* Significant difference between first and second half at MIIT and GXT (p ≤ 0.05).** Significant difference between first and second half at MIIT and GXT (p ≤ 0.01).‡ Significant difference between first half and second half during MIIT (p ≤ 0.01).VO = oxygen consumption; HR = heart rate; BLa = blood lactate concentration; RPE = average of rate of perceived exertion; RPE = rate of perceived exertion measured at the end of first and second half of MIIT; GXT = graded exercise test; MIIT = moderate-intensity interval training session; NA: not applicable as it was not measured.
