Analysis of Heart Rate Variability After a Physical Exercise Session

Status Recruiting

Clinical Trial Summary

Systemic arterial hypertension (SAH) is a multifactorial clinical condition, characterized by sustained elevation of blood pressure levels, contributing to 50% of deaths from cardiovascular disease. The Autonomic Nervous System (ANS) plays a fundamental role in the regulation of Blood Pressure (BP) and is closely associated with Heart Rate (HR). HR changes are called Heart Rate Variability (HRV). In individuals with SAH, HRV indices are reduced compared to normotensive individuals, showing changes in autonomic modulation, thus increasing the risk for cardiovascular events. The objective of this study will be to analyze the Heart Rate Variability in individuals with controlled SAH after a session of aerobic (EA) or resistance (RE) physical exercise.

Clinical Trial Description

Controlled hypertensive individuals aged between 30 and 59 years will be selected, for convenience, who use the services of the Instituto de Cardiologia do Rio Grande do Sul. Volunteers will be randomly assigned to an EA session (40 minutes on cycle ergometer, 60% of heart rate reserve) or RE (2 exercises for lower limbs and 2 for upper limbs with 4 sets of 12 repetitions at 60% 1-RM) or control group without exercise. HRV data will be collected by ECG (Wincardio USB - Version 11.1.0.0, MICROMED Biotecnologia Ltda, Brasília - DF - Brazil) during 10 minutes before the exercise session, 10 minutes after the exercise session, 1h and 2h post-session . It is expected to estimate results that may demonstrate clarifications about the impact of a physical exercise session on HRV in controlled hypertensive individuals. ;
