Muscle is a unique body organ that is specialized in transforming chemical energy into a movement. While in the formation of the muscle itself or muscle hypertrophy becomes popular and very concerned once by the fitness and bodybuilders start from the contraction process to the moment where the muscle needs proper recovery through the nutrition program. In the meantime, check this option to get more good info about muscle building.
You need to know, to cause or realize the size of the optimal muscle and large muscle contraction needs to be done that can be quite significant. Here is the mechanism of muscle formation to form large quickly:
Contraction or contraction is the ability of the muscle to shorten from its original size, initiated by the action potential in the muscle fibers that causes the release of calcium ions from the sarcoplasmic reticulum causing an event of motion contraction reaction. In the mechanism, any muscle movement produced by the body will start in contraction. This is the first step the progress of muscle formation becomes big.
According to the results of the study with electron microscopy and X-ray diffraction found by Hansen and Huxly (1955), put forward a finding of the theory of muscle contraction called model sliding filaments. This theory suggests that contractions are based on two sets of filaments in contractile muscle cells, which are actin filaments and myosin filaments. The stimulus received by acetylcholine causes actomyosin to contract (contraction).
While contracting, the muscles produce the movement as well as the appropriate lifting power desired. The heavier the load is played, the greater the tear of the muscle cell tissue that will fo, rm into large. Not only that, as long as there is a potential action of the nerves and calcium ions to be released, the contractions will continue. But once the nerve action potential starts to feel tired and the release of the ion is no longer released, the muscle will rest in its original position, and this is called relaxation or muscle retraction.
Clearly, in one full movement (repetition) the muscle will undergo two phases of movement, first called contraction or shortening of the muscle, and the second is called muscle retraction or phase of muscle recovery or elongation of muscle in its original condition.
