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

Abstract

Purpose This study analyzed the effect on the thickness of accessory muscles of respiration, as well as on forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1), during a 20-minute stair-climbing exercise for young male and female adults with and without smoking.
