1

Define aerobic capacity

Aerobic capacity is the ability for the body to inhale, transport and utilise 02 to perform a period of sustained aerobic/sub-maximal activity

2

Aerobic capacity is a key aspect of fitness for what sports

When the performer must work sub-maximally for long periods of time

3

Define V02 max (maximal oxygen uptake)

The maximum amount of 02 the body can inspire, transport and utilise per minute during exhaustive exercise

4

What are the 4 factors effecting V02 max

1. Individual physiological make up
2. Age
3. Gender
4. Training

5

What is the effect of individual physiological make up

More effective cardio-vascular and respiratory systems means you have a higher V02 max

6

Explain the effect of individual physiological make up

Individuals with large lung volumes, strong ventricle muscles, more slow oxidative muscle fibres are able to inhale, transport and utilise more 02

7

What is the effect of training on V02 max

By aerobically training you are able to increase your V02 max by 10-20 percent

8

Explain the effects of training on V02 max

Long periods of aerobic training causes cardiac hypertrophy, increased respiratory muscle function, increased levels of red blood cells and mitochondria

9

What effect does age have on V02 max

V02 max peaks at 20 years old and declines by around 1% each year after that

10

Explain the effect of age on VO2 max

Loss of elasticity/recoil of lung, heart and blood vessel muscles and reduces the efficiency of the CV system

11

What effect does gender have on VO2 max

Males tend to have a higher VO2 max than women by 15-30 percent

12

Explain the effect of gender on VO2 max

Males tend to have larger lung and blood volumes and a larger heart to take in and transport more O2. They also tend to have a higher muscle mass to utilise more O2
