Physical training protocol. 1xHIIT: High-Intensity Interval Training performed in single daily sessions (A); 3xHIIT: High-Intensity Interval Training performed in three shorter daily sessions (B). Both training groups (1xHIIT and 3xHIIT) performed the HIIT protocols 5 days per week over 8 weeks. The 1 × HIIT group performed single daily sessions of 3 min of warm-up, followed by six bouts of 1 min interspersed by 1 min of passive recovery (sessions of 15 min daily, in total). The 3xHIIT Group performed three shorter daily sessions composed of 1-min warm-up, followed by two bouts of 1 min interspersed by 1 min of passive recovery, with an interval of 4 h between sessions (sessions of 15 min daily, in total).
