Values are means ± SEM. HR, heart rate; MAP, mean arterial pressure; LVESP, LV end-systolic pressure; LVEDP, LV end-diastolic pressure; dP/dtmax, maximal slope of the systolic pressure increment; dP/dtmin, maximal slope of the diastolic pressure decrement; LVEDV, LV end-diastolic volume; LVESV, LV end-systolic volume; EF, ejection fraction. ∗p < 0.05 vs. MCo, #p < 0.05 vs. FCo. pi: interaction value (factors: gender and exercise) of two-way analysis of variance (ANOVA).
