Autonomic regulation after exercise evidenced by spectral analysis of heart rate variability in asthmatic children.

Background: Bronchial asthma is associated with abnormal autonomic nervous function in childhood. Exercise is one of the most common precipitating factors of acute asthmatic crises although the exact mechanism of autonomic regulation in asthmatic children after exercise is unclear.

Objective: The aim of this study was to investigate the features of autonomic regulation after exercise in asthmatic and control children.
