Intervention type: OTHER
Group type: ACTIVE_COMPARATOR
Intervention: Combined training
Description: The CT and CTc protocol (total length time \~60 min) were performed three times a week for 12 weeks, in nonconsecutive days, and were composed by 30-min walk at 70% of maximum heart rate or Borg Scale at 5-6 following resistance exercises (RE: 45-degree half squat, bench press, leg curl, rowing machine and unilateral leg extension) at 70% of one repetition maximum (1RM) with three sets of 8-12 repetitions and 1.5 min rest interval between sets and exercises. If the volunteer exceeded or did not reach the walk intensity, the volunteer was stimulated by to decrease or increase the walk speed, respectively. Regarding the resistance exercises, the load was adjusted in the 6th week with the 1RM test to ensure the 70% of 1RM between 8-12 repetitions.

Intervention: High intensity interval training with body weight
Description: The HIITBW and HIITBWc protocol (total length time \~28 min) were performed three times a week for 12 weeks, in nonconsecutive days, and were composed by ten sets of 60 s of high (vigorous) intensity exercises at 80-95% of HRmax or Borg Scale at 8-9 (i.e. 30s of stepping up and down on a step and 30s of squatting up and down as fast as possible) interspersed with a recovery of 60 s of light walk (\<60% of HRmax or Borg Scale at \<5). To ensure vigorous zone of all sets, if the volunteer exceeded or did not reach the vigorous zone the volunteer was stimulated by the fitness professionals to decrease or increase the number of steps and squats, respectively.
