Abstract

Little is known regarding the influence of asthma and exercise, and their interaction, on heart rate variability (HRV) in adolescents.Thirty-one adolescents with asthma (13.7±0.9 years; 21.9±3.9 kg·m−2; 19 boys, 12 girls) and thirty-three healthy adolescents (13.8±0.9 years; 20.3±3.2 kg·m−2; 16 boys...
