The purpose of this study was to determine the reproducibility of limb power outputs and cardiopulmonary 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 (VO(₂peak)), peak heart rate (HR(peak)), 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; VO(₂peak) 3.7 ± 0.65 L.min⁻¹, HR (peak) 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 cardiopulmonary parameters reproducibly during whole-body exercise using this training machine, at a range of exercise intensities.
本研究旨在确定使用新型游泳训练机进行递增全身运动时肢体功率输出和心肺反应的可重复性。8 名年龄均为 23.7±4.6（岁）、身高 1.77±0.13（米）和体重 74.7±2.8（千克）的游泳运动员，经知情同意后，在机器上重复进行运动测试。所有受试者均采用自由泳进行 2 次递增运动至力竭测试。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。结果表明，在力竭时，任何变量在测试 1 和 2 之间均无显著差异，CV%范围为 2.8%至 3.4%。汇总平均值为：VO₂peak 3.7±0.65 L.min⁻¹，HRpeak 178.7±6.6 b.min⁻¹和 W（peak）349.7±16.5 W。腿部和手臂对总功率输出的平均贡献分别为（37.3±4.1%和 62.7±5.1%）。这些结果表明，使用该训练机在一系列运动强度下进行全身运动时，可以重复测量个体肢体功率输出和心肺参数。
