Protein and Amino Acid Supplementation in Athletes Throughout the ages, the popularity of increasing protein intake among the athletes has flourished which is believed to provide strength, endurance, and speed enhancement. An effect of supplementation is reviewed. AA improved athletic performance, improved vigor and earlier recovery from fatigue. Among the essential AA that was given high focus among the athletes are leucine, isoleucine, and valine collectively referred to as the branched-chain amino acids or BCAAs commonly given as supplementation to athletes? Studies found that during exercise, there is an increased breaking down of protein to meet the increasing energy needs of the skeletal muscles. With prolonged exercise, BCAAs in the blood decline promoting tryptophan uptake across the blood–brain barrier increasing serotonin formation in brain causing sedative effect thus an athlete feels central fatigue. It is suggested that AA supplementation increases athlete’s endurance as the protein breakdown and BCAAs decline during exercise are slowed
