Aerobic exercise session
Resistance exercise session
Combined exercise session
The aerobic exercise session will be performed on a horizontal cycle ergometer. A warm-up will be performed (5 minutes), followed by 40 minutes with moderate intensity (60% HRreserve) and controlled by a heart rate monitor, as well as the subjective effort scale (Borg 6 to 20 points). Blood pressure, heart rate and the Borg scale will be assessed at the beginning of aerobic exercise and every 5 minutes until the end.
The resistance exercise session will be structured with knee extension, knee flexion, leg pressure and plantar flexion, in a station with guided weights, with 4x12 repetitions and 60% intensity of 1-RM; the cadence will be adjusted to 2:2 (concentric: eccentric) and controlled by a metronome. The rest between sets and exercises will be 90 seconds (total duration: 40 minutes). Blood pressure, heart rate and Borg scale will be recorded at the beginning and at the end of the 4th series of each exercise.
The combined exercise session will be structured with 20 minutes of resistance exercise + 20 minutes of aerobic exercise, as already described, except that the resistance exercises will have 2 sets of each exercise. As with other sessions, blood pressure, heart rate and the Borg scale will be assessed at the beginning and end of the second series of resistance exercise, as well as at the beginning and every 5 minutes of aerobic exercise up to 15 minutes after end of exercises.
