Standardization of Exercise Tests in Asthmatic Children

Abstract: . Standardization of exercise tests in asthmatic children. Asthmatic children, known to be susceptible to exercise-induced bronchoconstriction, exercised by running or walking on a treadmill. Changes in airways obstruction were estimated by measurement of peak expiratory flow rate before, during, and after exercise. Post exercise bronchoconstriction reached a maximum when the duration of exercise was 6 to 8 minutes and when the gradient of the treadmill was 10 to 15%; exercise for longer periods or at steeper … Show more

“…O fator de correção de valores foi em BTPS (temperatura do corpo, pressão ambiente e saturação de vapor d'água). Dessa forma, cada criança tem o seu padrão das variáveis da função pulmonar (Crapo, Morris & Gardener, 1981;Silverman, & Anderson, 1977).…”

“…The studies of children running on a treadmill by Silverman Sc Anderson (39) showed increasing amounts of EIA with increasing duration of exercise up to 6 min, but not longer, and with increasing severity of work load up to about 60-80% of their predicted maximum oxygen consumption. This corresponded to a heart rate of about 180 per minute.…”

“…Using the percentage changes, no relationship has generally been observed between the pre-exercise level of lung function and the severity of EIA in children (42,38), i,e., the children with better resting levels had greater absolute falls in lung function. In complete contrast, careful studies in adults have shown smaller changes in patients with better baseline values (25).…”
