Effect of Femoral Blood Flow Occlusion and Release on Ventilation during Exercise and Recovery
Since Zuntz and Geppert11 proposed that exercise-induced hyperpnea is caused by a blood-borne substance, there has been a debate about roles of neural and humoral mechanisms in this phenomenon. Occlusion of blood flow to the leg has been used to eliminate humoral factors. However, this method has led to conflicting results regarding the mechanism of exercise-induced hyperpnea2, 4–7.
