Lactic Acid System• After 10 seconds, the body’s stores of PC are
depleted and ATP must be re-synthesized using a different source:
The Lactic Acid System
• Fuel = Carbohydrates (C6H12O2) i.e. Carbohydrates, Hydrogen and Oxygen

Lactic Acid System• Carbohydrates are stored in the body as.......
• This is stored in the body in two places -
glycogen
muscles and liver

Lactic Acid SystemGlycogen
Glucose
Pyruvic Acid
Lactic Acid
Energy 2 ATP
Glycogen phosphorylase
Phosphofructokinase (PFK)
No O2
Lactate dehydrogenase (LDH)

Summary• Takes place in the Sarcoplasm• Produces 2 ATP• Is Anaerobic• Enzymes = glycogen phosphorylase
phosphofructokinase (PFK) and lactate dehydrogenase (LDH)

Advantages -more stores of glycogen than PC so lasts longer-relatively simple process , so quick-no O2 needed so no delay
Disadvantages-lactic acid – reduced pH(increased acidity)
= prevents enzymes working = fatigue.
