The exercise intervention consisted of both aerobic and anaerobic exercise training for 60 minutes, twice a week for 24 weeks. Values are medians of fraction of time spent at each level of activity using an accelerometer. A Wilcoxon signed rank test was used to determine differences between pre- and postintervention followed by a Mann–Whitney test for between-group differences, with and , respectively. Effect sizes (ES) were calculated using the equation r = Z/√N. SED, sedentary activity level; LIGHT, light activity level; MOD, moderate activity level; VIG, vigorous activity level.
