Implication

Single bouts of exercise may confer acute cardioprotection via autonomic shifts; extends RCT evidence on transient HRV benefits in young men.

Structured PICO

Does a single bout of exercise improve resting heart rate variability in healthy young men?

P
Population
11 healthy male volunteers ages 18-35 years
I
Intervention
A single 60-minute bout of cycling exercise at approximately 65% of peak oxygen uptake
C
Comparator
Nonexercise condition
O
Outcome
Resting heart rate variability (HRV) measures including high-frequency HRV, low-frequency HRV, LF/HF ratio, and pNN50 obtained during 5 minutes of paced breathing before and 1, 3, 6, and 22 hours after interventionsurrogate

A single bout of submaximal exercise transiently shifts cardiac autonomic function toward increased parasympathetic and decreased sympathetic activity, suggesting acute cardioprotective effects.
