The claim is that physical activity significantly impacts human blood pressure. This is a specific, empirical, and well-studied physiological relationship. Multiple retrieved papers, including meta-analyses and randomized trials, demonstrate that various forms of exercise (isometric, aerobic, and resistance training) produce significant reductions in resting systolic and diastolic blood pressure, while disruptions in physical activity (such as during lockdowns) are associated with blood pressure increases. Although one study in a low-socioeconomic older adult cohort reported null findings over a long-term follow-up, the overwhelming weight of high-quality evidence supports the claim.
