Values are means ± SD, with percentage of predicted values also reported. Pulmonary function tests were performed by spirometry pre- and 5 min postexercise. FVC, forced vital capacity; FEV1, forced expiratory volume in 1 s; FEF25–75, forced expiratory volume in the 25 to 75 percent. No statistically significant changes were seen in any measures of pulmonary function after exercise.
