目的：研究运动训练对本体感觉的影响,探讨本体感觉特点对控制人体的精细化动作的作用,以期揭示本体感觉产生的脑机制。方法：用恒定刺激法测量重量差别阈限作为衡量本体感觉能力的标准,研究不同人群本体感觉的差异;用Pearson相关分析本体感觉与射击成绩的关系;Oddball范式下研究本体感觉差异影响的脑电成分与特征。结果：体育专业大学生和武警战士的重量差别阈限小于软件学院大学生;本体感觉与手枪部位靶射击成绩、机枪射击成绩呈显著性相关（P〈0.05）;体觉差异对脑电成分N100、P180和N250的影响非常显著（P〈0.01）,尤其是N100和N250;对晚期成分P300没有显著性影响（F=1.657;P=0.199）,P300对刺激类型非常敏感。结论：运动训练可以提高本体感觉能力,本体感觉能力的提高能够改善运动成绩,尤其是一些要求精准的运动项目。N100和N250成分可以作为评定本体感觉能力的指标,本体感觉刺激的神经输入和运动神经命令的输出能够解释本体感觉刺激产生的机制。

Objective：For researching the effects of exercise training on proprioception,invetigating the effects of proprioception characteristics on fine motion of the body,in order to reveal the brain mechanism of proprioception.Methods：Weight difference threshold is measured using the method of constant stimulus,which is used as the evaluation standard of proprioception ability.Forthermore,we use Pearson correlation analysis to study the relationship between proprioception and shooting performance,and under Oddball paradigm to research the effects of proprioceptive differences on brain electrical components and signature.Results：The weight difference threshold of physical education majors and armed police soldiers is less than software colleges.The correlation between proprioception and pistol and machine gun shooting performance is significant（P＆lt;0.05）.Somatosensory differences on proprioceptive event related potential（PERP）N100,P180and N250is very significant（P＆lt;0.01）,especially on N100and N250.There was no significant effect on the late components of P300（F=1.657;P = 0.199）,P300is very sensitive to stimulus type.Conclusion：Exercise training can improve proprioception,then,which can improve athletic performance from different aspects,especially some of the requirements of accurate project.The N100and N250components can be used to evaluate the proprioceptive ability.The output of motor command and input of proprioceptive stimulation from sensory nerve can explain the mechanism of proprioceptive.
