Objetive: Exercise produces physiological responses that generate a blood pressure reduction below the values measured before exercising; such response is evident after exercising and is called post exercise hypotension. The aim of this study was to compare the differences in the magnitude and duration of post-exercise hypotension made at 2 intensities (50% and 70% of HR reserve) in normotensive and physically active subjects. Method: Subjects were a total of 10 healthy and physically active men, aged 49, 22 ± 7. 03 years. Procedure: randomly performed 3 sessions, 2 at exercise treadmill at different intensities (50% heart rate reserve and 70% heart rate reserve) and a control session. Session lasted 1: 35 min, which was divided in 5 minutes of rest, 30 min from the corresponding session and 60 min measuring of blood pressure after the session. Results: Significant statistical differences were encountered in the systolic blood pressure, realizing decreases in the systolic blood pressure after exercise at 2 different intensities, however the reduction was more durable to exercise at 70% of the heart rate reserve (60 minutes) that 50% of the heart rate reserve (30 minutes). Conclusion: Validated the existence of the hypotensive effect in systolic blood pressure after 2 sessions of aerobic exercise on treadmill; however the best results are obtained when exercising at an intensity of 70% heart rate reserve.
