Effects of Exercise on Heart Rate Variability: Inferences from Meta-Analysis

Chronic exercise training produces a resting bradycardia that is thought to be due partly to enhanced vagal modulation.The aim of the present study was to determine the effects of exercise training on heart rate and measures of heart rate variability associated with vagal cardiac modulation and to quantify the relationship between changes in these measures.A random effects model of effect size (d) for change in high frequency (HF) power and RR...
