The purpose of this study was to examine the effects of treadmill walking speed and elastic chest band (ECB) on respiratory function in healthy young women with limited chest mobility. Twenty women with limited chest mobility were volunteered for this study. The speed of treadmill walking was determined as 3.0 km/hr and 5.5 km/hr. The ECB was set at the level between 8 and 12 ribs. A 10-min treadmill walking at each walking speed was performed with the ECB. Respiratory function was evaluated by forced vital capacity(FVC), forced expiratory volume in one second (FEV1), forced expiratory volume in one second/forced vital capacity (FEV1/FVC), peak expiratory flow(PEF), expiratory reserve volume, vital capacity, inspiratory reserve volume(IRV), Maximum voluntary ventilation(MVV). Measurements were carried out the baseline and after a 3.0 km/hr and 5.5 km/hr of treadmill walking speed. With the ECB, there was statistically significantly different for the FEV1/FVC in the treadmill walking speed of 3.0 km/hr and the PEF in the 5.5 km/hr when comparing those of the baseline (p<.05). In addition, in the treadmill walking speed of 5.5 km/hr, significant differences were found for FVC and MVV between the baseline and no ECB (p<.05). All parameters were significantly different between the baseline and treadmill walking speed of 5.5 km/hr, except values of FEV1/FVC and IRV (p<.05). These findings suggest that treadmill walking speed of 5.5 km/hr is probably more favorable to improve pulmonary function of females with limited chest mobility than the 3.0 km/hr, with incorporating of the ECB. Further studies need to evidence the generality of our results.
