Transcript

  • 1. MODULE 7 - FATS AS A SOURCE OF ENERGY DURING EXERCISE
  • 2. a) REQUIREMENT
  • 3. REQUIREMENT OF FATWhen the calorie requirement for an athlete is high, fat is necessary to make up for the deficit as it is a more concentrated form of energy. 1 g fat gives 9KCalIf an athlete tries to restrict fat completely, he may not be able to consume enough food to provide the desired amount of energy for the activity.
  • 4. Fat as an energy substrate
  • 5. Activity
  • 6. Fat: Low Power Fuel• Slow ATP production -- Fat can only produce ATP via aerobic metabolism• Primary use by slow twitch muscle fibers (recruited during low-moderate intensity exercise)
  • 7. b) REGULATION OF FAT METABOLISM
  • 8. Energy Release from FatAdipocytes - Adipose tissue serves as an active and majorsupplier of fatty acid molecules.
  • 9. Hormonal EffectsBreak down of glycerol and fatty acids
  • 10. Lipogenesis
  • 11. ChylomicronMicelleApoproteinPhospholipid
  • 12. c) FACTORS AFFECTING USE OF FAT DURING EXERCISE
  • 13. FACTORS AFFECTING USE OF FAT DURINGEXERCISE1. Exercise intensity2. Exercise duration3. Training experience
  • 14. • Prolonged continuous, moderate to intense activity that places high demands on aerobic metabolism.• Physical activity performed at 70% VO2max over long duration involves a significant amount of fat oxidation.• Endurance training promotes the use of intramuscular triglycerides as fuel substrates for exercise• Increased fat oxidation as a result of endurance training is associated with decreased muscle glycogen use and improved endurance performance.
  • 15. Note the following changes insubstrate contribution to the totalenergy supply as energy intensityincreases from 25% to 65% to 85% ofVO2max: • Muscle glycogen use increases. • Muscle triglyceride use increases at 65% and then lessons at 85% VO2max. • Plasma fatty acids use decreases. • Total fat oxidation is the highest at 65% VO2max. • Plasma glucose use increases. • Total carbohydrate use is highest at 85% VO2max.
  • 16. What does 100g of fat look like in food?
  • 17. ACTIVITY: A short recap, firstFueling Tips for Athletes: Before exercise training or competition • Choose high-carbohydrate, low-fat foods you like. • Eat foods and drink fluids that are familiar and comfortable. • Choose foods you digest easily. • Carbohydrate digests most quickly. • Protein digests more slowly. • Fat (especially fried foods) digests most slowly. • Highly concentrated foods (energy gels, energy bars) slow digestion. • Fiber in foods slows movement of food out of the stomach. • Larger volumes (gulps) of fluid exit the stomach faster than smaller volumes (sips). • Eat a meal or snack every 2-3 hours on training days. • Eat meals about three hours before exercise. • Eat less food if eating within two hours of exercise. • Fuel with liquids or a small snack an hour (or less) before exercise. • Anxiety, stress, and high intensity exercise slow digestion. • Try new foods in training situations, not competitions
