The purpose of this study was to establish reproducible assessments of cardiopulmonary responses to exercise using a computer-interfaced isokinetic swim bench. Five male and four female highly trained swimmers with mean age of 19.2 +/- 1.2 (yrs), stature 1.75 +/- 0.02 (m) and body mass of 65.8 +/- 2.9 (kg) performed an incremental exercise test on two occasions within one week. Oxygen consumption (VO(2)), heart rate (HR) and exercise intensity were recorded throughout the exercise test. Measurements were made of the peak oxygen consumption (VO(2peak)), peak heart rate (HR(peak)) peak exercise intensity (EI(peak)) and the submaximal heart rate vs exercise intensity (HR/EI) and oxygen consumption vs exercise intensity (VO(2)/EI) relationships. The values for VO(2peak), HR(peak) and EI(peak) from all tests were 2.85 +/- 0.26 (I.min(-1)), 171 +/- 2.8 (b.min(-1)) and 86.2 +/- 6.8 (watts) respectively. The differences in these peak values from repeated tests were 0.06 I.min(-1), 1.8 b.min(-1) and 1.3 W, which were not significant (p > 0.05; paired t-test). These represented 2.1, 1.0 and 1.5% respectively. The HR/EI and VO(2)/EI relationships were shown to be linear (at least r = 0.99 and r = 0.98 respectively) and the differences in these relationships from repeated tests were not significant (p > 0.05, ANCOVA) showing adjusted mean differences of 0.02 I.min(-1) and 0.5 b.min(-1) for the group. These results suggest that this method, which uses a swim bench, provides reproducible measurement of the cardiopulmonary responses to exercise in swimmers.
本研究的目的是使用计算机接口的等动游泳训练台，建立对运动心肺反应的可重复评估。五名男性和四名女性高水平游泳运动员，平均年龄为19.2±1.2（岁），身高1.75±0.02（米），体重65.8±2.9（千克），在一周内分两次进行递增运动测试。在整个运动测试过程中记录耗氧量（VO₂）、心率（HR）和运动强度。测量了峰值耗氧量（VO₂peak）、峰值心率（HRpeak）、峰值运动强度（EIpeak）以及次最大心率与运动强度（HR/EI）和耗氧量与运动强度（VO₂/EI）的关系。所有测试的VO₂peak、HRpeak和EIpeak值分别为2.85±0.26（升·分钟⁻¹）、171±2.8（次·分钟⁻¹）和86.2±6.8（瓦）。重复测试这些峰值的差异分别为0.06升·分钟⁻¹、1.8次·分钟⁻¹和1.3瓦，差异不显著（p>0.05；配对t检验）。这些差异分别占2.1%、1.0%和1.5%。HR/EI和VO₂/EI关系呈线性（分别至少r = 0.99和r = 0.98），重复测试这些关系的差异不显著（p>0.05，协方差分析），该组的调整后平均差异为0.02升·分钟⁻¹和0.5次·分钟⁻¹。这些结果表明，这种使用游泳训练台的方法，能够对游泳运动员运动时的心肺反应进行可重复测量。
