What the study found
The review explains lactate exchange between organs, cells and cellular compartments, supporting its role as an energy substrate rather than merely a waste product.
Participants and protocol
The article synthesizes isotope-tracer, blood-flow and tissue-measurement research underlying lactate-shuttle theory.
What this cannot establish
Mechanistic physiology does not identify an individual's threshold pace or show that a particular workout or lactate supplement improves racing. Training prescriptions require separate evidence.
