Description

The present study evaluates the effect of leaning forward on lung volume and breathing. Static lung volume and thoracoabdominal diameter were measured in 20 healthy volunteers while standing upright and leaning forward at angles of 30°, 60°, and 90°. With an increase in forward angles, the end inspiratory and end expiratory lung volumes significantly increased, but those did not differ significantly between the angles of 60° and 90°. The end inspiratory and expiratory thoracic diameter significantly increased with increasing forward lean. These results suggest that lung volume may increase when the body lean forward due to the increase in thoracic diameter caused by the altered direction of gravitational forces acting upon the rib cage.
