Glossary

Concept 8: Cardiovascular Fitness



Aerobic Capacity
  A measure of aerobic or cardiovascular fitness; another term used for maximum oxygen uptake (VO2 max).
 
Anaerobic Capacity
  A measure of anaerobic fitness; the maximal work performed in a short burst of high-intensity exercise.
 
Heart Rate Reserve
  The difference between your maximum heart rate (highest heart rate in vigorous activity) and your resting heart rate (lowest heart rate at rest).
 
Hemoglobin
  Oxygen-carrying pigment of the red blood cells.
 
Lactic Acid
  Substance that results from the process of supplying energy during anaerobic exercise; a cause of muscle fatigue.
 
Maximum Oxygen Uptake (VO2 Max)
  A laboratory measure held to be the best measure of cardiovascular fitness. Commonly referred to as VO2 max or the volume (V) of oxygen used when a person reaches his or her maximum (max) ability to supply it during exercise.
 
Oxygen Uptake Reserve (VO2R)
  This is the difference between your maximum oxygen uptake and your resting oxygen uptake. A percentage of this value is often used to determine appropriate intensities for physical activities.
 
Performance Benefit
  In this concept, performance benefit refers to an improved score on a cardiovascular fitness test or in performance of activities requiring cardiovascular fitness.
 
Ratings of Perceived Exertion (RPE)
  The assessment of the intensity of exercise based on how the participant feels; a subjective assessment of effort.
 
Resting Oxygen Uptake
  This is the amount (volume) of oxygen used at rest-also called resting metabolism. One MET is another unit of measure representing resting oxygen uptake.
