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.
