Phosphagen Energy Systems

Phosphagen Energy Systems

1. ATP

   • Adeonsine Triphosphate
     • Universal energy currency
       • Used to pump K+ and Na+ ions
       • Energy made through the hydrolysis of ATP
     • Resynthesize 40-60kg a day
   • 85g in our bodies
   • ATPase is the enzyme which facilitates the break down

2. Creatine

   • Naturally occuring amino acid
   • Endogenously synthesised by the liver, pancreas & kindeys
   • 98% of creatine found in muscle & more than 1/2 in the form of phosphocreatine
     • Phosphocreatine is a high energy molecule

3. ATP-PC System

   • Coupled reaction
   • Duration 8-10 seconds
   • Energy yield 1:1

4. Creatine Supplements

   • Can increase creatine in muscles by:
     • Anaerobic Training and Creatine supplementation
       • 20g per day 4x5g dosage for 5 days
         • Has shown to increase muscle Creatine content in those with low levels.
