Data are means ± SD. *Significant main effect of training status (P < 0.05), and post hoc analysis identifying significant difference from Pretraining. BMI, body mass index; f, female; HIIT, high-intensity interval training; m, male; MICT, moderate-intensity continuous training; NEFA, nonesterified fatty acid; V̇o_2peak, peak oxygen uptake rate.
