[Exercised-induced asthma in soccer players ages from 8 to 13 years].

The purpose of this study was the detection of exercise induced asthma in soccer players aged 8-13 years. Thirty boys, 8-13 years old participated in the study. They were coming from an athletic team of north of Thessaloniki. The study included clinical examination, administration of a respiratory health questionnaire and the exercise -- free running -- test with spirometric measurements. Spirometric measurements were performed by using a microspirometer, before exercise and 2, 5, 10, 15 and 30 min after a 6 min free running exercise (80 - 90 % max heart rate). The highest forced expiratory volume in one second (FEV (1)) value before exercise was compared with the lowest of post exercise values. The results showed a decline in FEV (1) > 15 % in 12 out of 30 children. Particularly, decline in FEV (1) was present in 1 (11 %) out of 9 children with free personal medical history but positive family history for asthma, in 3 (25 %) out of 12 children with allergies, and in 8 (89 %) out of 9 children with asthma. Symptoms were reported by 9 of 12 children with fall in FEV (1) > 15 %, during the 6 min exercise test, who had no symptoms during the soccer games. Identification of EIA by exercise challenge test in young athletes is a useful component for the diagnosis of bronchial hyperresponsiveness. Similar studies should be performed on older and younger athletes who participate in different sports and games.
