Energy Systems Flashcards
1
Q
ATP-PC System
A
High intensity anaerobic exercise (dominant for first 10 seconds)
2
Q
Anaerboic Glycolytic (Lactic Acid)
A
Medium to high intensity, anaerboic exercise (dominant for 30 seconds to about 3 minutes)
3
Q
Aerboic System
A
Low to medium intensity, aerobic exercise (dominat for about 3 minutes +)
4
Q
Energy System Interplay (Energy Continuum)
A
The process of all 3 energy systems working together to produce a constant supply of ATP to power the muscles
5
Q
Advantages of the ATP-PC System
A
- ATP can be re-synthesised rapidly
- PC stores can be re-synthesised rapidly
- No fatiguing products
- Can extend the duration of ATP-PC system through creatine supplementation
6
Q
Disadvantages of ATP-PC system
A
- Only a limited supply of PC in the muscle cell (lasts 10secs)
- Only one mole ATP produce for every mole of PC
- PC re-synthesis can only take place in the presence of oxygen (low intensity exercise)
7
Q
Advantages of the Anaerobic glycolytic system
A
- ATP can be re-synthesised quite quickly due to very few chemical reactions and lasts longer the the ATP-PC system
- In the presence of oxygen lactic acid can be converted back into liver glycogen
- Can be used for a sprint finish
8
Q
Disadvantages of Anaerobic glycolytic system
A
- Lactic acid as a by product which denatures enzymes and prevents them increasing the rate at which chemical reactions occur
- Only a small amount of energy can be released from glycogen anaerobically (5% conspired to 95% aerobically)
9
Q
Advantages of Aerobic system
A
- More ATP can be produced (36 ATP)
- No fatiguing by products
- Lots of glycogen and triglyceride stores so exercise can last a long time
10
Q
Disadvantages of Aerobic System
A
- Complicated system so cannot be used straight away. Takes a while for enough oxygen to become available to meet the demands of the activity and ensure glycogen and fatty acids are completely broken down
- Fatty acid transportation to muscles is low and also requires 15% more oxygen to be broken down than glycogen
