Data are presented as mean ± SD. IC = inspiratory capacity; θDIA = phase shift angle between abdominal ribcage compartment and abdomen compartment; θRC = phase shift angle between pulmonary ribcage and abdominal ribcage compartment; TV = tidal volumes during quiet breathing. See Table 1 legend for expansion of other abbreviations.
