What The Fuel Is Going On Here?

• Functional Performance of the Athletic Cell

Food as fuel is incomplete

• Recovery/Healing
• Hormone production/levels
• Lipid Levels
• Body composition
• Mood
• Immune System function
• Durability and Function of tissue
• The building blocks of our body/cells
• Function of the Athletic Cell

• Nutrients Energy Fat or Sugar
• ATP Currency of energy for the body Krebs
  Cycle
• The Pump is Where AMAZING Happens!
• A turbine/rotating machine that smashes a
  Phosphate Group onto ADP to create ATP with each
  turn
• More turns more ATP/Energy

4
Improved Functional Performance of the Athlete

• Provide more ATP to the muscles/heart so they can
  work more/better

Improved Functional Performance of the Athlete

• What drives the pump?
• H Ions flowing into the matrix/mitochondria
• Water Wheel

7
Improved Functional Performance of the Athlete

• Minimize the acid (CO2) in the Mitochondria
• Excess CO2 lowers the PH level in the
  mitochondria and makes it less attractive for H
  ions to want in on the party
• The pump wont spin as much/as fast
• Less ATP less energy source for the
  muscles/heart
• Less function

Improved Functional Performance of the Athlete
2 CO2s will be produced in the Krebs CycleNO
MATTER WHAT!

• Nutrients Energy (ATP)
• Fat vs. Sugar

Fat vs. Sugar
The point
10

• Respiratory Quotient
  CO2 eliminated/O2 Consumed
• .7 for pure fat burn
• 1 for pure sugar burn

11
Fat vs. Sugar

• Practical Applications
• 30 less acid in the cell sounds good
• Bring on the rats!
• 30 Greater cardiac output in fat rats vs. sugar
  rats
• Authors suggest that this affect likely occurs
  within skeletal muscle as well related to more
  ATP available
