Heart rate and perceived exertion: HR was measured using a heart rate monitor brand Polar RS800CX model (Polar ElectroOy, Kempele, Finland). The measurements were made after 10 minutes at rest and every 5 minutes Durantes exercises. In the same times that HR was measured, the Subjective Perception Scale of Borg effort (Noble and Borg et al, 1983), with scale 6-20 points, was presented to the participants and asked who said they had their feelings of stress.
