Secrets That Make Muscles Grow Big

PARIS - More and more work, the muscle can grow bigger. Today, a new study reveals the secrets that make lifting weights can increase muscle.

Reported by LiveScience, Wednesday (04/01/2012), the secret lies in the chemical factors produced by muscle cells at work (for example when lifting weights), which instructs the muscle stem cells to overcome the load by means multiply. This compound, serum response factor (SRF) seems to trigger the muscle stem cells to grow niak and into muscle fibers. This means that enlargement of the muscle as a whole, and more energy.

"This finding is not unexpected and quite interesting. Signals from muscle fibers to control the behavior and participation of stem cells in muscle growth," said Sotiropoulos Athanassia Iserm of medical research institutions, in France.

Using mice that are designed to have a shortage of SRF in muscle, the researchers found that without these factors, overloaded muscle will not enlarge itself.

SRF sends a signal through the network of genes, including one called COX2. Sotiropoulos also said that the anti-infective drugs are like a blunt ibuprofent (COX2), has the possibility to inhibit muscle growth.
