If the functional clothing of the present invention is worn, the explosive force of the lateral movement or the rotation action during tennis, volleyball, and basketball can be further improved.

The inventors of the present inventors have conducted repeated researches to improve the explosive force of a lateral movement or a rotation movement in sports such as tennis, volleyball, and basketball. It was found that based on the foot pressure and shear force of the side step, or the bending condition of the sole during lateral movement and back and forth movement, the long side direction became the predetermined direction on the front side of the socks and the front side of the rear feet. A plurality of anisotropic non-slip parts are set on the part, so that the explosive force of the lateral movement or rotation action during the movement is increased.

Specifically, the side steps in three items of tennis, volleyball, and basketball, which are representative of indoor sports, were studied. The testees were 3 experienced persons and 2 inexperienced persons, a total of 5 persons. The pressure distribution measurement system was used to analyze the foot pressure data of the three steps described above.

The socks according to one or more embodiments of the present invention can be used in combination with sports pants capable of tilting the pelvis forward (hereinafter simply referred to as "pelvic forward pants"). By using the socks and pelvic forward trousers in combination, the explosive power of lateral movement or rotation during tennis, volleyball, and basketball can be further improved.

The pelvic forward lean pants are not particularly limited, and examples include sports pants including a first cloth portion with strong tightness and a second cloth portion with weak tightness. The first cloth portion covers the pelvis and the lower portion. Around the body including the abdomen, the back is higher than the front, and the second cloth part with weak tightness is arranged below the first cloth part. The waist part is located on the upper end of the pants. The first cloth portion is formed, and the front surface of the belt portion is formed by the second cloth portion. With the above configuration, the sports pants are fastened around the body including the lower abdomen and the back of the waist. Furthermore, the pelvis can be tilted forward and the aforementioned pelvic tilt posture can be maintained. In addition, by arranging the second cloth portion having a weak tightness under the first cloth portion, the large movements of the gluteus maximus muscle and the lower abdomen including the crotch portion are not hindered.

In the above-mentioned sports pants, a third tight cloth portion may be arranged between the first cloth portion and the second cloth portion and continuous from both sides to the back to cover a part of the gluteal muscles. This will not hinder the larger movements of the gluteal muscles. This form is suitable for women. If it is for men, this part can also be set as the first cloth part with strong tightness.

It is preferable that the first cloth part is an elastic fabric containing elastic threads, and the second cloth part is an elastic knitted fabric including elastic threads. The fabric is thin, and the mass (mass per unit area) is lighter, and the stretching force (tightness) is also high, which is suitable for keeping the pelvis leaning forward. Knitted fabrics are suitable for keeping the muscles of the hips to the feet in a relaxed state and maintaining free movement.

The first cloth part is preferably a cloth part obtained by laminating two elastic fabrics containing elastic threads. If two pieces of elastic fabric are laminated, it can exhibit strong tightness. By containing elastic threads, it is easy to produce stretching, and it is easy to follow the movement of muscles caused by exercise.

The second cloth portion is preferably a stretch knitted fabric containing elastic threads. If it is a single knitted fabric, weak tightness tends to occur, and it will not hinder large movements of the gluteus maximus and the lower abdomen including the crotch.

The third cloth portion is preferably a stretch fabric containing elastic threads. The third cloth portion is arranged at a position covering a part of the gluteus gluteal muscle without interfering with a large movement of the gluteus gluteal muscle.

The elongation of each cloth part under a load of 17.6 N measured in accordance with JIS L 1096 is preferably: the elongation (S1) of the first cloth part is 20-30% in the longitudinal direction (corresponding to the height direction), and the transverse direction (corresponding to the body) (Width direction) 10 to 20%, the elongation (S2) of the second cloth part is 160 to 190% in the longitudinal direction and 70 to 100% in the transverse direction, and the elongation (S3) of the third cloth part is 30 to 60% in the longitudinal direction and 20 in the transverse direction. ~ 50%. However, it is a relationship of S1 ≦ S3 <S2 in the vertical direction.

The elongation of the first cloth portion may be changed in different regions. For example, in order to maintain the forward tilt of the pelvis and improve the wearing feeling, the elongation rate of the first cloth portion (for example, 302b and 302d shown in FIG. 7 described below) disposed at the central portion of the front and back is smaller than that of the front portion and the rear portion. The elongation of the first cloth portion (for example, 302a and 302c shown in FIG. 7 described below) on the side surface portion of the back surface may be sufficient. However, even in this case, there is a relationship of S1 ≦ S3 <S2 in the vertical direction.

The initial longitudinal elastic modulus of the first cloth part (the slope of the stress at the time of 5% elongation in the longitudinal direction) is preferably three times or more the initial longitudinal elastic modulus of the second cloth part. With this, the first cloth part can fasten the body around the lower abdomen and the back of the waist, so that the pelvis can be tilted forward, and the pelvis can be tilted forward. In addition, the second cloth portion does not hinder large movements of the gluteus maximus and the lower abdomen including the crotch.

The upper end of the back of the first cloth section is beyond the upper end of the pelvis. The front is located between the anterior superior sacral spine and the subcondylar, and the width of the first cloth section in the length direction (height direction) is wider than the front. ideal. Thereby, the forward tilt position of the pelvis can be more strongly maintained. In addition, since the upper end of the back surface of the first cloth portion is set to exceed the upper end of the pelvis, there is no case where the pants fall down due to the action during exercise.

It is preferable that the upper center part of the back surface is located at a position which is higher than the upper center part of the front side by more than 60 mm. More preferably, it is 80 mm or more. The upper limit is preferably 120 mm or less. Thereby, the forward tilt position of the pelvis can be more strongly maintained. Therefore, if the back and both sides of the waistband portion of the pants are formed by the first cloth portion and the second cloth portion is formed at the front, the central upper end portion of the back can be disposed higher than the upper central portion of the front.

The mass per unit area (mass per unit area) of the first cloth part is preferably 100 to 400 g / m ² , and more preferably 150 to 360 g / m ² . The mass per unit area of the second cloth portion is preferably 100 to 400 g / m ² , and more preferably 150 to 300 g / m ² . The mass per unit area of the third cloth portion is preferably 100 to 220 g / m ² , and more preferably 120 to 200 g / m ² . The first cloth portion may be used by laminating two third cloth portions. If the mass per unit area is in the above range, it is lightweight and suitable as sports pants.

The waistband portion at the upper end of the pants is provided with a waist elastic band at the front, and no waist elastic band may be provided at both sides and the back portion. With this, the elastic waistband of the front waist elastic band can be used to put on and take off pants, and there is no case of sliding down due to movement during exercise. Furthermore, a rope may be attached to the belt portion.

The length of the hem of the pants may extend below the lower part of the crotch, and may be a length of 2 to 100 cm from the lower part of the crotch.

The first cloth constituting the first cloth portion and the third cloth constituting the third cloth portion are preferably woven fabrics, and examples thereof include plain weave fabric, twill weave fabric, and satin weave fabric. The second cloth constituting the second cloth portion is preferably a knitted fabric, and includes, for example, a circular knitted fabric, a horizontal knitted fabric, a longitudinal knitted fabric (including Tricot fabric, Raschel knitted fabric), and a loop knitted fabric. , There are jersey, jersey, rib knit, double knit (double knit), rib knit, double back knit, warp knitting, warp knitting, warp knitting satin weaving, chain knitting, Lining structure and so on. The fibers used in the first to third cloths are preferably polyethylene terephthalate (polyester) fiber threads, polyethylene terephthalate (polyester) spinning threads, nylon fiber threads, nylon spinning threads, Polyurethane fiber thread (elastic thread) or a combination of these. It can also be made of a covered wire made by winding non-elastic wires around the elastic wires. The first cloth, the second cloth, and the third cloth are sewed to form a first cloth portion, a second cloth portion, and a third cloth portion, respectively, to constitute pants.

The effect of pelvic support is that if the pelvis is tilted forward, the position of the center of gravity is forward, and the center of the foot pressure becomes the direction of the toe. In addition, in a static posture, although the position of the center of gravity changes when the pelvis is tilted backward, located in the middle position, and leaned forward, the upper body can be tilted forward without bending the back bone. As a result, with the pelvis leaning forward, it is difficult for the legs to lift forward and upward, the kicking of the foot diagonally rearward becomes larger, and the maximum stretchable movable area of the foot swinging back becomes larger. In addition, the opposite effect of kicking obliquely downwards causes the maximum extension of the hip joint, and its influence causes rapid contraction of muscles such as the psoas major. The psoas major is good at stretching muscles (extensible contraction) while exerting maximum performance (force) at that moment. Therefore, the aforementioned sports pants can tilt the pelvis forward, thereby promoting various movements such as straight movement, rotation, and lateral movement of muscles.

Hereinafter, the sports pants will be described using drawings. In the following drawings, the same symbol represents the same thing. Fig. 7 is a schematic diagram of an example of sports pants, (a) is a front view, (b) is a side view, and (c) is a rear view. In the sports pants 301, the first cloth parts 302a, 302b, 302c, and 302d having strong tightness cover the periphery of the body including the pelvis and the lower abdomen.
