Key result
Post-exercise cooling with a fan equally accelerated heart rate recovery at 300 seconds (39 vs. 36 bpm) and increased post-exercise heart rate variability in both hypertensive and normotensive men.
Why the study?
Postexercise cooling accelerates heart rate recovery in healthy individuals, but its effects in populations with cardiac autonomic dysfunction, such as hypertensive subjects, were unclear.
Does postexercise cooling improve heart rate recovery in hypertensive and normotensive men?
RCT (n=48)
Randomly allocated
No
Does postexercise cooling improve heart rate recovery in hypertensive and normotensive men?
Absolute Event Rate: 39% vs 36%
p-value: p=≤0.05
Postexercise cooling accelerates heart rate recovery and increases heart rate variability similarly in both hypertensive and normotensive men.
No takes yet. Share an insight, caveat, or question.
Supports post-exercise fan cooling to enhance autonomic recovery in men; extends benefits equally to hypertensive patients.
Peçanha et al. (2019) conducted an RCT in Hypertension (n=48). Post-exercise cooling with a fan vs. No cooling (control) was evaluated on Heart rate recovery at 300 seconds (HRR300s) (p=≤0.05). Post-exercise cooling with a fan equally accelerated heart rate recovery at 300 seconds (39 vs. 36 bpm) and increased post-exercise heart rate variability in both hypertensive and normotensive men.
