In a world that breathes competition, athletes keep their guards up, knowing that a small tip off may cost them consequences as worse as losing muscles. Every performance that is good enough is never enough; they have to give it their best for mediocrity has no match against excellence. In every competition, optimal performance is expected. Branch chain amino acids (BCAA), leucine, isoleucine and valine are essential amino acids are considered as ergogenic aid for sports enthusiast to maximize performance during extreme athletic trainings.
Branch chain amino acids (BCAA) leads to prolong exercise during heat stress in both men and women, says study finds. To determine the efficacy of BCAA supplementation on performance endurance, two trials consisting of six women and seven men were subjected in exercise to exhaustion and rest in heat. The conclusion of the study that appeared in Medicine & Science in Sports & Exercise pointed out that the time from cycling to exhaustion was increased in both sexes and that supplementation with BCAA resulted in prolong moderate exercises.
Moreover, numerous studies lead to conclusions that amino acids affect metabolic pathways which may improve exercise performance in athletes. Take for example a recent research by Sharp et al 2010 which studied the effect of BCAA during a short period of high-intensity training. The subjects that consumed 6 grams of BCAA per day lead the researchers to suggest that sport supplementation high in BCAA leads to an improved anabolic hormonal profile.
Furthermore, a study by Blomstrand, E. 2001, suggested that by way of supplementation with BCAA, ratings of perceived exertion and mental fatigue can be lowered down, thereby improving cognitive performance in lengthened periods of exercise. The researcher even concluded that enhancement in physical performance during competitive exercises was observed in athletes taking the supplement. This influence on exercise and training was explained by central fatigue hypothesis which showcases a mechanism contributing to the development of fatigue in prolonged exercise periods. The proposition predicts that upon consumption of BCAA, concentration of BCAA in the plasma increases which in turn reduces the movements of free tryptophan in the brain, consequently leading to reduced levels of serotonin in the brains. Lower concentrations of serotonin have been associated to assuage symptoms of fatigue, thus, improving endurance and promoting longer physical and physical stamina in athletes.
Perhaps one of the most widely celebrated subject of research regarding BCAA's is its actual consequence on the overall performance of athletes, whether it improve outcomes or not have been the focus of scrutiny in the previous years. Although, a number of researches are needed for reevaluation of the relationship between BCAA levels and athletic performance, supplementation has been found out to decrease muscle damage markers usually common during intense trainings. To evaluate this, Koba et.al, 2007 conducted a research to determine whether amino acid supplementation with BCAA improves running performance. The researchers from Japan concluded that maintenance of BCAA concentration through supp lementation in long distance run reduces LDH level and reduces muscle damage in this athletes contributing to an overall positive effect in their performance. To confirm this, another trial conducted in Japan demonstrated that supplementation of amino acid mixture during athletic training will most likely result to an improvement in the oxygen-carrying capacity of blood and reduction of endogenous muscle breakdown post-exercise.
Branch chain amino acids (BCAA) connotes the possibility of an advancement in any sports endeavor mainly by acting on the central fatigue system, allowing athletes to experience higher pace during prolonged period of extreme exercise and by reducing muscle breakdown and muscle soreness to allow for a faster a recovery. BCAA's are not organically produced in the body and must be supplemented through our diet, since sports enthusiasts' needed additional protein requirement, supplementation with BCAA is likewise recommended.
