Week 1

Question 1

what are the anearobic systems that provide us with ATP?

Answer 1

• Phosphocreatine system
• ## glycolysis gives us 2 ATP (glucose) & and 3 ATP (glycogen in the muscle)

Question 2

what are the aerobic systems in the body?

Answer 2

• oxidative phosphorylation

Question 3

during a 30 second sprint
1. what happens to PCr
2. what is the contribution of glycolysis
3. does power output decrease. explain why

Answer 3

1. PCr is lower by the end of 30 seconds. contribution is greates up to 10 seconds
2. after 10 seconds glycolysis is the main anearobic contributor to providing energy.
3. power output only decreases slightly because areobic energy system is also a contributes to making ATP which is why power doesnt decrease durasticly.

1. Blood glucose
2. Liver glycogen
