Substrate Switching Training

Meaning

Substrate Switching Training is a specialized metabolic conditioning strategy designed to enhance the body’s flexibility in efficiently utilizing different energy sources, primarily transitioning between glucose and fatty acids for fuel. This training involves structured periods of nutrient manipulation and exercise designed to improve mitochondrial function and upregulate the enzymatic machinery responsible for beta-oxidation and glucose metabolism. The clinical goal is to improve metabolic health, insulin sensitivity, and endurance capacity. Achieving metabolic flexibility is a hallmark of youthful energy regulation.
