【摘要】：以南方籍新兵为受试对象 ,观察冷习服对机体氨基酸代谢的影响。结果表明 ,冷习服前后各种必需氨基酸摄取量均在正常标准之上 ,超出供给量的 5～ 10倍。只有蛋氨酸的摄取量 ,冷习服后较冷习服前有所减低 ,但仍在正常范围之内。摄入热能在正常范围。经过一个月的耐寒锻炼取得冷习服 ,血清支链氨基酸明显变化 ,除甘氨酸、结氨酸、精氨酸、丝氨酸、胱氨酸 (Gly、Ser、Cys)明显减少 ,除蛋氨酸 (Met)外其他支链氨基酸均有明显增高。血清亮氨酸、异亮氨酸、丙氨酸、苏氨酸 (Leu、Ile、Ala、Thr、Val、Arg、Pro)水平在冷习服后均有明显的升高 (P0 0 5 ) ,说明冷习服后氨基酸的代谢有明显增强。目前部队的膳食结构和组成有助于加速冷习服的建立
[Abstract]:The effects of cold acclimation on amino acid metabolism were observed. The results show that the intake of essential amino acids before and after cold acclimation is above the normal standard, which is 5 ~ 10 times of the supply. Only methionine intake was lower after cold acclimation than that before cold acclimation, but still within normal range. Heat intake is in the normal range. After one month of cold acclimation, serum branched-chain amino acids were significantly changed, except glycine, desaminic acid, arginine, serine, cystine Glycine serine and cystine glycosine. All the branched amino acids except methionine (Met) were significantly increased. The serum leucine, isoleucine, alanine and threonine leucine IleAla-Ala-Thrr-Val-Arg Pros increased significantly after cold acclimation (P 0.05), which indicated that the metabolism of amino acids was obviously enhanced after cold acclimation (P < 0.05). The serum leucine, isoleucine, alanine and threonine leucine were significantly increased. The current dietary structure and composition of the army can help speed up the establishment of cold acclimatization
