- Energy Systems
- Aerobic energy system
- Glycolysis
- The process of breaking down glycogen into pyruvic acid
- 4 ATP Produced
- Occurs in the sarcoplasm of muscle cells
- Krebs Cycle
- Series of chemical reactions in the mitochondria
- Oxidises acetyl coenzyme A to carbon dioxide
- 2 ATP are used
- Electron Transport Chain
- 34 molecules of ATP are produced
- Hydrogen is oxidised to qater
- Training effects
- Increase cardiac hypertrophy and resting stroke volume
- Decrease resting heart rate
- Increased blood volume and haemoglobin levels
- Increased muscle stores of glycogen
- Increased cappilarisation of muscles
- Increased number of mitochondria
- Glycolysis
- Anaerobic energy system
- ATP-PC Energy System
- Every molecule of PC broken down, sufficient energy is released to resynthesise one molecule of ATP
- Sporting Example: SPRINTING
- Positives
- No waste products are made
- energy is released rapidly
- PC - C + P + ENERGY
- ENERGY + ADP + P -ATP
- ENERGY + ADP + P -ATP
- Negatives
- Stores are limited
- stores take time to replenish
- Lactate anaerobic energy system
- Produces energy for ATP resynthesis by
- Breaks down glucose without oxygen
- Produces lactate as a by products
- ATP-PC Energy System
- Aerobic energy system
- Resynthesis
