Definition and Science:
Amino acids are the chemical units, or “building blocks” that make up human muscle tissue. Protein quality is measured by the amount of the specific amino’s within it.
The 22 amino acids are the molecular building blocks of proteins. 9 are referred to as essential, meaning that they must be supplied from some food or supplement source, and the others, which are known as non-essential, or more correctly, dispensable or conditionally indispensable, are based on the body's ability to synthesize them from other amino acids.
L-leucine, L-isoleucine and L-valine are the most important group of amino acids for athletes. Around 33% of muscle protein consists of BCAA’s. Even moderate exercise causes levels of BCAA’s to drop rapidly which results in muscle tissue breakdown (catabolism), fatigue, and a drop in testosterone levels.
Benefits to you:
Amino acids are essential to the human body and athletes can especially benefit from supplementing amino acids because they aid in repair, growth, and development of muscle tissue. The body, through assimilation of amino acids, produces over 50,000 proteins and over 15,000 enzymes. Amino acids are not only responsible for the production of all the body's enzymes (including digestive enzymes), but they also play a key role in normalizing moods, concentration, aggression, attention, sleep, and sex drive. After protein is consumed, it is broken down into amino acids. Then, individual amino acids are used to create necessary body proteins and enzymes. Digestive enzymes break down the proteins a person consumes into amino acids.
The benefits are broken down below....
Maximizes lean muscle growth
Optimises post-workout recovery
Maintenance of cells
Maintenance of tissues
Helps avoid muscle degeneration
When To Take:
Personally the best time to take BCAA's are basically anytime your body is in a catabolic state. This is mainly first thing on a morning when you've fasted for around 8 hours. Also immediately after training when your body is in a very catabolic state. Basically comsuming BCAA's at this time changes your body's state from a state of catabalism to a state of anabalism.
Why Not Use Just Whey?:
The simple answer is....BCAA's are readily broken down (from protein molecules) so they can be absorbed into the bloodtsream immediately.
Dosage:
Only around 3-5grams are required per serving. In capsule form this translates to between 6-10 capsules. Personally i like mega dose BCAA's.
Final Thoughts:
I'd say BCAA's are a must for any athlete. They are very cheap (around £15 for 500 capsules). They prevent muscle breakdown which is basically your main goal when wanting to build lean muscle. Other protein based foods and supplements do this aswell but they need to be broken down first so your body would spend more time in a catabolic state (which is bad). Below i've explained (basically) the process of protein digestion. Hopefully this will give you a clear view of why BCAA's are important.....
When consumed, protein takes the form of very complex molecules arranged in chains of amino acids. So the bonds binding these complex molecules together must first be broken down. This digestive process begins in the stomach (unlike starch, which begins in the mouth), where hydrochloric acid attacks the protein molecules separating them and breaking them down into amino acids. Once this has happened the gastric enzyme pepsin starts to digest the amino acids.
BCCA's bypass the initial digestion stage which enables muscle repair to begin much quicker than it would do without supplementation.
