This controlled clinical trial investigated the effects of a 16-week aerobic exercise program on heart rate variability (HRV) and C-reactive protein (CRP) in middle-aged adults with normal weight and overweight/obesity. The study found that the overweight/obesity group had a significant decrease in resting heart rate (Β = -4.35, p = 0.049) but an increase in CRP (Β = 1.22, p = 0.045) compared to the normal weight group.
Key findings
- Overweight/obesity participants showed a significant decrease in resting heart rate (Β = -4.35, p = 0.049).
- The same group experienced a significant increase in C-reactive protein (Β = 1.22, p = 0.045).
- HRV parameters associated with parasympathetic activity fluctuated more in the normal weight group during exercise.
Why it matters
Understanding the differential responses to aerobic exercise based on body weight can help clinicians tailor exercise recommendations. Monitoring HRV and inflammation may enhance safety and effectiveness in exercise regimens for middle-aged adults.
