운동유발성 천식환아에서 준비운동의 예방효과에 대한 연구
김황민,김규언,이기영 대한천식알레르기학회 1987 천식 및 알레르기 Vol.7 No.2
One hundred and twenty three cases(92 male and 31 female)of asthmatic children ranging in age from 4 to 15 years underwent pulmonary function tests before and after exercise to detect exercise-induced asthma(EIA). If the peak expiratory flow rate(PEFR), measured with Wrights peak flow meter, decreased by 15% or more after an exercise loading test(the running up and down the stairs method for 6 minutes), the result was considered positive. Of 123 cases, 48 patients were confirmed to have EIA. To determine the effect of a warm-up on EIA, forty eight EIA cases took part in warming-up(fast walking, but not to the extent of shortness of breath, for I 5 minutes) and then rested for 15 minutes before the exercise load test was prefomed. If the PEFR after the warming-up had decreased by 15% or less, it was considered that the warming-up had a preventive effect on EIA. The results were as follows: 1. The baseline value of %PEFR in non-EIA cases (9I.07%) was not significantly lower than the predicted value for PEFR at different ages, but in the EIA cases the baseline value of %PEFR was decreased to 76.35%. 2. The baseline value of %PEFR was decreased
