Definition
- Adenosine triphosphate
-
The currency of energy. Its unstable nature as a molecule lends itself to liberation of potential energy and therefore fuelling work. Hydrolysis of ATP to ADP in the cell releases a great amount of energy.
Aliases: ATP
- Aerobic
-
In the presence of oxygen; aerobic metabolism utilizes oxygen
- Anaerobic
-
Literally, "without oxygen." Exercise that demands more oxygen than the heart and lungs can supply. Anaerobic contribution to energy turnover increases above the intensity of the lactate threshold.
- Anaerobic work capacity
-
Defined as the maximum amount of work that can be produced from anaerobic energy systems. Can be derived at the same time as the Critical Power from the power-time relationship.
- Anaerobic-endurance
-
The ability to sustain work supported to a significant extent by anaerobic metabolism. Could be thought of as tolerance of exercise around and above the maximal lactate steady state (i.e. upper limit of lactate production / clearance balance).
