The purpose of this study was 1) to compare the maximal oxygen uptake (VO2max) obtained in swimmers during tethered swimming, free swimming, and flume swimming, and 2) to determine whether an arm-ergometer test would provide comparable results. In the first experiments the VO2max for tethered swimming (2.67 +/- 0.26 l/min) and flume swimming (2.62 +/- 0.26 l/min) were not different (P greater than 0.05) and were highly correlated (r = 0.99). However, with arm ergometry a significantly lower VO2max (2.36 +/- 0.24 l/min) occurred from those found in the two swimming tests (P less than 0.05). Other experiments demonstrated that the tethered swimming VO2max (3.53 +/- 0.27 l/min) and the free swimming VO2max (3.55 +/- 0.28 l/min) also provide results that were similar (P greater than 0.05) and highly correlated with each other (r = 0.99). Differences between tethered and flume swimming, and tethered and free swimming were small, being 1.2 +/- 1.6% and 0.6 +/- 0.9%, respectively. Differences between tethered swimming and arm ergometry VO2max were large, 14.7 +/- 2.4%, despite the high correlation (r = 0.97) between these measurements. Predictions of a swimming VO2max from the arm-ergometer data yielded a considerable error (+/-7.1% and +/-7.4%). The present results indicate that flume swimming, free swimming, and tethered swimming yield essentially identical VO2max results.
1）比较游泳者在系绳游泳、自由游泳和水槽游泳过程中获得的最大摄氧量（VO2max）；2）确定手臂测力计测试是否能提供可比的结果。在首次实验中，系绳游泳（2.67±0.26升/分钟）和水槽游泳（2.62±0.26升/分钟）的VO2max没有差异（P＞0.05），且高度相关（r = 0.99）。然而，使用手臂测力计测得的VO2max（2.36±0.24升/分钟）明显低于两项游泳测试中的结果（P＜0.05）。其他实验表明，系绳游泳的VO2max（3.53±0.27升/分钟）和自由游泳的VO2max（3.55±0.28升/分钟）也相似（P＞0.05），且彼此高度相关（r = 0.99）。系绳游泳与水槽游泳、系绳游泳与自由游泳之间的差异较小，分别为1.2±1.6%和0.6±0.9%。尽管系绳游泳与手臂测力计测量的VO2max之间相关性较高（r = 0.97），但两者之间的差异较大，为14.7±2.4%。根据手臂测力计数据预测游泳VO2max会产生相当大的误差（±7.1%和±7.4%）。目前的结果表明，水槽游泳、自由游泳和系绳游泳产生的VO2max结果基本相同。
