Japanese Patent No. 5629807

During exercise, the lower leg is easily loaded. In particular, when repeated exercises involving a dash, jump, sudden change of direction, and the like are performed, the burden on the lower leg increases, and a great stress is applied to the tibia, which is a column that supports the load in the lower leg. In recent years, many cases have been reported in which tibia overworked periosteitis (shin splint) develops due to repeated excessive stress on the tibia. On the other hand, conventional support wear cannot sufficiently relieve stress on the tibia, and athletes and general exercisers often exercise while having a risk of developing a sprint.
The present invention has been made in view of the above problems, and an object thereof is to provide support wear capable of effectively suppressing the occurrence of a thin sprint.

It is a figure explaining the skeletal structure of a human body leg.

At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
Support wear worn by the human body, corresponding to the position of at least the lower thumb flexor and the long flexor at the front side of the lower leg of the human body, above the ankle condyle in the region inside the tibia An X portion for applying a first tightening force to the region, a V portion for applying a second tightening force weaker than the X portion to a region obliquely above and outside the X portion, the X portion and the V portion A W portion for applying a third tightening force weaker than the V portion in a region corresponding to the position of the anterior tibial muscle between the posterior side of the human crus and the inner side of the tibia A region K that applies the first tightening force to a region corresponding to at least the position of the medial head of the soleus and gastrocnemius muscle above the ankle condyle in the region, and a region obliquely above and outside the K portion I portion for applying the first tightening force to the first portion, the K portion and the I portion A portion J corresponding to a position corresponding to a position where the gastrocnemius medial head and the gastrocnemius external head contact each other, and a fourth tightening force weaker than the W portion, and the X portion and the K portion are Supportware connected, wherein the V unit and the I unit are connected.
According to such support wear, the shock that reaches the tibia during exercise or the like can be mitigated by protecting the muscle that supports the load of the tibia by the X portion and the K portion having the strongest tightening force. In addition, since a force concentrating from the outside to the inside acts on the lower leg, the varus of the knee joint is suppressed, and the torsional stress of the tibia is easily relieved. By these actions, the occurrence of a thin splint can be effectively suppressed.

In this support wear, it is preferable that the X part is connected to the W part and the K part without joints, and the V part is connected to the W part and the I part without joints.
According to such support wear, the fit at the time of wearing can be improved. In addition, muscles, ligaments, and the like can be efficiently supported by causing the tightening forces to interact with each other in adjacent regions.

In this support wear, a Y portion for applying the third tightening force to a region corresponding to the position of the ankle external condyle on the front side of the crus, and the ankle joint outside on the back side of the crus It is desirable to have an L portion for applying the third tightening force in a region corresponding to the position of the condyle.
According to such support wear, since the tightening force applied to the inside of the tibia is stronger than the tightening force applied to the outside, it is possible to easily receive the load applied to the inner portion of the tibia.

The support wear corresponds to a P portion that applies the first tightening force to a region corresponding to the position of the superior anterior iliac spine, and a position that moves from the muscle tendon transition portion of the sewing muscle to the muscle abdomen. It is desirable that the region has a Q portion for applying the fourth tightening force, and the P portion and the Q portion are connected.
According to such support wear, it is possible to apply a tightening force with two levels of strength to the sewing muscles that carry out hip joint abduction and rotation. By weakening the support of the sewing muscle in this manner, excessive hip abduction / external rotation motion can be suppressed, and the leg swing-up operation in the propulsion direction can be easily performed. Moreover, since it becomes difficult for the hip joint to face outward, it is possible to reduce the twisting of the tibia and to prevent the occurrence of a thin splint.

It is preferable that the support wear has a Z portion that applies the first tightening force in a region corresponding to the position of the thin line.
According to such support wear, it is easy to contract the hip adductor muscle by strengthening the tightening force to the hip adductor muscle that has the antagonistic action of hip abduction and rotation, and supporting the hip adductor muscle can do.

In such support wear, an S portion that applies the first tightening force to a region corresponding to the position of the inner side surface of the femur that is diagonally below the Q portion and below the Z portion. It is desirable to have.
According to such support wear, the Z portion that supports the hip adductor muscle group and the thin muscle and the Q portion that supports the sewing muscle can be joined at the S portion. In this case, by linking the sewing muscles and hip adductor muscles that work almost simultaneously, the leg swing-up operation can be made easier than in the case where the sewing muscles are supported alone. Moreover, since it becomes easy to control the flow of the legs in the hip joint abduction / rotation direction, it is possible to make the thin splint less likely to occur.

In this support wear, the third tightening is performed in a region corresponding to the upper part of the muscle abdomen where the muscle mass of the biceps femoris increases from the tendon attached to the sciata above the biceps femoris and the muscle tendon transition portion. It is desirable to have an E part that applies force, and to have a G part that applies the first tightening force to a region including the radial head from the lower part of the E part.
According to such support wear, the biceps femoris that exerts the most power during the internal rotation of the lower leg above the knee joint is supported by the strongest tightening force, and the upper part of the muscle abdomen is used to pull out the muscles more easily. Supported by tightening force. As a result, the biceps femoris can efficiently perform eccentric contraction, and excessive sliding of the ribs during internal rotation of the lower leg can be suppressed, so that a thin splint can be made less likely to occur.

In such support wear, the first tightening force is applied to the position where the femoral fascia intestinal muscle moves from the upper part of the greater trochanter to the lower part and the region corresponding to the entire region of the intestinal shin ligament. It is desirable that the G part and the B part are connected to each other.
According to such support wear, the G part that supports the biceps femoris and the B part that supports the intestinal shin ligament having the same effect as the biceps femoris regarding the control of the crus internal rotation are joined. By doing so, the force which suppresses the slip of the rib at the time of internal rotation of the lower leg is more strongly exerted, and the excessive internal rotation of the lower leg can be easily suppressed. Therefore, it is possible to make the thin splint less likely to occur.

In such support wear, it is desirable that the B part and the I part are connected.
According to such support wear, the outer side collateral ligament is supported with a stronger force due to the cooperation of the B part and the I part, and the blurring of the knee joint to the outside is suppressed, and the inside of the tibia The load stress of is reduced. This can reduce the risk of developing a sprint.

It is preferable that the support wear has an A portion for applying the first tightening force in a region corresponding to the position of the greater gluteus, and the A portion and the B portion are connected.
According to such support wear, when the A part supports the gluteal muscle with the strongest tightening force, the hip adduction / inward rotation action can be performed by linking with the B part that supports the femoral fascia intestinal muscle. It works well when kicking up, making it easy to put your feet straight.

It is preferable that the support wear has an H portion for applying the third tightening force in a region corresponding to the position of the center of the hamstrings above the knee joint.

=== Embodiment ===
<< Basic configuration of Spats 10 >>
As an example of support wear according to the present embodiment, a spats 10 that is worn on the lower body of a user will be described. FIG. 1 is a plan view showing the entire front side and rear side of the spats 10.

  The spats 10 of the present embodiment are wear-in support wear that covers the waist and both feet (a pair of legs) of the human body when worn. The spats 10 are clothing made of stretchable fabric, and when worn on the human body, they fit the human body and apply a tightening force to a predetermined part of the human body. Here, the “tightening force” refers to a force generated by the tension of the fabric and tightening and braking or protecting muscles, ligaments, bones and the like. Each part of the human body is supported by the tightening force.

  And the spats 10 have four types of cloth portions with different degrees of expansion / contraction. That is, the spats 10 include a first region represented by black in FIG. 1, a second region represented by right oblique lines, a third region represented by left oblique lines, and a fourth region represented by white paint. And having a region. Here, the degree of expansion / contraction is the ease of expansion / contraction. The degree of expansion / contraction is small (it is difficult to expand / contract) is the nature of the fabric that is easy to maintain the original state (the state where no external force is applied) (that is, it does not stretch unless a large external force is applied, and the external force is released in the stretched state) In this case, it represents the property of being easily returned to the original state), and the degree of expansion / contraction is large (easy to expand / contract) is the property of the fabric that is difficult to maintain the original state (that is, stretched and stretched with a small external force) When the external force is released, the property is difficult to return to the original state.

  In the present embodiment, since the degree of expansion and contraction of the fabric of the spats 10 is set in four stages, the tightening force applied to predetermined sites such as muscles, ligaments, bones, etc. when the spats 10 are worn on the human body, There are 4 levels. As a matter of course, the tightening force becomes weaker as the fabric expands and contracts.

  The first region is a portion that applies a first tightening force (hereinafter also referred to as the strongest tightening force) that has the smallest degree of expansion and contraction and is the strongest tightening force on muscles and the like. The second region is a portion to which a second tightening force (hereinafter also referred to as a strong tightening force) that is a tightening force weaker than the first tightening force is applied. The third region is a portion that applies a third tightening force (hereinafter also referred to as a medium tightening force) that is a tightening force weaker than the second tightening force. The fourth region is a portion to which a fourth tightening force (hereinafter also referred to as a weak tightening force), which is a tightening force weaker than the third tightening force, is applied.

  The strength of the four-stage tightening force is determined according to the stress (load) measured by the elongation recovery measurement based on “JIS L 1096 Fabric and Knitted Fabric Test Method”. In the present embodiment, a test piece (for example, a rectangular sheet piece having a width of about 50 mm and a length of about 300 mm) collected from each of the first to fourth regions having four levels of tightening force is prepared, and the test piece is obtained using a tensile tester. Is stretched until it reaches a predetermined elongation, and the stress at that time is measured. Thereafter, the load is decreased, and the stress when the test piece reaches a predetermined elongation is measured. The tightening force is determined based on the magnitude of the stress when this operation is repeated a plurality of times.

  FIG. 2 is a table representing stress measurement data for four levels of tightening force. In this embodiment, the operation | movement which makes the test piece which has the 1st-4th tightening force expand | stretched to 40% of elongation, respectively, and is recovered was repeated 3 times. Then, the stress when the elongation of each test piece becomes 30% in the stretching operation and the stress when the elongation of each test piece becomes 30% in the recovery operation are measured, and the average value is 30. It was recorded as% elongation stress. The above-mentioned “elongation” represents the ratio of the length of the test piece after extension to the test piece before extension. For example, if the elongation is 30%, it represents a state in which the test piece has been extended to a length 1.3 times the original length of the test piece.

  As shown in FIG. 2, the 30% elongation stress has the highest first tightening force (strongest tightening force) at 167.7 (cm · N) and the second tightening force (strong tightening force) is 135.2. (Cm · N), the third tightening force (medium tightening force) is 112.8 (cm · N), and the fourth tightening force (weak tightening force) is 102.3 (cm · N), gradually increasing to 30%. It can be seen that the elongation stress decreases. The larger the 30% elongation stress is, the larger the stress required for extending the test piece is. Therefore, the first tightening force (strongest tightening force) is the least likely to stretch (the degree of expansion and contraction is small). It is clear that the tightening force (weak tightening force) is the easiest to stretch (the degree of expansion / contraction is large). However, the data shown in FIG. 2 is an example, and the strength of the tightening force is not limited to this. The power difference between the first tightening force (strongest tightening force) and the fourth tightening force (weak tightening force) may be in the range of about 1.5 to 1.8.

  Further, in the spats 10, the first region to the fourth region are integrally formed without a joint. That is, the first region to the fourth region are not formed in the spats 10 by joining a plurality of types of fabrics having different tightening forces, but for each predetermined region of one fabric constituting the spats 10. The first region to the fourth region are formed by changing the magnitude of the tightening force. As a method of changing the magnitude of the tightening force, for example, a special resin processing for expressing stretchability is performed on the surface of the fabric to form a plurality of round areas, and the round areas are arranged like a polka dot pattern. To do. And the magnitude | size of clamping force is adjusted for every area | region by changing the magnitude | size (area) and arrangement | positioning space | interval of a resin-processed round area | region. By doing in this way, the 1st-4th area | region which has a different tightening force in the surface of the spats 10 is formed seamlessly. Since there is no joint between the regions, the fit is improved when the spats 10 are worn, and the muscles, ligaments, and the like can be efficiently made by making each of the adjacent regions easily interact with each other. Can support.

  Thereby, at the time of wearing the spats 10, four stages of tightening force is applied to a position corresponding to a predetermined part of the human body. The position corresponding to a predetermined part of the human body (for example, predetermined muscle, ligament, etc.) means a position covered by the spats 10 when the spats 10 are worn.

  In the present specification, regarding the relative positional relationship of the human body, the one closer to the head is “upper” and the one closer to the toes is “lower”. Further, it is assumed that the face or belly is facing “front side” and the back is facing “rear side”. Further, in the leg portion, the side facing the other leg portion is “inside”, and the opposite side to the inside is “outside”.

<< About the action of tightening force >>
How the tightening force generated in each of the first to fourth regions acts on which part of the human body when wearing the spats 10 will be described in detail. FIG. 3 is a diagram for explaining the tightening force applied to the human body by the spats 10 in a plurality of parts. FIG. 4 is a diagram for explaining the structure of muscles and ligaments on the front side of the human lower limbs. FIG. 5 is a diagram for explaining the structure of muscles and ligaments on the rear side of the human lower limbs. FIG. 6 is a diagram illustrating the skeletal structure of the lower limbs of the human body.

<Reinforcement of lower leg>
Thin splints (tibial overworking periosteitis) that occur in the lower leg are considered to be largely caused by the impact that acts on the tibia when a load is applied during exercise and the stress that occurs when the tibia is twisted. On the other hand, in the spats 10, the lower leg part is reinforced by the tightening force generated by the X part, V part, W part on the front side of the lower leg and the K part, I part, and J part on the rear side of the lower leg in FIG. This suppresses the occurrence of thin sprints. Note that the plurality of portions shown in FIG. 3 are regions set for convenience in order to explain the function of the spats 10, and in the actual spats 10, the boundary portions are not visible for each region. For example, the A part and the B part are both included in the first region having the strongest tightening force, and the boundary between the A part and the B part is not formed in the actual spats 10.

  Part X is the position of at least the lower part of the long thumb flexor and the long finger flexor (see FIGS. 4 and 5) above the intracondylar condyle in the region inside the tibia on the front side of the lower leg (see FIG. 6) This is a portion that applies the strongest tightening force (first tightening force) to the region corresponding to, preferably 2/3 of the total length of the tibia. The elbow flexor muscles and the long flexor muscles are portions that are susceptible to a large impact when the toes stand up when swinging up or landing during exercise such as running. In particular, the lower two-third region on the inner side of the lower leg is a portion where the frequency of developing a thin splint is high. Therefore, by applying the strongest tightening force to the region by the X portion and supporting it, the impact acting on the long finger flexor muscle group can be mitigated.

  K part is a region corresponding to at least the lower part of the medial head of the soleus and gastrocnemius muscles, preferably 2/3 of the total length of the tibia above the intracondylar condyles in the region of the tibia on the back side of the lower leg. This is the portion that gives the strongest tightening force (first tightening force) to the region. The soleus and gastrocnemius muscles are also prone to large impacts when the toes stand up when swinging up or landing. Therefore, as in the case of the X portion, by applying the strongest tightening force to the portion by the K portion and supporting it, the impact acting on the gastrocnemius muscle can be reduced.

  Thus, by protecting the muscle of a predetermined part by the X part and the K part having the strongest tightening force, it is possible to relieve the impact that reaches the tibia during exercise.

  Next, the twist of the tibia will be described. When a person runs or dashes and stands on the toes, the knee joint is in a flexed position with the lower leg slightly twisted inward (this state is also referred to as “inner rotation” of the lower leg). And, by the "inner rotation" of the lower leg, the weight at landing can be moved from the ribs to the toes, gradually moving the weight to the toes and finally coming to the ground contact period by standing on the toes leaving the floor It becomes like this. However, if the internal rotation of the lower leg becomes excessive, the kicking motion at the tip of the toe becomes unstable, and the stress due to loss of power, difficulty in moving in the propulsion direction, and twisting of the tibia is reduced. It can be a sprint factor. Such excessive internal rotation of the lower leg part is amplified by bending both lower limbs outward to form a so-called O-leg (this state is also referred to as “knee varus”). I know that.

  Therefore, in this embodiment, the torsion of the tibia is performed by controlling the knee varus by linking the above-described X part and K part with other regions (V part, W part, I part, J part, etc.). It is possible to relieve the stress caused by.

  The V portion is a portion that applies a strong tightening force (second tightening force) to a region above the anterior tibial muscle (see FIG. 4) that is obliquely above and outside the X portion. The W portion is a portion that applies a medium tightening force (third tightening force) to a region corresponding to the position of the center of the anterior tibialis muscle between the X portion and the V portion. Then, as shown in FIG. 3, the X portion, the W portion, and the V portion are seamlessly connected to each other, so that a continuous belt-shaped region (X portion, W portion, V, which extends obliquely upward and outward from the X portion). Part) is formed. This belt-shaped region has a structure in which the tightening force (strongest tightening force) of the X portion inside the crus acts more strongly than the tightening force (strong tightening force) of the V portion outside the crus. As a result, a force that concentrates on the inner side of the lower leg is generated in the region, and it is easy to suppress a torsional stress from being applied to the tibia by a force that falls outside based on the varus of the knee joint. That is, by controlling the pressure at which the tibia falls to the side (outside), it becomes easier to hold the tibia straight, and the load stress on the inside of the tibia can be reduced. Therefore, it becomes easy to relieve torsional stress of the tibia caused by excessive internal rotation of the lower leg.

  The medium tightening force is the strength of the tightening force applied by the W portion located between the X portion and the V portion on the front side of the lower leg. The W portion is located at the center of the anterior tibialis muscle. This is to prevent excessive contraction of the anterior tibial muscle during exercise. The anterior tibial muscle is a muscle that generates a large force by performing extensible contraction (also referred to as eccentric contraction) that exerts force while the muscle stretches when standing on the toe. Therefore, the tightening force applied by the W part is set to be weaker than that of the X part and the V part, and the extension when the anterior tibialis contracts eccentrically is allowed, thereby suppressing the knee varus and improving the human body. Can assist with various motor functions.

  Part I has the strongest tightening force (first tightening force) in a region (see FIG. 6) covering the radial head of the attachment part of the external tibial condyle and the lateral collateral ligament on the posterior side of the lower leg, obliquely above and outside the K part. ). The portion J is a portion that applies a weak tightening force (fourth tightening force) to a region (see FIG. 5) corresponding to a position where the gastrocnemius inner head and the gastrocnemius outer head contact each other between the K portion and the I portion. Then, as shown in FIG. 3, the K part, the J part, and the I part are seamlessly connected to each other, so that the posterior side of the lower leg part is continuous from the K part toward the outer condyle direction obliquely upward and outward. The strip-shaped region (K portion, J portion, I portion) is formed. Furthermore, in this embodiment, the X part and the K part are connected, and the V part and the I part are connected, so that the X part, the V part, the W part, the K part, the J part, and the I part The structure around the thigh is covered with a bias. Thereby, the force concentrated on the inner side of the crus as described above acts more strongly on the tibia, and it becomes easier to control the fall of the tibia in the outward direction when standing on the toe. As a result, it becomes easy to reduce the load stress to the inside of the tibia.

  The reason why the tightening force applied by the J portion located between the K portion and the I portion on the rear side of the lower leg is defined as the weak tightening force is that the J portion corresponds to the center position of the gastrocnemius muscle. For this reason, the expansion of the gastrocnemius during exercise is not excessively suppressed. The center part of the gastrocnemius muscle is the part that exerts the most power by increasing the expansion rate of the gastrocnemius muscle abdomen from the heel-contacting time of landing to the ground-contacting period, and weakens the tightening force applied by the J-part. It is set as the structure which is easy to accept the expansion to the side of a gastrocnemius abdominal muscle by setting.

  In addition, in the region from the lower part of the outer condyle of the distal part of the tibia to the half of the outer part of the front part of the crus facing the K part arranged on the inner part on the rear side of the crus, A Y portion that is a portion to which a tightening force (third tightening force) is applied is disposed. Similarly, in the region from the outer part of the rear part of the lower leg facing the X part arranged on the inner part of the front part of the lower leg part to about one third upward from the outer condyle of the distal part of the tibia, An L portion that is a portion to which a medium tightening force (third tightening force) is applied is disposed. By applying an intermediate tightening force, which is weaker than the strongest tightening force applied to the inner part of the tibia, to the outer part of the tibia by the Y part and the L part, the load applied to the inner part of the tibia can be easily received.

<Support for thin muscles, hip adductor muscles, sewing muscles, etc.>
When a person performs running or a dash, the foot can be landed in the propulsion direction by the hip abduction / external rotation acting at the same time as the hip abduction / external rotation acting during the leg swing-up operation. If the muscular strength of the hip adductor, which is responsible for the hip adductor action during this swing-up operation, is weakened, the abduction / external rotation direction during hip flexion, that is, the legs will face outward, making it difficult to land in the propulsion direction , Lateral shake occurs. As a result, the energy efficiency of muscular strength is deteriorated. The repetitive motion under such a situation accelerates the muscle fatigue of the kicking motion while standing at the toe in the lower leg and contributes to amplifying the torsional stress on the tibia as a support. That is, there is a risk of inducing a thin sprint.

  On the other hand, in the spats 10 of this embodiment, thin muscles, hip adductor muscles, sewing muscles, and the like are supported by the tightening force applied at each part such as the Z part, the P part, the Q part, and the S part. This suppresses the occurrence of a thin sprint due to a leg swing-up operation or the like.

  The Z portion is a portion that applies the strongest tightening force (first tightening force) to a region corresponding to the position of the thin muscle (see FIG. 4) that assists hip adduction. Specifically, it has a width to compensate for the muscle abdomen of the hip adductor muscle group (ie, short adductor, long adductor, major adductor) that adheres along the femur inside the thin muscle. However, the strongest tightening force is applied to the portion having a length from the pubic bone to which the thin muscles adhere to the pubic bone (the inner surface of the femur) to the heel where the thin muscles are attached. By tightening the tightening force to the hip adductor that forms the antagonistic action of hip abduction / rotation by the Z portion and supporting the hip adductor, the Z part can be easily contracted.

  The portion P is a portion that applies the strongest tightening force (first tightening force) to the muscle tendon transition portion of the sewing muscle, that is, the region corresponding to the position of the superior anterior iliac spine (see FIG. 6). Specifically, from the position including the upper anterior iliac crest located at the upper part of the hip joint at the lower outer side of the iliac crest, which is the attachment portion (starting portion) of the sewing muscle, the lower anterior iliac bone just below that The strongest tightening force is applied to the upper part of the quadriceps femoris and the outer half of the thigh, which passes through the upper part of the spine and acts together with the sewing muscle in the hip flexion movement. The Q portion is a portion that applies a weak tightening force (fourth tightening force) to a region corresponding to a position of the sewing muscle that transitions from the muscle tendon transition portion to the muscle abdomen. Specifically, a weak tightening force is applied to an intermediate portion corresponding to one third of the quadriceps on the front side of the thigh. In other words, the tightening force is applied to the sewing muscle carrying the hip joint abduction / rotation motion by the P portion and the Q portion with two levels of strength (the strongest tightening force and the weak tightening force).

  In conventional spats, a structure that makes it easy to swing up the legs by applying a strong tightening force to the sewing muscles was common, but with such a structure, the hip joint tends to face outward, and in the propulsion direction There was a problem that the knee joint was difficult to face. On the other hand, in the spats 10 of this embodiment, the tightening force by the Z portion that supports the hip adductor muscle group is strengthened while the tightening force by the Q portion that supports the muscular abdomen of the sewing muscle is intentionally weakened. Yes. In other words, the support of the hip adductor muscle group acting on the hip adduction is stronger than the support force of the sewing muscle acting on the hip abduction / rotation. Thereby, excessive hip joint abduction / external rotation motion of the swing-up leg can be suppressed, and the leg swing-up operation in the propulsion direction (the hip flexion direction forward) can be easily performed. Further, when the leg is swung up, the hip adduction operation is more dominant than the hip joint abduction / rotation operation, so that the leg is easy to face in the propulsion direction, and the lower leg just below it is easily guided to the load position. As a result, it becomes difficult for the hip joint to face outward, and it becomes easy to reduce the torsion of the tibia, which is the cause of the thin splint.

  Further, the spats 10 are provided with an S portion that imparts the strongest tightening force (first tightening force) to the region around the inner side of the femur that is obliquely below the Q portion and below the Z portion. . That is, the Z part that supports the hip adductor muscle group and the thin muscles and the Q part (and P part) that support the sewing muscles are arranged to join at the S part. By linking the sewing muscles and hip adductor muscles that work almost simultaneously, the leg swing-up operation can be made easier than in the conventional case where the sewing muscles are supported alone. That is, the strongest tightening force (Z part) supplementing the muscle group responsible for the hip adduction action, and the strongest and weakest tightening force (P) supplementing the sewing muscle responsible for the hip abduction / rotation motion in two stages Part and Q part) are joined together, it becomes easy to control the flow of the legs in the hip abduction / rotation direction, the legs can be easily swung up in the propulsion direction, and the landing can be facilitated.

<Biceps femoris support>
As one means for smoothly controlling the internal rotation movement of the above-described crus, in the spats 10 of the present embodiment, the biceps femoris muscle on the back side of the thigh (see FIG. 5) is supported (eccentric contraction). The reason for supporting the biceps femoris is as follows. That is, at the time of internal rotation of the lower leg part, a motion is generated in which the tibia pivots inward from the femur and comes off at the knee joint. At that time, a movement that slides inward also occurs in the rib connected to the tibia outside the tibia by the tibia joint. In response to this rib slip, the biceps femoris adhering to the rib is subjected to eccentric contraction so that the rib does not slip excessively. In other words, the biceps femoris acts so as to apply a brake so that the lower leg does not shift too much from the femoral surface. Therefore, by supporting the biceps femoris, the internal rotation movement of the lower leg can be controlled.

  Part E provides a medium tightening force (third tightening force) from the tendon attached to the sciatic bone above the biceps femoris and the muscle tendon transition region to the region corresponding to the muscle abdomen where the muscle mass increases. It is. Of the region where the biceps femoris are placed on the lower limbs of the human body, the region extending from the lower part of the gluteus muscle to the area around the long head tendon of the biceps is used when performing forward tilting during a dash and squatting during a jump. This is the position where maximum extension force is required. Therefore, in the E part, it is set as the structure which can be supported while avoiding giving strong tightening force with respect to a biceps femoris muscle and allowing expansion | extension of a biceps femoris muscle.

  G section has the width to cover the entire muscle abdominal area where the muscle mass of the biceps femoris is the largest, and is strongest from the lower part of E section to the area including the radial head where the muscle mass decreases and becomes a tendon. This is a portion to which a tightening force (first tightening force) is applied. Thus, even when the maximum traction force acts on the biceps tendon tendon or the like due to the movement of the ribs inward during internal rotation of the lower leg, the biceps femoris against the maximum traction force of the biceps tendon The muscles are likely to exert the greatest power. Further, since the G part is connected to the I part at the lower part, it is possible to support the biceps femoris muscle more strongly in conjunction with the strongest tightening force applied at the I part. In addition, since the region where the G portion is disposed is also a region where the knee joint outer side collateral ligament travels, there is an effect of strengthening the ability to protect the outer side collateral ligament.

  Thus, the strongest tightening force by the G part is applied to the position of the biceps femoris muscle, which is considered to exert the greatest force during the internal rotation of the lower leg above the knee joint. In order to draw out more, a medium tightening force by the E part is applied. Thereby, the biceps femoris can efficiently perform eccentric contraction, and excessive slippage of the ribs during internal rotation of the lower leg can be suppressed.

  Further, in the spats 10, the support function of the biceps femoris is enhanced by connecting the G part and the B part and linking them together. B part is outside G part, the position where the thigh fascia intestinal muscle moves from the upper part of the greater trochanter to the lower part of the greater trochanter (see FIGS. 4 and 6), and the outer part of the thigh below it. It is the part that gives the strongest tightening force (first tightening force) to the entire area of the intestinal shin ligament that connects to the tibia. The intestinal shin ligament supported by part B is attached to the external condyle above the tibia and is located on the outer side of the tibia where the biceps femoris is attached. Like the action, it is greatly related to the internal rotation control of the lower leg. Therefore, by combining the G part that supports the biceps femoris and the B part that supports the intestinal tibia ligament which has the same effect as the biceps femoris regarding the control of the crus internal rotation, the rib can be slipped. The force to suppress is exhibited more strongly and it can make it easy to suppress excessive internal rotation of the lower leg.

  In addition, this B part has the function to control the extensibility of the lateral collateral ligament not only in the intestinal shin ligament but also on the outer side of the knee joint and connecting the outer condyle of the femur and the rib of the lower leg. The lateral collateral ligament is a ligament that connects the external femoral condyle and the radial head, and is a part that controls the lateral displacement of the knee joint. In the spats 10, the B part is arranged along the outer thigh lateral collateral ligament, passes through the outside of the knee joint as it is, and the I part that supplements the radial head, which is the attachment part between the tibial condyle and the outer collateral ligament, Connected. Thereby, the outer side collateral ligament is supported by the strongest tightening force by the B part and the I part, and the protection level of the outer side collateral ligament is increased. Since the outer collateral ligament is strongly protected, it becomes easy to suppress the varus of the knee joint, so that the load stress on the inner side of the tibia is reduced, and the risk of developing a splint can be reduced.

<Support for other parts>
Part A is a part that applies the strongest tightening force (first tightening force) to the region corresponding to the position of the greater gluteus. And this A part and the B part which supports the thigh fascia intestinal muscle mentioned above are connected around the outer side of the muscular abdominal muscle of the gluteus medius. The thigh fascia enteric muscle is a muscle that acts on the hip internal rotation movement in an antagonistic manner with the hip abduction and external rotation of the sewing muscle. It is possible to control the hip internal rotation during walking. In this embodiment, when the A part supports the gluteus medius with the strongest tightening force, it is linked with the femoral fascia intestinal muscle to prevent hip abduction / inversion against the hip abduction / rotation of the sewing muscle The pivoting action works preferentially when kicking up the foot, making it easier to lift the foot straight.

  Part C is below the part A, that is, below the gluteal abdominal muscles of the coccyx (not shown) from No. 2 to No. 3, and in the region where the maximum extension force is required when tilting forward, 3 (tightening force 3). By supporting the lower part of the gluteal muscle with a medium tightening force, the gluteal muscle is easily exerted while the gluteal muscle is extended in the hip internal rotation position, so that the hip internal rotation movement can be controlled more easily.

  The portion H is a portion that applies a medium tightening force (third tightening force) to a region corresponding to the center position of the hamstring muscle (hamstrings) above the knee joint. By supporting the hamstring muscle with a medium tightening force, the lateral expansion of the hamstring muscle is allowed in the knee flexion position (squat), and the knee can be flexed smoothly.

  The F portion is a portion that applies the strongest tightening force (first tightening force) to a region corresponding to the position of the entire length of the thigh from the proximal pubic joint. That is, the F part descends along the running of the muscle from the pubic nodule, which is the attachment start position of the semi-tendon / hemimenoid muscle located inside the rear surface of the thigh, and the muscle abdomen A width that compensates for the entire width is provided, and the strongest tightening force is used to support a range where the inner side collateral ligament, which is the site of attachment from the muscle abdomen to the tendon, is compensated for the foot. By supporting the muscle tendon transition portion in the lower part of the semi-tendon / membranous muscle, the medial collateral ligament located on the side thereof can also be reinforced. Furthermore, since the Z portion and F portion that support the hip joint adductor muscle group with the strongest tightening force are connected on the inner side of the thigh, the hip adduction action can be efficiently assisted.

  The T portion is a portion that applies the strongest tightening force (first tightening force) to a region corresponding to the lower portion of the P portion and the Q portion and the upper upper side of the knee joint. The T part passes through the upper part of the patella located on the lower side of the front thigh from the lower third of the outer part of the thigh and is connected to the S part that supports the inner side of the knee including the inner part of the patella.

Further, the U portion is a portion that applies a medium tightening force (third tightening force) to the partial region inside the knee joint from the upper outside of the knee joint below the T portion. That is, the intermediate tightening force is used to support the position that passes above the patella and the region that covers the outside of the range in which the inner side of the patella is compensated for at the inner side of the knee joint. By setting the strongest tightening force obliquely from the upper side of the patella, that is, by setting the strongest tightening force obliquely, the movement of the patella to the outside can be suppressed. As a result, the knee joint is likely to be stable during knee flexion, and the quadriceps muscles are more likely to exert force.
