简要总结
This study aims to evaluate post-exercise recovery in healthy young men submitted to a prolonged exercise protocol of submaximal intensity with or without water intake, from the integrated analysis of autonomic (heart rate variability indices), cardiovascular outcomes (systolic blood pressure, diastolic blood pressure and heart rate) and respiratory (oxygen saturation and respiratory frequency). In addition, it will also be evaluated whether the proposed model is able to estimate the number of individuals undergoing hydration that have better recovery.

结局指标
主要结局
Autonomic Modulation - SD1 index
时间窗: Acute evaluation during interventions
he 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.
Blood Pressure
时间窗: Acute evaluation during interventions
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, 3, 5, 7, 10, 20, 30, 40, 50 and 60 of recovery.
Peripheral oxygen saturation
时间窗: Acute evaluation during interventions
Will be checked using a pulse oximeter. A pulse oximeter is a device that provides blood saturation readings, evaluating the absorption behavior of oxyhemoglobin and deoxyhemoglobin in relation to the lengths of red and infrared light. 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, 3, 5, 7, 10, 20, 30, 40, 50 and 60 of recovery.
Autonomic Modulation - HF index
时间窗: Acute evaluation during interventions
he 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 HF index is the high-frequency component of the oscillatory components of heart rate variability, and ranges from 0.15 to 0.4 Hz.
Autonomic Modulation - SDNN index
时间窗: Acute evaluation during interventions
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 SDNN index corresponds to the standard deviation of all normal RR intervals recorded in a time interval, expressed in milliseconds.
Heart Rate
时间窗: Acute evaluation during interventions
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, 3, 5, 7, 10, 20, 30, 40, 50 and 60 of recovery.
Autonomic Modulation - rMSSD index
时间窗: Acute evaluation during interventions
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 rMSSD index corresponds to the root-mean square of differences between adjacent normal RR intervals in a time interval, expressed in milliseconds.
Autonomic Modulation - LF index
时间窗: Acute evaluation during interventions
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 LF index is the low-frequency component of the oscillatory components of heart rate variability, and ranges from 0.04 to 0.15 Hz.
Respiratory Rate
时间窗: Acute evaluation during interventions
The measurements will be performed by counting the breaths for one minute without the volunteer being aware of the process, so that the usual breathing characteristics are not modified. Data will be collected at the end of the 10 minutes of initial rest as well as will be collected at minutes 1, 3, 5, 7, 10, 20, 30, 40, 50 and 60 of recovery.
Autonomic Modulation - SD2 index
时间窗: Acute evaluation during interventions
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.
