Abstract

Background: An acute session of resistance exercise changes cardiovascular parameters according to the type of prescription. The objective this study to evaluate the heart rate, systolic and diastolic blood pressure and myocardial oxygen consumption behaviors during execution of resistance exercise applied in acute and isolated way, with different intensities and body segments. Methods: 52 healthy and active young performed the experimental protocol with five stages. In the first stage, it was carried out the one-repetition maximum test (1RM) for knee extension (LL) and elbow flexion (UL) and, in the following phases, four resistance exercise protocols were applied, on different days with random order execution: endurance protocol (2 series, 20 reps and 40% of 1RM) and strength protocol (2 series, 8 reps and 80% of 1RM) for upper and lower limbs. Heart rate (HR) was monitored by Polar S810i heart rate monitor, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by auscultation in the left arm, and MVO2 was calculated from SBP and HR. All these measurements were measured immediately after the execution of the first (M1) and second (M2) series. Finding: There were significant increases in M1 and M2 in comparison to their respective rest in HR (p <0.001), SBP (p <0.05) and MVO2 (p <0.001) in all protocols applied. For PAD there were significant decreases in M1 of endurance (p = 0.028) and force lower limbs (p = 0.022) protocols compared to the resting values. There are no significant changes among the proposed protocols. Conclusion: Strength and endurance protocols, run with upper and lower limbs, applied in acute and isolated way, were able to promote changes in cardiovascular variables in relation to their respective resting value. However, lower limbs endurance protocol stands out in their differences among them, due to the longer execution period and larger muscle group.
