Interventions

All study participants underwent the study protocol consisting of four stages, as follows: Step I: consisted of determining the load of exercise to be used in subsequent steps treadmill. The belt load
Step II (Control Protocol - PC): the individuals were submitted to 90 minutes of exercise (equivalent intensity 60 % of VO2peak) followed by 60 minutes of recovery without administration of hydration
Step III (Intervention Protocol 1 - PH1): subjects were submitted to 90 minutes of exercise (equivalent to 60 % of VO2 peak intensity) followed by 60 minutes of recovery, but with water management. Th
Stage IV (Intervention Protocol 2 - PH2): subjects underwent 90 minutes of exercise (intensity equivalent to 60 % of VO2peak) followed by 60 minutes of recovery, but with administration of isotonic dr
