This study evaluated the effects of acute arginine supplementation (ARG) on post-exercise hypotension (HPE). For this, 12 physically active young men participated in this randomized, double-blind crossover clinical trial. All were submitted to two experimental conditions (ARG or placebo - PLA). 45 minutes after supplementation, all participants performed 30 minutes of moderate-intensity aerobic exercise (70-75% of reserve heart rate). Heart rate and systolic and diastolic blood pressures were measured before, 30 and 60 minutes after exercise. In comparison with pre-exercise means, there was a lower systolic blood pressure until to 60 min post-exercise (117.3±6.5 vs. 109.6±7.2 mmHg, p=0.001), lower mean arterial blood pressure (89.1±7.0 vs. 83.8±8.2 mmHg, p=0.024), increased heart rate (67.1±11.9 vs. 84.8±6.8 bpm, p=0.001) and the double product (7988±1372 vs. 9734±990 mmHg.bpm, p=0.006) until 30 min post-exercise. However, there was no significant difference between experimental conditions. Using the methods applied, our results demonstrated that there was no effect of acute ARG supplementation on aerobic HPE in physically active young men.
