Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention consisted of an aerobic workout, in which the volunteers had their heart rate monitored for heart rate monitors, this training was supervised by two previously trained professionals, they recorded the volunteers' heart rate during training sessions and gave verbal feedback to them to keep the frequency target rate in the range previously established. The training had a frequency of three times weekly, the training sessions had a gradual increase in the first 30 minutes duration and the final 55 minutes long, also the training protocol was 12 weeks.
