β-Alanine is one of the more popular sport supplements used by strength/power athletes today. The popularity of β-alanine stems from its ability to enhance intracellular muscle-buffering capacity thereby delaying fatigue during high-intensity exercise by increasing muscle carnosine content. Recent evidence also suggests that elevated carnosine levels may enhance cognitive performance and increase resiliency to stress. These benefits are thought to result from carnosine's potential role as an antioxidant. This review will discuss these new findings including recent investigations examining β-alanine supplementation and increased resiliency to posttraumatic stress and mild traumatic brain injury. This review will focus on the physiology of carnosine, the effect of β-alanine ingestion on carnosine elevations, and the potential ergogenic benefits it has for competitive and tactical athletes.
β-丙氨酸是当今力量/爆发力运动员使用的较受欢迎的运动补剂之一。β-丙氨酸之所以受欢迎，是因为它能够增强细胞内肌肉缓冲能力，从而通过增加肌肉肌肽含量来延缓高强度运动期间的疲劳。最近的证据还表明，肌肽水平升高可能会提高认知能力，并增强抗压能力。这些益处被认为是由于肌肽作为抗氧化剂的潜在作用。本综述将讨论这些新发现，包括最近关于补充β-丙氨酸以及增强对创伤后应激和轻度创伤性脑损伤的恢复能力的研究。本综述将重点关注肌肽的生理学、摄入β-丙氨酸对肌肽升高的影响，以及它对竞技和战术运动员潜在的促力益处。
