Group Intervention Description Hydration protocol water The control protocol will consist of an initial 10 minutes of rest, followed by 90 minutes of aerobic activity and 60 minutes of the final recovery. In this protocol, volunteers will be hydrated with mineral water from the 15th minute of exercise until the end of recovery Hydration protocol aerobic activity The control protocol will consist of an initial 10 minutes of rest, followed by 90 minutes of aerobic activity and 60 minutes of the final recovery. In this protocol, volunteers will be hydrated with mineral water from the 15th minute of exercise until the end of recovery Control protocol aerobic activity The control protocol will consist of an initial 10 minutes of rest, followed by 90 minutes of aerobic activity and 60 minutes of the final recovery. Hydration will not be allowed throughout the protocol
- Primary Outcome Measures
Name Time Method Autonomic Modulation - SD2 index up to 3 weeks The data for this evaluation will be collected using a heart rate monitor that registers the heart rate beat by beat and provides information regarding the RR intervals. The SD2 index corresponds to the dispersion of points along the line of identity of the ellipse obtained from the Poincaré plot. Expressed in milliseconds.
Blood Pressure up to 3 weeks Will occur indirectly, using a stethoscope and an aneroid sphygmomanometer in the left arm. The indicated values will be registered in an individual form. To avoid errors in the determination of blood pressures in volunteers, a single evaluator will measure these variables throughout the experimental procedure. Data will be collected at the end of the 10 minutes of initial rest and at minutes 30, 60 and 90 during exercise on the treadmill, as well as will be collected at minutes 1, 5, 10, 20, 30, 40, 50 and 60 of recovery.
Heart Rate up to 3 weeks The heart rate will be captured beat by beat using the Polar RS800CX frequency meter, equipment previously validated to capture this parameter. Data will be collected at the end of the 10 minutes of initial rest and at minutes 30, 60 and 90 during exercise on the treadmill, as well as will be collected at minutes 1, 5, 10, 20, 30, 40, 50 and 60 of recovery.
Autonomic Modulation - SD1 index up to 3 weeks the data for this evaluation will be collected using a heart rate monitor that registers the heart rate beat by beat and provides information regarding the RR intervals. The SD1 index corresponds to the dispersion of points perpendicular to the line of identity of the ellipse obtained from the Poincaré plot. Expressed in milliseconds.
