Abstract
Motography, combined with stereophotogrammetry or image analysis, was applied for a study on body surface changes during breathing. Quiet respiration produced no observable alterations of the anterior aspect of persons standing upright, whereas forced ventilation elevated and expanded the chest cage. Although remarkable differences of the respiratory movements could be observed for the individual as well as between the persons, quiet respiration seems to depend mainly on diaphragmatic action. Cervical and intercostal muscles, which elevate and widen the chest cage, are involved in enhanced ventilation.
