Definitions:

Eccentric Tension

A type of muscle contraction where the muscle elongates while under tension, often engaged during the lowering phase of a lift.

Isotonic Contraction

A type of muscle contraction in which the muscle changes length while the tension remains constant, typically involved in lifting and moving objects.

Isometric Contraction

Muscle contraction that occurs without changes in muscle length, resulting in tension without movement.

Concentric Tension

Refers to the force generated by muscle fibers shortening during contraction, often used in the context of exercise and muscle physiology.
