10 Muscle Performance *What are the two keys to muscle performance?

1. Types of fibers in muscle 2. Physical conditioning or training 10 Muscle Performance

20. *Majority of muscle fibers in the body *Large in diameter *Large glycogen reserves *Few mitochondria *Rely on glycolysis *Rapidly fatigued These characteristics describe…

Fast fibers 20 Muscle Performance

30 *About ½ the diameter of, and 3X slower than, fast fibers *Fatigue resistant because: -oxygen supply is greater due to more perfusion -myoglobin stores oxygen in the fibers -oxygen use is efficient due to large numbers of mitochondria These characteristics describe… Muscle Performance

30 Slow fibers
