The purpose of this study was to select a maximal aerobic power test protocol with which to validate a submaximal step test prediction equation. Subjects (N = 129), males and females 15 to 69 years of age, performed one maximal step test and one maximal treadmill test. The maximal treadmill protocol yielded higher peak VO2, ventilation, heart rate, and RER values. An age-predicted maximum heart rate was achieved by 35% of subjects on the step test and 55% on the treadmill. An RER of 1.15 was attained by 22% of the subjects on the step test and 53% on the treadmill. Regression analysis indicated that the submaximal test was more predictive of VO2max when the maximum was attained using the treadmill rather than the maximal step protocol. Peak VO2 values obtained from subjects tested on the treadmill will be used to develop a new prediction equation for the Canadian Aerobic Fitness Test.
本研究的目的是选择一种最大有氧功率测试方案，用以验证次最大台阶测试预测方程。受试者（N = 129），年龄在15至69岁之间的男性和女性，进行了一次最大台阶测试和一次最大跑步机测试。最大跑步机测试方案产生了更高的峰值摄氧量、通气量、心率和呼吸交换率值。在台阶测试中，35%的受试者达到了年龄预测的最大心率，在跑步机测试中这一比例为55%。在台阶测试中，22%的受试者呼吸交换率达到1.15，在跑步机测试中这一比例为53%。回归分析表明，当使用跑步机而非最大台阶测试方案达到最大值时，次最大测试对最大摄氧量的预测性更强。从跑步机测试的受试者获得的峰值摄氧量值将用于开发加拿大有氧适能测试的新预测方程。
