ステップエクササイズにおける下肢筋の筋電図学的分析

Abstract

The purpose of this study was to determine the effects of movement speed during stepping machine exercise on the muscle activity of the lower extremities. Nine healthy subjects with a mean age of 24.3 years, participated in this study. Electromyographic muscle activity during stepping exercise was measured in the rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semimembranosus, gastrocnemius and tibialis anterior. Stepping exercise was performed at three different speeds (80, 100, 120m/min). There was a significant difference in muscle activities of all muscles at the different movement speeds, however, muscle activities were low, at less than 30 percent. The results indicate that exercise on the stepping machine is an appropriate exercise for improving muscle endurance and conditioning of the lower extremities.
