What is the Origin of Performance Substrate Management?

This concept originates in the specialized field of sports endocrinology, where energy partitioning under stress is paramount for optimizing output. It recognizes that hormonal status dictates which substrate pathway is prioritized. The management aspect implies active, dynamic control over fuel mobilization.

What is the Mechanism of Performance Substrate Management?

The mechanism centers on modulating the counter-regulatory hormones, primarily insulin and glucagon, to govern glucose homeostasis and glycogen sparing. Furthermore, optimal levels of growth hormone and cortisol influence lipolysis, ensuring adequate fatty acid mobilization during prolonged exertion. Effective management coordinates these hormonal signals to match substrate availability with tissue energy requirements seamlessly.

Performance Substrate Management

Meaning

Performance Substrate Management is the clinical discipline focused on maintaining the precise availability and utilization efficiency of primary energy substrates—glucose, fatty acids, and amino acids—to meet immediate and anticipated physiological demands. This management is crucial for sustained high-level function, whether physical or cognitive. We ensure the body has the right fuel source mobilized at the right time. Inadequate management leads to energy deficits and performance decrements.
