内容 本研究はセルフレジスタンストレーニング(SRT)の主観的強度の違いが生体に与える影響について検討した。今回は最大の強さ100SRTと100SRTの50%強度の50SRTを設定した。実験は40秒のSRT(右腕10回, 左腕10回)を間に20秒の休息を挟んで5回行った。心拍数は50SRTと100SRTの間で有意な差が観察された。呼吸商は実験を通じて50SRTと100SRT状態の間に有意な差が見られた。酸素消費量, EMGは実験を通じて50SRTと100SRTの間に有意な差が観察された。血中乳酸濃度は50SRTではほとんど変化しなかったが, 100SRTでは試技後に大きく増加した。結論として, SRTは生体に与える負荷強度を意識的にコントロールすることが可能であり, SRTがトレーニングだけでなく, リハビリテーションを目的としても利用することが可能であることが示された。
We have previously identified self-resistance training (SRT) as an acceptable alternative to resistance training modalities. In the present study we investigate the relationships between subjective intensity SRT and changes in oxygen consumption, respiratory quotient, heart rate, blood lactate concentration, and electromyography. We employed two intensities: maximal intensity SRT (100SRT)and 500f maximal intensity SRT (50SRT)each applied for five 40-sec periods of activity with 20 sec of rest between periods. Each subject performed 5 sets of the 100SRT condition, followed by a 60-minute rest period, and then 5 sets of the 50SRT condition. The results obtained in this study were as follows: 1. Although heart rate was not significantly elevated from rest during 50SRT, significant differences were observed among each exercise period and among each rest period during the 100SRT condition compared to rest. For each set, differences between the 50SRT and 100SRT conditions were statistically significant. 2. Respiratory quotient (RQ) was significantly different between 50SRT and 100SRT conditions in each set throughout the experiment. In the 100SRT condition, RQ was significantly increased compared with the value at E 1. On the other hand, in the 50SRT condition only the El vs. E3 difference was statistically significant. The RQ in the 50SRT condition remained relatively constant at around 0.8, but increased to values greater than 1.0 after the 2nd set in the 100SRT condition. 3. With the exception of the first set significant differences in oxygen consumption were observed between 50 SRT and 100SRT for each set throughout the experiment. Oxygen consumption during the 100SRT condition increased significantly above E1 for each of the subsequent 4 sets. 4. There were significant differences between the EMG response to 50SRT and 100SRT in each set. Although significant differences were found in the 100SRT condition (right M. Biceps brachii: E1 vs. E2 and E1 vs. E3; left M. Triceps brachii: E4 vs. E5), there were no signif
