Energy Systems Flashcards
(28 cards)
What does ATP stand for
Adenosine triphosphate
How log does ATP last
6-10 seconds
What type of reaction is the ATP/PC system
Anaerobic Reaction
What is the recovery time for the ATP/PC system
3 minutes (how long it takes to make more ATP)
What is the fuel source for the ATP/PC system
Creatine phosphate
Where is creatine found
In the muscles
What type of sports are used for the ATP/PC system
Short, high intensity sports, e.g - sprinting
What is the ratio of ATP to PC
1:1
what fuel source is stored in the liver and muscle cells
Glycogen
What type of reaction is the lactic acid system
Anaerobic
What is the process of glycogen being broken down
Glycolysis
What is the by-product of glycolysis
Pyruvate
What is pyruvate converted into due to absence of oxygen
Lactate
What is the energy yield in the lactic acid system
1:3
What is the duration of the lactic acid energy system
10 seconds to 2 minutes
What is the recovery time for the lactic acid system
1-2 hours
Why is glucose broken down
To provide energy
Disadvantage of lactic acid system
There is a build up of lactic acid
How long does the aerobic energy system last
2 minutes +
What is the recovery time for the aerobic energy system
24 - 48 hours
How much yield is produced in the aerobic energy system
38
What does EPOC stand for
Excess Post Oxygen Consumption
What is EPOC
There is oxygen dept that needs repaying after aerobic exercise
How does EPOC get repaid
More ATP energy is resynthesised using aerobic system to repay the dept
