Definitions:

Muscle Contractions

The process by which muscle fibers shorten and generate tension in response to a stimulus, producing movement or maintaining posture.

Isometric

Pertaining to the contraction of a muscle without significant change in length, typically involved in exercises where the joint angle and muscle length do not change.

Isotonic

Referring to a solution that has the same salt concentration as the cells and blood of the body, or to muscle contractions where muscle length changes under a constant load.

Muscle Fibers

Muscle fibers are the individual contractile units within skeletal muscle, consisting of myofibrils that enable muscles to contract and generate movement.
