Description

  The present invention relates to exercise spats (hereinafter also simply referred to as spats) worn in a state of being in close contact with the surface of the wearer's lower body. For example, the abrupt direction change operation frequently seen in ball games and the like is provided. In such a case, the present invention relates to an exercise spat that supports a posture in a state where the body is bent deeply and assists a direction change operation.

  Conventionally, as for exercise spats, various tights and spats for the purpose of improving exercise functionality and protecting muscles and joints are known.

  The lower limb protective clothing of Patent Document 1 below is a clothing made of an elastic fabric having a lower body portion having a leg portion with a length exceeding the patella portion, and the clothing partly has a strong tightening force. A portion having a strong tightening force, passing through the greater trochanter from at least the greater trochanter, and further on the vicinity of the boundary between the biceps femoris and the intestinal shin ligament to support the biceps femoris With a protective apparel for the lower limbs that has a strong tightening force section that crosses the vicinity of the tendon of the lower part of the biceps femoris muscle diagonally and reaches the upper end of the tibia without crossing the biceps femoris is there. This protective clothing for the lower limbs can protect the lower leg during various sports such as baseball, rugby, soccer, etc., especially by supporting the hamstrings that are the muscles on the back of the thigh, while maintaining the balance of the muscles, Its purpose is to provide protection and movement support for the entire joint and hip joint.

  The exercise spats of the following Patent Document 2 are exercise spats in which a main component portion is formed of a stretch material and is worn in a state of being in close contact with the surface of the lower body of the wearer, and includes a strongly tightened material and a weakly tightened material. Thus, the material of strong tightening is disposed at a position covering at least a part or all of both large gluteal muscles, and the material of weak tightening is disposed in a region other than the region where the material of strong tightening is disposed. This makes it possible to achieve exercise spats that assist in contracting the greater gluteal muscles when kicking the ground with your feet and moving forward when you need a momentary force, such as running motion, and exert a stronger momentary force. Yes.

Japanese Patent No. 3012819 JP 2005-146450 A

However, the lower limb protective clothing of Patent Document 1 supports hamstrings, which are muscles on the back of the thigh, to maintain the balance of the muscles and to protect the knee joint and the entire hip joint and assist the work. The main feature is that the spats for exercise of Patent Document 2 assist the contraction of the greater gluteal muscle when moving forward by kicking the ground with a foot, for example, athletics, especially in a short distance running motion. This is the main function. These are intended for exercise support by the waist, joint protection, and material placement methods during exercise, but support the posture of bending the body deeply, for example, in the case of a sudden turning movement often seen in ball games, It does not have a function to assist the direction change operation.
Accordingly, the present invention provides an exercise spat that solves the problems of the prior art and supports a posture in which the body is bent down deeply and enhances the direction change operation in a sport in which a rapid direction change operation is frequently performed. For the purpose.

The exercise spats of the present invention are made of stretch material, and are worn in a state of being in close contact with the surface of the lower body of the wearer, and include the first type material and the second type material. It is spats, and the tightening force of the first type material (also referred to as a strong tightening material in the present specification) is the tightening force of the second type material (also referred to as a weak tightening material in the present specification). The first type of material is disposed at a position including a region covering at least a part of the region extending from both the left and right great gluteus muscles to the hamstrings, and the second type of material is The exercise spats are arranged in a region other than a central region and a region where the first type material is disposed.
Furthermore, it is also possible to arrange the first type of material in an area covering at least a part or all of the left and right middle incisors.

In the first type of material, the circumferential length of the region covering the greater gluteal muscle is L1, the circumferential length of the region covering the vicinity of the greater trochanter is L2, and the circumference of the region covering the hamstrings. When the length in the direction is L3, it is preferable that L2 <L1 <L3, L2 is in the range of 30% to 70% of L1, and L2 is in the range of 10% to 40% of L3.
Further, the boundary between the first type material and the second type material from the waist part to the leg part on the back side of the spats is convex at the center side of the spats body part in the greater gluteal muscle region. In the lower gluteal muscle lower region, a convex shape can be formed on the side line side of the spats main body, and in the hamstring region, a convex shape can be formed on the front side of the inner thigh of the thigh.
The region where the above-described strong tightening material is disposed is basically bilaterally symmetric, but may be bilaterally asymmetrical as necessary.

  In the present invention, a strong tightening material is disposed in close contact with a region covering at least a part of the human body from at least left and right greater gluteal muscles to hamstrings. When the direction of travel is changed by bending the body deeply as in the direction change operation, the tension of the material generated by stretching the tightly tightened material supports the posture and assists the direction change operation.

  Embodiments of the present invention will be described below. First, the movement operation assisted by the exercise spats of the present invention will be described. The rapid direction change operation frequently seen in ball games and the like is roughly divided into three types: a movement operation in the initial movement direction, an operation of decelerating once to change the direction, and a movement operation in the target movement direction. .

  The above operation will be described with reference to FIG. 4 is a direction change operation from the right direction to the left direction toward the traveling direction (forward direction) X. FIG. 4A is a movement operation in the initial movement direction (right direction) of the human 90, FIG. 4B shows an operation in which the human 90 once decelerates and changes its direction, and FIG. 4C shows a movement operation in the intended movement direction (left direction) of the human 90.

  During the operation of changing the direction, each joint of the lower body on the side of the stepped-on leg (right leg 91 in FIG. 4) exhibits particularly large power, and muscles such as the gluteal muscle contract and exert a large force. At this time, since the hip joint is deeply bent, the skin of the region 92 from the buttocks to the back of the thigh is greatly stretched.

  As shown in FIG. 4B, in order to stabilize the posture at the time of turning, the gluteal muscles that have the function of extending the hip joint contract while being stretched, but if the function is weak, the posture is sufficiently retained Sometimes you can't do it and you fall. For this reason, when there is not enough muscular strength, the body cannot be bent deeply so as not to fall, and as a result, a quick turning operation cannot be performed.

  Therefore, by placing a strong tightening material on the part from the buttocks to the back of the thigh, the tension exerted by the stretched material following the skin extension when the hip joint is bent deeply supports the posture of the wearer. As a result, the direction change operation is assisted.

  Next, the muscles of the lower half of the human body will be described with reference to FIG. The large gluteal muscle 80 exists in the buttock, and the gluteal muscle 82 exists in the outer surface region from above. Further, the hamstrings 81 (hamstrings 81 is composed of a group of muscles including the biceps femoris 81a, the biceps femoris short head 81b, the semi-tendon-like muscle 81c, and the semi-membranous muscle 81d) on the rear surface of the thigh. is doing. In the exercise spats of the present invention, a strong tightening material is disposed in a region extending from the large ankle muscle 80 to the hamstrings 81 or in an area extending from the large ankle muscle 80 and the middle ankle muscle 82 to the hamstrings 81. By arranging a high-power fabric material in this region, it is possible to effectively assist muscle contraction in the above-described operation.

  When the hip joint is bent during the direction change operation, the greater masseter muscle of the stepped leg contracts while being stretched, and in order to prevent the fall due to excessive bending of the hip joint and to perform a smooth direction change operation, Demonstrates the main force of movement in the extension direction. Therefore, by placing a strong tightening material on the greater gluteal muscle part, the tightening force of the strong tightening material not only helps the contraction of the greater gluteus muscle, but also prevents the hip joint from overturning due to excessive bending, and also smoothly changes direction. Is possible. In this case, in order to obtain the above-mentioned effect, it is necessary to cover at least the muscle abdominal part (central part of the muscle) of the greater ankle muscle, and in order to obtain a sufficient effect, the entire greater ankle muscle should be covered. It is preferable to dispose a strong tightening material.

  In addition, the middle gluteus muscle is located on the outer surface of the iliac, and acts to prevent the body from falling outward by exerting a force in the hip abduction direction when the hip joint is bent during the direction change operation. Therefore, by arranging the strong tightening material in the middle gluteal muscle portion, the tightening force of the strong tightening material assists the contraction of the gluteus medius and can prevent the body posture from falling outward when it is stepped on. In this case, in order to obtain the above effect, it is necessary to cover at least the abdominal part of the middle gluteal muscle, and in order to obtain a sufficient effect, a strong tightening material is disposed so as to cover the entire middle gluteal muscle. It is preferable to do. In the above-mentioned direction changing operation, the greater gluteal muscle part of the strong tightening material assists the extension of the hip joint, and the intermediate gluteal muscle part assists the abduction of the hip joint.

  The hamstrings are a group of muscles that extend the hip joint together with the great gluteus muscle, and perform the same function as that of the great gluteus muscle even when the direction is changed. Therefore, by arranging the strong tightening material in the hamstring portion, it is possible to assist the extension of the hip joint together with the greater gluteal muscle portion. In this case, in order to achieve the above-mentioned assistance, at least the muscle abdominal portion of the hamstrings (more specifically, the biceps femoris, the half tendon-like muscle, and the half-membranous muscle constituting the hamstrings) In order to obtain a sufficient auxiliary effect, it is preferable to arrange a strong tightening material so as to cover the entire hamstrings. The purpose of the present invention is to prevent the fall due to excessive bending of the hip joint and assist in smooth direction change operation, so a series of strong tightening materials covering the greater gluteal muscles and hamstrings that work similarly to the hip joint It is preferable to form.

  FIG. 3 is a development view of members composed of a strong tightening material A disposed in a portion from the left buttock to the left thigh rear surface in an exercise spat of an example described later. In this member, the circumferential length of the region covering the greater gluteal muscle is L1, the circumferential length of the region covering the vicinity of the greater trochanter is L2, and the circumferential length of the region covering the hamstrings is L3. When L2 <L1 <L3, L2 is preferably in the range of 30% to 70% of L1, and L2 is preferably in the range of 10% to 40% of L3. Here, L1 is the maximum value of the circumferential length of the region covering the greater gluteal muscle (the length from the side line side end of the spats to the buttock center side end), and L2 is the circumference of the region covering the vicinity of the greater trochanter. L3 is the minimum value of the length in the direction (length from the side line side end to the center side end near the greater trochanter), L3 is the circumferential length of the region covering the hamstrings (from the side line side end to the large This is the maximum value of the length of the thigh to the inner crotch end. In the present invention, the vicinity of the greater trochanter refers to a region in the range of 5 cm in the vertical direction around the greater trochanter. Moreover, L2 can also be arrange | positioned in the position equidistant from L1 and L3.

When L2 is 70% or more of L1 and / or 40% or more of L3, the region covered with the strong tightening material becomes excessive, which hinders operations other than the direction change operation. In other words, considering the assistance of the leg that the wearer has stepped in when turning the direction, the value of L2 is better, but if it exceeds the above range, the tightening area of the buttocks becomes larger than necessary. It becomes difficult to raise the knee in running motion. However, in the present invention, by setting L2 within the above range and shortening L2 as compared with L1 and L3, the vicinity of the greater trochanter is covered with the weak tightening material, and such a problem does not occur.
The present invention is also intended to assist in the longitudinal extension from the greater gluteus to the hamstrings. Therefore, when L2 is 30% or less of L1 and / or 10% or less of L3, the region of the L2 portion becomes thin. Therefore, the assistance by the strong tightening material becomes insufficient.
Therefore, if the lengths L1, L2, and L3 are set so as to be within the above range, it is possible to sufficiently assist the leg that has been stepped on during the direction change operation without hindering the movement of raising the knee. Become.

  As shown in FIG. 3, the boundary between the strong tightening material and the weak tightening type material from the waist part to the leg part on the back of the spats has a convex shape on the center side of the spats in the greater gluteal region. The area near the greater trochanter at the lower part of the greater gluteal muscle has a convex shape on the side line side of the spats, and the hamstring area has a convex shape on the front side of the inner crotch. Can follow and extend, and can suppress the pull-in.

  Further, the weak tightening material is disposed in a region other than the central region of the buttock and the region where the strong tightening material is disposed. At the time of turning, the weight of the stepped-on leg rides, the skin in the region from the buttocks to the back of the thigh greatly expands, and the corresponding part of the exercise spats also expands greatly. At this time, if the strong tightening materials arranged in the left and right large gluteal muscles are connected in the middle so that they are in a series of left and right, the opposite leg is also pulled to the leg stepped on by the strong tightening material, and the stepped-in leg It is conceivable that the center of gravity moves to the side and falls. However, in the present invention, the strong tightening material that covers the left and right large gluteal muscles is divided into left and right members by the weak tightening material disposed in the center region of the buttocks, so that the opposite leg is pulled to the depressed leg side. There is no such thing, and the above-mentioned problems do not occur.

  The spats for exercise of the present invention are suitable for a ball game sport having a lot of rapid direction change operations.

  In the present invention, in order to create an “almost close contact” state, the peripheral direction is 50% or more and 110% or less, more preferably 70% or more and 95% or less, and the length is 75% or more and 100% with respect to the naked size of the human body. % Or less, more preferably 85% or more and 100% or less to form exercise spats. Of course, since the size of the human body varies among individuals, the above ratio is a guide.

  In the present invention, the “main component” refers to a main fabric portion constituting the exercise spats, that is, a fabric covering the waist and at least the thigh. In addition, the strong tightening material is disposed in a region that covers at least a part of or all of the parts from both greater calf muscles to the hamstrings. Furthermore, you may arrange | position to the area | region which covers at least one part of the middle ankle.

  The exercise spats may be formed to cover up to the knee, below the knee, or to the ankle. In the case of covering up to the knee or ankle, the fabrics in those areas are arbitrarily arranged with a strong tightening material, a weak tightening material and / or a third fabric material as necessary.

  The strong tightening material and the weak tightening material are preferably integrated by sewing. However, in the case of a weft knitted fabric, it can be integrally knitted as will be described later.

  The strong tightening material and the weak tightening material of the present invention are stretch materials, and the elongation rate when the material is 4.9 N (500 gf) in a width of 5 cm is the first type at least in the longitudinal direction when used as spats. This material is preferably in the range of 5% or more and less than 30%, and the second type material is preferably in the range of 30% or more. In addition, when the elongation rate at 17.7 N (1800 gf) weight in a width of 5 cm is set to A when the value of the first type material is B and the value of the second type material is B, it is at least vertical. In the direction, A is preferably 30% or more and less than 80%, and B is preferably 80% or more.

In order to obtain such stretch characteristics of each portion, as will be described later, for example, when an elastic yarn is used as a constituent yarn of a knitted fabric or a woven fabric, the following means can be taken as an example.
(1) The composition ratio of the elastic yarn is made higher in the strong tightening material than in the weak tightening material.
(2) Increase the fineness of the elastic yarn in the strong tightening material compared to the weak tightening material.
(3) In the case of a woven fabric, the warp and / or weft density is increased, and in the case of a knitted fabric, the knitting density is increased as compared with a weak tightening material.
(4) A woven fabric or a knitted fabric is produced with a high tension material having a higher tension of the elastic yarn than a weak tension material.
(5) Fabrics or knitted fabrics are manufactured by making the fabric thicker than the weakly tightened material.

  The stretch material of the present invention is preferably at least one fabric selected from a 2-way stretch knitted fabric and a 2-way stretch woven fabric that expand and contract in the machine direction and the transverse direction.

  The two-way stretch knitted fabric or woven fabric may include polyester fiber yarns and elastic yarns as main component constituent yarns, or nylon fiber yarns and elastic yarns as main component constituent yarns. As another configuration, cotton (cotton) and elastic yarn may be used as the main component constituting yarn. Here, the main component constituting yarn means that the total of both components is 80% by weight or more. When polyester fiber yarn is used, it is easy to dry even with sweat. When nylon fiber yarn is used, the knitted fabric has a soft touch.

  The knitted or woven fabric may have any structure. As the woven fabric, a plain weave, a diagonal weave, and a satin weave, which are generally well known, may be a changed weave. Further, a knitted fabric knitted by a Russell warp knitting machine generally well known as a knitted fabric, a knitted fabric knitted by a tricot warp knitting machine, a knitted fabric knitted by a knit weft knitting machine, or the like may be used. For example, a knitted fabric having a half structure knitted by a tricot warp knitting machine or a knitted fabric having a power net structure knitted by a Russell warp knitting machine can be used. As the knitted weft knitted fabric, any structure such as a flat knitting (tengu knitting), a rubber knitting, a pearl knitting, and a smooth knitting (double-side knitting) may be used. The knitted fabric knitted by the knit weft knitting machine may be a knitted fabric knitted by a circular knitting machine or a flat knitting machine. In the case of the weft knit, it is also possible to integrally knitting the weak tightening material and the strong tightening material without requiring sewing. For example, there is an apparatus called “FIRST-X” of a flat knitting machine (Shimae Seiki Seisakusho), which can be used to knit the waist and both legs at the same time to produce a knitted product without sewing.

  In addition, a combination of strong and weak tightening materials is seamlessly knitted into a cylindrical shape with a device called "seamless body inner knitting machine" under full computer control of Santoni, Italy. It is also possible to do.

  The woven fabric or knitted fabric preferably uses at least a part of elastic yarn having elasticity such as polyurethane yarn.

  The elastic yarn is preferably at least one selected from a polyurethane elastic yarn and a polyester elastic yarn. This is because it is highly stretchable and suitable for sports clothing. The elastic yarn may be either a bare yarn (bare yarn) or a covered yarn whose surface is coated with polyester fiber or nylon fiber.

  A fabric using a high crimped false twisted yarn such as polyester or nylon which has been subjected to high crimped false twisting to give stretchability is also possible for at least part or all of the fabric. It is also possible to simply use a plurality of the stretchable knits. Furthermore, the stretchable knitted fabric is laminated into a two-layer laminate fabric, and a stretchable polyurethane sheet is sandwiched between the stretchable knitted fabric and laminated into three layers. A layer laminate fabric can also be used.

  Next, as a method of giving the fabric material a “strong” or “tight” tightening force to obtain a strong tightening material and a weak tightening material, a mixture ratio of polyurethane yarn and high crimped false twisted yarn (hereinafter referred to as stretch yarn) is used. The “large” and “small” of each can give the fabric material a “strength” tightening force. As a method of changing the blend ratio, changing the thickness of the stretch yarn to “thin and thin” gives the blend ratio “large” or “small”. There is a way to get a “large” or “small” mix ratio. It is also possible to change the knitting density to “sparse / dense” when the mixing ratio of the stretchable yarn is constant. In addition, using a fabric with different types of stretch yarns, using a laminated fabric and a non-laminated fabric, or changing the number of layers of the same fabric will also give the fabric a “strength” tightening force. It is possible to have it.

  The “strength” tightening force of the strong tightening material and the weak tightening material can be confirmed by the magnitude of the stretch rate of the fabric at a constant load. That is, a fabric having a strong tightening force has a low elongation rate, and a fabric having a weak tightening force has a high elongation rate.

  In the present invention, the tightening force refers to the resistance of the material to elongation.

  The measuring method of the stretch ratio representing the stretchability and the tightening force is a TENSILON universal type tensile tester (UTM-III-200, manufactured by Toyo Baldwin), the tensile strength is 20 cm / min, and the size of the sample fabric is The width was 5 cm, the length was 30 cm, and the holding interval was 20 cm. The weight for measuring the tightening force was 4.9 N (500 gf), the weight for measuring the stretch property was 17.7 N (1800 gf), and the measurement was made in the direction of the background of the fabric material. The stretch ratio used in the description of the present invention is a measurement result by this measurement method.

  In the exercise spats according to the present invention, the strong tightening material and the weak tightening material may be integrated by sewing or bonding to form the exercise spats.

  Examples of sewing methods include lock stitching, chain stitching, 1-needle overlock, 2-needle overlock, sewing with a sewing machine that forms a seam, etc. It is not limited to these. However, it is desirable to adopt a one-needle overlock, a two-sewing overlock, and a flat seamer that have a stretch property and are less likely to cause discomfort when worn.

  As the bonding method, paste two types of fabrics (members) that you want to integrate, melt them with heat, and paste them with a heat-meltable seam tape made of resin, such as polyurethane or silicone, which penetrates and solidifies after cooling. Although there is a thermocompression bonding method in which the fabric can be bonded by sandwiching between the fabrics and heat-pressing, it is desirable to provide a stretch property similar to sewing so as to eliminate the uncomfortable feeling at the time of wearing.

  The exercise spats of the present invention are suitable for various sports such as tennis, badminton, squash, hockey, soccer, rugby and the like.

  Hereinafter, embodiments of the exercise spats according to the present invention will be described with reference to FIGS. 1 and 2. Fig.1 (a) is a front view of the exercise spats of a present Example, FIG.1 (b) is a back view similarly. 2A is a left side view, and FIG. 2B is a view showing an inner crotch portion of the right thigh of the spats (a portion other than the inner crotch portion is indicated by a one-dot chain line). FIG. 3 is a development view of a strong tightening material disposed in a portion from the buttocks to the rear thigh in the present embodiment. The exercise spats 1 according to the present embodiment are configured by the members of the center front portion 1a, the front thigh portion 1b, the heel portion 1c, the rear center portion 1d, the back thigh portion 1e, and the waist strap 10 used at the time of wearing. did. The respective members are arranged symmetrically. In this embodiment, the members are integrated with each other by sewing to form the exercise spats 1. As a sewing method, a flat seam sewing machine was used, polyester spun-like filament yarns were used as needle yarns, wooly nylon yarns were used as upper and lower yarns, and stitched with flat seams. In addition, each member of an Example can also form one member by several parts, and can also form several members collectively in one part.

  The rear thigh portion 1e is composed of a strong tightening material A (indicated by a hatched portion in the figure), and is arranged in a region covering almost the entire region of the wearer's major and middle gluteal muscles and the hamstrings belly. When the length in the circumferential direction of the region covering the greater gluteal muscle is L1, the length in the circumferential direction of the region covering the vicinity of the greater trochanter is L2, and the length in the circumferential direction of the region covering the hamstrings is L3. : L2: L3 ratio is 2: 1: 4. In addition, the boundary between the strong tightening material and the weak tightening material from the waist to the leg under the back of the spats has a convex shape on the center side of the spats, and the lower part of the greater gluteal muscle is on the side line side of the spats The hamstring region has a convex shape on the front side of the inner crotch.

As the strong tightening material A, a polyester filament double yarn having a fineness of 136 dtex and a bare tenac structure using a polyurethane bare yarn having a fineness of 64 dtex, the mixing ratio is 85% by weight of polyester and 15% by weight of polyurethane. A circular knitting machine with a gauge number of 30 G was used. The elongation at the time of 4.9N (500 gf) load representing the tightening force was 20% in the warp direction and 25% in the weft direction. The elongation at the time of 17.7N (1800 gf) load representing the stretchability was 60% in the warp direction and 70% in the weft direction. The weight (unit weight) per unit area was 320 g / m ² .

The central front portion 1a, the front thigh portion 1b, and the rear central portion 1d other than the region where the strong tightening material A is arranged are composed of the weak tightening material B. As the weak tightening material B, a polyester filament yarn having a fineness of 68 dtex and a bare tenac structure using a polyurethane bare yarn having a fineness of 36 dtex, the mixing ratio is 85% polyester, 15% polyurethane, A circular knitting machine with a gauge number of 30 G was used. The elongation at the time of 4.9N (500 gf) load representing the tightening force was 90% in the warp direction and 70% in the weft direction. The elongation at the time of 17.7N (1800 gf) load representing the stretchability was 190% in the warp direction and 80% in the weft direction. The weight (unit weight) per unit area was 190 g / m ² . The heel portion 1c is made of a mesh material.

  In this example, in order to create a “substantially close contact” state, 80% in the peripheral direction and 90 to 95% in length were prepared as a guide for the naked size of the human body.

  Next, in order to verify the effect of the present example, the following experiment was performed on five ball players (two soccer players, two basketball players, and one rugby player).

  That is, the amount of lower limb muscle activity obtained from the measurement of the lower limb electromyogram during the step operation in the left-right direction is the same as that of the example product of the present invention and the comparative example product (the same shape as this example, and all parts are made of weakly tightened material). Comparison was made using a conventional trunks-type pants. The step operation referred to here is an operation of repeatedly stepping leftward with the right leg and rightward with the left leg, and the left and right legs are not grounded at the same time. The step speed at this time was 70% of the maximum step speed of each subject measured in advance for 10 seconds, and the average of five subjects was 103.5 times / minute. The step width per step was 100 cm for all members, and the measurement time was 20 seconds.

  The electromyograms of the lower limbs are derived from the outer front of the thigh, the inner front of the thigh, the inner front of the thigh, Measurement was performed by attaching electrodes to the center of the back of the thigh, the center of the buttocks, and the outside of the buttocks.

  All measurements were performed on the right leg, and the integrated value of the electromyogram while the right leg was grounded was defined as the amount of muscle activity. In addition, about 15-20 times of the electromyogram at the time of grounding is obtained during the measurement for 20 seconds, but these data were added and averaged within each subject, and it was set as the representative value of each subject. If there is an effect of the present embodiment, the amount of muscle activity when the present embodiment is worn should be low even if exercising at the same step speed.

  As a result, as shown in FIG. 5, when comparing the amount of muscle activity when wearing the conventional general trunks-type pants as 100%, the present embodiment is a comparative example product and the conventional general The muscle activity amount was lower than that of any conventional trunks-type pants, and the muscle activity amount was 90.0% lower than that of the conventional general trunks-type pants, particularly in the buttocks. FIG. 5 shows an average value of five subjects.

  From this result, it is clear that the strong tightening portion arranged from the heel portion to the hamstring in this embodiment assists the step operation. Moreover, although this result is a comparison of the amount of muscular activity in the same exercise intensity, it can be expected that a quicker step motion can be achieved if the muscle activity equivalent to that at the time of wearing the game pants is exhibited when wearing this embodiment. .

  Furthermore, when all subjects wear, there is less fatigue, and when changing direction from right to left or from left to right, assists in contraction of the greater gluteus and hamstrings when bending the body deeper, It was confirmed that the direction could be changed quickly and smoothly. The feeling of wearing was also well received.

  In the above-described embodiment, the spats are formed by the members of the center front portion 1a, the front thigh portion 1b, the heel portion 1c, the rear center portion 1d, the back thigh portion 1e, and the waist strap 10 used at the time of wearing. As long as the cloth material of each tightening force is arranged, the shape of each member is not limited to the shape of the above-described embodiment. Further, in the above-described embodiment, the length of the exercise spats is the length up to the above-knee position, but of course it is not limited to this, and the position below the knee is within the range in which the object of the present invention is achieved.
