With good cause, branched-chain amino acids in supplements have experienced a return in the bodybuilders & fitness communities. BCAAs have more science backing them up than most other supplements on the market.
when BCAA supplementation can help you grow skeletal muscle (the kind that makes you swole), it is especially beneficial for preserving bulk when on a calorie-restricted diet. They’re very important for bodybuilders who want to get their bodies as lean as possible.
Although dieting helps you look great onstage, at the beach, and in front of your friends, it can also reduce your muscle mass.
Diets are catabolic, which means they can cause muscle breakdown for a variety of reasons. The more thin a body becomes, the more likely it is to lose skeletal muscle as the body works harder and harder to retain body fat stores. As a result, the body will turn to muscle to meet its energy needs. This is bad news for anyone looking for a hard body.
Muscle loss happens at the molecular level when the body promotes protein breakdown (catabolism) to liberate muscle amino acids for metabolic fuel. As if this weren’t terrible enough, muscle loss is exacerbated by the fact that levels of muscle protein synthesis will also fall as a result of decreased caloric intake.
Muscle mass is calculated as Muscle mass = rate of protein synthesis – rate of protein breakdown.
When the rate of synthesis equals the rate of breakdown, no muscle is gained or lost. Muscle growth occurs when the rate of synthesis exceeds the rate of breakdown. When the rate of breakdown exceeds the rate of synthesis, muscle is lost. When you diet, you may be burning the candle at both ends, increasing muscle breakdown while decreasing protein production.
Exercise amplifies the metabolic consequences of dieting. You can become more lethargic as you lose weight. Training sessions are difficult due to decreased calorie intake and glycogen storage. If you’re too weary or weak to lift as much weight as your body is used to, your muscles will adjust and require less energy to complete the activity.
As a result, you will not gain skeletal muscle, and your body may use the lean muscle you do have for energy because you are not using it to lift a high load.
How BCAAs Aid Muscle Preservation
Here are some of the ways branched-chain amino acids powder can help you stay slim while dieting.
Branched-chain amino acids (the necessary amino acids valine, isoleucine, and leucine) increase muscle protein synthesis, potentially more than a typical protein on its own. Protein synthesis, often known as gains, is the metabolic process through which your body creates new muscle protein.
Reduce Protein Degradation
Increased BCAA levels also benefit you by slowing the rate of protein breakdown. They accomplish this by lowering the activity of the protein breakdown pathway as well as the expression of various protein breakdown complexes. (They reduce the amount of mRNA produced by the gene encoding these components.)
When we return to our original equation for muscle mass, it’s clear that boosting synthesis and decreasing breakdown will result in muscular increase or maintenance.
Have Better Workouts
Amino acid supplements may also help you obtain a more intense workout. Branched-chain amino acids compete with the amino acid tryptophan for entry into the brain, where tryptophan is transformed to the neurotransmitter serotonin.
Serotonin levels rise during exercise, making you feel tired and unable to push as hard.
bcaa powder reduces the quantity of tryptophan that crosses the blood-brain barrier, lowering the amount of serotonin generated. This may enable you to work harder, for longer periods of time, and achieve greater results.
