摘　　要：目的:基于注意网络测试范式探讨不同级别青少年拳击运动员各注意子网络的差异。方法:选取黑龙江体工队拳击健将运动员十人,吉林体育学院二级运动员十人,对这二十名拳击运动员进行注意网络测试,在进行行为学测试的同时运用功能性近红外光谱技术监测运动员各脑区的血氧变化情况。结果:行为学结果显示健将运动员与二级运动员注意网络中警觉网络和执行控制网络效应具有显著性差异(P<0.05);影像学结果表示在警觉网络中,两组运动员在rIPL处血氧激活量具有显著性(P<0.05);在定向网络中血氧激活量在rIGF处差异显著(P<0.05);执行控制网络中血氧激活量在rIPL(P<0.01)和rDLPFC(P<0.05)处差异显著。结论:拳击运动员的级别越高,警觉网络效应和执行控制网络效应越强;背外侧前额叶激活区域越大,运动员的执行控制功能越强。Objective:To explore the differences of attention subnetworks in the juvenile boxers of different levels based on attention network test paradigm.Methods:10 master athletes from Heilongjiang sports team and 10 second grade athletes from jilin sport university were selected by experimental method.The attention network test was carried out on the 20 boxers,and functional near-infrared spectroscopy was used to detect the changes of blood oxygen in each brain region of the athletes.Results:The behavioral results showed that there were significant differences in the alertness network effect and executive control network between the master athletes and the second grade athletes(P<0.05).FNIRS results showed that there was a significant level of blood oxygen activation at RIPL in both groups of athletes in the alert network(P<0.05);In the targeted network,the activation of blood oxygen was significantly different at RIGF(P<0.05);The amount of blood oxygen activation in the executive control network differed significantly in RIPL(P<0.01)and rDLPFC(P<0.05).Conclusion:(1)The higher the ranking of the boxer,the stronger the alert network effect and executive control network;(2)The larger the activation area in the dorsolateral prefrontal lobe,the stronger the athletes’executive control function.
