Course overview

Energy Systems

During exercise, your body relies on three basic energy systems: the anaerobic a-lactic system, the anaerobic lactic system, and the aerobic system. Depending on the sports played or exercise type, athletes rely on one system more than the other to deliver the body with the adequate energy required for the activity.

Purpose of understanding Energy Systems of Athletes

Coaches and Sport staff (Exercise Professionals and Clinicians) are required to understand the basics of energy systems that underscore exercise and sport participation.

What's in-store

Similar to an engine that needs "fuel" to move the components of an engine, muscles need "energy" to function We will explore the physiological principles underlying the the different energy systems of athletes. The type of energy that is used to produce contractions in the muscles is an energy source called Adenosine Triphosphate (ATP). ATP is a molecule, (a so-called high octane fuel), that releases the energy needed for muscle contraction.
