Energy system Flashcards
1
Q
Factors affecting the energy system
A
- exercises intensity and duration
- energy system thresholds
- o2 transport and supply
- food and fuel available
- enzyme activation levels
- fitness level
2
Q
ATP-PC system
A
- coupled reaction
- anaerobic
- ATP and PC food fuel
- muscle cell sarcoplasm
- ATPase and creatine kinase
- P+C by products
- 1 ATP
- threshold 3-10 secs
3
Q
Lactic acid system
A
- anaerobic
- glycogen to glucose
- muscle cell sarcoplasm
- PFK, LDH
- 2 ATP
- threshold 3 minutes
4
Q
Aerobic system
A
- aerobic
- glucose
- muscle cell sarcoplasm
- PFK, LDH
- 2 ATP
5
Q
Electron transport chain (ETC)
A
- aerobic
- glucose by carbs
- mitochondria, cristae
- 34 ATP
- threshold 3 mins +
6
Q
Krebs cycle
A
- aerobic
- glucose by carbs
- mitochondria
- 2 ATP
7
Q
Excess post exercise oxygen consumption (EPOC)
A
Total amount of o2 required to replace ATP, restore PC and remove lactic acid in the working tissue
8
Q
Onset blood lactate. Accumulation (OBLA)
A
Lactic acid starts to accumulate. High intensity
