active recovery
performance of light physical activity immediately after an exercise bout to aid recovery
adenosine triphosphate (ATP)
a high energy phosphate molecule synthesized and used by cells for energy to perform cellular activities
adenosine diphosphate (ADP)
a molecule that combines with an in-organic phosphate to form ATP
aerobic metabolism
second stage of metabolism, requiring the presence of oxygen, in which the breakdown of glucose (in a process called the Krebs or citric acid cycle) yields a high amount of energy.
anabolic reaction
a process in which simple substances are synthesized into more complex substances.
anaerobic metabolism
The metabolism that takes place in the absence of oxygen; the principle product is lactic acid.
ATP-PC System
use of energy obtained from intramuscular ATP and phosphocreatine stores to perform cellular activities, normally utilized during short-duration, high-intentsity physical activity
Basal metabolic Rate (BMR)
metabolic rate determined in a thermal neutral environment, 12 to 18 hours after a meal, immediately after rising in a resting, supine position.
Beta oxidation
breaking down fatty acids to acetyl CoA units
chemical process involved in the production and breakdown of cellular ATP
catabolic reaction
a process in which complex substances are broken down into simpler substances, yielding energy
The removal of an amino group (-NH2) from an amino acid or other organic compound.
direct calorimetry
determination of the metabolic rate of an organism by direct measurement of the amount of heat produced.
electron transport chain (ETC)
a series of chemical reactions that take place in the mitochondria, involving cytochromes, that result in the production of ATP and water
a protein molecule that lowers the energy of activation and in doing so facilitates a chemical reaction.
essential amino acid
an amino acid that the human body can't synthesize
excess post oxygen consumption (EPOC)
the additional oxygen consumed above resting value after an exercise bout that is utilized to aid in many recovery processes a similar term is oxygen
fatty acid
a compound composed of a carbon chain and hydrogen atoms with and acid group (COOH) at one end and a methyl group (CH3) at the other
Flavin adenine dinucleotide
one of the several molecules that serve as an electron and hydrogen carrier in bioenregetics
