What is an eccentric muscle contraction

Khangar says it is lengthening under load, controlling the force of gravity.An eccentric contraction is the motion of a muscle while it is lengthening under load, where the muscle contracts to control joint motion performed by an outside force.During eccentric contraction, the muscle lengthens as the resistance becomes greater than the force the muscle is producing.The simplest example of an eccentric contraction is lowering a barbell in a biceps curl.Due to its specific physiological and mechanical properties, there is an increasing interest in employing eccentric muscle work for rehabilitation and clinical purposes.Negative work is the force used to reverse a muscle from its initial trajectory.

Eccentric contraction refers to muscle action in which the muscle force yields to the imposed load.This is the most popular type of muscle contraction.Muscles, especially the heart, also use free fatty acids as fuel.An example of an eccentric contraction is when performing an exercise such as a biceps curl.A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens.An eccentric muscle contraction is called negative work.

Very simply, during muscle contraction, a change in muscle length is caused by the thin filaments being pulled along the thick filaments.Two situations can lead to an eccentric movement from this point;.
