Description

Sports wear

The present invention relates to sports wear that can be worn on the upper body during running.

Conventionally, in order to correct the posture at the time of sports and assist the motor function, sports wear with a partial tension difference on the fabric has been proposed. For example, Patent Document 1 describes an undershirt that can correct the posture by forming a tightening portion by lining a bonded fabric around the armholes and the upper part of the back body. Further, in Patent Document 2, the first hardly stretchable member provided along the shoulder line and the first hardly stretchable member are provided continuously, with respect to the center line in the width direction in the vicinity of the neck portion. Throwing motion assisting wear having a second hardly stretchable member extending in an oblique direction is described. Patent Document 3 has a front tension area formed in a part of the front body and a back tension area formed in a part of the back body. The terrestrial sprint running wear that is larger than the tension of the part is described.

However, the undershirt described in Patent Document 1 corrects so that the back muscles are stretched out from the posture of the dorsum stooping around the back, and correction of movement during running has not been studied. Patent Document 2 discusses correcting the pitching form so that the position of the elbow does not fall, but does not discuss correcting the motion during running. Patent Document 3 discusses how to correct the trunk posture and make the pelvis upright to maximize the repulsive force from the ground at the landing point of the foot and convert the running power into running force without waste. However, it has not been studied to correct the movement of the upper limbs during running.

In order to solve the above-mentioned conventional problems, the present invention provides sports wear that can bring the movement of the upper limbs during running closer to the correct running form.

The present invention is a sports apparel made of stretchable fabric and worn on the upper body, including a front body, a back body and a sleeve, wherein the sleeve is the first of the upper trapezius muscle fibers. The present invention relates to a sportswear comprising a first tightening portion arranged so as to extend from the 7 cervical vertebra to the upper trapezius muscle fiber and the triceps surae and to the upper elbow.

The sleeve further passes from the seventh cervical vertebra at the origin of the upper trapezius muscle fiber to the upper trapezius muscle fiber, the biceps brachii, the medial or lateral elbow and the back of the forearm, and the central forearm or the far forearm. It is preferable to have the 2nd tightening part arrange | positioned so that it may reach a position part. The first tightening portion and the second tightening portion are preferably integrated in a region covering the trapezius muscle upper fibers.

It is preferable that the back body has a third tightening portion disposed in a region covering the inside of the scapula, the thoracic vertebra and the pelvis.

It is preferable that the front body has a fourth tightening portion disposed in a region covering a part of the iliac bone.

It is preferable that each of the first tightening portion, the second tightening portion, the third tightening portion, and the fourth tightening portion is made of a resin material disposed on the stretchable fabric.

In the sportswear worn on the upper body, the first tightening portion extends from the seventh cervical vertebra at the origin of the upper trapezius muscle fiber to the upper trapezius muscle fiber and the triceps and to the upper elbow. By providing the sportswear, sportswear that can bring the movement of the upper limb during running closer to the correct running form is provided.

FIG. 1A is a front view of sports wear according to an embodiment of the present invention, and FIG. 1B is a rear view thereof. FIG. 2A is a front view of sports wear according to another embodiment of the present invention, and FIG. 2B is a rear view thereof. FIG. 3A is a front view of sports wear according to another embodiment of the present invention, and FIG. 3B is a rear view thereof. FIG. 4 is a cutting pattern diagram of the sportswear of the first embodiment. FIG. 5 is a cutting pattern diagram of the sports wear of the second embodiment.

During running, upper limb movements such as swinging the arm affect the stability of the upper body. Conventional sports wear such as compression tops for running has some that tighten the trunk as described in Patent Document 3, but it has been studied to correct the movement of the upper limb during running. There was nothing. The inventors of the present invention diligently studied to maintain the stability of arm swinging in the upper limb running motion. As a result, the upper limb during running is provided by providing a vertically long first tightening portion in a region extending from the seventh cervical vertebra at the origin of the upper trapezius muscle fiber to the upper trapezius muscle fiber and the triceps, to the upper elbow. The present invention has been found to bring the movement of the movement closer to the correct running form.

The sportswear of the present invention is made of stretchable fabric (hereinafter also referred to as main fabric). In the present invention, “having stretchability” means the stretch rate in the circumferential direction of the body of the fabric forming the sportswear (hereinafter, also simply referred to as the short-axis stretch rate) and / or the stretch in the body length direction. It means that the ratio (hereinafter, simply referred to as “long-axis elongation ratio”) exceeds 0%. In the present invention, the elongation rate means a value measured according to JIS L 1096. Specifically, the length of the fabric piece in a state where no load is applied is A, and a state where a load of 15 N is applied. When the length of the dough piece is B, the elongation rate is calculated by (B−A) / A × 100. In the present invention, although not particularly limited, the major axis elongation of the main body fabric is preferably 80 to 120%, more preferably 90 to 110%. In the present invention, although not particularly limited, the short axis elongation of the dough is preferably 160 to 200%, more preferably 170 to 190%.

In the present invention, the “tightening portion” refers to a portion having a stronger tightening force than the main body fabric. Usually, the lower the stretch rate of the fabric, the stronger the tightening force. In the present invention, the strong tightening force means that the stretch rate is low and the stretch rate in the body length direction is low. The tightening portion may be formed by double-striking another fabric on the main body fabric. However, from the viewpoint of easily adjusting the tightening force, the tightening portion is preferably formed by arranging a resin material on the main body fabric. By arranging the resin material on the main body fabric to form the tightening portion such as the first tightening portion, the stretchability of the tightening portion can be controlled by the shape of the resin material. Although not particularly limited, the long-axis elongation rate of the tightening portion is preferably 30 to 70%, more preferably 40 to 60%. In the present invention, although not particularly limited, the short axis elongation of the dough is preferably 55 to 95%, more preferably 65 to 85%.

In the present invention, the fabric is not particularly limited as long as it has elasticity. For example, a woven fabric or a knitted fabric can be used. As the woven fabric, for example, plain weave, oblique weave, satin weave, altered plain weave, altered satin weave, altered satin weave, alter weave, crest weave, one-ply weave, double structure, multiple structure, warp pile weave, weft pile weave, Examples include tangle weaving. Examples of knitted fabrics include round knitting, weft knitting, warp knitting (including tricot knitting and raschel knitting), pile knitting, flat knitting, tengu knitting, rib knitting, smooth knitting (double-sided knitting), rubber knitting, pearl knitting, Denby organization , Cord tissue, atlas tissue, chain tissue, insertion tissue and the like. The dough is not particularly limited. For example, the fabric weight is preferably in the range of 160 to 340 g / m ² , more preferably in the range of 180 to 280 g / m ² . If it is said range, there exists an advantage which does not impair a motor function, is durable, is light and is easy to move.

The fiber constituting the fabric is not particularly limited. For example, polyester fiber such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyurethane fiber, polyamide fiber, acetate fiber, cotton fiber, rayon fiber, ethylene vinyl alcohol fiber. Nylon fiber or the like can be used.

The sports wear is worn on the upper body and includes a front body, a back body, and a sleeve. The sleeve is connected to the front body and the back body at the shoulder. The sleeve may have a seven-part sleeve shape that extends to the vicinity of the center of the wearer's forearm, and may have an eight-part or nine-part sleeve shape that reaches the distal part of the wearer's forearm. You may have and it may have a long sleeve type | mold shape which reaches to a wearer's wrist vicinity.

The sleeve portion has a first tightening portion, and the first tightening portion extends from the seventh cervical vertebra of the upper trapezius muscle fiber to the upper elbow through the upper trapezius muscle fiber and the triceps. Are arranged as follows. The first tightening portion is formed by a vertically long curved line on the rear surface of the upper arm portion. By the first tightening portion, it is possible to give a tension for pulling the upper arm backward. Thereby, an arm does not go too much forward at the time of running, but an arm can be shaken back firmly, and the movement of the upper limb at the time of running can be brought close to a correct running form.

The sleeve further passes from the seventh cervical vertebra at the origin of the upper trapezius muscle fiber to the upper trapezius muscle fiber, the biceps brachii, the medial part of the elbow or the outer side of the knee and the rear surface of the forearm, and the middle part of the forearm or the forearm It is preferable to have the 2nd tightening part arrange | positioned so that it may reach a position part. The second tightening portion is formed by a vertically long curved line extending from the front surface of the upper arm through the inner side of the elbow or the outer side of the elbow to the rear surface of the forearm to reach the center of the forearm or the distal portion of the forearm. By the second tightening portion, it is possible to promote the bending of the elbow and support the holding of the bending posture of the elbow. Thereby, there is little bending and stretching of the elbow, the arm can be shaken stably, and the movement of the upper limb during running can be brought closer to the correct running form. The second tightening portion is preferably connected (integrated) with the first tightening portion and a region covering the trapezius muscle upper fiber. As a result, the end of the neck becomes an anchor, and the effect of bringing the movement of the upper limb during running by the first tightening portion and the second tightening portion closer to the correct running form is easily exhibited.

It is preferable that the back body has a third tightening portion disposed in a region covering the inside of the scapula, the thoracic vertebra and the pelvis. The third tightening portion can pull the scapula, support the spine, and tighten the trunk. Therefore, the spine stands during running, pulls the scapula and keeps the chest stretched, and the effect of bringing the movement of the upper limb during running by the first tightening portion and the second tightening portion closer to the correct running form is obtained. It becomes easy.

It is preferable that the front body has a fourth tightening portion disposed in a region covering a part of the iliac bone. The fourth tightening portion has an effect of suppressing the trunk swing in cooperation with the third tightening portion disposed in the region covering the pelvis.

The first tightening portion, the second tightening portion, the third tightening portion, and the fourth tightening portion are made of a resin material disposed on the main body fabric from the viewpoint of easily adjusting stretchability, that is, tightening force. It is preferable to apply and configure. As the resin material, an elastic material can be used. For example, polyurethane, silicone resin, polyvinyl chloride, polyamide elastomer, polyester elastomer, rubber elastomer, olefin elastomer, polyethylene, polypropylene, nylon, EVA (ethylene / vinyl acetate copolymer), ABS (acrylonitrile-butadiene-styrene copolymer) Polymer) and the like.

The shape of the resin material in the tightening portion is not particularly limited. The resin material may be any shape such as, for example, a linear shape, a honeycomb shape, a todd shape, a columnar shape, a semispherical shape, a quadrangular prism shape, a triangular prism shape, a conical shape, a quadrangular pyramid shape, a triangular pyramid shape, and combinations thereof. Also good. Although not particularly limited, for example, the tightening portion is formed by applying these resin materials in a flowable state (for example, liquid) to the main body fabric by printing, heating, and curing. The tightening force of the tightening portion can be adjusted by adjusting the shape, thickness, density, and the like of the resin material.

The sportswear of Examples 1 and 2 and Comparative Example 1 was worn by 7 subjects (male), and the influence on running form during running was confirmed as follows.

(Arm swing and elbow angle maintenance)
The arm swing and elbow angle maintenance were evaluated by measuring the upper arm angle Max and the forearm angle MaxMin with the Mizuno running form diagnostic system “FORM”. The results are shown in Table 1 below. The data in Table 1 is an average value of 7 subjects. The upper arm angle Max is “−”, and the higher the absolute value, the more firmly the arm swings backward. Further, the lower the value of the forearm angle MaxMin, the more the angle of the elbow is maintained, the less the elbow is bent and stretched, and the arm is stably shaken. Here, the upper arm angle Max is the maximum angle of a perpendicular line passing through the acromus projected onto the sagittal plane and a line connecting the acromion and the outer elbow, and the back side is negative. The forearm angle MaxMin is a difference between the maximum value and the minimum value of an angle formed by a line connecting the acromus projected to the sagittal plane and the outer elbow and a straight line connecting the outer elbow and the ulnar styloid process.

(Posture correction)
For posture correction, subjects with markers on the outer heel and shoulder caps wear the sports wear of the example and the comparative example, take a digital photograph from the side, and display the outer heel marker when projected on the sagittal plane The distance between the perpendicular line (posture axis) and the acromial marker was measured and evaluated. The results are shown in Table 1 below. The data in Table 1 is an average value of 7 subjects. The smaller the distance between the posture axis and the shoulder peak, the more the trunk is tightened and the chest is stretched.

From the results of Table 1, when wearing the sportswear of Examples 1 and 2, compared to the case of wearing the sportswear of Comparative Example 1, the arm does not go too far forward during running, and the arm swings firmly behind I found out. Moreover, when the sportswear of Examples 1 and 2 was worn, compared with the case where the sportswear of the comparative example 1 was worn, it turned out that bending and stretching of an elbow are few. Moreover, when the sportswear of Examples 1 and 2 was worn, it was in a posture where the chest was stretched compared to the case where the sportswear of Comparative Example 1 was worn. When the sportswear of Example 2 was worn, as compared with the case of wearing the sportswear of Example 1, the trunk was tightened and the chest was more stretched.
