Key result
Morning aerobic exercise produced a significantly greater net reduction in systolic blood pressure (-7 ±3 mmHg) compared to evening exercise (-3 ±4 mmHg) when controlling for circadian variations.
Why the study?
Does aerobic exercise performed in the morning versus the evening improve post-exercise hypotension in pre-hypertensive men?
RCT (n=16)
Simple randomization
No

Absolute Event Rate: -7% vs -3%
p-value: p=<0.05
Morning aerobic exercise produces a greater systolic post-exercise hypotensive effect than evening exercise in pre-hypertensive men when accounting for circadian blood pressure variations.
No takes yet. Share an insight, caveat, or question.
May warrant morning aerobic exercise to enhance post-exercise BP reduction in pre-hypertension; extends chronobiology evidence for exercise prescriptions.
Brito et al. (2015) conducted an RCT in Pre-hypertension (n=16). Morning aerobic exercise (cycling) vs. Evening aerobic exercise (cycling) was evaluated on Net effect of exercise on systolic blood pressure (mmHg) (p=<0.05). Morning aerobic exercise produced a significantly greater net reduction in systolic blood pressure (-7 ±3 mmHg) compared to evening exercise (-3 ±4 mmHg) when controlling for circadian variations.
