This randomized controlled trial investigated post-exercise hypotension (PEH) in 47 physically inactive adults of African and South Asian descent with high-normal blood pressure or grade I hypertension. The study found that 46% of participants were systolic responders after aerobic exercise, showing significant improvements in cardiac output and aortic augmentation index compared to non-responders. In contrast, isometric exercise resulted in fewer responders.
Key findings
- 46% of participants were classified as systolic responders after aerobic exercise.
- Aerobic responders had a greater reduction in aortic augmentation index (-19.4% vs. -10.9%, p = 0.05).
- Cardiac output increased significantly in responders (+1.54 ± 1.89 vs. +0.58 ± 1.60 L/min, p = 0.009).
- No consistent physiological differences were observed following isometric exercise.
Why it matters
Understanding the variability in blood pressure responses to different types of exercise can inform personalized exercise prescriptions for individuals with hypertension, potentially improving management strategies and reducing cardiovascular risk.
