Proper Nutrition Positively Impacts Recovery after Exercise
  • Glycogen Depletion and Repletion
2
What is Glycogen?
  • Blood sugar stored in the liver, muscles, and to a lesser extent the bloodstream.


3
What is Glycogen?
  • Blood sugar stored in the liver, muscles, and to a lesser extent the bloodstream.


  • Glycogen helps to fuel muscle contractions.
4
How is Glycogen Used?
  • Energy!
5
How is Glycogen Used?
  • Energy!
  • From carbohydrates and fat
6
How is Glycogen Used?
  • Energy!
  • From carbohydrates and fat
  • Carbs stored in liver and muscles as glycogen
7
How is Glycogen Used?
  • Energy!
  • From carbohydrates and fat
  • Carbs stored in liver and muscles as glycogen
  • Glycogen is quickly converted into glucose during exercise
8
How is Glycogen Used?
  • High intensity (anaerobic) exercise:
    • Use large amounts of energy
9
How is Glycogen Used?
  • High intensity (anaerobic) exercise:
    • Use large amounts of energy
    • Main source of fuel is glucose
10
How is Glycogen Used?
  • High intensity (anaerobic) exercise:
    • Use large amounts of energy
    • Main source of fuel is glucose
  • Low intensity exercise
    (aerobic):
    • Glycogen from carbs is the main fuel, then fat

14
Diet and Glycogen
  • Control with proper diet
15
Diet and Glycogen
  • Control with proper diet
  • Build up glycogen stores
16
Diet and Glycogen
  • Control with proper diet
  • Build up glycogen stores
  • Repletion of glycogen stores will not happen without eating

28
Diet impacts Exercise
  • Review
  • Glucose from carbs burned first and faster
29
Diet impacts Exercise
  • Review
  • Glucose from carbs burned first and faster
  • Fat is burned more slowly
30
Diet impacts Exercise
  • Review
  • Glucose from carbs burned first and faster
  • Fat is burned more slowly
  • Only after carb stores are depleted


31
Diet impacts Exercise
  • Review
  • Glucose from carbs burned first and faster
  • Fat is burned more slowly and
  • Only after carb stores are depleted


  • Eat right to maximize                          your training and performance!
