〔目的〕筋力増強を目的とする筋への電気刺激と同時にその拮抗筋の求心性収縮により生じる遠心性収縮を利用した筋力増強法の効果について大腿四頭筋を対象に検討することである。〔対象〕健常成人20名を対象とした。〔方法〕低周波電気刺激を内側広筋大腿直筋外側広筋に与え膝関節の屈曲運動によって生じる遠心性収縮を利用した筋力トレーニングを20分間/回週3回4週間行った。測定項目を大腿四頭筋力と大腿周囲径としトレーニング前2および4週間後に測定した。〔結果〕大腿四頭筋力は2週間後に22.94週間後に44.3に増加し大腿周囲径は4週間後に有意に増加した。〔結語〕本法は関節運動を利用した筋力増強法であり簡便な電気刺激装置を用いているため臨床の理学療法に幅広く利用可能と考えられた。Purpose: This study investigated the effect of muscular strength reinforcement through electrical stimulation and eccentric contraction. [Subjects] The subjects were 20 healthy volunteers. [Methods] Low frequency electric stimulation was given to the vastus medialis, rectus femoris, vastus lateralis and a muscular exercise of eccentric contraction by flexure exercise of the knee joint was performed. Subjects trained for 20 minutes 3 times a week for 4 weeks. The quadriceps femoris muscle strength and thigh circumference diameter were measured at the beginning the exercise, and two and four weeks later. [Results] The quadriceps femoris muscle strength increased significantly by 22.9% two weeks later, and 44.3% four weeks later in comparison with the beginning the exercise. In addition, the thigh circumference diameter increased significantly four weeks later. [Conclusion] This method using a joint movement was an effective exercise method for the muscular strength reinforcement
