Influência do Número de Séries na Hipotensão Pós-Exercício Resistido em Indivíduos Hipertensos Sedentários

Abstract

Objective: To measure the effect of two resistance training sessions (RT), of equal intensity, but different volumes on the post-exercise hypotension in hypertensive sedentary individuals. Material and Methods: Twelve people (four men and eight women) (54±6.74 years) hypertensive controlled and sedentary, after two weeks of neuromuscular adaptation in Leg Press 45o (LP45), Seated Rows (SR), Leg Extension (LE) and Horizontal Bench Press (BP) and determination of the maximum muscle strength, underwent two random RT sessions. The sessions consisted in performing one or three sets of 10 repetitions with 50% of 1-RM, randomly in the LP45, SR, LE and BP. Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), double product (DP) were measured in the rest, immediately after the last exercise (IALE), 10, 20, 30 and 40 minutes after the end of the RT sessions. The perceived exertion was measured IALE. Results: The results showed that one and three sessions of RT induced similar increases in cardiovascular parameters assessed (SBP, DBP, HR and DP) IALE, however, the session with three sets of exercises induced higher perceived exertion. The post-monitoring exercise up to 40 minutes exhibited significant decrease in SBP, DBP and DP in both RT sessions, which is more consistent and longer duration in session with three sets of exercises. Conclusion: We conclude that RT session with three sets induces a higher post-exercise hypotension effect than a single series session, in sedentary hypertensive individuals.
