  This study aimed to compare the electromyographic (EMG) activity among participants with costo-diaphragmatic, mixed or upper costal breathing type. Forty male were classified according to their breathing type into three groups: costo-diaphragmatic, upper costal and mixed breathing type. EMG activity of diaphragm (DIA), external intercostal (EIC), sternocleidomastoid (SCM) and latissimus dorsi (LAT) muscles was recorded in the dorsal, left lateral and ventral decubitus positions, during the following tasks: 1) quiet breathing, 2) speaking, 3) swallowing, and 4) sustained maximal inspiration. DIA activity was higher in upper costal than in costo-diaphragmatic breathing in all tasks and body positions; was higher in mixed than in costo-diaphragmatic breathing in all tasks in the dorsal and ventral decubitus positions and only in task 4 in the left lateral decubitus position; was similar ..
