Abstract

In this study we compared cardiopulmonary responses to upper-body exercise in 12 swimmers, using simulation of the front-crawl arm-pulling action on a computer-interfaced isokinetic swim bench and arm cranking on a modified cycle ergometer. Subjects adopted a prone posture; exercise was initially set at 20 W and subsequently increased by 10 W. min(-1). The tests were performed in a randomised order at the same time of day, within 72 h. The highest (peak) oxygen consumption (VO(2peak)), heart rate (HR(peak)), blood lactate ([la(-)](peak)) and exercise intensity (EI(peak)) were recorded at exhaustion. Mean (SEM) peak responses to simulated swimming were higher than those to arm cranking for VO(2peak) [2.9 (0.2) vs 2.4 (0.1) l x min(-1); P = 0.01], HR(peak) [174 (2) vs 161 (2) beats x min(-1); P = 0.03], and EI(peak) [122 (6) vs 102 (5) W; P = 0.02]. However, there were no significant differences in [la(-)](peak) [9.6 (0.6) vs 8.2 (0.6) mmol x l(-1); P = 0.08]. Thus simulated swimming is the preferred form of dry-land ergometry for the assessment of swimmers.

竞技游泳运动员两种旱地上肢运动测试方式心肺反应的比较。
在这项研究中,我们比较了12名游泳者在上肢运动时的心肺反应,在计算机界面的等速游泳长凳上模拟前爬泳手臂拉臂动作,在改进的自行车测力仪上模拟手臂转动。受试者采用俯卧姿势;运动最初设定为20 W,随后增加10 W min(-1)。在一天中的同一时间,在72小时内按随机顺序进行试验。在精疲力竭时记录最高(峰值)耗氧量(VO(2peak))、心率(HR(peak))、血乳酸([la(-)](peak))和运动强度(EI(peak))。模拟游泳的平均(SEM)峰反应高于VO(2峰)的手臂曲柄反应[2.9 (0.2)vs 2.4 (0.1) l x min(-1)];P = 0.01], HR(峰值)[174 (2)vs 161(2)次× min(-1)];P = 0.03], EI(峰值)[122 (6)vs 102 (5) W;P = 0.02]。然而,[la(-)](峰值)[9.6 (0.6)vs 8.2 (0.6) mmol x l(-1)]无显著差异;P = 0.08]。因此,模拟游泳是旱地几何学评估游泳者的首选形式。
