Definitions:

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.

Muscle Tension

Describes the state of partial contraction in a muscle, even when it is not actively being used, helping to maintain posture and readiness for action.

Contraction

The process of muscle fibers shortening in response to stimulation, resulting in movement or tension in the muscle.
