Calorimetry |
The measurement of heat energy liberated or absorbed in metabolic processes |
|
|
Spirometry |
An indirect calorimetry method for estimating heart production in which expired assure is measured and analyzed for the amount of oxygen consumed and carbon dioxide produced |
|
|
Oxygen consumption (VO2) |
Technically the amount of oxygen taken up, transported, and used at the cellular level. Commonly labeled as the volume of oxygen consumed |
|
|
Equation for (VO2) |
|
|
|
Carbon dioxide produced (VCO2) |
Technically the amount of carbon dioxide generated during metabolism, primarily from aerobic cellular respiration. Commonly the volume of carbon dioxide produced. |
|
|
Equation for VCO2 |
|
|
|
Oxygen drift |
A situation that occurs in submaximal activity if long duration, of above 70% VO2 max, or in hot and humid conditions where the oxygen consumption increases, despite the fact that oxygen requirement of the activity has not changed |
|
|
Maximal oxygen consumption (VO2 max) |
The highest amount of oxygen an individual van take in, transport and utilize to produce ATP aerobically while breathing air during heavy exercise |
|
|
Respiratory exchange ratio (RER) |
Ratio of the volume of CO2 produced divide by the volume of O2 confined in the body as a whole |
|
|
Respiratory quotient (RQ) |
Ratio of the amount of carbon dioxide produced divided by the amount of oxygen consumed at cellular level |
|
|
Caloric equivalent |
The number of kilocalories produced per liter of oxygen consumed |
|
|
Caloric cost |
Energy expenditure of an activity performed for a specific period of time. It may be expressed as total calories (kcal), calories or kilojoules per minute, out relative to body weight |
|
|
MET |
A unit that represents the MET on multiples of the testing rate of oxygen consumption of any given activity |
|
|
Mechanical efficiency |
The percentage of energy input that appears as useful external work |
|
|
Economy |
The oxygen cost of any activity, but particularly walking out running at varying speeds |
|
|
Velocity at vo2max |
The speed at which an individual can run when working at his or her maximal oxygen consumption based on both submaximal running economy and vo2 max |
