Universidade Estadual Paulista Júlio de Mesquita Filho31 enrolled

Overview

The objective of this study is to analyze the influence of hydration and functional aerobic capacity in young and healthy individuals on non-linear heart rate dynamics as a technique that favor faster and more efficient recovery cardiac autonomic modulation.

Outcomes

Primary Outcomes

Blood Pressure

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.

Time frame: up to 3 weeks

Heart Rate

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.

Time frame: up to 3 weeks

Autonomic Modulation - SD1 index

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.

Time frame: up to 3 weeks

Autonomic Modulation - SD2 index

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.

Time frame: up to 3 weeks
