The ATP-PC System Flashcards
1
Q
What type of energy system is the ATP-PC system
A
Anaerobic
2
Q
What is the fuel source for the ATP-PC system
A
Creatine phosphate (PC)
3
Q
What is the duration of the ATP-PC system
A
6-10 seconds
4
Q
What is the recovery time for the ATP-PC system
A
About 3 mins
5
Q
Which sports would the ATP-PC system be used in
A
Sports requiring explosive power (sprinter, power lifter)
6
Q
What are the steps in the ATP-PC system
A
- ATP requires resynthesizing
- Creatine phosphate (fuel source) is present in the muscle cell
- Creatine phosphate is broken down to provide the energy required
- One PC molecule produced one new ATP molecule
7
Q
What are the benefits/disadvantages of the system
A
Benefits
- PC is stored in the muscle, so is readily available to be used
- no oxygen is required (anaerobic)
- simple reaction means that energy production can happen very quickly
- no negative by products
Disadvantages
- only sustains muscle for approx 10 seconds
