Implication
Clinically relevant BP reductions follow acute exercise, especially in hypertensives; leaves open optimal protocols and sustained effects under free-living conditions.
Structured PICO
Does a single bout of large-muscle dynamic exercise reduce arterial blood pressure in normotensive and hypertensive subjects?
P
Population
Normotensive and hypertensive humans, and spontaneously hypertensive rats
I
Intervention
Single bout of large-muscle dynamic exercise (walking, running, leg cycling, and swimming) at submaximal intensities greater than 40% of peak aerobic capacity for 20 to 60 minutes
O
Outcome
Reduction in arterial blood pressure (postexercise hypotension)surrogate
A single bout of dynamic exercise induces clinically significant postexercise hypotension, particularly in hypertensive individuals, though its duration under free-living conditions requires further study.
Limitations
- Whether PEH is sustained for a prolonged period of time under free-living conditions remains controversial
- More investigation is required to determine if the duration is sufficient under real-life conditions to contribute to the reduction in blood pressure observed with chronic exercise conditioning
