| Popis: | The purpose of the present study was to increase the accuracy of prediction of [Formula: see text] 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, [Formula: see text] (ml∙kg−1∙min−1) = 32.0 + 16.0 [Formula: see text] Age − 0.17 Wt (R2 − 0.77; δ2 − 26.6), where [Formula: see text] = oxygen cost of stepping at the final level (L∙min−1), Age = age (yrs), and Wt = body mass (kg). Key words: exercise test, oxygen consumption, predictive value of tests, physical fitness, epidemiologic methods |
