 note = {本研究の目的は，高齢者を対象に6週間のカーフレイズエクササイズの介入が足関節底屈時のelectromechanical delay (EMD)，筋出力，歩行能力に及ぼす影響について検討することである。被験者は，本研究に対するインフォームド・コンセントを行い賛同を得た健康な女性高齢者25名(平均年齢75.2±5.6歳)を対象とした。カーフレイズエクササイズの介入期間は6週間とし，1日当たり5セット，週3回実施した。足関節底屈のEMD，筋出カの測定は筋力測定装置(KinCom500H)を使用し伸張性筋活動時の条件下において行った。歩行能力は，側方より2次元撮影により5mの区間の測定を行った。主な結果として，介入後におけるEMD，総反応時間，ピークトルク値は，介入前の値より有意に向上していた(EMD:pre 9.9±10.5msec, post 63.1±7.1msec; total reaction time: pre 300.1±56.7msec, post 264.8±38.2msec; peak torque value: pre 50.0±18.9 Nm, post 62.9±12.2 Nm)。しかしながら，歩行飽カ(ストライド，ピッチ，最大歩行速度，普通歩行速度)に介入前と介入後では有意な変化は見られなかった。これらの結果から，カーフレイズエクササイズは下腿三頭筋の機能の改善には効果的であることが示唆された。しかし，歩行館カに効果がなかったことに関しては，おそらく膝関節と股関節の機能で抑制が生じた可能性が推測される。, Ankle plantar flexion is important in the two phases of mid and terminal stances in walking. However, this function is thought to decrease with aging. The purpose of this study was to investigate the effect that calf-raising exercise intervention had on older adults in electromechanical delay (EMD), muscle strength of ankle plantar flexion and walking performances.A group of 25 healthy older women participants (mean age: 75.2 ± 5.6years) were informed and consented to participate in this experiment. The intervention was performed for six weeks (10 X five sets per day, three times a week). The measurements of EMD and muscle strength in ankle plantar flexion were performed by using a dynamometer (KinCom 500H) during eccentric muscle actions. The start of reaction indicated by EMD was measured in proprio-ceptor response of the plantar. The walking performance was measured by two-dimensional photography taken from the side. The result showed significant improvement in post values of the EMD, total reaction time, and peak torque value compared to the pre values (EMD: pre 69.9±10.5 msec, post 63.1±7.1msec; total reaction time: pre 300.1±56.7msec, post 264.8±38.2msec; peak torque value: pre 50.0±18.9 Nm, post 62.9±12.2Nm). However, no significant differences were observed between the pre and post stride, pitch, maximum walking velocity, and normal walking velocity parameters. Basically, the calf-raising exercise was effective for the functional recovery of the triceps surae. As to the ineffectiveness on walking performance, this could be explained by functional restriction of knee and hip joints., application/pdf},
