AER+R group
In each session, the AER+R group performed alternative blocks of aerobic and resistance training, and the sum of those blocks resulted in 50% aerobic training plus 50% resistance training. Participants performed a 5-min warm-up before the beginning of the session. The aerobic training program followed a HIIT protocol: four bouts of 3 min at 85–95% HRmax (obtained in the maximal endurance test) interspersed and 5 min of active recovery at 75–85% HRmax. Resistance training consisted of a combination of isometric training and 12–15 repetitions at 50%–70% of the maximum isometric strengths obtained in the DynaSystem Research Functional Dynamometer, distributing all of the major muscle groups between the two sessions of the week.Like the BAS group, all of the participants answered the RPE scale when the session was concluded. This information was used to increase or decrease the intensity of the training individually.
