identify a risk of intermittent hypoxic training
disruption of training
Explain how age may account for differences in VO2 max inbetween two athletes
- from early 20s onwards VO2 max decreases
- Due to reduced elasticity in heart
Explain how gender may account for differences in VO2 max between two athletes
2 marks
- females tend to have lower VO2 max
- due to small lung volumes

A footballer is practicing free kicks. After contact one ball travels in a straight line and another swerved right.
Explain the effect of the application of force on the resulting motion of each ball in flight.
4 marks
- Ball travelling in straight line has linear motion
- (application of) a direct force / through CoM

- Air travels further over top of ski jumper
- Air travels faster over top of ski jumper
- creates a pressure gradient
- Air moves from area of high to low pressure
