| This is a model of what a mTOR pathway protein looks like. |
When you break down muscle exercising, it is always beneficial to ingest protein after your workout to rebuild the muscles you have just broken down. Proteins serve as a muscle building molecule. They are composed of polymers of amino acids joined together by peptide bonds. The question is what kind of protein is the best for building muscle and rejuvenating the muscle you break down while exercising. The answer has been found with a natural way of fasting and exercising that activates a growth hormone muscle rejuvenation and a BCAA amino acid that is the most abundant out of the three amino acids. The latest science has found out that a special type of protein called mTOR holds the key to muscle building, and Leucine is the most abundant BCAA out there and helps your muscle growth speed up tremendously. Leucine and mTOR are also intertwined together and work together to help build muscle.
The protien mTOR stands for mammalian target of rapamycin. "When mTOR is activated, it causes muscle cells to increase protein synthesis. This leads to skeletal muscle hypertrophy. mTOR integrates cellular information regarding intracellular nutrient status and energy and oxidative stress levels.When it deems that energy levels are high and the muscle cells are stressed, it activates in order to help the cells heal and rebuild in a stronger manner." (http://www.naturalnews.com/033957_muscle_growth_proteins.html) There are two extremely effective ways to activate mTOR activity are to ingest branch-chain amino acids, these amino acids will make your muscles to recover quicker and includes mTOR within them; another way to activate mTOR is to exercise intensely while fasting. It's very critical to exercise intensively after you fasted because this raises your natural testosterone and gives you an anabolic drive. You can actually produce a natural type of human growth hormone by doing this. When you exercise intensively you should exercise for about five to thirty minutes of non stop moving such as sprinting and exercises that keep you moving and raise your heart rate.
People who exercise daily always think about what they can do to have muscle growth. The best way to achieve muscle growth is to directly intake protein after exercising. Taking BCAA's are also an essential way of rebuilding the muscle that you have broken down. There are three main BCAA's; isoleucine, valine, and leucine. The most abundant amino acid of the three is leucine. Leucine is an amino acid that helps stimulate protein synthesis. It also helps turn on the switch within your body to start the process of rebuilding muscle. Leucine is not naturally produced in your body, so we need to take this amino acid to further our muscle growth through dietary supplements such as BCAA's. Leucine is one of the main amino acids that activates mTOR which starts the process of building muscle back up to recover. mTOR starts the production of muscle rejuvenation and leucine is the main activator as I mentioned in the second paragraph about BCAA's being an effective way to activate mTOR. These two protein building molecules are essential to know when you are weight lifting or even just exercising by playing sports and such, because after you perform in such activities you need to start your recovery process to build the muscles you break down.
