Changes in fitness and cardiometabolic parameters (mean [SD]) before and 1 month following intervention for study participants randomized to high-intensity interval training (HIIT, n = 10) and moderate-intensity continuous exercise (MICT, n = 16) and overall (n = 26) effect of time. The current results represent per-protocol analysis.
