Abstract

Background: Although Aerobic Exercise (AE) has been recognized for lowering Blood Pressure (BP), little is known about the alterations in aortic BP after exercise (1,2). PURPOSE: To investigate the acute pulse wave reflection responses induced by AE with different volumes in normotensive and hypertensive men.

Methods: We included 12 normotensives [aged: 38.3 ± 10.1 years, body mass index (BMI): 25.9 ± 3.6 kg/m2, maximal oxygen uptake (VO2max): 31.4 ± 6.9 mL·kg−1·min−1, systolic/diastolic BP (SBP/DBP): 121 ± 6/74 ± 4 mmHg] and 7 hypertensive men [aged: 39.1 ± 6.0 years, BMI: 29.4 ± 3.1 kg/m2, VO2max: 26.1±1.8 mL·kg−1·min−1, SBP/DBP: 140 ± 8/88 ± 7 mmHg]. The participants were submitted to a maximal cardiopulmonary exercise test, a non-exercise control session (CTL), and two bouts of continuous cycling at 50% VO2 reserve (150 vs. 300 kcal) in a randomized, counter-balanced order. Aortic systolic pressure, aortic pulse pressure, augmentation pressure, and augmentation index (AIx) were determined 10 min before and 70 min after the CTL and the two exercise bouts in a supine position by applanation tonometry (SphygmoCor v7).

Results: Central pressures and AIx were different between normotensive and hypertensive men after the two AE bouts as shown in table 1.

Conclusion: Although both AE were able to reduce pulse wave reflection in hypertensive men, only the major volume has attenuated the increase in central aortic BP observed in the control session.
