- lactic acid system
- where?
- sarcoplasm
- energy yield?
- 1:2
- how long?
- 10-120 seconds
- example
- 300m/400m sprint
- active enzymes
- 1st reaction = glucogen phosphorylas-e (GPP)
- 2nd reaction = phosphofructo-kinase (PFK)
- 3rd reaction = lactate dehydrogenas-e (LDH)
- effect of lactic acid
- reduces PH
- increases acidity
- inhibits enzymes
- causes fatigue
- stimulates pain receptors
- recovery of 1-4 hours
- advantages
- quick O2 not required
- energy for 2-3 mins
- higher yield ration than PC
- lactic acid can be used as a fuel
- disadvantages
- build up of lactic acid
- low energy yield compacred to aerobic energy system
- up to an hour recovery
- where?
