Encouraging direction, but not yet definitive.
This randomised crossover trial characterises post-exercise blood pressure responders versus non-responders to aerobic and isometric exercise in a hypertensive population of African and South Asian descent. Aerobic exercise responders (46% of participants) show distinct physiological signatures including greater reductions in aortic augmentation index, favourable cardiac output changes, and improved autonomic recovery, with cardiac output change associated with blood pressure reduction magnitude. However, the study uses surrogate endpoints and lacks long-term clinical outcome validation.
Randomised controlled crossover trial. Physically inactive adults of African and South Asian descent, aged 18–65 years, with high-normal blood pressure or grade I hypertension. Setting: Suriname. No baseline differences in demographic or clinical characteristics were observed between later-classified responders and non-responders.. Intervention: Aerobic exercise: 30 minutes at 40–60% heart rate reserve; Isometric handgrip exercise. Compared with: Non-exercise control condition. n = 47. Suriname.
46% of participants were systolic responders following aerobic exercise versus 28% after isometric exercise Aerobic responders demonstrated greater reductions in aortic augmentation index (−19.4% vs. −10.9%, p = 0.05) Aerobic responders showed larger increases in stroke volume (+8.1 vs. −5.3 mL, p = 0.05)

These findings suggest that post-exercise blood pressure response is highly variable and phenotype-dependent, driven by distinct cardiac and autonomic adaptations rather than baseline clinical characteristics. Clinicians should consider that aerobic exercise may be more effective in inducing hypotensive responses than isometric exercise in this population, but individual stratification remains necessary; the work supports tailored exercise prescription but does not yet establish how to predict responders prospectively.
A rigorous randomised crossover trial in a specific population demonstrating a mechanistic characterisation of responders to aerobic exercise, but limited by modest sample size, surrogate endpoints (arterial stiffness, autonomic parameters), and lack of long-term clinical outcome data.

Objective. To investigate interindividual variability in post-exercise hypotension (PEH) and to characterise cardiovascular and autonomic differences between responders and non-responders following aerobic and isometric exercise in adults of African and South Asian descent with elevated blood pressure (BP).Methods. Physically inactive adults of African and South Asian descent living in Suriname (18-65 years) with high-normal BP or grade I hypertension participated in a randomised controlled crossover trial. In this randomised cross-over trial, 47 adults (50.1 ± 10.8 years; 38% male) with high-normal blood pressure or grade I hypertension completed three conditions: aerobic exercise (30 min at 40-60% heart rate reserve), isometric handgrip exercise, and a non-exercise control. Ambulatory BP was assessed over 24 h. PEH was defined as the net effect: (post-exercise - pre-exercise) - (post-control - pre-control). Participants were classified as responders if daytime BP decreased ≥5 mmHg. Arterial stiffness, cardiac, and autonomic parameters were assessed.Results. Following aerobic exercise, 46% of participants were classified as systolic responders compared with 28% after isometric exercise. No baseline differences were observed in demographic or clinical characteristics between responders and non-responders, suggesting that PEH variability may reflect underlying physiological rather than clinical differences. Aerobic responders demonstrated greater reductions in aortic augmentation index (-19.4% vs. -10.9%, p = 0.05), larger increases in stroke volume (+8.1 vs. -5.3 mL, p = 0.05) and cardiac output (+1.54 ± 1.89 vs. +0.58 ± 1.60 L/min, p = 0.009), and more favourable autonomic recovery. Among all variables, only the change in cardiac output was associated with PEH magnitude (r = -0.46, p = 0.006). No consistent physiological differences were observed following isometric exercise.Conclusion. PEH following aerobic exercise is characterised by a distinct responder phenotype associated with greater reductions in aortic augmentation index and favourable cardiac adaptations. These findings highlight substantial interindividual variability in BP responses and support the need for individualised exercise strategies in hypertension management.
