本研究的目的是确定使用新型游泳训练机进行增量全身锻炼时肢体功率输出和心肺反应的可重复性。 8 名平均年龄为 23.7 +/- 4.6（岁）、身高 1.77 +/- 0.13（米）、体重为 74.7 +/- 2.8（公斤）的游泳运动员给予知情同意，并参加了机器上的重复运动测试。所有受试者均使用前爬运动进行 2 次增量运动测试，直至力竭。根据这些测试，确定了峰值耗氧量 (VO2peak)、峰值心率 (HRpeak)、峰值功率输出 (W-peak) 和个体肢体功率输出。结果显示，对于力竭时的任何变量，测试 1 和 2 之间没有显着差异，CV% 范围为 2.8% 至 3.4%。汇总平均值为： b. VO2peak 3.7 +/- 0.65 L.min(-1)，HRpeak 178.7 +/- 6.6 min(-1) 和 W 峰值 349.7 +/- 16.5 W。腿部和手臂对总功率输出的平均贡献分别为（分别为 37.3 +/- 4.1 % 和 62.7 +/- 5.1 %）。这些结果表明，使用该训练机在一定范围的运动强度下进行全身运动时，可以重复测量各个肢体的功率输出和心肺参数。
The purpose of this study was to determine the reproducibility of limb power outputs and cardio pulmonary responses, to incremental whole-body exercise using a novel swimming training machine. 8 swimmers with a mean age of 23.7 +/- 4.6 (yrs), stature 1.77 +/- 0.13 (m) and body mass of 74.7 +/- 2.8 (kg) gave informed consent and participated in repeat exercise testing on the machine. All subjects performed 2 incremental exercise tests to exhaustion using front crawl movements. From these tests peak oxygen consumption (VO2peak), peak heart rate (HRpeak), peak power output (W-peak) and individual limb power outputs were determined. Results showed there were no significant differences between test 1 and 2 for any variable at exhaustion, and the CV % ranged from 2.8 to 3.4 %. The pooled mean values were; VO2peak 3.7 +/- 0.65 L. min(-1), HRpeak 178.7 +/- 6.6 b. min(-1) and W-peak 349.7 +/- 16.5 W. The mean contributions to the total power output from the legs and arms were (37.3 +/- 4.1 % and 62.7 +/- 5.1 % respectively). These results show that it is possible to measure individual limb power outputs and cardopulmonary parameters reproducibly during whole-body exercise using this training machine, at a range of exercise intensities.
