- Abstract
Adults engage in exercise programs not only to improve health, but also to lose or maintain body fat mass. There is the tendency for subjects to exercise at a self-selected a pace rather than a prescribed intensity. The purpose of this study was to determine if sedentary women could self-select a walking intensity that corresponds to Fatmax. This study consisted of 22 adult women with an average age of 42.91 ± 44 y rs. Each subject performed a maximal incremental test to exhaustion and a session of exercise at their self-selected walking pace. Data from the maximal test were used to determine Fatmax and Fatzone. The t test was used to determine differences between the subjects' self-selected walking pace and the predicted walking speed at Fatmax. Fatmax occurred at 51.3 ± 7.2% of VO2 max and Fatzone between 46% and 56% of VO2 max. The intensity of the self-selected walking pace was 5.06 ± 0.65 km·h-1, which corresponded to 51.3% VO2 max and to 66.8% HR max. These findings indicate that sedentary women can self-select a walking intensity that corresponds to an exercise intensity that elicits maximal fat oxidation (Fatmax).
