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

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

20 Muscle Performance Fast fibers

30 Muscle Performance *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…
