Captopril does not Potentiate Post-Exercise Hypotension: A Randomized Crossover Study

To evaluate whether captopril (3×50 mg/day) potentiates post-resistance exercise hypotension (PREH) in hypertensives (HT), 12 HT men received captopril and placebo for 4 weeks each in a double-blinded, randomized-crossover design. On each therapy, subjects underwent 2 sessions: Control (C – rest) and Resistance Exercise (RE – 7 exercises, 3 sets to moderate fatigue, 50% of 1 RM –repetition maximum). Measurements were taken before and after 30–60 min (Post1) and 7 h (Post2), and ambulatory blood pressure (BP) was monitored for 24 h. There were no differences in PREH characteristics and mechanisms between the placebo and captopril periods. At Post1, systolic/diastolic BP decreased significantly and similarly after RE with both therapies (Placebo=−13±2/−9±1 mmHg vs. Captopril=−12±2/−10±1 mmHg, P
