最大下泳速度におけるフロントクロールおよびブレストストロークの経済性について

抄録

The purpose of this study was to compare the energy expenditure during submaximal front crawl (Fr) and breast stroke (Br) swimming. Six male college swimmers performed submaximal and maximal exercise tests in both styles in a swimming flume. In submaximal exercise tests, they swam at the following given velocities for 5 min, Br : 0.3, 0.5 and 0.7 m/sec ; Fr : 0.3, 0.5. 0.7 and 0.9 m/sec. In maximal exercise tests, following submaximal swimming at 0.9 m/sec in Br and 1.1 m/sec in Fr, swimming velocity was increased progressively by 0.1 m/sec every I min until the subjects reached to voluntary exhaustion. Vo_2max obtained from the maximal swimming tests in Br and Fr were 4.27 and 4.18 l/min, respctively. And there was no significant difference between these two values.
