Key result
Relative to moderately paced walking, 6 months of regular swimming significantly increased supine systolic blood pressure by 4.4 mmHg (95% CI 1.2-7.5; P=0.008) in sedentary, normotensive older women.
Why the study?
Does a supervised 6-month swimming programme improve blood pressure compared to walking in previously sedentary, normotensive older women?
RCT (n=116)
Randomized
Does a supervised 6-month swimming programme improve blood pressure compared to walking in previously sedentary, normotensive older women?
Mean Difference: 4.4 (95% CI 1.2–7.5)
p-value: p=0.008
Contrary to common recommendations, regular swimming significantly elevates blood pressure relative to walking in previously sedentary, normotensive older women.
No takes yet. Share an insight, caveat, or question.
Swimming raises supine SBP versus walking in sedentary normotensive older women; challenges exercise recommendations favoring swimming for BP control.
Cox et al. (2006) conducted an RCT in Sedentary, normotensive (n=116). Swimming vs. Walking was evaluated on Supine systolic blood pressure (MD 4.4 mmHg, 95% CI 1.2, 7.5, p=0.008). Relative to moderately paced walking, 6 months of regular swimming significantly increased supine systolic blood pressure by 4.4 mmHg (95% CI 1.2-7.5; P=0.008) in sedentary, normotensive older women.
