Definitions:

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.

Concentric Contraction

Muscle contraction where muscle fibers shorten while generating force, typically occurring when a muscle is actively producing movement.
