目的 :采用脑成像技术监测心理学任务过程中脑激活模式的变化来反映有氧运动对执行功能的影响 ,并结合认知行为表现来评价有氧运动对执行功能所产生的训练效益.方法 :通过行为测量和近红外光谱功能成像(fNIRS )的方法探讨10 min中等强度自行车蹬踏运动对15名老年人在 Flanker任务过程中的行为表现和脑激活模式的影响.结果 :运动任务的 Flanker效应的反应时显著低于对照任务[ t(1 ,14) = -2 .64 ,P< 0 .05 ].在左侧额极区(L-FPA )上 ,运动任务的 Flanker效应的 oxy-Hb信号显著高于对照任务[ t(1 ,14) = 3 .94 ,P<0 .001 ].结论 :10 min中等强度有氧负荷显著提高了老年人 Flanker任务的行为操作表现 ,并增强了左侧额极区(L-FPA )的神经活性 ,且局部脑区神经活性的增加与认知表现的提高同步出现.

Objective :Brain imaging technique was used to monitor the changes of the brain acti-vation patterns in the process of psychological task to reflect the effect of the aerobic exercise on the executive function and to evaluate the training effect of the aerobic exercise on the per-formance of the executive function .Methods :The behavior and brain activation patterns of 15 elderly people with 10min moderate intensity cycling were discussed by means of behavioral measurement and near infrared spectroscopy (fNIRS ) .Results :The Flanker interference of re-action time (RT ) of the experiment group was significant lower than the control group (t(1 ,14)= -2 .64 ,P< 0 .05) .The flanker interference of oxy-Hb single of experiment group was sig-nificant higher than the control group in left frontopolar area (L-FPA ) ( t(1 ,14) = 3 .94 ,P<0 .001) ,Conclusions :10min moderate intensity aerobic load can significantly improve the opera-tion behaviors of the elderly flanker task ,and enhance the neural activity in the left frontal pole (L-FPA ) and the improvement of local regions of the brain neural activity increased with cog-nitive performance synchronization occurs .
