Description

Description Strength training method and strength training equipment Background technology

TECHNICAL FIELD The present invention relates to a muscle strength training method and a muscle strength training device that are effective for training the muscle strength of both legs, particularly the internal and external rotation muscles.

Conventionally, as shown in FIG. 24, for example, a tool for increasing the muscle strength of both legs is known. This device includes a chair 190 on which a user sits, and a foot rest bar 192 for placing both feet in the seated state. The two foot rest bars 192 are configured to be able to turn on a substantially horizontal surface about a substantially vertical axis, and are urged to both outsides by loads (not shown). The legs are strengthened by opening and closing both legs in the turning direction with the legs resting on the foot rest bars 192.

However, since this conventional device is designed to rotate on a substantially horizontal plane with both feet resting on the bar 192, improvement of the adductor muscle strength that rotates both thighs inward with respect to the pelvis can be expected. However, the strength of the internal and external rotation muscles for twisting the thighs in and out around the center axis can hardly be improved. These internal and external rotator muscles are also important muscles for kinematics, and it is desired to develop a means for efficiently training them.

In addition, in the above-described device, there is a possibility that a heavy load may be applied to the waist and the back due to excessive movement of the legs from the sitting posture.

The present invention has been made in view of the above circumstances, and provides a strength training method and a strength training device capable of effectively increasing the strength of the internal and external rotation muscles of both legs in a reasonable natural posture. With the goal. Disclosure of the invention

In order to solve the above problems, the present invention employs the following configuration.

That is, in the present invention, the knee of at least one leg is bent (preferably, the knee is bent by 30 ° or more and 160 ° or less), and at that position, the knee or the vicinity thereof is restrained by the restraining member. A strength training method for performing an outer pressing operation of pressing the knee or a portion in the vicinity thereof outward and an inner pressing operation of pressing the inner side against the restrained member without substantially moving the toe position of the leg. It is.

According to this method, the muscle strength of the external rotation muscle group in addition to the abductor muscle group is effectively trained during the outer pressing work, and the internal rotation muscle is added to the adductor muscle group during the inner pressing work. The group's strength is effectively trained.

This method does not necessarily need to be performed on both legs simultaneously, but may be performed on one leg at a time or on only one leg. However, both knees are almost aligned, and both knees or their vicinity are restrained from inside and outside by restraint members at that position while bending both knees. If the outer pressing work and the inner pressing work to press inward are performed, the sacroiliac joint will try to close in the outer pressing work and conversely the sacroiliac joint will open in the inner pressing work. However, such opening and closing movements of the sacroiliac joint can correct the distortion of the pelvis and the distortion of the central axis of the spine.

Here, the outer pressing operation and the inner pressing operation may be such that the position of the restraining member is fixed and the knee or the vicinity thereof is pressed against the restraining member, or the knee or the vicinity thereof is pressed against the restraining member. The portion may be moved in the pressing direction while applying a load in the direction opposite to the pressing direction.

In the case of the former method, the opening angle of the knee may be freely set, but if the opening angle is changed and the above-mentioned outer pressing work and inner pressing work are performed, more effective training can be performed. Regarding the latter method, the angle range for turning the knee may be freely set, By performing the inner pressing work to a position where the knee exceeds the center line of the body, it is possible to further expand the range of muscle strength enhancement.

It is preferable that the above method be performed in the most relaxed position, with the upper body lying substantially horizontally, but if necessary, such as when the trainee has a bad waist, the upper body may be raised as appropriate.

The present invention also provides a strength training device for carrying out the above-mentioned training method, which has an inner restraint portion for restraining both knees in a bent state or a portion in the vicinity thereof from the inside and an outer restraint portion for restraining the knee from the outside. It is provided with a restraining member, a turning support member that supports the restraining members so as to be able to turn about a substantially horizontal axis, and turning fixing means for fixing each of the restraining members at a predetermined turning angle.

When this device is used, for example, both knees are bent upward while lying on their back on the floor, etc., and set on each restraint member. The muscle training method described above can be easily executed simply by applying force.

Furthermore, by providing a turning drive means for turning both the restraint members symmetrically and fixing them at a predetermined turning angle, the turning angle positions of the two restraint members can be easily adjusted by the drive means.

In addition, if at least one of the inner restraint portion and the outer restraint portion is configured to be adjustable in the left and right directions with respect to the restraint member main body, the position is adjusted according to the width of the knee or a portion in the vicinity thereof. Regardless of the width, the knee or the vicinity thereof can be restrained in a suitable state from both inside and outside.

However, if the position of the inner restraint is made adjustable, the distance between the inner restraints will change due to the position adjustment.For example, if the inner restraint is largely moved to the center, the inner restraint It is difficult to set the turning angle of the restraint member because of the possibility of interference. However, if the outer restraint is configured to be adjustable in the left-right direction, the position of the inner restraint is fixed. The turning angle can be easily set. For example, The two restricting members can be pivoted between a pivoting position in which the both inner restricting portions contact or almost contact each other in a vertical state and a pivoting position in which the both inner restricting portions expand by a predetermined limit angle.

Here, if the above-mentioned limit angle is set to 60 ° and the restraining members are not turned outward beyond this limit, there is no danger of damaging the hip joint or the like due to excessive leg opening.

Further, there is provided an overall support member that supports the pivot support member so as to be pivotable about an axis substantially parallel to the pivot axis of each restraint member, and an overall fixing means that fixes the pivot support member at a predetermined pivot angle position. By doing so, training with uneven left and right can be performed with both restraining members tilted to one side. This training is performed with one knee twisted inward beyond the body center line, so that the adductor muscle group and the internal rotation muscle group can be further strengthened.

Further, the present invention provides a restraining member having an inner restraining portion for restraining a bent knee or a portion in the vicinity thereof from the inside and an outer restraining portion restraining the portion from the outside, and the restraining member can be pivoted about a substantially horizontal axis. A strength training device comprising: a turning support member for supporting the turning member; and a resistance adding means for applying a resistance in a direction opposite to the turning direction when the restraining member turns. According to this device, it is possible to exercise while actually moving the knee or the vicinity thereof in the pressing direction.

Although this device may have only a single restraining member, it has a pair of left and right restraining members that individually restrain the left and right knees, and these restraining members can be turned around axes parallel to each other. If the above-mentioned turning support member is configured to support the knee, it becomes possible to perform training for simultaneously turning the knees.

Also in this device, it is more preferable that at least one of the inner restraint portion and the outer restraint portion is configured to be position-adjustable in the left-right direction with respect to the restraint member body.

In addition, if a turning fixing means for fixing the restraining member at a predetermined turning angle position is provided, it is also possible to implement a muscle strength training method in which a knee or a portion in the vicinity thereof is pressed against the restraining member without moving the restraining member. The versatility of the device increases. Regardless of the specific configuration of the resistance adding means, for example, the torque adding means may be directly coupled to the turning axis of the restraining member. However, the turning motion of the restraining member is converted into the lifting motion of the weight. If a motion conversion mechanism is provided, it is possible to apply an appropriate load with a simple configuration using only the weight of the weight without providing a special drive source. Furthermore, it is possible to switch between a state in which the inward turning motion of the restraint member is converted into a lifting motion of the weight and a state in which the outward turning motion of the restraining member is converted into a lifting motion of the weight. In addition, if the motion conversion mechanism is configured, it is possible to apply an appropriate load to both the outer pressing work and the inner pressing work using a common weight. In addition, a plurality of weights can be mounted, and a lifting member that moves up and down together with the weight in the mounted state is provided. If the number of weights mounted on the lifting member can be adjusted, the weight of the weight can be adjusted. The size of the load can be freely adjusted by selecting the number.

In each of the above devices, since the surfaces of the inner restraint portion and the outer restraint portion are made of elastic members, even if the knee or a portion near the knee is strongly pressed against these restraint portions, there is no risk of damaging the portions.

Further, in addition to the restraining member and the like, a body supporting member having a first supporting portion for supporting the buttocks and the upper body and a second supporting portion for placing a foot with the knee bent is provided. More preferably, the restraining member is configured to pivot about an axis substantially parallel to an axis connecting the buttocks placed on the part and the feet placed on the second support part. According to this configuration, the training can be performed in a more stable and appropriate posture by placing a predetermined part of the body on each of the support portions.

Furthermore, if the backrest for supporting the upper body of the first support portion is configured to be able to rise and fall with respect to the seating portion on which the buttocks are placed, it is possible to perform training in both the supine position and the sitting position Become.

With the above equipment, the trainee may proceed with the training manually. Instructing the content of training according to a preset program (for example, instructing the turning angle of the restraint member, the direction in which force is applied to the knee, the time, etc.) Can be easily and automatically executed.

Further, the above-mentioned instruction means stores a plurality of types of programs set in advance, and instructs the contents of training according to the program selected before use, whereby the trainee can use his or her own A convenient program can be selected according to the physical strength and the time available for training, and the usability is further improved.

Next, the operation of the device and the method of using the device (ie, the method of training the strength) will be described with reference to the flow chart in FIG. 7 and FIGS. 8 (a) to (f).

0) Position adjustment of each support (Step S O in Fig. 7)

Before use, adjust the position of each part according to the trainee's body shape.

First, with both restraining members 30 at the initial position, the buttocks 50 are placed on the seating plate 12, and both feet 52 are placed on the foot rest bar 14. At this time, the knees 53 are bent in an upward state, but the knees 53 or the vicinity thereof are located between the inner restraining portion 33 and the outer restraining portion 34 of each restraining member 30. Adjust the position of the seating plate 50 in the front-rear direction so that

Next, loosen the screws 36 of both the restraining members 30 and bring the inner portions of both knees 53 into contact with the inner restraining portions 33 until the outer portions of the knees 53 are almost in contact. Slide both outer restraints 34 and tighten screws 36 at this position to secure outer restraints 34. In other words, the inner restraint portion 33 and the outer restraint portion 34 restrain each knee 53 or the vicinity thereof from the left and right.

It is preferable that the backrest 13 be laid down as much as possible. However, if the trainee has a bad waist or wants to perform another work such as reading while training, the backrest 13 may be used at an appropriate angle.

1) Program selection (Step S 1)

The main switch (not shown) on the main body side of the turning device 20 is turned on, and the power switch 43 on the remote controller 40 is operated for a predetermined time to turn it on. As a result, the turning instruction switch 48 is turned on, and 0 ° is displayed as the current arm opening angle on the numeral display section 41. When the turning instruction switch 48 is kept pressed for a predetermined time in this state, the display "P1" indicating the first program is displayed on the numeric display section 41. After that, each time you press program switch 4 or 5, 1 ”→“ P 2 ”→“ P 3 ”→“ P 1 ”—… The order is switched, so that the desired program is displayed (for example, if you want the third program,“ P 3 ” Press the start button 4 6 in the displayed state). As a result, the program is selected.

In the present invention, the number of types of the program and the specific contents are not particularly limited, and may be set as appropriate. For example, the working time may be changed by a program, or the turning angle of each restraining member 30 may be changed. In the following, a description will be given of the work content when the third program “P 3” is selected in the present embodiment.

2) Outward training at 0 ° arm opening angle (ie initial position) (Step S 2)

Since the turn command button 47 is turned on by operating the start button 46, the turn command button 47 is kept pressed for a predetermined time. As a result, the number display section 41 displays the current turning angle of 0 °, and the outward arrow lamp is lit on the direction display section 42 as a display of the direction in which force is applied to the knee. Further, the timer button 47 lights up, so press the button 47 this evening. As a result, 5, 4, 3, 2, 1, 0 and the number of seconds are counted down in the number display section 4 1, and the knees 53 are pressed against the both outer restraining sections 3 4 for only 5 seconds (that is, both sides). Apply force to open knees 5 and 3) Perform outer pressing work

(Fig. 8 (a)). This operation may be performed once or the program may be set to be performed intermittently multiple times.

After the above operation, first, the turn command button 47 is turned on, so that the turn command button 47 is kept pressed for a predetermined time. As a result, the motor 26 of the turning device 20 is operated, and the lifting block 25 is raised by a predetermined amount to turn both the restraining members 30 to the right and left outer sides by 10 ° each. 1 is the current arm opening angle 2 Display 0 °. In the same manner as above, the outward arrow is lit as an instruction of the direction in which force is applied to the knee, and the timer 47 is illuminated. Perform the outer pressing work for 5 seconds at this angular position (Fig. 8 (b )). It is preferable that the force of the knee 53 be released while the restraining member 30 is turning.

4) Outward training with arm opening angle 40 ° (Step S 4)

After the work in 3), after an appropriate rest period, perform outward training at an arm opening angle of 40 °. After the above operation, first, the turn command button 47 is turned on, so that the turn command button 47 is kept pressed for a predetermined time. As a result, the motor 26 of the turning device 20 is actuated, and the elevating block 25 is further raised to turn both the restraining members 30 to the left and right outer sides by another 10 °, and the numeral display section 41 displays the current arm opening angle. Display 4 0 °. In the same manner as above, the outward arrow is lit as an instruction of the direction in which force is applied to the knee, and the timer button 47 is illuminated. Perform the outer pressing work at this angular position for 5 seconds (Fig. 8 (c)). ).

5) Inward training at arm opening angle of 40 ° (Step S5)

After the work in 4), perform an inward training with the arm open angle of 40 ° after an appropriate rest period. After the above operation, the angle display flashes once, the direction indicator 42 lights up, the arrow changes from outward to inward, and the timer button 47 lights up. Then, press this timer button 47 and press the inner pressing work for 5 seconds in the same manner as above, that is, press both knees 53 against both outer restraints 34 (force the knees 53 in the closing direction). (Figure 8 (d)).

6) Inward training at 20 ° arm opening angle (Step S 6)

After the work in 5), after an appropriate rest period, perform inward training at an arm opening angle of 20 °. After the above operation, first, the turn command button 47 is turned on, so that the turn command button 47 is kept pressed for a predetermined time. As a result, the motor 26 of the turning device 20 is operated, and the lifting block 25 is lowered this time so that the two restraining members 30 are moved inward. While turning by 0 °, the numerical display section 41 displays the current arm opening angle 20 °. In the same manner as above, the inward arrow lights up as an instruction of the direction of applying force to the knee, and the evening button 47 lights up. Perform the inner pressing work for 5 seconds at this angular position (No. 8) Figure (e)).

7) Inward training at 0 ° arm opening angle (Step S 7)

After the work in 6), perform an inward training at an arm opening angle of 0 ° after an appropriate rest period. After the above operation, first, the turn command button 47 is turned on, so that the turn command button 47 is kept pressed for a predetermined time. As a result, the motor 26 of the turning device 20 is actuated, and the lifting block 25 is lowered to the original lowermost position to return the two restraining members 30 to the initial position, and the numeral display section 41 displays the current arm. Displays the opening angle 0 °. In the same manner as above, the inward arrow is lit as an instruction of the direction in which force is applied to the knee, and the evening button 47 is illuminated. Perform the inner pressing work for 5 seconds while maintaining this angular position (Fig. 8 ( e))). Thus, a series of training work set in the program is completed. In addition, if the trainee wants to perform the training according to his / her own method instead of training based on such a program, the manual button 44 may be pressed. Even at this time, since the arm opening angle is restricted to a maximum of 60 °, there is no fear of damaging the hip joint by opening both restraining members 30 by mistake.

In the above-described strength training method, as shown in FIG. 9 as a schematic diagram, the two legs 52 are aligned, and the knee 53 is bent upright, and a substantially horizontal axis (an axis approximately equal to the axis connecting the buttocks and both feet) A force in the direction of opening and closing is applied to the knee 53 in a substantially vertical plane around the axis in the depth direction in the figure. Therefore, the muscle strength of the internal and external rotator muscles, which could hardly be trained with conventional instruments Can be effectively improved, and furthermore, pelvic distortion and the resulting correction of 0 and X legs can be expected.

Specifically, as shown in Fig. 10 (a), when applying inward force to both knees 53, the internal rotation and adductor muscle groups 56 are strengthened and the sacroiliac muscle is strengthened. Joints 5 and 5 try to open, Conversely, when outward force is applied to both knees 53 as shown in Fig. 13 (b), the external rotation and abduction muscle groups 57 are strengthened and the sacroiliac joints 55 close. And Therefore, the training of the internal and external rotation muscles can be performed in a well-balanced manner by both exercises, and the distortion of the pelvis and the spine central axis is naturally corrected by the opening and closing movement of the sacroiliac joint 55. In fact, it has been confirmed that the implementation of this method corrects the O-leg and X-leg caused by the pelvic distortion.

In addition, since this method is performed in the most relaxed position of a person who lays his / her upper body on his / her knees, it is impossible to make the impossible movements when opening and closing the entire leg in a sitting position as in the past. There is no danger of excessive strain on the waist and back.

In addition, in implementing this training method, if the above-mentioned strength training device is used, an operation of simply inserting both knees 53 between the inner restraint portion 33 and the outer restraint portion 34 of each restraint member 30 is performed. Accordingly, the training method can be easily executed, and the opening angle of both knees 53 can be freely changed by turning of both restraining members 30. Furthermore, by switching to the program mode, it is possible to automatically execute a suitable training method according to a preset program.

A second embodiment is shown in FIGS. 11 (a) and (b). Here, the two support members 30 are supported by the swing support member 70 so as to be able to swivel around a substantially horizontal axis, and the swing support member 70 has an arc shape centered on the swing center axis of each of the restraint members 30. A plurality of pin insertion holes 71 are provided. A pin insertion hole is also provided in the support arm 32 of each restraining member 30, and a pin hole of the support arm 32 is inserted into an appropriate pin hole 71 of the turning support member 70. By passing the pins 72 through both the pins 揷 through holes 71 in the aligned state, each restraining member 30 can be fixed at a plurality of turning angles.

Even if such a device is used, the strength training method according to the present invention can be implemented by fixing the two restraining members 30 at the symmetrical turning angle positions.

Next, the procedure for using this device and its operation will be described.

A) When performing dynamic outer pressing while applying a load

With the weight 1 1 5 of the load generator 1 10 and the lifting plate 1 1 3 lowered, The lever 97 and the wires 10 OA and 10 OB in FIG. 7 are connected to the pulleys 93 A and 93 B at the solid line positions in FIG. Also, in this state, the through hole 95a into which the pin 89 is inserted is selected as the central through hole 95a so that the two support arms 37A and 37B face right above.

On the other hand, in the load generator 110, the number of weights 115 to be used is adjusted according to the desired load. For example, if you want to use two weights 1 15, as shown in Fig. 21, the through hole located in the gap between the second weight 1 15 and the third weight 1 15 from the top Insert the weight support pins 1 17 into 1 14 a. In this state, as in the first embodiment, the knee 5 is bent between the inner restraint portion 33 and the outer restraint portion 34 of each restraint member 30 by placing the buttocks on the seating plate 12. 3 or its vicinity, and put both feet 52 together on the footrest 14 '. Then, the outer pressing work is performed from this state.

By this operation, the support arms 37A and 37B pivot outward, but the pivoting force of the support arms 37A and 37B is reduced by the pulleys 92A and 92B and the pulley 93 A, 93B converts it into a force to pull the wires 10OA, 100B, and the lifting plate 113 connected to these wires 10OA, 100B is pulled upward. A shaft 1 14 is fixed to the lifting plate 1 13, and the weight 1 1 5 above the pin 1 17 is lowered by the weight support pin 1 17 inserted into the shaft 1 1 4. As a result, the weights 115 and the lifting plates 113 are lifted by the body. Therefore, resistance (load) is given to the outer pressing work by these weights.

B) When performing dynamic inner pressing work while applying load

With the weight 1 1 5 of the load generator 1 10 and the lifting plate 1 1 3 lowered, pull the lever 97 and the wire 10 OA, 100 B of Fig. 17 with the pulleys 93 A, 93 B. Is connected to the position indicated by the two-dot chain line in FIG. Also, this state

Two In this state, the through-hole 95a passing through the pin 89 is selected as the through-hole 95a from the outside so that the support arms 37A and 37B open to the outside by a predetermined angle.

In this state, as in the case of A), the buttocks are placed on the seating plate 12 and the knee 53 in a bent state between the inner restraint portion 33 and the outer restraint portion 34 of each restraint member 30 or The part near that part is sandwiched, and both feet 52 are placed on the footrest 14 '. Then, the inside pressing work is performed from this state.

As a result of this operation, the support arms 37A and 37B pivot inward, and the pivoting force of these support arms 37A and 37B also becomes the same as in the case of A). 9 2 B and pulleys 9 3 A, 9 3 B convert the wires 10 OA, 10 OB into pulling force, and lift plates 1 13 and 13 connected to these wires 100 A, 100 B A predetermined number of weights 1 15 are lifted. Therefore, resistance (load) is given to the inner pressing work by these weights.

The above description refers to the case where both legs are pressed outward or inside simultaneously, but it goes without saying that training can be performed on only one leg. In addition, in the case of only one leg, for example, the through hole 95a should be selected so that both support arms 37A and 37B both fall right (or left) in the initial state shown in FIG. By doing so, it becomes possible to train the left leg (or right leg) to move inward beyond the center line of the body, and it is possible to further strengthen the adductor muscle and the inner rotation muscle.

C) When performing static pressing

With the weight 1 15 of the load generator 1 10 and the lifting plate 1 1 3 lowered, pull the levers 97 and wires 100 A, 100 B of FIG. 3 B is connected to the position indicated by the solid line in FIG. In this state, the support arms 37A and 37B are opened symmetrically left and right outward by a predetermined angle, or the through holes 95a through which the pins 89 are inserted so as to face right above. Is selected. On the other hand, in the load generator 110, the ascending restriction pin 118 is inserted into the through hole 109a. In this state, as in the case of A), the buttocks are placed on the seating plate 12 and the knee 53 in a bent state between the inner restraint portion 33 and the outer restraint portion 34 of each restraint member 30 or The part near that part is sandwiched, and both feet 52 are placed on the footrest 14 '. Then, the outer pressing work is performed from this state.

With this operation, each support arm 37A, 37B attempts to pivot outward, and the force is applied by the pulleys 92A, 92B and the pulleys 93A, 93B to the wires 100A, 1B. The force converted to the force that pulls 0 0 B These lifting wires 1 1 0 3 connected to these wires 1 0 OA and 1 0 OB are prevented from floating by the presence of the lifting control pins 1 1 8 37 A and 37 B cannot turn. Therefore, similarly to the first embodiment, it is possible to perform the static outer pressing work in a state where the restricting member 30 is fixed.

Conversely, if the position of the lever 97 in FIG. 17 is switched from the outside of the figure, that is, to the position indicated by the two-dot chain line, the support arms 37 A and 37 B are directed inward. In this state, static inner pressing work can be performed because the turning to the right side is prevented.

In this embodiment, the turning resistance (load) is generated by using the weight of the weights 115. However, for example, a torque generating means is provided on the turning shafts of the support arms 37A and 37B. You may make it connect directly. However, with the above-described configuration, a special drive source is not required, and effective training can be performed with a simple configuration using only the weight of the weights 115. In addition, by using the weight support pins 117 and the like so that the number of the weights 115 attached to the elevating member can be selected, the load can be freely adjusted.

In addition, the present invention can take the following forms.

(1) In the device according to the present invention, regardless of a specific mechanism for driving the both restraining members 30 to pivot or to pivotably support the two restraining members 30, for example, using a gear mechanism or the like. Can be turned symmetrically. Also in this case, if the gear mechanism or the like is positively driven by a motor or the like, the device according to claim 9 is constructed. If the gear mechanism or the like is given rotational resistance by a weight or the like, the device according to claim 15 can be constructed.

(2) In the device according to the first embodiment, the inner restraint portion 33 side is directly rotated and driven, and the outer restraint portion 34 following the inner restraint portion 33 is configured to be capable of adjusting the position in the left-right direction. The outer restraining portion 34 may be driven to rotate so that the inner restraining portion 33 can be adjusted in the left-right direction, or the two restraining portions 33, 34 may be fixed. . However, if at least one of the restraints can be adjusted in position, it can be restrained in a close contact condition from both inside and outside regardless of the width of the knee, and the quality of training can be improved. In particular, if the position of the outer restraint portion 34 can be adjusted and the inner restraint portion 33 is driven to rotate, the outer restraint portion 34 is driven to rotate and the inner restraint portion 33 is positioned inside. This has the advantage that the setting of the opening angle can be made easier than in the case in which the opening angle is increased. The same applies to the case where the restraining member 30 is pivotably supported to provide resistance in the pivoting direction.

(3) In the drawing, the restraining portions 33 and 34 are shown as being connected at the upper side, but they may be so-called bifurcated portions connected at the lower side.

(4) In the device according to the present invention, it is possible to omit the support frame 10 and perform training only with the turning device 20 and the restraint member 30. In this case, for example, the turning device 20 is placed directly on the floor or the like, and stands on the floor or the like while lying on the back in a knee state so that the knee or the vicinity thereof is restrained by the two restraining members 30. do it. However, if the support frame 10 is provided, there is an advantage that a proper training posture can be easily, stably and appropriately taken only by placing a predetermined part of the body on each support portion.

Further, the training method according to the present invention can be executed even by using another device or the like without using the above device. —

(5) The bending angle of the knee 53 when performing the outer pressing operation and the inner pressing operation may be set as appropriate. However, as shown in FIG. 23 (a), the bending angle of the knee 53 (that is, the angle of the lower leg 58B with respect to the center extension line of the thigh 58A) is less than 30 °. In the case of (1), the internal rotation of the lower leg 58B has occurred before the work, and it is difficult to obtain the range of rotation of the lower leg 58B, which is the target of this training. It is difficult to make the bending angle 0 of the knee 53 larger than 160 ° as shown in Fig. 4 because of the structure of the lower limb. Even if this training is performed in this state, the lower leg 5 Since the external rotation of 8B has occurred, the range of motion of the lower leg 58B intended for this training is still difficult to obtain, and the muscles on the entire surface of the thigh 58A are overstrained and the exercise is performed. Since the knee bending angle itself is difficult, the knee bending angle 0 is preferably set to 30 ° or more and 160 ° or less. Industrial applicability

As described above, according to the present invention, it is possible to effectively increase the muscular strength of the external and internal rotator muscles, which can hardly be trained by the conventional method, and to easily and appropriately apply the muscular strength training method. Can be provided.
