muscle growth

[mehdi71000]

Hi
What is responsible for muscle growth? Like after exercise what triggers the cells to produce more muscle cells. What chemicals?
Thanks

That's not settled. Right now, the leading hypothesis is that exercise damages the cells, which grow while repairing. I don't know how much experimental support the idea has.

When you get into the fringes of sports and nutritional science, there's a lot of "information," but not a lot of reliable research.

Skeletal muscle cell do not typically reproduce i.e. divide. The number of muscle cells do not increase however they do increase in size. There are some that indicate that they may even split but not as in mitosis. Damaged cells do repair and "over repair" thus causing an increase in muscle size. Muscle size is also inhanced by increased contracture. Hypoxic conditions in the muscle cells increase lactic acid which also stimulates the increased production of human growth hormone (HGH). The Japanese have introduced a new type of quick workout which involves the use of constriction bands on muscles to restrict blood flow and shorten the time needed to reach an anaerobic muscle environment and increase lactic acid production. Fewer reps and fewer sets are needed to tire (damage) the muscle. Have not tried it and probably won't.

To repair damaged muscle tissue takes time, amino acids and energy. You must eat right and this is why one should not work the same muscle hard every day. A day of rest allows for repair and prevents over training.

Big muscles are found in the weight room, hideing under the big weights. You have to pick up a lot of the big weights to find them.
