The purpose of the present study was to increase the accuracy of prediction of VO2max from the Canadian Aerobic Fitness Test (CAFT) by modifying the protocol and developing a new equation. Males and females between the ages of 15 and 69 years (n = 129) were tested on four occasions. Each subject performed four submaximal step tests (modified CAFT protocol) and a maximal treadmill test. The modification of the protocol consisted of allowing each subject to complete the number of stages needed to reach a target heart rate of 85% of age-predicted maximum. This required adding a new Stage 8 for men and Stages 7 and 8 for women. The prediction equation resulting from regression analysis was, VO2max (ml.kg-1 x min-1) = 32.0 + 16.0 VO2 - 0.24 Age - 0.17 Wt (R2 - 0.77; delta 2 - 26.6), where VO2 = oxygen cost of stepping at the final level (L.min-1), Age = age (yrs), and Wt = body mass (kg).
本研究的目的是通过修改测试方案并开发一个新方程，提高加拿大有氧适能测试（CAFT）对最大摄氧量（VO2max）预测的准确性。对15至69岁的男性和女性（n = 129）进行了四次测试。每位受试者进行了四次次最大强度台阶测试（修改后的CAFT方案）和一次最大强度跑步机测试。方案的修改包括允许每位受试者完成达到年龄预测最大心率85%的目标心率所需的台阶数。这需要为男性增加一个新的第8阶段，为女性增加第7和第8阶段。回归分析得出的预测方程为，VO2max（毫升·千克⁻¹·分钟⁻¹）= 32.0 + 16.0 VO2 - 0.24年龄 - 0.17体重（R² = 0.77；δ² = 26.6），其中VO2 = 最后一级台阶的摄氧量（升·分钟⁻¹），年龄 = 年龄（岁），体重 = 体重（千克）。
