摘要：

目前运动训练时大脑皮质激活模式还未得到完全阐明。试验招募了8名健康受试者，指导其应用弹性杆进行肩部振动运动和肩部屈曲-伸展的简单运动，应用功能近红外光谱测量大脑4个感兴趣区域中的氧合血红蛋白值，对比两种运动的大脑皮质激活模式。在肩部振动运动与肩部简单运动过程中，可观察到初级感觉运动皮质、前运动皮质、运动辅助区、前额叶皮质激活。两种运动训练过程中，初级感觉运动皮质手臂定位投射的氧合血红蛋白值相近，但较其他感兴趣区更高。相反，肩部振动运动时受试者初级感觉运动皮质腿和躯干定位投射的氧合血红蛋白值明显高于肩部简单运动时。说明两种运动均可使与肩部运动相关的大脑皮质运动区域激活，特别是在初级感觉运动皮质手臂定位投射中；同时，肩部振动运动对初级感觉运动皮质腿和躯干定位投射有额外的激活作用。

Abstract:

To date, the cortical effect of exercise has not been fully elucidated. Using the functional near infrared spectroscopy, we attempted to compare the cortical effect between shoulder vibration exercise and shoulder simple exercise. Eight healthy subjects were recruited for this study. Two different exercise tasks (shoulder vibration exercise using the flexible pole and shoulder simple exercise) were performed using a block paradigm. We measured the values of oxygenated hemoglobin in the four regions of interest: the primary sensory-motor cortex (SM1 total, arm somatotopy, and leg and trunk somatotopy), the premotor cortex, the supplementary motor area, and the prefrontal cortex. During shoulder vibration exercise and shoulder simple exercise, cortical activation was observed in SM1 (total, arm somatotopy, and leg and trunk somatotopy), premotor cortex, supplementary motor area, and prefrontal cortex. Higher oxygenated hemoglobin values were also observed in the areas of arm somatotopy of SM1 compared with those of other regions of interest. However, no significant difference in the arm somatotopy of SM1 was observed between the two exercises. By contrast, in the leg and trunk somatotopy of SM1, shoulder vibration exercise led to a significantly higher oxy-hemoglobin value than shoulder simple exercise. These two exercises may result in cortical activation effects for the motor areas relevant to the shoulder exercise, especially in the arm somatotopy of SM1. However, shoulder vibration exercise has an additional cortical activation effect for the leg and trunk somatotopy of SM1.
