Abstract

The aim of this study was to observe the relationship between time limit at the minimum velocity that elicits maximal oxygen consumption (TLim-v VO2 max) and stroke rate, stroke length, and stroke index. 13 men and 10 women, highly trained swimmers, performed an intermittent incremental test for v VO2 max assessment and an all-out swim to estimate TLim-v VO2 max. The mean +/- SD TLim-v VO2 max, v VO2 max, stroke rate, stroke length, and stroke index values were 233.36 +/- 53.92 sec., 1.40 +/- .06 meter/sec., 35.58 +/- 2.89 cycles/min., 2.39 +/- .22 meter/cycle, and 3.36 +/- .41 meter2/(cycle x sec.), respectively. The correlation between TLim-v VO2 max and stroke rate was -.51 (p < .01), and values for TLim-v VO2 max with stroke length (r = .52, p < .01) and stroke index (r = .45, p < .05). These results seem to suggest that technical skill is a key factor in typical efforts requiring prolonged aerobic power.

摘要

本研究的目的是观察在引起最大摄氧量的最低速度下的时间限制（TLim-v VO2 max）与划水频率、划水长度和划水指数之间的关系。13名男性和10名女性，均为训练有素的游泳运动员，进行了一项用于评估v VO2 max的间歇递增测试以及一次全力游泳以估计TLim-v VO2 max。TLim-v VO2 max、v VO2 max、划水频率、划水长度和划水指数的平均值±标准差分别为233.36±53.92秒、1.40±0.06米/秒、35.58±2.89次/分钟、2.39±0.22米/次和3.36±0.41平方米/（次×秒）。TLim-v VO2 max与划水频率之间的相关性为-0.51（p < 0.01），TLim-v VO2 max与划水长度（r = 0.52，p < 0.01）和划水指数（r = 0.45，p < 0.05）之间的相关性。这些结果似乎表明，在需要长时间有氧能力的典型运动中，技术技能是一个关键因素。
