Short answer Flashcards
Why should you undergo some form of screening before commencing any exercise program
- To help identify any health conditions that might be made worse by exercise
- Help identify individual limitations
- Provides baseline for comparison
Validity
Assessment of the extent to which a test measures what it is supposed to measure
Problem of validity arises when…
The direct measurement of a certain capacity cannot be done easily
Discuss the validity of using the sit and reach test as a surrogate test for flexibility
- Directly measures trunk flexion range of motion
- May not accurately represent the range of motion of other joints (flexibility varies between areas of the body)
How is inter-rater reliability improved
- Providing clear set of specific instructions (prevents misinterpretation)
- Ensure standardised equipment
- Provide training for assessors
Define oxygen debt
Describes the deficit between O2 requirement (when exercising at a particular intensity) and the current state of O2 consumption
How can warming up can reduce oxygen debt at the beginning of a high intensity exercise effort
Warm up activities enable the body to gradually increase O2 consumption so when ready to commence high-intensity work, the level of O2 consumption is elevated from resting level
Explain why individuals who choose a vegan lifestyle need to ensure that they
eat a wide variety of protein foods
- Important macronutrients that cannot be synthesised in the body so sufficient intake is essential
- Most protein rich foods are animals products, thus need to consume variety of other foods
Define glycaemic index
Provides an indication of how quickly a particular food item raises blood glucose
Define glycaemic load
Determines the degree to which the blood glucose is raised after eating a particular amount of a food.
Which should you pay attention to if you are concern about blood sugar level? Glycaemic load or index
As glycaemic load takes into account both the amount of glucose and the rate at which it could be absorbed, it is a better indicator of the extent to which the blood sugar level will be affected.
