In an attempt to compare most of the available pulmonary function tests in detecting airway obstruction after exercise, two studies were conducted. In the first study 24 bronchodilator-dependent asthmatic boys were evaluated before treadmill exercise (baseline) and at 7 and 30 minutes afterwards. The following pulmonary function parameters were measured: forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximum mid expiratory flow (MMEF), peak expiratory flow rate, thoracic gas volume, airway resistance, specific airway conductance (SGaw), and closing volume (CV). Results showed that SGaw, MMEF, and CV were the most sensitive parameters reflecting changes in airway caliber. Less significant changes also appeared in FEV1 and in FVC. The significance of these changes and their relationships to other parameters are discussed. In an attempt to better understand the effects of airway obstruction...
