筋力トレーニングに対する加圧の効果

摘要

筋力の向上はスポーツ選手にとって不可欠のものでrnある．現在さまざまなスポーツ現場で行われているレrnジスタンストレーニングは筋肥大，筋力向上のためにrn効果的な方法であるが，筋肥大を引き起こすためにはrn1RM（repetition max，最大挙上筋力）の65%以上の強rn度が必要であり（Campos et al．2002；Kraemeret al．rn2004；McDonagh et al．1984），さらに筋肥大が生じるrnには通常3，4ケ月の期間が必要であるとされているrn（Jones and Rutherford 1987；Staron et al．1994；Abe et al．rn2000）．%KAATSU-training with lower intensity and loading is considered to have significant effects on our skeletal muscles. In this study, ten-healthy University male students were performed two times of muscular training with the same volume, frequency, intensity, and period with or without KAATSU, to estimate the effects of KAATSU on muscle power and muscle volume and area. Following the training with KAATSU performed by 20% of 1 repetition maximum for 4 weeks, the increases in cross-sectional area and the volume were observed in upper-arm muscles, as well as the increase in muscle strength. In contrast, those changes could not be obtained following the training without the KAATSU. The results indicate that the muscular training with KAATSU is useful for increase the muscle power and volume, even in lower loading and short period.
