Values are presented as mean ± SD; LV-HIIT, low-volume high-intensity interval training; RPE, rating of perceived exertion; RER, respiratory exchange ratio; ES, effect size (Cohen’s d
z); ES < 0.2 reflects a trivial effect, ≥ 0.2 and < 0.6 reflects a small effect, ≥ 0.6 and < 1.2 reflects a moderate effect, ≥ 1.2 and < 2.0 reflects a large effect, ≥ 2.0 and < 4.0 reflects a very large effect, and ≥ 4.0 reflects a nearly perfect effect.
