1. Fast vs Slow How good are you?

2. SLOW Fibers = Endurance FAST Fibers = Expolsive

3. Meat 1. Light meat versus dark meat?

4. Contractions 2. Powerful contractions versus steady contractions.

5. Respiration 3. Anaerobic versus Aerobic

6. Mitochondria 4. Lots versus little.

7. Fluid 5. Less blood supply versus highly vascular.

8. Energy 6. Use Glycogen versus use fat.

9. Review SLOW –Dark meat –Endurance –Steady –Aerobic –Lots of mito. –More vascular –Use Fat FAST –White meat –Explosive –Powerful Burts –Anaerobic –Little Mito. –Less Blood –Use Glycogen

10. ENDURANCE

11. ANAEROBIC Bursts of intense contractions (Hypertrophy) Fatigue easily *Train by increasing intensity, decreasing reps.

12. Aerobic Anaerobic threshold: If muscle demands stay below supply needs, will stay aerobic. If increased need, shift to anaerobic. *Train increase reps, decrease intensity.
