We evaluated a short-duration maximum exercise test by comparing a 15-s incremental exercise protocol with a 1-min incremental method. Twenty normal men and women were studied using cycle and/or treadmill ergometry. In subjects tested on both exercise devices, anaerobic threshold and maximal oxygen uptake (VO2max) were higher for both protocols on the treadmill than on the cycle ergometer (P less than 0.001). However, when the 15-s and 1-min tests were compared using the same device (treadmill or cycle), there were no significant differences between protocols in anaerobic threshold or maximum exercise values of minute ventilation, respiratory rate, tidal volume, VO2max, oxygen pulse, and peak expiratory flow rate. Linear regression analyses indicated differences between the 15-s and 1-min protocols when cardiopulmonary measurements were related to power; however, the two protocols were comparable when cardiopulmonary data were related to oxygen uptake. Comparisons between protocols or between exercise devices were not systematically different in large vs small individuals, or in men vs women. Short-duration incremental exercise tests appear to be reliable, practical methods for assessing exercise performance in normal individuals.
我们通过比较15秒递增运动方案和1分钟递增方法，评估了一种短时长最大运动测试。使用自行车和/或跑步机测力计对20名正常男性和女性进行了研究。在两种运动设备上都接受测试的受试者中，跑步机上两种方案的无氧阈和最大摄氧量（VO2max）均高于自行车测力计（P<0.001）。然而，当使用相同设备（跑步机或自行车）比较15秒和1分钟测试时，两种方案在无氧阈或分钟通气量、呼吸频率、潮气量、VO2max、氧脉搏和呼气峰值流速的最大运动值方面没有显著差异。线性回归分析表明，当心肺测量值与功率相关时，15秒和1分钟方案之间存在差异；然而，当心肺数据与摄氧量相关时，两种方案具有可比性。方案之间或运动设备之间的比较在体型大小不同的个体或男性与女性之间没有系统性差异。短时长递增运动测试似乎是评估正常个体运动表现的可靠、实用方法。
