目的 观察经过8周集训后进行3 km限时匀速跑的武警新兵身体功能状况改变情况。方法 从武警某部新兵营随机抽取15名男性新兵作为测试对象，在跑步机上完成3 km限时匀速跑，分别测试运动前后肛温、心率、SpO₂、心电图、脑血流图的变化。结果 （1）运动后即刻肛温为（38.1±0.4）℃,较安静时升高0.9 ℃，但仍属于生理安全范围；（2）运动后即刻心率为（145±27.6）次/min，较安静时升高65次/min，提示属于中等运动强度；（3）运动后即刻SpO₂为97.0%±1.4%，较安静时稍有下降，但停止运动后迅速恢复并超过运动前状态，提示运动负荷强度适宜；（4）运动后窦性心动过缓和窦性心律不齐现象消失，P-R间期缩短的发生较运动前有所增多，均属于生理现象；（5）运动后绝大多数受测颅内动脉的平均血流速度均明显增快，差异有统计学意义（P＜0.05），而平均搏动指数有所下降，提示受试者的脑血管弹性较好，运动负荷强度适宜。结论 经过8周集训的武警新兵参加3 km限时匀速跑后身体功能状况良好。由于存在个体差异，军事训练中应加强科学组训和医务监督。

Objective To measure the somatic function of recruits of Chinese People’s Armed Police Forces after military training. Methods In March 2009，fifteen male recruits who underwent 8 weeks, military training were enrolled in this study randomly. The rectal temperature, heart rate, SpO₂, electrocardiogram, and rheoencephalogram were measured before and after 3 km running on a treadmill. Results （1）the rectal temperature at once after running was (38.1±0.4) ℃ on average；（2） the heart rate at once after running was (145±27.6) b/min on average；（3） the SpO₂ at once after running was (97.0±1.4) % on average；（4）the sinus bradycardia and the sinus arrhythmia all disappeared at once after running；（5）the average blood flow velocity rose and the pulsated index decreased. The hemodynamics of brain was regular. Conclusions The recruits of Chinese People’s Armed Police Forces after 8 weeks, military training have obtained a fine somatic function. Because of the individual difference in the recruits, scientific training and medical supervision is important.
