Bodybuilding Guide – The Science Behind Muscle Growth

Bodybuilding Guide – The Science Behind Muscle Growth

The shortest bodybuilding guide in history on this subject could be as simple as this… Lifting weights damages muscle tissue on a microscopic level (not to be confused with a muscle tear injury). Proper nutrition, predominantly but not only protein, provides the materials to rebuild the muscle. Rest gives your body time to repair the damaged muscle fibers. The result is bigger and better regrowth. But what’s the science behind muscle growth?

Weight lifting routines – The routine of stretching and contracting muscle under weighted loads, damages the tissue of the muscle under the stress of the load. Myosin and Actin are filamentous proteins found in the cells and fibers of your muscle. These proteins suffer micro tears, resulting in the soreness you feel the next day. A microscopic tear is a long way away from an injury, so be careful, but don’t worry (consult your doctor before undertaking any weight lifting programs).

The soreness that you experience the next day could be viewed as your body reminding you to give it time to rebuild. The rebuilding process starts within minutes of the micro tears occurring, but can take days to complete. This process is called Hypertrophy. Your muscle fibers react to the damage by rebuilding themselves with additional Myosin and Actin, resulting in muscle growth.

Of course any bodybuilding guide will tell you, rest and sleep is a big part of muscle recovery and growth. However, the body also needs the best muscle building supplement combinations and weight training diet. It takes energy to perform weight lifting routines, but your body also needs energy to grow, even when you are sleeping. That energy comes in the form of calories, so a proper weight training diet is crucial. The amount of additional Myosin and Actin generated in the rebuilding process is directly linked to the volume of muscle growth. Myosin and Actin need Amino acids. Amino acids are effectively the building blocks of protein, so consuming enough is vital. Around 1 gram per pound of bodyweight daily is widely thought to be enough.
