Deck 5 - Adaptations

Question 1

True or false, energy systems work in isolation

Answer 1

False. However one is always the predominant supplier for energy

Question 2

Name the muscle fibre type associated with the aerobic system

Answer 2

Type 1 fibres. Slow twitch oxidative

Question 3

Name the muscle fibre type associated with the ATP-PC system

Answer 3

Type 2b fibres. Fast twitch glycolytic

Question 4

Name the muscle fibre type associated with the anaerobic glycolytic system

Answer 4

Type 2a fibres. Fast twitch oxidative

Question 5

What are the two main impacts of increased creatine stores; an adaptation of the energy systems

Answer 5

A performer can exercise anaerobically (higher intensity) for a longer duration. They can produce faster and more powerful repeated movements

Question 6

Explain why, through training, our energy systems adapt to be better able to tolerate lactic acid

Answer 6

Extension of capillary networks, increase in blood flow, increases ability to oxidise pyruvic acid

Question 7

One adaptation is the energy systems becomes able to increase its use of fats. When does fat oxidation increase within an athlete

Answer 7

After 90 minutes to 2 hours. Once glycogen stores are depleted
