Our purpose was to assess the validity of VO2 max values predicted from The Canadian Aerobic Fitness Test (CAFT) by comparing them with peak VO2 values measured during a maximal treadmill protocol. Male and female subjects, 15-69 yr (n = 129), performed two submaximal exercise tests (CAFT protocol), and one maximal treadmill test. There was no significant heart rate habituation between the first two CAFT protocols. Peak VO2 values measured during the treadmill test (TM) were significantly higher than those predicted from the CAFT whether the sample was analyzed overall or categorized by sex. When the sample was categorized by age group, all but groups 1 (15-19) and 6 (60-69) had treadmill peak VO2 values significantly higher than those predicted using Jetté's equation. Using treadmill measured peak VO2 scores as the gold standard, VO2 max predictions using the CAFT protocol and Jetté equation placed individuals of lower fitness levels more accurately than highly fit individuals, into one of five fitness categories.
我们的目的是通过将《加拿大有氧适能测试》（CAFT）预测的最大摄氧量（VO2 max）值与在最大跑步机测试方案中测得的峰值VO2值进行比较，来评估其有效性。15至69岁的男性和女性受试者（n = 129）进行了两次亚极量运动测试（CAFT方案）和一次最大跑步机测试。在前两个CAFT方案之间，心率没有明显的适应性变化。无论样本是整体分析还是按性别分类，跑步机测试（TM）期间测得的峰值VO2值均显著高于CAFT预测的值。当按年龄组对样本进行分类时，除了第1组（15 - 19岁）和第6组（60 - 69岁）外，所有组的跑步机峰值VO2值均显著高于使用杰特方程预测的值。以跑步机测得的峰值VO2分数作为金标准，使用CAFT方案和杰特方程预测的VO2 max将较低健康水平的个体比高健康水平的个体更准确地归入五个健康类别之一。
