〔目的〕本研究では,足趾把持筋力トレーニングが最大速度歩行の床反力に及ぼす影響を検討することを目的とした。〔対象〕健常な学生27名とした。〔方法〕対象者を男女別に無作為にトレーニング群,対照群に振り分けた。足趾把持筋力,10 m最大速度歩行時の速度,歩数,歩行率,歩幅,最大速度歩行時の床反力を介入期間の前と後に測定した。トレーニング群には4週間の足趾把持筋力トレーニングを行わせ,対照群には普段通りの生活をさせた。〔結果〕トレーニング群は有意に足趾把持筋力が増強し,10 m最大歩行速度が速くなった。また,床反力横方向第3波,歩行率において増加傾向がみられた。〔結語〕蹴り出しにおける脚の運びの方向性が適正化することで,歩行率が改善し,最大歩行速度が向上する可能性が示唆された。また,最大歩行速度向上に対して床反力垂直方向の最大波に増加がみられなかったことから,足趾による制動力が高まったことでソフトに踵接地でき,踵接地による衝撃が減少したことが示唆された。

Mean step-count at home was most strongly affected by ankle plantar flexion strength/kg, and increasing ankle plantAR flexionstrength/kg was shown to promote recovery of normal physical activities. Expand


Effects of age and gender on toe flexor muscle strength.
Toe flexor muscle strength decreased significantly with age, which decrement underlies the known age-related reduction in the functional base of support. Expand
Plantarflexion Strength of the Toes: Age and Gender Differences and Evaluation of a Clinical Screening Test
The findings indicate that aging is associated with reduced plantarflexion strength of the toes and the paper grip test may be a useful screening tool to detect toe weakness in the clinical setting. Expand
Development of an exercise program for fall prevention for elderly persons in a long‐term care facility
The exercise program was shown to be acceptable to use for the prevention of falls among elderly individuals in a long-term care facility and showed increased balance, maintained mobility, and showed a decreased number of fallers and falls, although the muscle strength and fall efficacy did not increase.
