Abstract des Autors

The relationship between lung function and physical fitness was examined in children participating in the Australian Health and Fitness Survey (1985). Data from 605 boys and 566 girls, aged 9-15 years, were selected for analysis. Lung function indices included the forced vital capacity (FVC) and the forced expiratory volume in one second (FEV1). Cardiovascular fitness indices were PWC170 relative to body weight (PWC170KG, kgm/kg/min) and time required to run 1.6 kilometres (RUNTIME). Maximal oxygen uptake data (MVO2M, ml/kg/min) was obtained from a sub-sample of 79 boys and 52 girls. All children selected were non-smokers with FEV1/FVC ratios >/= 75%. For each sex, predictive equations containing the natural logarithms (In) of age, height, weight, and each of the fitness indices were fitted to the natural logarithms of FVC and FEV1. The natural logarithm of PWC170KG was a significant predictor for FVC and FEV1 in boys only. The natural logarithm of RUNTIME was a significant predictor for FVC and FEV1 in both sexes. However nlog MVO2M was not a significant predictor in any model. Our predictions estimate that for every 1% change in PWC170KG or RUNTIME, lung function changes by 0.1 to 0.2%. Similar cross sectional investigations are required to examine these relationships in adults. Verf.-Referat
