Study Notes
Muscle Contraction and Force Generation
- The rate at which a muscle works is defined as the power of muscle contraction.
Types of Muscle Contraction
- Involuntary contraction is responsible for smooth muscle.
- Voluntary contraction is responsible for skeletal muscle.
Factors Affecting Muscle Contraction
- The main factor affecting the force and velocity generation of muscle is the load on the muscle.
- The anatomical factor that affects the force production of normal muscle is the length of the muscle fiber.
Speed of Muscle Contraction
- The speed of contraction for skeletal muscle is fast.
- The speed of contraction for smooth muscle is slow.
