Overlapping Energy Systems:

All energy systems are working together at any given time. However, depending on Overlapping Energy Systems 1  Canadian Academy of Sports Nutrition.www.caasn.comintensity and duration of an exercise or a sport, one of the systems is usually dominant. In fact, there is always an overlap among the systems with one being the primary source of energy and the others being the secondary.

Abazar`s Classification for Energy Systems:

The energy system which is the primary source of energy for a specific sport or exercise is called the “Dominant Energy System”, and the secondary energy systems are called the “Non – Dominant Energy Systems”. For example, during a 100 meters dash event or lifting a heavy weight, ATP – PCr is the dominant energy system and glycolysis is the non – dominant energy system, whereas during a 200 meters dash or a 100 meters backstroke swimming, glycolysis is the dominant energy system and ATP – PCr and aerobic systems are the non – dominant energy systems.

For energy systems in different sports, see “Athletic Events” under the section of “Sports”.

Understanding the dominant and non – dominant energy systems in different sports helps the sports medicine doctors and sports nutrition advisors give better guidance to athletes to manipulate their energy systems.
