Question
Submax VO2 Lab Report (Question Style) 1) Discuss reasons why the use of submax cardiovascular tests is necessary in certain situations (rather than using a max test) (25 pts) 2) For the YMCA test, explain how and why the two workloads, their associated heart rates and an estimate of max heart can be used to estimate VO2max. (25 pts) 3) Discuss 3 potential sources of error that could have affected the VO2max estimate during this lab. (25 pts) 4) Explain why bicycle tests may be problematic when they are used to produce an estimate of VO2max (25 pts.)Explanation / Answer
1)Cardiorespiratory fitness tests can be used to gather information that can help you do a number of important things:
1. Assess a client’s current fitness status (VO2max).
2. Create an individualized exercise program based on maximal endurance capacity.
3. Provide feedback on a client’s progress throughout a training program.
4. Provide information to educate and motivate a client.
5. Identify specific limitations (e.g., musculoskeletal) or needs that can affect exercise program design.
6. Under certain circumstances (i.e., maximal exercise testing), evaluate adverse cardiovascular responses to exercise or identify cardiovascular disease risk.
3)potential sources of error for submaximal tests to estimate VO2 max
>poor heart rate measurement
>alterations in heart rate
>behavior (smoking, prior exercise)
>environment: additional stresses, noises
>poor extrapolation
>subject cannot follow metronome
4) • Many people may not be accustomed to cycling
