HEMODYNAMIC RESPONSES OF A STRENGTH TRAINING SESSION WITH TWO DIFFERENT INTENSITIES OF BLOOD FLOW RESTRICTION IN NORMOTENSIVE ELDERLY WOMEN

Objectives: To evaluate the blood pressure response after two types of Blood Flow Restriction intensity in healthy women over 60 years of age. Material and Methods: Thirty healthy elderly women aged over 60 years were were randomly assigned to three groups (control placebo: 20% one maximus repetitions + 0% BFR, RF60: 20% one maximus repetitions + 60% BFR and, RF80: 20% one maximus repetitions + 80% BFR) performed the exercises of Leg Press, Elbow Extension, Knee Extension and Elbow Flexion, did the training protocol composed of 3 sets of 15 repetitions, with a 60-second interval between each series. The data were analyzed by Prism 5 with significance level of p<0.05 was adopted. Results: the RF60 group induced a significant decrease in the behavior of Systolic Arterial Pressure (SAP) and Heart Rate (HR) in the period of 24h and 48h after the exercise session, promoting hypotensive responses and bradycardic response in 48h when compared to the initial evaluation baseline. The RF80 group promote changes in SAP in 24 and 48h when compared to baseline but not in Diastolic Arterial Pressure (DAP) and HR. Conclusion: we conclude that acutely 60% and 80% of BFR training was effective in to promote decrease of the blood pressure in the elderly in up to 48 hours after the session.
