以下、第1の本発明の実施形態について詳細に説明する。
第1の本発明のボトム衣料は、弾性糸を含み、身生地と内生地から構成され、身生地の内側に内生地が重なっており、内生地の少なくとも一部は身生地と接着されていない2重構造が存在するボトム衣料であって、内生地の製品におけるタテ方向の80%伸長時の応力をAとし、内生地の製品におけるヨコ方向の80%伸長時の応力をBとした場合、0.1≦A/B<1.0であることを特徴とする。
また、非弾性糸は、フィラメント糸又は紡績糸のいずれであってもよい。
フィラメント糸の形態は、原糸(未加工糸)、仮撚加工糸、先染糸などのいずれであってもよく、また、これらの複合糸であってもよい。複合糸は、エア混繊、合撚、カバリング、仮撚混繊等、特に限定されない。フィラメント糸の断面形状は〇、△、十字、W型、M型、C型、I型、ドッグボーン型、中空糸など特に制限はない。
紡績糸の形態は、単独又は混紡されたもの等、いずれであってもよい。混紡方法においても特に限定されないが、ピリングの発生がしにくいMVS方式で得られる紡績糸が好ましい。
非弾性糸にはブライト糸、セミダル糸、フルダル糸等任意に選択できる。
セルロース繊維は、フィラメント糸の形態では、原糸(未加工糸)、仮撚加工糸、先染糸などのいずれであってもよく、上述の複合糸でもよい。また、セルロース繊維が紡績糸の形態では、単独又は混紡されたもの等、いずれであってもよい。
本実施形態のボトム衣料の身生地に一部配される弾性糸は、破断伸度100%以上の繊維を指す。弾性糸のポリマーや紡糸方法は特に限定されず、ポリウレタン弾性糸(スパンデックス又はスパンデックス繊維ともいう。)、ポリエーテル・エステル弾性糸、ポリアミド弾性糸、ポリオレフィン弾性糸が挙げられ、例えば、ポリウレタン弾性糸では、乾式紡糸又は溶融紡糸したものが使用できる。また、これらの弾性糸に非弾性糸を被覆し、カバリング状態としたものでもよい。更に天然ゴム、合成ゴム、半合成ゴムからなる糸状である、いわゆるゴム糸などを使用することもできるが、伸縮性に優れ、一般的に広く利用されているポリウレタン弾性糸が好適である。その中でも、ポリウレタンポリマーを構成するジオール成分が側鎖を有することが好ましく、該側鎖がメチル基であることがより好ましく、同一の炭素上にメチル基を2つ有することが更に好ましい。
弾性糸は、染色加工時のプレセット工程における通常の処理温度である180℃近辺で伸縮性を損なわないことが好ましい。また、特殊ポリマーや粉体が添加された、高セット性、消臭性、抗菌性、吸湿性、吸水性等の機能性を有する弾性糸も使用可能である。弾性糸の繊度については、10dtex~700dtex(デシテックス、以下同じ記号を使用する)程度の繊維の使用が可能であり、弾性糸でルーピングを行なう場合は、12dtex~250dtex程度の弾性糸の使用が好ましく、ラッシェル編機を使用して弾性糸の挿入編成を行なう場合は、70dtex~700dtexの弾性糸の使用が好ましい。
経編の場合は、ラッシェル編機又はトリコット編機により、弾性糸が挿入又はルーピングされている組織が好適に用いられる。ラッシェルの組織では6コースサテン、4コースサテン、6コースチュール、トリコネットなど太いスパンデックス繊維を挿入した組織が好適に用いられ、スパンデックスを2本挿入し、タテヨコに伸びを持つ組織が着用感の点から特に好ましい。トリコットではハーフトリコット、二目編み、アトラス組織などが、伸縮性が良いため好ましい。
丸編の場合は、弾性糸がルーピングされているものが好ましい。
身生地としては、弾性繊維を織り込んだ織物も好適に用いられる。
身生地の目付としては、50~400g/m2である生地が好適に用いられる。
また、身生地のタテ方向の50%伸長時の応力は0.3N~4Nが好ましい。タテ方向の50%伸長時の応力が4N以下であれば、座る、しゃがむなどの動作時の動作追随性が高まる。他方、0.3N以上では、着用感を高め、動作時等の体の振動を抑制しやすくなる。尚、本明細書において、「ヨコ方向」とは、ボトム製品における周囲方向(着用時の人体周囲方向)を指し、「タテ方向」とは、ボトム製品における上下方向(着用時の人体身長方向)を指す。
内生地としては、織物又は編物が用いられ、製品により適宜選択されるが、伸縮性の観点からは編物が好ましい。経編の場合は、ラッシェル編機又はトリコット編機により、弾性糸が挿入又はルーピングされている組織が好適に用いられる。ラッシェルの組織では、6コースサテン、4コースサテン、6コースチュール、トリコネットなど、太いスパンデックス繊維を挿入した組織が好適に用いられ、スパンデックスを2本挿入し、タテヨコに伸びを持つ組織が、着用感の点から特に好ましい。ジャカードラッシェルにて、内生地のパネル内で生地の伸張応力に差があってもよい。トリコットの組織では、ハーフトリコット、二目編み、アトラス組織などが、伸縮性が良いため好ましい。丸編の場合は、弾性糸がルーピングされているものが好ましい。織物としては、弾性繊維を織り込んだ織物が好適に用いられる。内生地の目付としては、50~400g/m2である生地が好適に用いられる。
このため、O脚やX脚への矯正効果が望め、本発明のボトム衣料を着用することで歩行補助効果に優れる。
ただし、内生地のヨコ方向の伸長時の応力が大きすぎると、着用時の締め付けが強くなり、快適性が低下してしまう。
図1においては、腰部から臀部下部を覆うように内生地が配置されている。本生地の配置においては、着用時に内生地の腰部から臀部における伸び量が、臀部下部に対応する部位の生地の伸び量より大きくなることから、内生地が臀部下部方向へ引っ張られることにより、太もも部を外側に引っ張る力(外旋力)が発生することにより、脚を外旋させる効果が得られる。
図2においては、太もも付け根部もしくは鼠径部から臀部上部もしくは臀溝~太腿上部において内生地が配置されている。本生地の配置においては、着用時に背面部に対応する内生地の伸び量より前面部に対応する内生地の伸び量が大きくなることから、内生地が前面側に引っ張られることにより、太もも部を内側に引っ張る力(内旋力)が発生することにより、脚を内旋させる効果が得られる。
また、内旋力を発生させるためには、平置き時のボトム衣料前面において、前記内生地の脇端部の接着部の70%以上が、股部より5cm上の点を通る水平線よりも下部に接着していることが好ましい。図2に示すように、内生地の両端の太実線で示した部分が脇端部の接着部であり、この太実線の70%が前記股部の5cm上の点を通る水平線よりも株に位置していると、内旋力が発生しやすい。
内生地の端部が股部上方5cmの領域より上部にある場合は、前面における内生地の伸張は、背面に比べて小さくなり、下部にある場合は、前面における内生地の伸張は、背面に比べて大きくなることから、それぞれ、着用時に外旋力と内旋力が発生することとなる。
高齢者向けボトム衣料は、やや弱めの着圧で履き易さを高めることが好ましく、臀部の着圧は5hPa~15hPaが好ましい。臀部の着圧が前記範囲にあることで、履き易さも向上する。
内生地は、ハーフパンツやコンプレッションウエアの脚の部分にも重ねることができ、太ももの揺れ、脹脛の揺れを抑えることができる。
以下、第2の本発明を実施するための実施の形態について詳細に説明する。
第2の本発明のボトム衣料は、弾性糸を含む身生地と内生地から構成され、身生地の内側に該内生地が重なっており、該内生地の少なくとも一部は該身生地と接着されていない2重構造が存在するボトム衣料であって、内生地のタテ方向中央線が、ボトム衣料の脇部において、大転子相当部よりもタテ方向下側に位置することを特徴とする。
また、非弾性糸は、フィラメント糸又は紡績糸のいずれであってもよい。
フィラメント糸の形態は、原糸(未加工糸)、仮撚加工糸、先染糸などのいずれであってもよく、また、これらの複合糸であってもよい。複合糸は、エア混繊、合撚、カバリング、仮撚混繊等、特に限定されない。フィラメント糸の断面形状は〇、△、十字、W型、M型、C型、I型、ドッグボーン型、中空糸など特に制限はない。
紡績糸の形態は、単独又は混紡されたもの等、いずれであってもよい。混紡方法においても特に限定されないが、ピリングの発生がしにくいMVS方式で得られる紡績糸が好ましい。
非弾性糸にはブライト糸、セミダル糸、フルダル糸等任意に選択できる。
セルロース繊維は、フィラメント糸の形態では、原糸(未加工糸)、仮撚加工糸、先染糸などのいずれであってもよく、上述の複合糸でもよい。また、セルロース繊維が紡績糸の形態では、単独又は混紡されたもの等、いずれであってもよい。
本実施形態のボトム衣料の身生地に一部配される弾性糸は、破断伸度100%以上の繊維を指す。弾性糸のポリマーや紡糸方法は特に限定されず、ポリウレタン弾性糸(スパンデックス又はスパンデックス繊維ともいう。)、ポリエーテル・エステル弾性糸、ポリアミド弾性糸、ポリオレフィン弾性糸が挙げられ、例えば、ポリウレタン弾性糸では、乾式紡糸又は溶融紡糸したものが使用できる。また、これらの弾性糸に非弾性糸を被覆し、カバリング状態としたものでもよい。更に天然ゴム、合成ゴム、半合成ゴムからなる糸状である、いわゆるゴム糸などを使用することもできるが、伸縮性に優れ、一般的に広く利用されているポリウレタン弾性糸が好適である。その中でも、ポリウレタンポリマーを構成するジオール成分が側鎖を有することが好ましく、該側鎖がメチル基であることがより好ましく、同一の炭素上にメチル基を2つ有することが更に好ましい。
弾性糸は、染色加工時のプレセット工程における通常の処理温度である180℃近辺で伸縮性を損なわないことが好ましい。また、特殊ポリマーや粉体が添加された、高セット性、消臭性、抗菌性、吸湿性、吸水性等の機能性を有する弾性糸も使用可能である。弾性糸の繊度については、10dtex~700dtex(デシテックス、以下同じ記号を使用する)程度の繊維の使用が可能であり、弾性糸でルーピングを行なう場合は、12dtex~250dtex程度の弾性糸の使用が好ましく、ラッシェル編機を使用して弾性糸の挿入編成を行なう場合は、70dtex~700dtexの弾性糸の使用が好ましい。
経編の場合は、ラッシェル編機又はトリコット編機により、弾性糸が挿入又はルーピングされている組織が好適に用いられる。ラッシェルの組織では6コースサテン、4コースサテン、6コースチュール、トリコネットなど太いスパンデックス繊維を挿入した組織が好適に用いられ、スパンデックスを2本挿入し、タテヨコに伸びを持つ組織が着用感の点から特に好ましい。トリコットではハーフトリコット、二目編み、アトラス組織などが、伸縮性が良いため好ましい。
丸編の場合は、弾性糸がルーピングされているものが好ましい。
身生地としては、弾性繊維を織り込んだ織物も好適に用いられ、特に経糸、緯糸のどちらにも弾性繊維を織り込んだ織物が好ましい。
また、身生地のタテ方向の50%伸長時の応力は0.3N~4Nが好ましい。タテ方向の50%伸長時の応力が4N以下であれば、座る、しゃがむなどの動作時の動作追随性が高まる。他方、0.3N以上では、補整効果が高まる。尚、本明細書において、「ヨコ方向」とは、ボトム製品における周囲方向(着用時の人体周囲方向)を指し、「タテ方向」とは、ボトム製品における上下方向(着用時の人体身長方向)を指す。
内生地としては、織物又は編物が用いられ、製品により適宜選択されるが、伸縮性の観点からは編物が好ましい。経編の場合は、ラッシェル編機又はトリコット編機により、弾性糸が挿入又はルーピングされている組織が好適に用いられる。ラッシェルの組織では、6コースサテン、4コースサテン、6コースチュール、トリコネットなど、太いスパンデックス繊維を挿入した組織が好適に用いられ、スパンデックスを2本挿入し、タテヨコに伸びを持つ組織が、着用感の点から特に好ましい。ジャカードラッシェルにて、内生地のパネル内で生地の伸張応力に差があってもよい。トリコットの組織では、ハーフトリコット、二目編み、アトラス組織などが、伸縮性が良いため好ましい。丸編の場合は、弾性糸がルーピングされているものが好ましい。内生地としては、弾性繊維を織り込んだ織物も好適に用いられ、特に経糸、緯糸のどちらにも弾性繊維を織り込んだ織物が好ましい。
タテ方向中央線とは、内生地のタテ方向における中心部を結ぶ線であり、図中、細点線で示している。
着用者の大転子の下側にタテ方向中央線が位置するように内生地を配することで、大腿骨において大転子により近い位置に緊締力をかけることができ、脇方向(外側)から内側に向う力、あるいは、内側から脇方向に向う力により効率的に大腿骨を旋回させることができる。これにより、O脚やX脚への矯正効果が望め、さらに下肢が適正に旋回することで、骨盤の位置を正しい位置に収めることができる。
脇部において、大転子相当部よりもタテ方向下側に上端部が位置するように内生地を配することで、大転子に緊締力をかけずに矯正効果を得ることができ、動作時に動きを阻害しにくく、動きやすいボトムとなる。
大腿骨において大転子により近い部位で緊締力をかけることにより、効率的に矯正効果を得ることができる。
図3~6においては、腰部もしくは鼠径部から臀部下部もしくは太もも部を覆うように内生地が配置されている。本生地の配置においては、着用時に内生地が腰部もしくは鼠径部から臀部下部もしくは太もも部方向へ引っ張られることにより、太もも部を外側に引っ張る力(外旋力)が発生することにより、足を外旋させる効果が得られる。
内生地の配置が図3のとき、A>B>Cであり、大転子との内生地上端部との距離が近いとき、効果的に外旋力が発生する。
内生地の配置が図4のとき、A=B>Cであり、図3よりも低い外旋力が発生する。
内生地の配置が図5のとき、A>B>Cであるが、図3よりも内生地の傾きが小さく、図3よりも低い外旋力が発生する。
内生地の配置が図6のとき、A>B>Cであるが、内生地上端部もしくは内生地のタテ方向中央線が大転子相当部よりも上方向に来るため、図3よりも動きにくさを感じる。内生地上端部が大転子相当部よりも上方向のときは、図3よりも低い外旋力が発生し、内生地上端部および内生地のタテ方向中央線が大転子相当部よりも上方向に来る場合は外旋力が発生しにくい。
内生地の配置が図7のとき、B>AかつB>Cであり、大転子との内生地上端部との距離が近いとき、効果的に内旋力が発生する。
内生地の配置が図8のとき、A=B=Cであり、図7よりも低い内旋力が発生する。
内生地の配置が図9のとき、B<AかつB<Cであり、図8よりも低い内旋力が発生する。
内生地の配置が図10のとき、B>AかつB>Cであるが、図7よりも前面部の内生地の傾きが小さく、図7よりも低い内旋力が発生する。
内生地の配置が図11のとき、B>AかつB>Cであるが、図7よりも背面部の内生地の傾きが小さく、図7よりも低い内旋力が発生する。
内生地の端部のうち、20%~70%は接着されないことが好ましく、接着されない部位は内生地の下端部であることが好ましい。更に、内生地の下端部全長に対する、該内生地の身生地と接着していない端部の割合が20%~100%であると、前部側から臀部側にかけて、内生地の伸張バランスに変化が生じやすく、太もも部を外側又は内側に引き寄せる力が強くなるため、好ましい。尚、接着される部分と接着されない部分は連続していても不連続でもよい。
内生地は、脇部から太もも部側への傾きが大きくなるよう配置することで、足を回旋させる効果が得られる。
内生地の端部が股部上方5cmの領域より上部にある場合は、前面における内生地の伸張は、背面に比べて小さくなることから、着用時に外旋力が発生することとなる。
前面上部~脇部~背面と内生地がらせん状に存在することで、着用時に太もも部を外側に引っ張り外旋力を効果的に発生させることができる。
本生地の配置においては、着用時に内生地の臀部下部に対応する部位の生地の伸び量が、腰部から臀部における伸び量より大きくなることから、内生地が臀部下部方向へ引っ張られることにより、太もも部を外側に引っ張る力(外旋力)が発生することにより、足を外旋させる効果が得られる。
内生地の端部が股部上方5cmの領域より下部にある場合は、前面における内生地の伸張は、背面に比べて大きくなることから、着用時に内旋力が発生することとなる。
前面~脇部の内生地配置がB>AであることでBがより大転子に近い位置となり、着用時に太もも部を内側に引き寄せて内旋力を効果的に発生させることができる。また、背面ではB>Cとすることで動作時に動きを阻害せず、動きやすいボトムとなる。
前部側から脇部にかけて、内生地の傾きが大きくなり、矯正効果を高めることができる。
高齢者向けボトム衣料は、やや弱めの着圧で履き易さを高めることが好ましく、臀部の着圧は5hPa~15hPaが好ましい。臀部の着圧が前記範囲にあることで、履き易さも向上する。
以下、第1の本発明を実施例、比較例により具体的に説明する。尚、実施例、比較例における伸長応力の測定等は下記により行った。
テンシロン引張り試験機を使用し、10cmの把持間隔で把持した2.5cm巾の生地を引張速度300mm/分で伸長率0%~80%の伸長、伸長率80%~0%の回復を3回繰り返し、伸長時荷重、回復時荷重をタテ方向、ヨコ方向それぞれについて測定し、伸長回復曲線を描く。伸長1回目における伸長率50%及び80%の応力を読み取り、タテ方向、ヨコ方向の50%及び80%の伸長荷重とする。製品形態の都合などで把持長が10cmを確保できない場合は可能な把持間隔で行う。幅が2.5cmを確保できない場合は、測定した幅を下記の式にて、2.5cmに変換した値で計算する。
2.5cm幅における伸長荷重[cN]={2.5cm/(測定した生地の幅[cm])}×測定による伸長荷重[cN]
伸長回復率は、タテ方向、ヨコ方向それぞれについて、前記伸長応力測定における伸長回復曲線から3回目の残留伸び(%)を読み取り、下記式:
伸長回復率(%)={[80-(残留伸び)]÷80}×100
によりタテ方向及びヨコ方向の、伸長回復率(%)を算出した。
尚、測定に用いる生地は、接着部や刺繍部等、部分的に伸長応力が高い部分を含まないように、ボトム衣料からサンプリングする。
内生地の身生地と重なっている面積をS(cm2)とし、接着部の面積をS’(cm2)とし、次式:
内生地の中で身生地と接着されていない領域の割合=(S-S’)/S×100(%)
で算出する。
尚、上記面積S及びS’を求められない場合、上記割合は、型紙の面積又は生地の面積に相当するそれぞれ型紙又は生地の重量を求めて、上記式の面積を重量に置き換えて算出する。
内生地下端部の、身生地と非接着の割合は、内生地の着用時に下方向に配置される端部(脇端部は含まない)をP(cm)、着用時に下方向に配置され身生地と接着されている端部をP’(cm)とし、次式:
内生地下端部の身生地と非接着の割合=(P-P’)/P×100(%)
で算出する。
ボトムにおいて、ウエスト部及び左右の脇線、臀溝から囲まれる臀部領域の面積をK(cm2)、本面積内で内生地が存在する面積をK’(cm2)とし、次式:
内生地が臀部を覆う面積割合=K’/K×100(%)
で算出する。
尚、本面積算出時は、Mサイズに対応したマネキンにボトムを着用させて、マネキンの臀部領域K’に対する、ボトムのKを測定した。
標準体型のMサイズのマネキンの左右のヒップトップ(臀部の盛り上がりの頂点)部とお腹(へそ下3cm)にエーエムアイ・テクノ社製着圧測定器AMI-3037-10に接続したエアパックを貼付け、本実施形態のボトム衣料のMサイズを着用させた時の着圧(kPa)を、脱着を3回繰り返し測定し、その平均を求める。
20歳~40歳の被験者5名にボトム衣料を着用させ、HUMAC NORM(CSMi社製)を用いて、仰臥位における股関節と太腿のなす角をニュートラル0°とし、太腿部を上げる形で股関節と太腿のなす角が120°となるまで屈曲させた際に、太腿部中央部における脚上げ時のかかる力をトルクとして測定を実施した。
20歳~40歳の被験者5名にボトム衣料を着用させ、静止立位の状態において、図12に示すように腸骨点、膝蓋骨中央、外果点にて反射マーカーと取り付け、動作解析システム(VINUS3D:株式会社ノビテック製)にて計測を行い、腸骨点、膝蓋骨中央、外果点からなす膝角度(図12で示すΘ:前面から見た膝の内角表す)を測定した。尚、効果の度合いを次式にて算出した。
膝角度Θ[°]=(ボトム衣料着用時の腸骨点、膝蓋骨中央、外果点からなす角度)-(未着用時の腸骨点、膝蓋骨中央、外果点からなす角度)
外旋力が働き、膝が外旋される場合は、Θは負の値となり、内旋力が働き、膝が内旋される場合は、Θは正の値となる。また、Θの絶対値が大きいほど、内旋又は外旋の作用が大きい。
全体の締め付け感、動きやすさ、脚の矯正感について被験者5名で以下の基準で評価し、平均する。
<締め付け感>
5:非常に快適である
4:やや快適である
3:どちらともいえない
2:やや不快である
1:非常に不快である
<動きやすさ>
5:非常に動きやすい
4:動きやすい
3:どちらともいえない
2:やや動きにくい
1:非常に動きにくい
<矯正感>
5:非常に矯正力を感じる
4:矯正力を感じる
3:どちらともいえない
2:やや矯正力を感じる
1:あまりに矯正力を感じない

したがって、本発明のボトム衣料は、動作時において動きやすさを阻害することなく、かつ、膝に対する旋回効果に優れたものとなる。
次に、第2の本発明について、実施例及び比較例を挙げて本実施の形態をより具体的に説明する。しかしながら、本実施の形態は、その要旨から逸脱しない限り、以下の実施例に限定されるものではない。実施例中の物性は以下の方法により測定した。
テンシロン引張り試験機を使用し、10cmの把持間隔で把持した2.5cm巾の生地を引張速度300mm/分で伸長率0%~80%の伸長、伸長率80%~0%の回復を3回繰り返し、伸長時応力、回復時応力をヨコ方向について測定し、伸長回復曲線を描く。伸長1回目における伸長率50%の応力を読み取り、ヨコ方向の50%の伸長応力とする。製品形態の都合などで把持長が10cmを確保できない場合は5cm等の可能な把持間隔で行う。
伸長回復率は、ヨコ方向について前記伸長応力測定における伸長回復曲線から3回目の残留伸び(%)を読み取り、下記式:
伸長回復率(%)={[80-(残留伸び)]÷80}×100
によりタテ方向及びヨコ方向の、伸長回復率(%)を算出した。尚、測定に用いる生地は、接着部や刺繍部等、部分的に伸長応力が高い部分を含まないようにサンプリングする。
(株)キイヤ社製のC70トルソーの脇部(トルソーの脚部脇の縫い合わせ線)において、股部より水平距離で10cm上の点を大転子相当部とする。該トルソーにボトム衣料を着用させた状態で、内生地のタテ方向中央線及び内生地の上端部と、前記大転子相当部とのタテ方向距離を計測する。
ボトム衣料を裏返して机上に置いた状態で、ボトム衣料脇部上の裾部から身生地と内生地との接着部までのタテ方向距離を計測する。ボトム衣料脇部とは、ボトム衣料の前中心と後中心を重ねた状態で、机上にボトム衣料を置いた際に脇線として現れる部位を示す。
(株)キイヤ製のC70サイズの下半身トルソーの左右のヒップトップ(臀部の盛り上がりの頂点)部とお腹(へそ下3cm)にエーエムアイ・テクノ社製着圧測定器AMI-3037-10に接続したエアパックを貼付け、本実施形態のボトム衣料のMサイズを着用させた時の着圧(kPa)を、脱着を3回繰り返し測定し、その平均を求める。
20歳~60歳の被験者5名にボトム衣料を着用させ、1周800mのコースを歩かせた時の時間Tと歩幅Qを計測し、ショ-ツのみを着用した場合の時間T1、歩幅Q1との差を求める。尚、いずれも外衣として被験者ごとに同一の締め付けの無い長パンツとTシャツ、運動靴を着用させる。
歩幅差=Q-Q1(cm)
歩行時間差=T1-T(sec)
20歳~60歳の被験者5名にボトム衣料を着用させ、静止立位の状態において、図12に示すように腸骨点、膝蓋骨中央、外果点にて反射マーカーと取り付け、動作解析システム(VINUS3D:株式会社ノビテック製)にて計測を行い、腸骨点、膝蓋骨中央、外果点からなす膝角度(図12で示すΘ:前面から見た膝の内角表す)を測定する。尚、効果の度合いを次式にて算出する。
膝角度Θ[°]=(ボトム衣料着用時の腸骨点、膝蓋骨中央、外果点からなす角度)-(未着用時の腸骨点、膝蓋骨中央、外果点からなす角度)
外旋力が働き、膝が外旋される場合は、Θは負の値となり、内旋力が働き、膝が内旋される場合は、Θは正の値となる。また、Θの絶対値が大きいほど、内旋又は外旋の作用が大きい。
20歳代の被験者にボトム衣料を着用させてトレッドミル上で12km/hrの速さにて走行させる際、筋電評価装置(Personal-EMG plus:追坂電子機器社製)を用いて大腿直筋、大殿筋、大腿二頭筋の筋活動量Eをそれぞれ測定し、ショ-ツのみを着用した場合の筋活動量E1からの変化の度合いを次式より求める。
平均筋活動量[%CTRL]=(E/E1)×100
尚、立脚期と遊脚期の区別のために、トレッドミル走行の様子は高速度カメラにて撮影し、各筋活動量の値は、走行サイクルにおける立脚期のみを積分して求める。走行3サイクルの筋活動量の平均値をEとする。大腿直筋、大殿筋、大腿二頭筋は下肢の屈曲、伸展に関与する筋群であり、平均筋活動量が大きいときは走行においてエネルギー消費が大きく、反対に平均筋活動量が小さいときは走行においてエネルギー消費が小さく、効率のよい走行ができていると言える。
臀部の締め付け感、動きやすさ、疲労感について被験者5名で以下の基準で評価し、平均する。
<締め付け感>
5:非常に快適である
4:やや快適である
3:どちらともいえない
2:やや不快である
1:非常に不快である
<動きやすさ>
5:非常に動きやすい
4:動きやすい
3:どちらともいえない
2:やや動きにくい
1:非常に動きにくい
<疲労感>
5:非常に疲労感が小さい
4:疲労感が小さい
3:どちらともいえない
2:やや疲労感が大きい
1:非常に疲労感が大きい
