Assessing Cardiorespiratory Fitness

A series of vocabulary flashcards based on key concepts related to assessing cardiorespiratory fitness.

VO2max

Maximal oxygen uptake; the maximal ability of the heart, lungs, and blood to deliver oxygen to working muscles during dynamic exercise.

VO2peak

The highest oxygen consumption achieved during an exercise test, which may vary in relation to VO2max.

Absolute VO2

Measured in liters per minute (L/min) or milliliters per minute (ml/min) without reference to body mass, typically used for non-weight-bearing exercises.

Relative VO2

Expressed relative to body mass in milliliters per kilogram per minute (ml/kg/min), allowing comparisons of cardiorespiratory fitness across different body sizes.

Gross VO2

Total oxygen consumption during both rest and exercise.

Net VO2

Oxygen consumption of exercise only, excluding resting consumption.

Maximal exertion test

A test that measures VO2max directly, requiring expensive equipment and trained personnel.

Submaximal exertion test

A test that estimates VO2max and can be performed with lower costs and time requirements.

HRmax determination

The maximum heart rate, which is crucial for accurate testing and exercise prescription.

APHRmax

Age-predicted heart rate maximum, calculated typically as 220 minus age.

RPE

Rating of Perceived Exertion, a scale used to measure exercise intensity based on an individual's subjective perception.
