Regulation of Increased Blood Flow (Hyperemia) to
The distribution of blood flow to the arms and legs in a hypothetical elite cross-country skier during heavy exercise. The left panel shows that legs receive ∼20 l/min of blood flow during maximal diagonal skiing with only modest arm effort. Under these circumstances, cardiac output exceeds 30 l/min and mean arterial pressure (MAP) is ∼95 mmHg.
