Presentation Transcript

  1. ATP-PC SystemAdenosine Triphosphate PhosphocreatineENERGY SYSTEMS ATP • Other Names: • Phosphogen System • ATP CP • ATP PCr • PC or CP is a quick reserve of high-energy phosphates in skeletal muscle and the brain. • Characteristics: • Anaerobic • Simplest form of energy • Highest power output 100%

  2. ATP-PC SystemAdenosine Triphosphate Phosphocreatine • Length: • instant starting at 3 seconds • 6-10 • 3-15 • Source: • ATP-PC already stored • Energy locked in bond • “Ready to Burst”

  3. ATP-PC SystemAdenosine Triphosphate Phosphocreatine • Energy Storing Molecule: • High energy bond breaks off and now have… ADP + PCr • Examples: • 100m sprint

  4. Anaerobic Glycolysis • Other Names • Glycolytic System • Lactic Acid System • Anaerobic System • Characteristics: • Occurs without O2=lactic acid build-up • High rate of ATP • High Intensity • Enzymatic reactions are necessary which makes it slower than first system

  5. Anaerobic Glycolysis • Length of time: • 10-15 seconds up to 2 minutes • Source of energy: • Glycogen: takes enzymatic reactions to convert • Energy storing molecule: • Glycogen: stored in liver and muscle • Examples: • 400 m run

  6. Reading Questions • Define the term, hyperthermia • Elevated temp • Define the term, Hyponatremia • Level of Sodium too low • Give an example of an athlete who would suffer from Hyponatremia • Endurance longer than 4 hr-6hr • What is the difference between a kcal and a cal? • nothing • What are the kcals per gram found in: • Protein? 4 • Lipids (fat)? 9 • Carbohydrate 4 • Describe the caloric difference between a tablespoon of mayo versus 20 stalks of celery • Same calories
