  1. Comparison of baseline variables between study groups. MCT (n = 24): moderate continuous training. HIIT (n = 24) High-intensity interval training. sPAP [mmHg] Systolic pulmonary artery pressure on transthoracic echocardiography. TAPSE [mmHg] Tricuspid annular plane systolic excursion on transthoracic echocardiography. NTproBNP [pg/ml] N-terminal prohormone of brain natriuretic peptide. Mean values ± standard deviations are depicted. Significance is denoted with an asterisk (p < .05). Differences were assessed with t testing
