结局指标
主要结局
Blood Pressure
时间窗: 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
时间窗: 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
时间窗: 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.
Autonomic Modulation - SD2 index
时间窗: 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.
