[Problems to be Solved by Invention]

However, the trousers proposed in the above-mentioned patent documents have a low tightening force around the body including the lower abdomen and the back of the waist, and the conventional tights also tighten the thighs, so it is difficult to tighten only the above-mentioned body circumference. tie up.

In order to solve the above-mentioned conventional problems, the present invention provides sports pants that can tighten only the circumference of the body including the lower abdomen and the back of the waist, and can tilt the pelvis forward. [Technical means to solve problems]

The sports trousers of the present invention comprise a first fabric portion with strong fastening and a second fabric portion with weak fastening, wherein the first fabric portion covers the circumference of the body including the pelvis and lower abdomen, The back is located at a position higher than the front, a second fabric part with weak fastening is arranged on the lower part of the first fabric part, a waistband part is arranged on the upper end of the trousers, and the back and both sides of the waistband part are tied by the first fabric part The front surface of the waistband portion is formed by the second cloth portion. [Effect of invention]

The present invention can provide sports pants comprising a first fabric portion with strong fastening properties and a second fabric portion with weak fastening properties, wherein the first fabric portion covers the circumference of the body including the pelvis and lower abdomen , the back is located at a position higher than the front, the lower part of the first cloth part is arranged with a second cloth part with weak fastening, and the upper end of the pants is provided with a waistband part, and the back and both sides are formed by the first cloth part, The front part is formed by the second fabric part, so that only the circumference of the body including the lower abdomen and the back of the waist can be tightened, and the pelvis can be tilted forward. That is, during exercise, the muscles from the hips to the feet are kept in a relaxed state and can be moved freely.

The sports pants of the present invention are composed of at least a first fabric portion with strong fastening properties and a second fabric portion with weak fastening properties. The first cloth part covers the circumference of the body including the pelvis and lower abdomen, and the back is located higher than the front. A second fabric part with weak fastening is arranged on the lower part of the first fabric part. The upper end of the trousers is provided with a waistband portion, the back and both sides are formed by a first fabric portion, and the front portion is formed by a second fabric portion. In this way, tighten the circumference of the body including the lower abdomen and the back of the waist. Furthermore, the pelvis can be tilted forward, and the aforementioned pelvic forward tilt posture can be maintained. Moreover, by arranging the second fabric portion with weak tightness in the lower part of the first fabric portion, it is possible to prevent the gluteus maximus and the large movement of the lower abdomen including the crotch from being hindered.

A middle-fastening third fabric portion may be arranged between the first fabric portion and the second fabric portion and at a position that is continuous from both side surfaces to the back and covers a part of the gluteus medius. In this way, the larger movements of the gluteus medius are not hindered. This embodiment is suitable for women, and if it is for men, this part can also be used as the first cloth part with strong fastening.

Preferably, the first fabric portion is an elastic fabric containing elastic yarns, and the second fabric portion is an elastic knitted fabric including elastic yarns. The fabric is thinner, lighter in mass (mass per unit area), and higher in stretch (tightness), making it suitable for maintaining an anterior pelvic tilt. Knitted fabrics are suitable for keeping the muscles from the hips to the feet in a relaxed state, while maintaining free movement.

The first fabric portion is preferably a fabric portion formed by laminating two layers of elastic fabrics containing elastic yarns. If two layers of stretch fabric are laminated, it can show strong fastening. By containing elastic yarn, it is easy to stretch, and it is easy to follow the movement of muscles caused by exercise.

The second fabric portion is preferably a layer of elastic knitted fabric containing elastic yarn. If it is a single-layer knitted fabric, weak fastening is likely to occur, and the large movements of the gluteus maximus and the lower abdomen including the crotch will not be hindered.

The third fabric part is preferably a layer of elastic fabric containing elastic yarn. The third fabric portion is arranged at a position covering a part of the gluteus medius, so as not to hinder the large movement of the gluteus medius.

The elongation rate of each cloth part under the load of 17.6 N is preferably: the elongation rate of the first cloth part (S1) is 20-30% in the longitudinal direction and 10-20% in the transverse direction, and the elongation rate (S2) of the second cloth part is in the longitudinal direction. 160 to 190%, 70 to 100% in transverse direction, and the elongation of the third fabric part (S3) is 30 to 60% in longitudinal direction and 20 to 50% in transverse direction. Among them, there is a relationship of S1≦S3<S2. Moreover, the elongation rate can also be changed in the area|region of a 1st cloth part. For example, for the purpose of maintaining an anterior pelvic tilt posture and improving the wearing feeling, the elongation rate of 2b and 2d may be smaller than that of 2a and 2c. However, in this case, the relationship of S1≦S3<S2 is also satisfied.

The initial longitudinal elastic modulus (slope of stress at 5% elongation) of the first fabric portion is preferably three times or more that of the second fabric portion. Thereby, the 1st fabric part can tighten the circumference|surroundings of the body including the lower abdomen and the back of the waist, and can make the pelvis tilt forward and keep the pelvic forward tilt posture. In addition, the second fabric portion does not interfere with the large movements of the gluteus maximus and the lower abdomen including the crotch.

The upper end of the back of the first cloth part preferably exceeds the upper end of the pelvis, the front is located between the anterior superior spine of the ilium and the crotch, and the width of the first cloth part in the body length direction is wider than the front. Thereby, the pelvic forward tilt posture can be maintained more strongly. In addition, since the upper end of the back of the first fabric portion is positioned beyond the upper end of the pelvis, there is no situation in which the pants slide down due to the movement during exercise.

It is preferable that the 1st cloth part is a position higher than the center upper end part of the front surface by more than 60 mm at the center upper end part of the back surface. More preferably, it is 80 mm or more. The upper limit is preferably 120 mm or less. Thereby, the pelvic forward tilt posture can be maintained more strongly. Therefore, if the back and both sides of the waistband at the upper end of the pants are formed by the first cloth part and the front is formed by the second cloth part, the central upper end of the back can be placed higher than the central upper end of the front.

The mass per unit area (mass per unit area) of the first fabric portion 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 fabric 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 fabric portion is preferably 100 to 220 g/m ² , more preferably 120 to 200 g/m ² . The first cloth part may be used by laminating two layers of the third cloth part. If the mass per unit area is in the above-mentioned range, it is light and suitable for sports pants.

The waistband at the upper end of the trousers can be equipped with waist elastics in the front, but not in the sides and the back. In this way, the elasticity of the front waist elastic band can be used to put on and take off the pants, and there is no slippage caused by the movement during exercise. In addition, a cord may be attached to the waistband.

The length of the hem of the trousers only needs to be below the lower part of the crotch, and it can be a length of 2 to 100 cm from the lower part of the crotch.

In the present invention, the first and third fabrics are preferably woven fabrics, such as plain weave, twill weave, satin weave and the like. The second fabric is preferably a knitted fabric, for example, including circular knitted fabrics, horizontal knitted fabrics, longitudinal knitted fabrics (including Tricot knitted fabrics, Raschel knitted fabrics), terry knitted fabrics, and the like. Knitted fabrics, rib knitted fabrics, double knitted fabrics (double knitted fabrics), rib knitted fabrics, double reversed knitted fabrics, warp plain weave, warp pile weave, warp satin weave, chain weave, interlining weave, etc. The fibers used in the first to third fabrics are preferably polyethylene terephthalate (polyester) fiber yarn, polyethylene terephthalate (polyester) spun yarn, nylon fiber yarn, nylon spun yarn, Polyurethane yarn (elastic yarn) or a combination of these. It can also be made into a covered yarn formed by wrapping inelastic yarn around elastic yarn. The first to third fabrics are made into pants by sewing.

The effect of pelvic support is that if the pelvis is tilted forward, the center of gravity is forward, and the center of foot pressure becomes the direction of the toes. Also, the position of the center of gravity changes when the pelvis is tilted backward, in the neutral position, or tilted forward in the static posture, but the upper body can be tilted forward without bending the back bone. With the pelvis tilted forward, the legs are not easy to lift forward and upward, and the kicks of the feet to the oblique rear are enhanced. As a result, the forward tilt of the pelvis makes it difficult for the leg to lift forward and upward, the kicking of the foot obliquely rearward is enhanced, and the maximum extension movable area for swinging the foot backward is increased. In addition, the reaction of the oblique downward kick causes the maximum extension of the hip joint, and its influence causes the muscles such as the psoas major to contract rapidly. The psoas major is a muscle that is good at stretching and exerting force (eccentric contraction) at the same time, and exerts its maximum performance (force) at that moment. As described above, the pants of the present invention can tilt the pelvis forward, thereby promoting various movements such as translation, rotation, and lateral movement of the muscles.
