A 1-hour increase in vigorous physical activity was associated with a 1.69 mmHg reduction in systolic home blood pressure and a 1.09 mmHg reduction in diastolic home blood pressure.

Does objectively measured physical activity and step count reduce home blood pressure in community-dwelling adults?
Objectively measured higher step counts and longer time spent in vigorous physical activity are associated with modest reductions in home blood pressure, particularly among men and adults under 60 years.
Effect estimate: β -1.69 mmHg (95% CI -2.24 to -1.13)

Few studies have examined the association of objectively measured habitual physical activity (PA) and sedentary behavior with out-of-office blood pressure (BP). We investigated the associations of objectively measured PA intensity time, sedentary time, and step count with at-home BP. Using accelerometer-recorded PA indices and self-measured BP in 368 participants (mean age, 53.8 years; 58.7% women), we analyzed 115,575 records of each parameter between May 2019 and April 2024. PA intensities were categorized as light (2.0-2.9 metabolic equivalents METs); moderate (3.0-5.9 METs); vigorous (≥6.0 METs), or sedentary (<2.0 METs): the median interquartile ranges for these variables was 188 146-232, 83 59-114, 1 0-2, 501 428-579 minutes, respectively, and for step count, was 6040 4164-8457. Means standard deviations for systolic and diastolic BP were 116.4 14.2 and 75.2 9.3 mmHg, respectively. A mixed-effect model adjusted for possible confounders showed that 1-h longer in vigorous PA was associated with lower systolic and diastolic BP (-1.69 and -1.09 mmHg, respectively). A 1000-step increase in step count was associated with lower systolic and diastolic BP (-0.05 and -0.02 mmHg, respectively). Associations were more pronounced among men and participants aged <60 years. Sedentary time was positively associated with BP in men and participants aged <60 years, but inversely associated with BP in women and participants aged ≥60 years. Our findings suggest that more PA and less sedentary behavior were associated with BP reduction, particularly among men and participants aged <60 years. However, the clinical relevance of this effect remains uncertain because of its modest magnitude.
Kinuta et al. (Thu,) conducted a cohort in Community-dwelling individuals (n=368). Vigorous physical activity vs. Lower levels of vigorous physical activity was evaluated on Systolic home blood pressure (β -1.69 mmHg, 95% CI -2.24 to -1.13, p=<0.001). A 1-hour increase in vigorous physical activity was associated with a 1.69 mmHg reduction in systolic home blood pressure and a 1.09 mmHg reduction in diastolic home blood pressure.
