Since exercise-induced asthma (EIA) is common in asthmatic children, it may get in the way for physical exercise. Exercise gives pleasure and is neccessary for growth in children with asthma, so prevention of EIA becomes important. In this study, short time vigorous exerise did not induce EIA. Disodium cromoglycate (DSCG) solution prevented EIA for 11 patients out of 14 one hour after inhalation, and in others 4 to 8 hours after inhalation.
　Procaterol solution had a greater effect than DSCG at any time point. Our exercise program was carried out with presence of their parents. It was thought to be suitable for young children with asthma because it was done in accordance with changes in heart rate (less than 160 / min) and peak flow rate.
　Under high pressure conditions, lung functions improved in asthmatics.
