摘要: 研究羊肉中L-肉碱抗疲劳作用机理。将昆明种小鼠分组,分别进行平行实验和交叉实验测定抗疲劳功能,观察L-肉碱对实验小鼠游泳时间、身体指数、血清生理生化指标、腿部肌肉L-肉碱含量和脂肪酸片断的影响。结果表明:L-肉碱可以有效延长实验小鼠平均游泳时间,减轻体重及腹部脂肪量,显著降低血清中甘油三酯及总胆固醇的水平、乳酸及尿素氮含量;液相色谱显示小鼠体内L-肉碱含量与游泳时间有显著的相关性。L-肉碱有显著的抗疲劳作用,通过脂肪代谢参与供能。

Abstract: The antifatigue effects of L-carnitine from mutton were determined by parallel and crossover experiments respectively. The effects on swimming time,body index,physiological and biochemistrical indices in serum,contents of L-carnitine and fragments of fatty acid in leg muscle was observed. The results showed that L-carnitine can prolong the average swimming time,decrease the body weight and abdomen fat weight,and decrease the contents of CHO,TC,urea nitrogen and lactic acid in serum. The content of L-carnitine is significantly related to the swimming time by results of HPLC. L-carnitine hsa significant antifatigue effect and can supply energy by participate in fatty acid metabolism.
