This review provides a critical evaluation of the metabolic rationale for the use of individual amino acids as nutritional ergogenic (work-generating) aids in athletes. The conclusion is that in contrast to the claims made on sport nutrition products, branched-chain amino acids do not improve endurance performance, that the evidence that glutamine supplements may improve immune function is rather weak, and that the available commercial supplements contain too little arginine to increase growth hormone levels. No studies have been performed to investigate the claim that tyrosine supplements can improve explosive exercise.
本综述对将个别氨基酸用作运动员营养强化（提高运动能力）辅助剂的代谢原理进行了批判性评估。结论是，与运动营养产品所宣称的相反，支链氨基酸并不能提高耐力表现，谷氨酰胺补充剂可能改善免疫功能的证据相当薄弱，而且市面上现有的补充剂中精氨酸含量过低，无法提高生长激素水平。目前尚无研究对酪氨酸补充剂可改善爆发力运动这一说法进行调查。
