Stretching, isometrics, and aerobic exercise for decreasing blood pressure post-exercise: a randomized crossover study
Randomized crossover in nine young normotensive adults compared 30-minute sessions of static stretching, isometrics, aerobic cycling at 75% VO2peak, and rest: only stretching and aerobic cycling produced statistically significant ~10 mmHg post-exercise systolic blood pressure reductions versus control across the 60-minute recovery window.
Design
- Crossover RCT: 9 healthy adults (5 M / 4 F; ~21 y)
- Conditions (30 min): static stretching (30 s holds), isometric exercise, cycle ergometry 75% VO2peak, rest control
- BP / HR: measured pre and 60 min post
BP results (abstract)
- Post-exercise SBP: stretching and aerobic each ~−10 mmHg vs control trajectory (p < 0.05)
- Isometrics and control: no significant post-exercise SBP dip in abstract framing
Evidence hygiene
Young normotensive sample—acute post-exercise hypotension physiology rather than chronic hypertension treatment trials.

Outcomes
- Systolic Blood Pressure-10mmHg (Millimetres of Mercury)
- Isometric exercise did not reproduce statistically significant post-exercise systolic blood pressure reduction versus control in this crossover (abstract).
