Decrease of exercise-induced asthma after physical training.
Exercise-induced asthma (EIA) is a multifactorial disease induced by cooling and drying of the airways. Mediator release or vagal stimulation, or both, may transmit the reaction to bronchial muscles. Premedication with beta 2-aerosol before exercise has the best preventive effect, although disodium cromoglycate (DSCG) or atropine prevent EIA in about 50% of the patients. EIA is provoked when the anaerobic threshold is passed. Training with high load interval exercise after premedication increased the anaerobic threshold in three groups of children, and a significant decrease in EIA was recorded, while a non-training control group showed no changes.
