Values are means ±s.e.m. at rest and during three exercise (EX) workloads (heart rate of 90, 120 and 150 beats min⁻¹). WL, workloads: SV, stroke volume; HR, heart rate; MAP, mean arteial pressure; Q, cardiac output; TVC, total vascular conductance

^*Different from rest (P < 0.05)

^†different from EX90 (P < 0.05)

^‡different from EX120 (P < 0.05).
