摘　　要：目的:观察冷习服训练对新兵甲襞微循环和血浆NO含量的影响,旨在为进一步探讨冷习服机理和训练方法提供依据。方法:从驻寒区某部新兵中随机抽取50名,分为2组,各25名,对照组按部队正常操课,试验组按制定的冷习服训练计划进行训练。分别于训练前、训练30d后对两组新兵的甲襞微循环和血清NO含量进行检测比较。结果:试验组训练后与训练前比较,甲襞微血管管袢长度、输入支管径、输出支管径、袢顶直径均明显增大,血流状态、红细胞聚集分值和总积分值均显著减小(P<0.01),微血管管袢形态积分和流态积分显著降低(P<0.05),血浆NO含量显著升高(P<0.01);对照组训练后血液流态积分、血流状态和红细胞聚集分值显著低于训练前(P<0.05),血浆NO含量显著升高(P<0.05),其他指标未见明显变化(P>0.05);两组训练后比较,试验组甲襞微血管形态、血流状态指标和微循环各项积分值均显著优于对照组(P<0.05),血浆NO含量高于对照组,有显著性差异(P<0.05)。结论:局部冷刺激配合延长户外锻炼时间,可以促进人体甲襞微循环对寒冷产生良好的适应性,冷习服训练后甲襞微循环状态的改善可能与血浆NO含量升高有关。Objective： To explore the effects of cold acclimatization training on nail fold microcirculation and plasma NO in recruits. Methods： Fifty new recruits in cold regions were divided randomly into two groups. Control group did normal training, the experimental group did cold acclimatization training.The changes of nail fold microcirculation and plasma NO were detected respectively before training and 30 days after training.Results：The length of loops, the input vessel diameter, the output vessel diameter and the loop top diameter in training group were notably larger（P〈0.01）, the integral nail fold microcirculation morphology and flow pattern were lower （P〈 0.05）, plasma NO were larger （P 〈0.01 ）, but blood stream state, erythrocyte aggregation score and total score was lower than those in control group（P〈0.01）. The integral flow pattern, blood stream state, erythrocyte aggregation score in control group after training was lower,plasma NO was higher than those before training （P〈0.05）,whileother parameters showed no significant differences. The capillary configuration, blood flow regime and each individual value of the experimental group was significantly better than those in the control group after training, plasma NO was higher than control group （P 〈0.05）. Conclusion ： Through the local cooling combined with outdoor exercise time prolonging, nail fold microcirculation will have a good compatible change to the cold. The improvement of nail fold microcirculation status may be positively correlated with the increase of plasma NO.
