|
standardized measure of energy expenditures at rest.
|
|
|
calorie
|
basic unit of heat
|
|
|
direct calorimetry
|
measuring heat
|
|
|
excess postexercise oxygen consumption
|
the "oxygen debt"
|
|
|
fatigue
|
decreased rate of energy delivery anaerobic glycolysis, and oxidative metabolism, accumilation of metabolic by products such as lactate and H4.
|
|
|
indirect calorimetry
|
based on this principle energy expenditure can be determined by measuring respiratory gases.
|
|
|
lactate threshold
|
the point at which blood lactate begins to substantially accumulate above resting concentrations during exercise of increasing intensity.
|
|
|
maximal oxygen uptake
|
widely regarded as the best single measurement of cardiorespiratory endurance or aerobic fitness.
|
|
|
respiratory exchange ratio
|
The ratio between two values: VCO2 and VO2.
|
|
|
VO2 drift
|
a slow increase in VO2 during prolonged submaximal constant power output exercise.
