新兵运动后肌钙蛋白Ⅰ、心钠素、血管紧张素Ⅱ的变化

The changes of cTnⅠ、ANP and ATⅡ in military recruits after the routine running

[目的]通过对天津地区某部新兵在3 km运动前后的心肌肌钙蛋白(cTnI)、心钠素(ANP)、血管紧张素Ⅱ(ATⅡ)水平的检测,了解运动对新兵心肌有无损伤及某些内分泌激素水平的影响。[方法]选取240名18-20岁男性战士,分别测定3 km运动前后cTnl、ANP、ATⅡ水平。[结果]新兵运动前cTnI均正常范围,运动即刻cTnI升高阳性率为40%,运动后4 h升高的阳性率为14.1％;血浆ANF水平于运动后即刻、运动后4h较运动前明显升高,ATⅡ水平于运动后即刻升高(P<0.01)。[结论]新兵3 km运动后有部分出现一过性肌钙蛋白升高,但这样的运动强度不会对心肌细胞造成严重损伤。血浆ANF、ATⅡ水平的升高,使机体的应激反应能力增强,说明目前的运动强度可使新兵获得较佳训练效果。

[Objective] This study was sought to evaluate the current training program in military recruits by examining the changes of cTnⅠANP and ATⅡ after running. [Methods] 240 males, aged from 18-20 years military recruits in Northern China was oberseved in this study. The level of blood plasma cTnⅠ、ANP and AT Ⅱ was measured before and after routine 3-km running. [Results] The level of serum cTnⅠ was normal before exercise, It has increased by 40% immediately and by 14.1% 4 h after exercise. Serum level of AT Ⅱ has raised immediately after running, Serum level of ANP after exercise was obviously higher than baseline. [Conclusion] This study indicates that 3-km routine running does no harm to myocardium of military recruits, as well as moderate the stress response of the heart induced by exercise.
