60 children with bronchial asthma were investigated of the age of 11-15. Children, who were investigated, were divided into 2 groups: the first group consisted of 30 children, who did exercises in the sport hall; the second group consisted of 30 children, who did exercises in the water. Physical therapy for both groups was provided for 30 minutes 6 days a week 1 time per day. Physical therapy included active gymnastic exercises using various physical therapy tools. It was provided two lung ventilation tests with spirometer “Spiromed 250”: the first test was taken before starting to do physical therapy, the second one was taken in the end of physical therapy. We examined the forced expiratory vital capacity (FVC), volume of forced expiration within the first second (FEVı), Gaensler index (FEVı/FVC), peak expiratory flow (PEF), maximum expiratory flow, when 50% of the forced vital capacity has been exhaled (MEF50%). The results of our investigation showed that gymnastic exercises in the water have more positive effect than gymnastic exercises in the sport hall for children with bronchial asthma.
