The purpose of this study was to determine and evaluate the effect of an acute bout of treadmill exercise on the Forced vital capacity(FVC), Timed vital capacities(FEV_T), and Forced expiratory flow(FEF) in the sedentary subjects. The ventilatory functions of 18 male college students were measured ,before and immediately after 5% grade, 5 MPH, 3 min. (Ex-Ⅰ) or 6 min. (Ex-Ⅱ) treadmill exercise. The measured values also were standardized with height(height ratio) and body surface area(BSA ratio) of each subject. The values, measured and standardized of pre-and post-exercise, were compared each other. The FVC and its height and BSA ratio were not affect by treadmill exercise. The FEV_T and FEF were tend to increase with exercise and especially the increase in FEF_75∼85% and FEF_75% values were statistically significant. Furthermore, similar patterns of changes in height and BSA ratio of FEV_T and FEF were observed. From the above results, it was suggested that forced expiratory flow, especially end portion of expiration, eras increased by treadmill exercise.
