Types of fibers

Types of fibers

Are classified according to
1. Speed of contraction and fatigue resistance
  1. Exists
    1. Type II and Type II (A and B)
Type I fiber
1. slow twitch (oxidative )
  1. dependent phosphorylation
    1. Contraction: contraction lasts 10 times longer than fast twitch fibers
Type II fiber (A and B)
1. Type IIA: oxidative glycolytic fibers
  1. Fast contraction
    1. Type IIB: Glycolytic fibers
      1. Fast contraction and fast fatigue
2. Divide faster ATP
  1. and
    1. speed of contraction depends:
      1. On the myosin heads
        And the type of fiber
Myoglobin
1. Red pigment fixer oxygen
  1. Depending in the amount of myoglobin
    1. Classified fibers
      1. Oxidative: red muscle and Glycolytic: white muscle
