- Exercise Physiology
- ATP is broken down, ADP + Pi releases heat and energy
- Small amounts of ATP in mitochondria
- ATP must be released quickly
- Accomplished through:
- CP/PC (Creatine phosphate) splitting
- Anaerobic Glycolysis
- Aerobic metabolism
- CP Splitting
- For repeated muscular contractions, rapid replenishment of ATP is necessary
- Splitting of CP --> allows free phosphate to join ADP = ATP made
- For repeated muscular contractions, rapid replenishment of ATP is necessary
- Sufficient for 8-9 seconds --> after, replenishment falls off quickly
- Splitting of CP --> allows free phosphate to join ADP = ATP made
- Splitting of CP --> allows free phosphate to join ADP = ATP made
- Anaerobic Glycolysis
- Uses glycogen to replenish ATP
- Anaerobic Glycolysis
- Glycogen stored in muscle is broken down
- Uses glycogen to replenish ATP
- Uses glycogen to replenish ATP
- Doesn't need oxygen, but makes lactic acid
- Glycogen stored in muscle is broken down
- Glycogen stored in muscle is broken down
- Lactic acid = muscle fatigue
- Doesn't need oxygen, but makes lactic acid
- Doesn't need oxygen, but makes lactic acid
- Tolerance to lactic acid can be built up with training
- Lactic acid = muscle fatigue
- Lactic acid = muscle fatigue
- Aerobic Metabolism
- Produces sustainable energy for long periods of time
- Aerobic Metabolism
- Uses oxygen and fat
- Produces sustainable energy for long periods of time
- Produces sustainable energy for long periods of time
- Complex reaction breaks down fat to glycogen --> used for ATP synthesis
- Uses oxygen and fat
- Uses oxygen and fat
- By-products are carbon dioxide and water
- Complex reaction breaks down fat to glycogen --> used for ATP synthesis
- Complex reaction breaks down fat to glycogen --> used for ATP synthesis
- Used at submaximal intensity
- By-products are carbon dioxide and water
- By-products are carbon dioxide and water
