Does controlled voluntary hyperventilation alter phosphocreatine kinetics and muscle deoxygenation during moderate-intensity exercise in male subjects?
Hyperventilation-induced hypocapnia enhances substrate-level phosphorylation and increases muscle deoxygenation during moderate-intensity exercise, suggesting reduced local muscle perfusion.
Forbes et al. (2007) studied this question.
