Because branched-chain amino acids are obtained externally and cannot be made by your body, many opt for BCAA supple- ments to improve their body’s overall function and the quality of their workouts. These supplements can be especially ben- eficial for athletes just starting out and struggling with workout endurance issues. Of course, the benefits that we’ve already mentioned are re- ally only the tip of the iceberg. The fact is there are many other reasons why you should consider adding a BCAA supplement to your day. What are they? We’ll detail nine of the top reasons why you should consider supplementing with BCAAs. 1. Boost Performance And Prevent Fatigue During Exercise One of the most popular uses for BCAAs is preventing fatigue during exercise. BCAAs can be especially powerful and useful when an athlete is just starting out. With that said, the reality is that exercise fatigue can strike anyone. One study published in The Journal of Nutrition found that BCAA supplementation improved athletes’ perceived exertion and mental fatigue after a 30-kilometer race. Researchers also found that it im- proved participants’ performance on a cognitive test taken after the race. Some even experienced an improvement in physical performance. 2. Promote Muscle Protein Synthesis For fitness junkies, one of the greatest benefits a supplement can offer is muscle protein synthesis. Not only does research published in the American Journal of Physiology indicate that BCAA supplementation prevents the degradation of muscles – the importance of which we’ll get into a bit later – but, accord- ing to Swedish researchers, it also produces anabolic effects on people in the post workout recovery period. Protein synthesis is everything if you want to build muscke. ironmanmagazine.com | SEPTEMBER 2017 53
