Hypotensive effect in resistance training: influence of muscle mass

Abstract

Introduction: Muscle mass (MM) requested during resistance exercise (RE) influences on cardiovascular responses. Objective: To compare the effect of MM on cardiovascular responses during and after the ER. Methods: Eleven normotensive subjects (22.2 ± 2.8 years; 171.2 ± 9.4 cm; 68.0 ± 12.6 kg) were submitted, on different days, to the follow exercises: bench press (SR) and albacore (VOA). Measurements of blood pressure (BP), heart rate (HR) and double product (DP) were made at rest, immediately after exercising, and during 60 minutes post-exercise. Results: Both exercises caused increased BP, HR and DP compared to rest (p <0.05). In the post-exercise period, statistical reduction in systolic BP was observed after 40 minutes of exercise VOA, and in the SR it was observed on the 40th, 50th and 60th minutes (p <0.05). The diastolic BP did not change. Conclusion: MM did not have an influence in BP, HR and DP, however it did influenced the duration of the hypotensive effect.
