Outcome Measure Changesa
↵a Data are presented as mean (SD) or mean (95% confidence interval [CI]) and are from unadjusted mixed effects models. Ventilatory threshold was not identifiable for one participant. Metabolic cost of gait was not obtained for 2 participants due to air leaking during baseline testing. Within group change (Δ) scores are from time contrasts. Between-group differences in change are from group × time interaction contrasts. Standardized effect sizes were calculated by dividing the between-group difference in mean improvement by the standard deviation of change. HIT=high-intensity interval training, MCT=moderate-intensity continuous training, V̇o2peak=peak oxygen consumption.
