新兵军事训练中骨骼肌细胞损伤的研究

Skeletal Muscle Injuries of Recruits in Military Training

目的调查军事训练中骨骼肌肉损伤情况。方法应用肌酸激酶(creatine kinase,CK)和肌红蛋白(myoglobin,Mb)评估肌肉损伤,对563名新兵进行了血清电解质、CK、肌酸激酶同功酶(creatine kinase isoenzyme-MB,CKMB)、Mb和肌钙蛋白Ⅰ(cardiac troponinⅠ,cTnⅠ)检测。结果军事训练后CK和Mb明显升高,而cTnⅠ均正常。高CK值者血清钾、钠和镁含量低,而血清磷含量高。且体质量指数与血清CK含量呈正相关。结论军事训练可引起骨骼肌细胞损伤,低钾、低镁和超重是军事训练引起骨骼肌细胞损伤的高危因素。

Objective To investigate the incidence of skeletal muscle injuries of recruits in military training.Methods Serum creatine kinase （CK）, creatine kinase isoenzyme-MB （CK-MB） and myoglobin （Mb） were used to assess the skeletal muscles injuries of recruits in military training.A total of 563 recruits were randomly selected.The changes in ser- um electrolyte, CK, CK-MB,Mb） and cardiac troponin I （cTnI） were measured.Results After military training the ser- um CK,CK MB and Mb were significantly increased （P （0.01）, but cTn! was not elevated. The kalemia, natrium and magnesemia were significantly decreased, but phosphonium were significantly increased in high serum CK servicemen, and the body mass index was positively related with serum CK.Conclusion Military training may hring skeletal muscle inju- ries.The hypomagnesemia,hyponatremia,hyDokalemia and overweight are the risk factors.
