Data are mean±SE. CONT=control; MICT=moderate-intensity continuous training; HIIT=high-intensity interval training; LV=left ventricular; PWTd=posterior wall thickness during diastole; SWTd= septal wall thickness during diastole; LVIDd=left ventricle internal dimension during diastole; LVIDs=left ventricular internal dimension during systole.
