Energy Systems Flashcards
Definition: Adenosine Diphosphate (ADP)
A by-product that results when ATP breaks down and loses one of its phosphate groups located at the end of the molecule
Definition: Adenosine Triphosphate (ATP)
A high-energy molecule stored in muscle cells and other parts of the body
Definition: Aerobic System
Provides energy for the for the resynthesis of ATP through the breakdown of various energy fuels (mainly glycogen and triglycerides) through a series of chemical steps that require oxygen
Definition: Anaerobic Glycolysis System
Provides energy for the resynthesis of ATP through the incomplete breakdown of glycogen through a series of chemical steps that do not require oxygen
Definition: ATP/PC System
Provides energy for the resynthesis of ATP through the breakdown of creatine phosphate without oxygen being involved
Definition: Creatine Phosphate (CP)
A chemical compound found in muscle cells that is capable of storing and releasing energy that can be used to reynthesise ATP
Definition: Intensity
The exertion level or how hard the training is being performed
Definition: Metabolic by-products
A substance produced as a result of chemical reactions within the body associated with the production of energy for ATP resynthesis
Definition: Phosphocreatine (PC)
A chemical fuel consisting of a bound phosphate and creatine molecule stored in musckes and split rapidly to rebuild ATP during explosive activities
Definition: Rate
Refers to how quickly ATP is resynthesised
Definition: Time/Duration
The length of a work interval within a training session
Definition: Yield
The total amount of ATP that is resynthesised during an exercise bout.
Definition: ATP Resynthesis
Refers to a process where ATP is rebuilt or ‘recharged’ (ADP + Pi = ATP)
Definition: Energy System Interplay
When all three energy systems work together to contribute to energy production
Definition: Glycolysis
The breakdown of Glycogen
