Quadriceps femoris muscle is the thigh muscle that extends the leg by acting on the knee joint. The origin and insertion of the muscle move closer together and the muscle becomes fatter. Eccentric contractions also create the most metabolic stress on a muscle, which in turn results in the release of more hormones such as growth hormones, in order to stimulate the body for protein synthesis. Simulations demonstrate that a muscle model based on the winding filament hypothesis can predict residual force enhancement on the descending limb of the length-tension curve in muscles during eccentric contraction. Types of muscle contraction: Isotonic concentric contraction leads to muscle shortening, isotonic eccentric contraction leads to muscle lengthening. An example is bending the elbow from straight to fully flexed, causing a concentric contraction of the Biceps Brachii.
