Comparison of the Respiratory Muscle Thickness and Lung Capacities during Stairs Up-Down between Individuals with and without Smoking

Background It is known that smoking reduces the effectiveness of aerobic exercises and can have negative effects throughout body. Purpose This study analyzed effect on thickness accessory muscles respiration, as well forced vital capacity (FVC) expiratory volume in 1 second (FEV1), during a 20-minute stair-climbing exercise for young male female adults with without smoking. Study design Pre-test post-test control group Methods Twenty subjects were divided into two groups [smokers (n=10) non-smokers (n= 10)]. measured changes sternocleidomastoid pectoralis minor muscle, FVC FEV1. Results The results showed increased significantly both smoker non-smoker after exercise, although muscle more among smokers compared to non-smokers. In contrast, no significant differences FEV1 observed between groups. Conclusions Based this study, should understand increases respiration while ascending descending stairs interfere normal breathing patterns.
