Effect of Cold Adaptation on Metabolism of Amino Acid

The effect of cold adaptation on metabolism of amino acid was studied among the new male soldiers coming from the southern China in this paper.The results indicate that before and after the cold adaptation,all essential amino acid were taken in normal level,all but methionine were more 5~10 times than that of given.A bsorbed caloricity was at normal level.After cold adaptation was obtained,by one month cold training,the offshoot amino acid were changed obviously in the serum,Gly,Ser and Cys were decreased distinctly,all other offshoot amino acid except Met were increased evidently.The level of Leu,Ile,Ala Val,Arg,Pro and Thr were raised obviously after cold adaptation in the serum(P<0.05).These results showed that after cold adaptation,the metabolism of amino acid was enhanced evidently.Presently,the military meals are helpful to adapt cold.
