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