Key result
Exercise training improved cardiac autonomic balance in patients with chronic heart failure, with 5 of 6 RCTs showing increased high frequency and decreased LF/HF ratio for heart rate variability.

Systematic Review (n=280)
Does exercise training improve heart rate recovery and heart rate variability in patients with chronic heart failure?
Exercise training has positive effects on cardiac autonomic balance, improving heart rate recovery and heart rate variability in patients with chronic heart failure.
Hsu et al. (2015) conducted a systematic review in Chronic Heart Failure (n=280). Exercise training (aerobic or resistance) was evaluated on Heart rate recovery (HRR) and heart rate variability (HRV). Exercise training improved cardiac autonomic balance in patients with chronic heart failure, with 5 of 6 RCTs showing increased high frequency and decreased LF/HF ratio for heart rate variability.
