the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
The mechanical force of muscle contraction is generated by a sliding of thin filaments past thick ones.
the amount of ATP in the muscle cells
Eccentric contraction (isotonic)
The most common form of muscle force production is the concentric contraction force.
Muscle force is the force produced by the contraction of a muscle. Force vectors, torque vectors, and difference vectors can all be used to help describe this force.
This is muscle flexion or isotonic contraction.
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
A muscle contraction happens when too much force or stress is forced upon a muscle cavity. Dr. Whitmore PHD
If the muscle can not shorten because the muscle is trying to move a load that is greater than the force, then the contraction is isometric.
During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
Concentric muscle contraction will shorten a muscle and decrease the angle between two bones. This type of contraction involves the muscle generating force as it shortens to move a body part.
