Percent changes in parameters of right cardiac function after 30-min dive in each combination of pressure breathing and physical activity. StPP, static dive with positive transpulmonary pressure; StNP, static dive with negative transpulmonary pressure; ExPP, continuous finning dive with positive transpulmonary pressure; ExNP, continuous finning dive with negative transpulmonary pressure; IVC diam, diameter of inferior vena cava; RA area, right atrial area; RV/LV, ratio of right to left ventricle end-diastolic area; RVFAC, right ventricle fractional area change; TAPSE tricuspid annular plane systolic excursion; sPAP, systolic pulmonary arterial pressure. *p < 0.05 significant difference between ExPP and StPP or ExNP and StNP; #p < 0.05 significant difference between ExPP and StNP or ExNP and StPP; $p < 0.05 significant difference between ExNP and ExPP. Two-way analysis of variance (ANOVA) with repeated-measures and the post hoc Holm–Sidak test were used to compare the four conditions in each variable
