Figure 3. Cardiac output, heart rate, stroke volume, central venous pressure, mean arterial pressure, systemic vascular conductance, O₂delivery, a-v O₂diff, O₂ extraction and O₂uptake at rest, during submaximal and maximal exercise and during 10 min of recovery in heat stress and control trials.

Data are means ±s.e.m. for 6 subjects. Lower than peak value during maximal exercise, P < 0.05.
