This study evaluated the predictive ability of the modified Canadian Aerobic Fitness Test (mCAFT) on an independent sample of subjects and compared it to the original Canadian Aerobic Fitness Test (CAFT). Male and female subjects (n = 154), 15-69 yrs of age, performed the mCAFT and a maximal treadmill test. VO2max scores predicted from the mCAFT equation did not differ significantly from those measured during the treadmill test, whether the sample was analysed overall or categorized by sex, whereas the CAFT (Jetté) equation resulted in VO2max scores that were significantly lower than either the measured values or those predicted using the mCAFT. The strength of the linear relationship between predicted and measured VO2max scores is the same for both the mCAFT (r = 0.88) and CAFT (r = 0.89). However, the mCAFT results in a lower mean square error (37.0 for mCAFT vs. 63.3 for CAFT) and thus is an improvement over the CAFT prediction.
本研究评估了改良的加拿大有氧适能测试（mCAFT）对独立样本受试者的预测能力，并将其与原始的加拿大有氧适能测试（CAFT）进行比较。15至69岁的男性和女性受试者（n = 154）进行了mCAFT和最大跑步机测试。无论对样本进行整体分析还是按性别分类，由mCAFT方程预测的最大摄氧量（VO2max）得分与跑步机测试期间测得的得分无显著差异，而CAFT（杰特）方程得出的VO2max得分显著低于测量值或使用mCAFT预测的值。mCAFT（r = 0.88）和CAFT（r = 0.89）预测的VO2max得分与测量得分之间的线性关系强度相同。然而，mCAFT的均方误差较低（mCAFT为37.0，CAFT为63.3），因此在预测方面比CAFT有所改进。
