Abstract

Introduction: The variability of heart rate is understood as the time variation between the intervals of R waves of electrocardiogram and it allows to represent the functioning of the organism in certain stimuli. Based on this, it is relevant to understand the strength training effects on the cardiovascular system parameters, since controversies are generated around cardiac physiology, even more so, in people with hypertensive pathology. Objective: To identify the effects of strength training on heart rate variability in hypertensive patients. Methods: A bibliographic review of the main Ebsco Host, Web of Science, Health Medical Collection, Scopus and Medline databases was carried out to identify the experimental articles in the last 10 years. Eleven articles were retrieved, from the combination of the keywords heart rate variability, strength training and hypertension. Results: The retrieved investigations refer to the changes in the frequency and temporal variables of heart rate variability, through strength training. Mainly with the treble effects, it increases LF and decreases HF; while, with chronic effects, LF values and LF/HF ratio decrease. Conclusions: The data from this study report changes in HRV parameters with force stimuli in people with hypertension.
