hypertrophy

Through training, the muscles that work against a challenging work loadprogressively to increase muscle mass and cross-sectional area, referred to ashypertrophy. But why one muscle cells can grow and how it developed? Musclehypertrophy can be defined as the growth and increase the size of muscle cells. In general, most of the muscle hypertrophy occurs as a result of physical exercise,like lifting weights. When a person starts exercising, the nerve will send impulses to muscles to make the process of contraction. This will result in significantchanges in muscle size. In a continuous training, there is a complex interaction of the nervous system resulting in an increase in protein synthesis and muscle cellsbegan to grow bigger and stronger. Skeletal muscle has two basic functions ofthe contracts to cause movement of the body and relax to provide stability forbody posture. Each skeletal muscle must be able to contract and relax to make amotion. Progressive overload is one way of applying pressure levels vary andintermittently for skeletal muscle, in order to adjust the level of muscle tension.Muscle can be adapted to increase the size and number of proteins, consisting ofmuscle fibers miofibril in each, leading to an increase in the size of individualmuscle fibers and employment requirements for daily work.
