本発明は、水中姿勢を安定化させるとともに、ハムストリングスの動きをサポートする水着を提供することができる。 INDUSTRIAL APPLICABILITY The present invention can provide a swimsuit that stabilizes the underwater posture and supports the movement of the hamstrings.
本発明者らは、水着による水中姿勢の安定及びハムストリングスの動きをサポートする効果を両立させるため、鋭意検討した。まず、クロール、バタフライ、背泳ぎ及び平泳ぎ時の下半身の背部における皮膚の伸びを特許３８３１３４８号公報に記載の手法を用いて解析した。その結果を図９に示している。（ａ）はクロール、（ｂ）はバタフライ、（ｃ）は背泳ぎ、（ｄ）は平泳ぎの場合を示す。図９において、２００は皮膚の伸びの度合を示し、ＩからＩＩ方向へ行くほど、皮膚の伸びの程度が高いことを示す。図９から分かるように、各種水泳時に、臀部のトップからハムストリングスの近位１／３を覆う領域の皮膚伸びが大きかった。本発明の水着では、左右それぞれの臀部から大腿部に掛けて、体長方向（身長方向とも称される。）に沿って２本以上の帯状の緊締部が互いに交差するよう、かつ前記２本以上の帯状の緊締部の交点（以下において、単に「交点」とも記す。）が、図１０に示されているように、水泳時の皮膚延びが大きい臀部のトップからハムストリングスの近位１／３までの領域に位置するように配置することで、水中姿勢を安定化させるとともに、ハムストリングスの動きをサポートすることができる。例えば、水泳時の大臀筋、中臀筋、小殿筋及びハムストリングスを含む股関節伸筋群、並びに半腱様筋、半腱膜筋、中臀筋(外側)、小殿筋(外側)及び大腿筋膜張筋を含む股関節内旋筋群の筋負担が軽減される。ハムストリングスは、大腿後面（下肢後面）にある大腿二頭筋、半膜様筋、半腱様筋を合わせた呼び方である。本明細書において、「ハムストリングスの近位１/３」とは、ハムストリングスの近位端から遠位端までの身長方向の長さを１００％とした場合、近位端からの距離が１００％/３である部位をいう。また、「臀部のトップ」とは、大殿筋の上端から下端までの身長方向の長さを１００％とした場合、大殿筋の下端からの距離が１００％/２である部位をいう。 The inventors diligently studied in order to achieve both the stability of the underwater posture by the swimsuit and the effect of supporting the movement of the hamstrings. First, the skin elongation on the back of the lower half of the body during crawl, butterfly, backstroke and breaststroke was analyzed using the method described in Japanese Patent No. 3831348. The result is shown in FIG. (A) shows the case of crawling, (b) shows the case of butterfly, (c) shows the case of backstroke, and (d) shows the case of breaststroke. In FIG. 9, 200 indicates the degree of skin elongation, and the degree of skin elongation increases in the direction I to II. As can be seen from FIG. 9, during various types of swimming, the skin stretched from the top of the buttocks to the region covering the proximal 1/3 of the hamstrings was large. In the swimsuit of the present invention, the two or more strip-shaped tightening portions cross each other along the body length direction (also referred to as the body height direction) by hanging from the left and right buttocks to the thighs, and As shown in FIG. 10, the intersection of the above band-shaped tightening portions (hereinafter, also simply referred to as “intersection”) is 1/proximal to the hamstrings from the top of the buttocks where the skin stretches greatly during swimming. By arranging so as to be located in the region up to 3, it is possible to stabilize the underwater posture and support the movement of the hamstrings. For example, the hip extensor group including the gluteus maximus muscles, gluteus medius muscles, gluteus maximus muscles and hamstrings during swimming, as well as the semitendinosus, semitendinal muscles, gluteus medius muscle (outer side), gluteus maximus muscle (outer side). And the muscle load of the hip joint internal rotator muscle group including the fascia lata muscles is reduced. Hamstrings are the names that combine the biceps femoris, the semimembranosus, and the semitendinosus muscles on the posterior surface of the thigh (the posterior surface of the lower limb). In the present specification, “proximal ⅓ of hamstrings” means that the distance from the proximal end is 100 when the lengthwise direction length from the proximal end to the distal end of the hamstrings is 100%. The part that is %/3. In addition, the “top of the buttocks” refers to a region where the distance from the lower end of the gluteus maximus is 100%/2 when the length in the height direction from the upper end to the lower end of the gluteus maximus is 100%.
本発明において、「伸縮性生地」とは、生地の体長方向における伸長率が０％を超えることを意味する。本発明において、生地の伸長率は、ＪＩＳ Ｌ １０９６ ８．１４．１ Ａ法（荷重１７．６Ｎ、引張速度２００ｍｍ／ｍｉｎ）に基づいて測定するものである。 In the present invention, the “stretchable fabric” means that the elongation rate of the fabric in the body length direction exceeds 0%. In the present invention, the elongation rate of the cloth is measured based on the JIS L 1096 8.14.1 A method (load 17.6 N, pulling speed 200 mm/min).
前記緊締部は、他の部分より緊締力、すなわち、体長方向の引張弾性率が高い。本発明の水着において、緊締部の引張弾性率は水着の本体を構成する伸縮性生地の引張弾性率より高く、緊締部のうち、交点の引張弾性率が最も高い。本発明において、引張弾性率は、ＪＩＳ Ｌ １０９６ ８．１４．Ａ法に基づいて、具体的には、生地片が幅５ｃｍ、長さ１０ｃｍになるように引張試験機に固定し、５％伸長時の応力の傾きから引張弾性率（Ｎ／ｍｍ2）を求める。生地片の長さは、測定方向と一致する方向のサイズを意味する。例えば、体長方向の引張弾性率を測定する場合、生地片の長さは、生地片の体長方向のサイズを意味し、身幅方向の引張弾性率を測定する場合、生地片の長さは、生地片の身幅方向のサイズを意味する。The tightening portion has a higher tightening force, that is, a tensile elastic modulus in the body length direction, than the other portions. In the swimsuit of the present invention, the tensile elastic modulus of the tightening portion is higher than the tensile elastic modulus of the stretchable fabric forming the body of the swimwear, and the tensile elastic modulus at the intersection of the tightening portions is the highest. In the present invention, the tensile elastic modulus is JIS L 1096 8.14. Based on the method A, specifically, the dough piece was fixed to a tensile tester so that the width was 5 cm and the length was 10 cm, and the tensile elastic modulus (N/mm 2 ) was calculated from the slope of the stress at 5% elongation. Ask. The length of the dough piece means the size in the direction coinciding with the measuring direction. For example, when measuring the tensile elastic modulus in the body length direction, the length of the dough piece means the size in the body length direction of the dough piece, and when measuring the tensile elastic modulus in the width direction, the length of the dough piece is It means the size of the strip in the width direction.

（引張弾性率の測定）
ＪＩＳ Ｌ １０９６ ８．１４．Ａ法に基づいて、具体的には、生地片を幅５ｃｍ、長さ１０ｃｍになるように引張試験機に固定し、５％伸長時の応力の傾きから体長方向の引張弾性率（Ｎ／ｍｍ2）を求めた。(Measurement of tensile modulus)
JIS L 1096 8.14. Based on the A method, specifically, the dough piece was fixed to a tensile tester so that the width was 5 cm and the length was 10 cm, and the tensile elastic modulus (N/mm) in the body length direction was calculated from the inclination of the stress at 5% elongation. 2 ) asked.
表１のデータから分かるように、皮膚が伸びやすい領域に配置した２本の緊締部が交差している交点の体長方向の引張弾性率が、２本の交差していない緊締部を含む場合の体長方向の引張弾性率より高く、水中姿勢を安定化させるとともに、ハムストリングスの動きを効果的にサポートすることができる。 As can be seen from the data in Table 1, when the elastic modulus in the body length direction at the intersection point where two tightening portions arranged in an area where the skin is easily stretched intersects, when two tightening portions that do not intersect are included. It is higher than the tensile elastic modulus in the body length direction, stabilizes the underwater posture, and can effectively support the movement of the hamstrings.
実施例１の水着及び比較例１の水着を全国大会上位レベル男子大学生８名に着用させ、１２．５ｍＳＬＤにおけるタイムを測定した。また、実施例２及び比較例２の水着全国大会上位レベル女子大学生６名に着用させ、１５ｍＳＬＤにおけるタイムを測定した。その結果を下記表２及び表３に示した。 The swimsuit of Example 1 and the swimsuit of Comparative Example 1 were put on by eight national university top-level male college students, and the time at 12.5 mSLD was measured. In addition, 6 swimwear national competition upper level female college students of Example 2 and Comparative Example 2 were worn and the time at 15 mSLD was measured.

Was able to effectively support the posture retention of
実施例１と比較例１の水着を着用して水泳する際（クロール時）の関節伸筋群及び股関節内旋筋群の筋張力を、特許５９２０７２４特許３８３１３４８号公報に記載の手法を用いて評価し、その結果を下記表４に示した。股関節伸筋群は、大臀筋、中臀筋、小殿筋及びハムストリングスを含み、股関節内旋筋群は、半腱様筋、半腱膜筋、中臀筋(外側)、小殿筋(外側)及び大腿筋膜張筋を含む。 Evaluation of the muscle tensions of the joint extensor muscle group and the hip joint internal rotator muscle group during swimming (when crawling) while wearing the swimwear of Example 1 and Comparative Example 1 using the method described in Japanese Patent No. 5920724, Japanese Patent No. 3831348. The results are shown in Table 4 below. The hip extensor group includes the gluteus maximus, gluteus medius, gluteus maximus and hamstrings, and the hip internal rotator group includes the semitendinosus, semitendinal muscle, gluteus medius (outer side) and gluteus maximus.

表４のデータから、実施例の水着を着用した場合、比較例の水着を着用した場合に比べて、クロール動作時の股関節伸筋群及び股関節内旋筋群の筋張力が小さく、左右それぞれの臀部から大腿部に掛けて、体長方向に沿って２本の帯状の緊締部を互いに交差するように、かつ、２本以上の帯状の緊締部の交点が臀部のトップからハムストリングスの近位１／３の間に位置するように配置することで、ハムストリングスがサポートされ、ひいては股関節伸筋群及び股関節内旋筋群がサポートされていることが分かった。 From the data in Table 4, when the swimwear of the example was worn, the muscle tension of the hip extensor group and the hip joint internal musculature group during crawl action was small compared to the case of wearing the swimwear of the comparative example. From the buttocks to the thighs, cross the two band-shaped tightening parts along the lengthwise direction, and the intersection of the two or more band-shaped tightening parts should be close to the hamstrings from the top of the buttocks. By arranging the hamstrings so as to be positioned between 1/3, it was found that the hamstrings were supported, and by extension, the hip extensor group and the hip internal rotator group were supported.
