- Energy systems
- Adenosine triophosphate (ATP)
- Used by body for energy
- 2 seconds worth
- Stored everywhere- floats in the liquid in cells
- Energy is stored in bonds, when broken= energy released
- ATP= ADP+PI+ Energy
- ATP-PC system
- Splits phosphocreatine (muscles)
- By creatine kinase enzyme
- Into creatine and phosphate
- Uses this energy and free phosphate to recycle ATP
- 10 seconds of energy
- Short duration
- High intensity
- E.G. Sprint
- PC= C+ PI+energy
- Splits phosphocreatine (muscles)
- Lactic acid system
- Splits glucose into 2 ATP
- By product is lactic acid
- Just under 1 minute of energy
- Short duration
- High intensity
- E.G. 400m
- Stop exercise at certain PH as the enzymes denature
- Aerobic energy system
- Series of chemical reactions
- 1 glucose= 36 ATP
- Use fat/proteins so less efficient and slower
- Waste products are breathed and sweated out
- 90 minutes of glucose
- Long duration
- Low intensity
- E.G. Marathon
- Glucose+O2= CO2+ H2O+ Energy
- Elite= utilise fat and carbohydrates at the same time
- Novice= hit the wall and use up all 90 minutes of carbohydrates in which they will then switch to using fats
- Adenosine triophosphate (ATP)
