Abstract: Twenty-two children with diagnosis of asthma were invited to participate in a study for investigation of the cardiopulmonary fitness of asthmatic children with and without exercise-induced asthma (EIA). All subjects were required to perform two exercise tests: a submaximal exercise challenge test and a cardiopulmonary endurance test. Spirometry respiratory function was measured before and at 3rd 6th 10th and 15th minute after the submaximal exercise challenge test. Children who demonstrated a drop in forced expiratory volume in the first second (FEV1) equal to or more than 10% after the exercise test were classified as EIA while those did not was non-EIA. All subjects were then required to carry out the cardiopulmonary endurance test. Electrocardiogram (ECG), oxygen saturation and blood-pressures were monitored during the endurance test. All subjects were encouraged to perform the test until the point of exhaustion. Eleven children showed a drop in FEV1 equal to or more the 10% after the submaximal exercise challenge test, while eleven subjects did not. Results showed no significant difference in the peak oxygen uptake (VO2peak) in the group with and without EIA. Moreover, there was no significant correlation between VO2peak and the drop in FEV1 This study demonstrated that nearly 70% of the asthmatic children in this study had VO2peak below 90% of the predicted values. Results of this study provide evidence that the physical fitness of asthmatic children in Hong Kong may be below that of children without asthma. Physiotherapists should explore the area in the education of asthmatic children and their parents in the benefits of exercise, the proper way to perform exercises and means to minimize the symptom provocation during daily physical activities.
