茶氨酸是茶叶中含有的一种具有多种生理功能的特殊氨基酸.目前,人们对茶氨酸的生理功能研究主要集中于降血压、抑制肿瘤、松弛神经和提高学习记忆力等方面,而对缓解运动性疲劳功能的研究相对较少.阐述了茶氨酸延缓运动性疲劳功能及其机理研究,提出由于茶氨酸具有多种生理活性,以茶氨酸为主体的保健食品、运动饮料或运动营养品将具有广阔的开发前景.“,”Theanine, an amino acid found specifically in tea, has multiple physiological functions. At prestent, much researches have been focused on lowering blood pressure,inhibiting tumor,relaxing and improving memory, etc., but relatively little researches were focused on the alleviating exercise-induced fatigue.The effects of theanine on delaying exercise-induced fatigue and the latest research progresses of its mechanism were expounded.It was pointed out that because theanine has many bioactivities, health food, sports drinks and nutrition containing theanine will have broad prospects.
