1
Q
Description of altitude training
A
- Carried out at high altitude
- Over 2000m / 8000ft above sea level
- Usually for at least 30 days
- There is less oxygen at altitude so less oxygen available to the muscles.
- Body compensates by making more red blood cells
- Oxygen carrying potential therefore increases
2
Q
Benefits of altitude training
A
- Altitude training is an effective way of improving performance in the marathon as the body will have increased the oxygen carrying capacity which means the athlete will be able to run at a high intensity for longer.
- These effects will be the most significant when the athlete competes at sea level where oxygen levels are higher and the athlete is able to use all of the red blood cells to carry oxygen.
- Giving them an advantage over their competitors
3
Q
Disadvantages of altitude training
A
- Altitude sickness can occur which may prevent the athlete from training therefore reducing performance.
- Psychological issues associated with training in unfamiliar surroundings / being away from home could mean they underperform
4
Q
Effort arm = ?
A
Distance of effort to fulcrum
5
Q
Resistance arm = ?
A
Distance of load to fulcrum
6
Q
Mechanical advantage = ?
A
Effort arm / resistance arm
7
Q
If mechanical advantage > 1 this means ………
A
- Mechanical advantage
- More heavier
- Only with 2nd class
8
Q
If mechanical advantage < 1 this means ………….
A
- Mechanical disadvantage
- More range and speed of movement
- Occurs with 1st and 3rd class
9
Q
What is a lever used for?
A
Allows us to create movement
10
Q
What is the first class lever?
A
Effort ——> Fulcrum ——> Load
