moves the footrest parts 220R and 220L along the depth direction. However, the configuration of the moving mechanism 240 is not limited to this. For example, the moving mechanism 240 of the modified example shown in FIG. 21 moves outward in the width direction as the footrest portions 220R and 220L move forward. During walking, when the sole moves forward, the sole moves forward and outward. For this reason, the exercise assistance apparatus 1 of this modification can make a user perform training similar to walking.

The exercise assisting apparatus 1 displays the comparison result received from the server on the display unit 50. As a comparison result, for example, a difference in information based on the foot load calculated by the exercise assisting device 1 with respect to an average value of information based on the foot load transmitted by the plurality of exercise assisting devices 1 may be mentioned. The information based on the foot load includes, for example, the right foot load GR, the left foot load GL, and the pedaling force F in the third embodiment.

  -The following structures can also be added to the exercise assistance apparatus 1 of each embodiment. That is, the exercise assisting apparatus 1 creates a training menu from the right foot load GR, the left foot load GL, and the stepping force F in the third embodiment.

The training menu includes the number and speed of knee flexion and extension exercises. As guidance displayed on the display unit 50, sound, light, images, and the like can be employed. Sound, light, images, etc. can be displayed for each knee flexion / extension exercise, or the display content can be changed. In addition, the display or the display content can be changed for each of a plurality of movement periods in one knee flexion / extension exercise. Further, when adopting a modified example in which the heart rate is measured, the guidance for displaying the speed of knee flexion and extension exercise is changed so that the heart rate does not exceed a predetermined heart rate.

  -In the training menu of the above modification, a training menu for standing on one foot can be adopted. In this training menu, for example, when a user who wants to train the right lower limb has performed knee flexion and extension exercise a predetermined number of times (for example, 10 times) or more, the calculation unit 60 sets a target value TR that increases the right foot ratio RR. To do. Then, every time the knee flexion / extension exercise reaches a predetermined number of times, the target value TR at which the right foot ratio RR becomes larger is increased.

  -In the training menu of the said modification, the training menu for walking can also be employ | adopted. In this training menu, each time the knee flexion / extension exercise is performed, the calculation unit 60 sets the target values TR and TL so that the magnitude relationship between the right foot ratio RR and the left foot ratio RL is reversed. That is, the state where the target value TR of the right foot ratio RR is larger than the target value TL of the left foot ratio RL and the state where the target value TL of the left foot ratio RL is larger than the target value TR of the right foot ratio RR are alternately changed. For this reason, the user can perform training similar to walking in which the right foot and the left foot are operated alternately.

  The exercise assistance device 1 of each embodiment has a touch panel function on the display unit 50. However, the configuration of the exercise assisting device 1 is not limited to this. For example, the exercise assisting apparatus 1 according to the modified example does not have a touch panel function on the display unit 50. In this case, an operation unit can be provided separately from the display unit 50.

  The exercise assistance device 1 of each embodiment includes a display unit 50, a calculation unit 60, and a load detection unit 70. However, the configuration of the exercise assisting device 1 is not limited to this. For example, the exercise assisting apparatus 1 according to the modification omits the display unit 50, the calculation unit 60, and the load detection unit 70.

  -The load detection part 70 of each embodiment is arrange | positioned between the support stand 11 and the footrest part 20. As shown in FIG. However, the structure of the load detection part 70 is not restricted to this. For example, the modified load detection unit 70 is disposed on the shin contact surface 33. The load applied to the right shin contact surface 33 correlates with the right foot load GR. The load applied to the left shin contact surface 33 correlates with the left foot load GL. For this reason, the calculating part 60 can calculate the right foot load GR and the left foot load GL based on the outputs of the load sensors 72 and 74. In short, as long as the right foot load GR and the left foot load GL can be calculated, the position of the load detection unit 70 can be changed to any position.

  The exercise assistance device 1 of each embodiment counts the number of knee flexion and extension exercises based on changes in the right foot load GR and the left foot load GL. However, the configuration of the exercise assisting device 1 is not limited to this. For example, the exercise assisting apparatus 1 according to the modified example counts the number of knee flexion and extension exercises based on a change in the load center position CA. The load center position CA is located at the foremost and inner side in (operation 4) of the knee flexion and extension movement, and is located at the most rearward and outer side in (operation 3). For this reason, the calculation part 60 of this modification determines that the knee flexion and extension movement was performed once as follows. That is, the load center position CA moves forward from the first position corresponding to (Action 4), moves backward from the second position behind the first position corresponding to (Action 3), and When moving backward from the first position and forward from the second position, it is determined that the knee flexion and extension movement has been performed once. Further, the exercise assisting apparatus 1 according to a further modification determines that the knee flexion / extension exercise has been performed once as follows. That is, the load center position CA moves to the inside of the first position corresponding to (Action 4), moves to the outside of the second position outside the first position corresponding to (Action 3), and When moving to the outside of the first position and the inside of the second position, it is determined that the knee flexion and extension movement has been performed once.

  The exercise assistance device 1 of each embodiment counts the number of knee flexion and extension exercises based on changes in the right foot load GR and the left foot load GL based on the load detection unit 70. However, the configuration of the exercise assisting device 1 is not limited to this. For example, the exercise assisting apparatus 1 according to the modification includes a contact detection unit. A contact detection part is attached to the intermediate part of the height direction of the holding part support part 13, for example. For example, a strain sensor is employed as the contact detection unit. The user brings the abdomen into contact with the contact detection unit in the knee flexion and extension exercise (operation 4). The contact detection unit outputs an output corresponding to a load due to contact with the abdomen to the calculation unit 60. The calculation unit 60 determines that the knee flexion / extension exercise has been performed once every time the output from the contact detection unit becomes larger than a predetermined value. Note that the contact detection unit of this modification corresponds to an “operation detection unit”.

  Further, the exercise assisting apparatus 1 of a further modification adds a load change detection unit to the grip unit 40 or the grip unit support unit 13. For example, a strain sensor is employed as the load change detection unit. The load applied to the grip portion 40 and the grip portion support portion 13 is minimum in (operation 4) of the knee flexion / extension motion, and is maximum in (operation 3). For this reason, the calculation unit 60 of this modification has a second output greater than the first predetermined value corresponding to (Operation 3), and the output of the load change detection unit exceeds the first predetermined value corresponding to (Operation 4). When it exceeds the predetermined value and becomes lower than the first predetermined value, it is determined that the knee flexion and extension exercise has been performed once.

  -A viewpoint guidance part can also be added to the exercise assistance apparatus 1 of each embodiment. For example, a laser pointer can be used as the viewpoint guiding unit. The viewpoint guiding unit displays a position for guiding the user's viewpoint in front of the exercise assisting apparatus 1. In the exercise assistance device 1 of this modification, the viewpoint is guided. For this reason, changes in the load on the soles during knee flexion and extension exercises are unlikely to differ from use to use. In addition, even between different users, the difference in changes in the load on the soles during knee flexion and extension exercises can be reduced. For this reason, the right foot load GR and the left foot load GL can be calculated more accurately. In addition, the user's knee flexion / extension exercise can be promoted appropriately.
