The large number of articles, opinions, journals, and experts in fitness and muscle building is the area of lifting weights more like the practice of medicine in the 16 Century seem like a concrete science. Every day, new theories, approaches, and wonders training seem to contradict each other and announce that they have the truth, and that following their advice you will realize the body of your dreams. Apparently some of them on the right track, others do not, but asto tell the difference between all? The answer lies in understanding the basics of the biological process of muscle growth. Once you know some of the most important principles, you will be better able to judge whether an exercise routine is based on physical principles of sound, or completely false.
The basic principle is to understand that your muscles adapt, what they are exposed to stress. If you spend all day on the couch, then you will have a fine of musclesequipped for Couch. If you run 40 minutes each day, as the body will adapt to it. If you follow the same number of sets and reps and weight lifting routine, then your body adjusts, too. And even if you adjust your system will stop growing, and easy to reach this new level of peace, to have the minimum required to operate at this level. Therefore, the basic idea is that if you want growth, you constantly need to overload the system.
TheBy progressively overloading the muscles is called muscle hypertrophy, and this is the increase in muscle mass and cross section. Note that the number of muscle cells (a process called hyperplasia muscle) has increased but the increase in size. As you work your muscles to microtrauma, where small cracks appear in the muscle tissue exposed. These tears signals to activate what is called "satellite cells on the surface of the muscles and increaseand the damage sites, where they are going to fuse with existing muscle fibers, helps them to regenerate.
While the satellite cells multiply and fuse with the damaged areas, your immune system comes into play a complex sequence of reactions that led to the inflammation is to contain and repair damage and clear the area of waste products. This process, if not the only key to the health of the muscle, but the growth hormones and cytokines that are released as manystimulate muscle hypertrophy. Among these hormones such as insulin-like growth factor (IGF), fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) are. Growth hormone (GH) is also published, and is the key to promoting the proliferation of satellite cells and the release of IGF.
What is important to understand is that the whole process (micro-trauma, where the complex interaction of satellite cells, the immune system, growth factors and hormones) depends not only exercise, but alsoGetting the right amount of rest and nutrition to optimize the healing process. Muscle hypertrophy occurs when the muscle heals, not when you train. In addition, the muscles will adapt only what they need, leading to an effect of "plateau", but things change and challenge them in new ways. So it's a good idea to turn your exercise routine, as it is to do P90X, and always to your body guessing what's next.
