 note = {本研究の目的は,下腿回旋位を変化させた場合の等速性膝関節伸展筋力を比較するとともに,カッティング動作能力との関連について検討することである.若年健常女性23名を対象に,等速性膝関節伸展筋力とカッティング動作課題遂行能力を測定した.等速性膝関節伸展筋力の測定は,下腿内旋位,中間位,外旋位の3条件で,60,180,300deg/secの角速度にて行った.カッティング動作課題遂行能力は,サイドステップカッティングとクロスオーバーカッティングの2条件で測定し,遂行時間を指標とした.膝関節伸展筋力は下腿回旋3条件間で,Peak Torque, Peak Torque/Body Weightに有意差はなく,max Repetition Workも60deg/secで下腿回旋位よりも中間位で有意な高値が示されたのみであった.サイドステップカッティング動作とクロスオーバーカッティング動作との課題遂行時間間には,r=0.886の相関関係が示された.筋力と動作との関係は,全測定条件・採用した3つのパラメータ全てで相関を認めなかった.結果より,2種のカッティング動作課題は,独立した別個の能力を表現するのではなく,下腿回旋位別筋力単変量のみでは説明できないことが示唆された., The purpose of this study is to compare the isokinetic strength of knee extension in different lower leg rotation positions, and investigate the relationship between them and cutting movement ability. Twenty three able-bodied young women participated in the study. We measured the isokinetic strength of knee extension and cutting movement task performance ability. The former measurement was carried out by combining three leg positions (internal rotation, neutral and external rotation) and three angular velocities (60, 180, 300deg/sec). The evaluation of cutting movement task performance ability was determined by measuring sidestep cutting and crossover cutting indexed by execution time. As for knee extension strength, the measurement values revealed no significant differences in peak torque and peak torque/body weight for any angular velocity due to changes in leg rotation position. In maximal repetition work, there were similarly no significant differences, except that 60deg/sec in leg neutral position returned a higher value than internal and external rotation position. There was positive correlation between the task performance times of sidestep cutting and crossover cutting movement (r=0.886). A relationship was not detected between physical strength and movement in all three parameters measured. The results suggest that two cutting movement tasks do not imply independent ability separately, hence cannot be explained by only a mono-variable such as muscle strength for each leg rotation position.},
