In 31 asthmatic children, we investigated the change of the structure on the time of living, an amount of exercise by pedmeter and measured pulmonary ventilatory function during 28 weeks swimming training.
The result showed 58.07% of contribution factor to the structure on the time of living on children with asthma and dynamic play time after school were significantly shorter in asthmatic than non-asthmatic children (p<0.05) . After 28 weeks, we could not find any significantly differences of dynamic play time between asthmatic and nonasthmatic children.
An amount of exercise in daily life from the point of view of walking step number by pedmeter were significantly less in aged 6-9 years boys and girls, and aged 10-12 years boys than non-asthmatic children (respectively, p<0.05, p<0.01) . However, after 28 weeks, we could not find any differences between asthmatic and non-asthmatic children.
Forced vital capacity (FVC) and rate of forced expiratory volume on one second (% FEV_1.0) were increased after 28 weeks than the begining of swimming, and we found the strength of their breathing muscles.
On according to perform the great swimming distances (averages 220m in boys, 325m in girls), all asthmatic children became very lively and actively.
