  The socks of one or more embodiments of the present invention can be used in combination with sports pants that allow the pelvis to lean forward (hereinafter also simply referred to as “pelvis forward lean pants”). By using the socks and the pelvis tilted pants together, it is possible to further increase the instantaneous force of lateral movement and rotational movement during exercise such as tennis, volleyball, and basketball.

  The pelvic anteversion pants are not particularly limited, but include, for example, a first tight fabric portion and a weak tight second fabric portion, and the first fabric portion includes a pelvis and a lower abdominal region Cover, and the back is higher than the front, the second cloth part of the weak tightening is arranged in the lower part of the first cloth part, the upper end of the pants has the belt part, An example is sports pants in which the back surface and both side surfaces are formed of the first cloth portion and the front surface of the belt portion is formed of the second cloth portion. With the above-described configuration, the sports pants tighten around the body including the lower abdomen and the back of the waist. Furthermore, the pelvis can be tilted forward to maintain the pelvis in a forward tilted posture. In addition, since the weakly tightened second cloth portion is arranged below the first cloth portion, large movements of the lower abdomen including the gluteus maximus and the crotch are not hindered.

  In the above sports pants, a third fabric having a middle tension between the first fabric portion and the second fabric portion, which is continuous from both side surfaces to the back surface and covers a part of the gluteus medius muscle. Parts may be arranged. This does not prevent large movements of the gluteus medius. Such a form is suitable for women, and for men, this portion may also be the first fabric portion having a high tightness.

  It is preferable that the first fabric portion is a stretch woven fabric including elastic yarns and the second fabric portion is a stretch knitted fabric including elastic yarns. The woven fabric is thin, has a light weight (weight), has high stretch power (tightness), and is suitable for keeping the pelvis in a forward leaning posture. The knitted fabric is suitable for keeping the muscles from the buttocks to the legs in a free state and keeping free movement.

  It is preferable that the first fabric portion is a fabric portion in which two stretch fabrics including elastic yarns are laminated. You can get strong tightness by stacking two stretch fabrics. By including elastic threads, it is easy to stretch and follow the movement of muscles during sports.

  The second fabric portion is preferably one stretch knit fabric including elastic yarn. With a single knit, it is easy to give a weak tightness, and it does not interfere with the large movements of the lower abdomen including the gluteus maximus and the crotch.

  The third fabric portion is preferably one stretch woven fabric including elastic yarn. By arranging the third dough part at a position that covers a part of the gluteus medius, it does not prevent large movements of the gluteus medius.

  The elongation rate of each fabric part under a load of 17.6 N measured according to JIS L 1096 is such that the elongation rate (S1) of the first fabric part is 20 to 30% in the vertical direction (corresponding to the height direction), and the horizontal direction. (Corresponding to the width direction of the body.) 10 to 20%, the elongation rate of the second fabric portion (S2) is 160 to 190% in the vertical direction, 70 to 100% in the horizontal direction, and the elongation rate of the third fabric portion (S3). Is preferably 30 to 60% in the vertical direction and 20 to 50% in the horizontal direction. However, there is a relationship of S1 ≦ S3 <S2 in the vertical direction.

  In addition, the expansion rate of the first fabric portion may be changed in different regions. For example, for the purpose of improving the wearing feeling while keeping the pelvis leaning forward, the extension of the first fabric parts (for example, 302b and 302d shown in FIG. 7, which will be described later) arranged in the central parts of the front surface and the back surface. The rate may be smaller than the extension rate of the first cloth portions (for example, 302a and 302c shown in FIG. 7 described later) arranged on the front and back side surfaces. However, even in this case, there is a relationship of S, 1 ≦ S3 <S2 in the vertical direction.

  The initial longitudinal elastic modulus of the first fabric portion (slope of stress at 5% elongation in the vertical direction) is preferably three times or more the initial longitudinal elastic modulus of the second fabric portion. As a result, the first fabric portion can tighten the periphery of the body including the lower abdomen and the back of the waist, tilt the pelvis forward, and maintain the forward tilted posture of the pelvis. In addition, the second fabric portion does not hinder a large movement of the lower abdomen including the gluteus maximus and the crotch.

  The upper end of the back surface of the first cloth part is above the upper end of the pelvis, the front surface is located between the superior anterior iliac spine and the crotch, and the width of the first cloth part in the body length direction (height direction) is The back side is preferably wider than the front side. As a result, it is possible to more strongly maintain the forward tilted posture of the pelvis. Further, since the upper end of the back surface of the first fabric portion is located above the upper end of the pelvis, the pants do not slide down due to movement during sports.

  It is preferable that the back central upper end of the first dough portion is higher than the front central upper end by more than 60 mm. More preferably, it is 80 mm or more. The upper limit is preferably 120 mm or less. This makes it possible to maintain the pelvic leaning posture more strongly. For this reason, if the back and both sides of the belt portion at the upper end of the pants are formed of the first cloth portion and the front surface is formed of the second cloth portion, the back center upper end is positioned higher than the front center upper end. Can be placed.

The mass (unit weight) per unit area of the first dough portion is preferably 100 to 400 g / m ² , and more preferably 150 to 360 g / m ² . The basis weight of the second fabric portion is preferably 100 to 400 g / m ² , and more preferably 150 to 300 g / m ² . The basis weight of the third fabric portion is preferably 100 to 220 g / m ² , and more preferably 120 to 200 g / m ² . The first fabric part may be used by laminating two third fabric parts. When the basis weight is within the above range, the weight is within the above range, which is suitable for sports pants.

  The waist rubber may be arranged on the front surface of the belt portion at the upper end of the pants, and the waist rubber may not be arranged on both side surfaces and the back surface. As a result, the elasticity of the waist rubber on the front allows the pants to be attached and removed, and does not slide down due to movement during sports. A string may be attached to the belt portion.

  The length of the hem of the pants is only required to extend below the crotch part, and may be 2 to 100 cm downward from the crotch part.

  The first fabric forming the first fabric portion and the third fabric forming the third fabric portion are preferably woven fabrics such as plain weave, twill weave, and satin weave. The second fabric forming the second fabric portion is preferably a knit, and includes, for example, circular knitting, horizontal knitting, vertical knitting (including tricot knitting and Russell knitting), pile knitting, etc., flat knitting, plain knitting, rib Knitting, smooth knitting (double-sided knitting), rubber knitting, pearl knitting, denby structure, cord structure, atlas structure, chain structure, insertion structure, and the like. The fibers used for the first to third fabrics are preferably polyethylene terephthalate (polyester) filament yarn, spun yarn, nylon filament yarn, spun yarn, polyurethane filament yarn (elastic yarn), or a combination thereof. It may be a covering yarn in which a non-elastic yarn is wound around the elastic yarn. The first cloth, the second cloth, and the third cloth are sewn to become a first cloth part, a second cloth part, and a third cloth part, respectively, and form pants.

  The effect of the pelvic support is that when the pelvis is tilted forward, the position of the center of gravity comes to the front and the center of foot pressure comes to the toe direction. Further, when the pelvis is tilted backward, in the middle, or forward in a static posture, the center of gravity changes, but the upper body can be tilted forward without bending the spine. As a result, the pelvis leans forward, making it difficult for the thigh to rise to the upper front, increasing the kicking of the leg diagonally rearward, and increasing the maximum range of extension for swinging the leg backward. In addition, the reaction of kicking diagonally downward causes maximum extension of the hip joint, which causes muscles such as the psoas major to contract rapidly. The psoas muscle is a muscle that is good at exerting power while being stretched (stretchable contraction), and exerts its maximum performance (strength) at this moment. Therefore, in the sports pants, the pelvis can be tilted forward to promote various movements such as straight movement, rotation, and lateral movement of muscles.
