Answer: fast rate of ATP, limited store of fuel, PC runs out quickly
- ATP/PC duration
Answer: 8 seconds at max intensity, 12 seconds at low intensity
- ATP/PC cause of fatigue
Answer: depletion of fuel
- ATP/PC by-products
Answer: heat
- ATP/PC rate of recovery
Answer: 2 minutes complete recovery, 30 seconds half recovery
- ATP/PC examples
Answer: 100m sprint, discus, javelin, high jump
- lactic acid source of fuel
Answer: carbohydrates
