Describe the factors that influence the level of cardiorespiratory fitness a person is able to achieve.
  • The factors that influence cardiorespiratory fitness are age, gender, genetics, body composition, and a person's level of conditioning.
  • The three methods of measuring maximum oxygen intake are the multistage fitness test, the direct VO2 max measurement, and the estimated VO2 max. The multistage fitness test is useful because many people can do the test at once, and the results are reasonably accurate, although it can be difficult to find the audio equipment to play the beeps. The direct VO2 max measurement is very accurate but requires special equipment, which is usually only available to medical professionals. The estimated VO2 max is simple to find and doesn't require activity, but it is the least accurate method of determining maximum oxygen intake.
  • The multistage fitness test is intended to measure a participant's maximum oxygen intake, or VO2 max. The test is similar to a shuttle run. The participant runs between two blocks that are 20 meters apart. They must complete each length before a prerecorded beep sounds. As the test continues, the beeps increase in frequency. The test ends when the participant fails to complete a segment before the beep sounds or if they complete all the runs. Participants then compare their completed level to a chart to find their maximum oxygen intake.

Describe how a multistage fitness test works and what it is intended to do.
  • Males tend to have higher levels of hemoglobin in their blood.
