This study analyzed the effects of smoking on expiratory muscle thickness and pulmonary function in 34 (17 smokers, 17 nonsmokers) healthy female volunteers. The thickness of the internal oblique and transverse abdominal muscles was measured at rest and with forced expiration, using a 7.5-MHz linear ultrasonic imaging probe. The measured thickness was converted into the percentage of change in muscle thickness. All subjects performed maximum expiratory flow maneuvers using a spirometer to determine the forced vital capacity, forced expiratory volume in the first second, peak expiratory flow, and forced expiratory volume in 1 s as a percentage of forced vital capacity. There were significant differences in pulmonary function (forced expiratory volume in 1 s as a percentage of forced vital capacity, peak expiratory flow) between the smokers and nonsmokers,as well as significant differences in expiratory muscle thickness (transverse abdominal). This study showed that female smokers have impaired pulmonary function and expiratory muscle contraction.
