Document Summary
Understand the concepts and definitions of vo2max, vo2, submaximal, maximal, indirect, direct, gross, net, field test, laboratory test, relative, absolute. Vo2 max- capacity of the heart, lungs, blood to deliver oxygen to working muscles during dynamic exercisess involving large muscle mass. Vo2 calculated at rest, sitting or lying down, not moving. Submaximal does not require patients to go to max, no exhaustion but still tirring, 60 to 80% of max. Indirect indirectly measure oxygen based on heart rate response, time to complete tasks. Direct- directly measure expired air to quantify actual oxygen consumption. Field- tests that can be done outside and in the lab. Lab only done in the lab with equipment. Provides measure of energy consumption for non-weight bearing exercise. Takes into account body mass; men typically weigh more. Done with large group but not desirable for accurate measurement. Max- calculated prior to starting vigorous exercise program, older men and women are tested most often.
