Abstract
The present work investigated the effect of different breathing strategies performed with and without body immobilization on postural performance. Sway amplitude and mean velocity of center of pressure displacement in the anteroposterior and mediolateral planes were assessed by the force platform in 48 healthy volunteers. Balance was estimated during quiet breath, inspiratory, expiratory breath holding and hyperventilation with and without immobilization of the neck, trunk, hip, and knee joints. In general, restriction of body mobility caused a reduction of the postural stability in anteroposterior plane, while mediolateral body sway decreased. Our results imply that body immobilization reduced the ability to compensate respiratory disturbances in the anteroposterior direction and, on the contrary, facilitated mamtaining balance in the mediolateral plane.
