S: sedentary control animals; C: continuous moderate intensity training; HIT: high-intensity interval training; LVDD: left ventricular diastolic diameter; LVSD: left ventricular systolic diameter; LVWT: posterior wall shortening velocity; FAC: fractional area change; IRT/RR0.5: isovolumetric relaxation time normalized to the heart rate. Data are expressed as mean ± SD or medians (including the lower quartile and upper quartile). ∗P < 0.05 versus S; #P < 0.05 versus C.
