Group average for exercise intensity achieved over the course of the exercise sessions as indexed by %HRmax (A) and RPE (B). For the HIIT group, data shown represent average exercise intensity at the 2-min mark within each 4-min bout of HIIT exercise. For MCT group, the data indicate average exercise intensity collected at 4 different timepoints within the each MCT session (i.e., at 5, 10, 20, and 25 min during the main MCT component, i.e., after 5 to 10 min of warm-up). %HRmax, percentage of maximum heart rate; RPE, rating of perceived exertion; HIIT, high-intensity interval training; MCT, moderate-intensity continuous training.
