distinguish between two physiological types of muscle
fibers, and explain their functional roles;
Muscle fiber referred to as the muscle cells present within the muscle. They are principally responsible for regulating the body's physical forces and helps to facilitate an organized movement.
The two types of muscle fibers based on physiology are slow oxidative and fast oxidative muscle fiber.
|
Slow oxidative muscle fibers |
Fast oxidative muscle fibers |
|
Slow oxidative muscle fibers are responsible for using aerobic metabolism to provide low power contraction and relaxation over a longer period. |
Fast oxidative muscle fiber uses aerobic metabolism to produce ATP and higher contraction than slow oxidative muscle fiber. |
|
They hydrolyze ATP slowly. |
They hydrolyze ATP fastly. |
|
The slow oxidative muscle fiber is responsible for longer periods without causing fatigue and stabilizing bones and joints. |
Fast oxidative muscles are principally responsible for providing walking movement that required energy. |
