a Left ventricular volume responses from rest to 40 and 60% of maximal aerobic capacity. The top of each bar represents mean end-diastolic volume, the bottom represents mean end-systolic volume and the difference (top–bottom) represents the stroke volume. b Ejection fraction (EF) response from rest to 40 and 60% of maximal aerobic capacity. *P < 0.05 significant difference between T2D and CON. ⁺P < 0.05 significant difference across conditions. ⁺P < 0.05 significant difference between T2D and CON at given intensity. Values are presented as mean ± SE
