| 运动可引起体内能源物质的消耗并导致内环境的改变，合理使用营养补充剂可以维持生物体内的环境稳态，对高水平运动员竞技成绩的提高起着非常重要的作用。β-丙氨酸是目前受到国内外广泛关注的一种运动营养补剂，作为机体内合成肌肽的限速前体，补充后可增加骨骼肌内肌肽含量，从而增加肌肉对无氧酵解过程中H+堆积的缓冲能力，延缓运动疲劳，提高人体的运动能力和运动表现。本文综述了β-丙氨酸作为运动营养补充剂在人体内的代谢过程及其对不同类型运动影响效果的研究进展，并针对β-丙氨酸的剂量应用、补充方法、不良反应等进行了总结，为该营养补剂在运动领域的应用提供一定的理论依据。 |
| 英文摘要: |
| Exercise can cause the consumption of energy substrates inside the body and lead to changes in the body's internal environment. Rational use of nutritional supplements can maintain the environmental stability inside the living organism. It also plays an important role in improving the sports performance of high-level athletes. β-alanine is a kind of sports nutrition supplement that draws extensive attention at home and abroad. As a rate-limiting precursor of synthetic carnosine in the body, β-alanine can increase the content of carnosine in skeletal muscle. As a result, it increases muscle's ability of buffering H+ accumulation during anaerobic glycolysis, delays sports fatigue, and improves athletes' sports ability and sports performance. This paper reviews the research progress of the effects of β-alanine as a sports nutrition supplement on body's metabolic process as well as specific sports. This paper also summarizes the dose application, compensation process, and untoward effect of β-alanine, providing a theoretical basis for the application of this nutritional supplement in the field of sports. |
