摘　　要：本文利用８０ 年代初发展起来的描述大脑功能变化的新技术——脑电地形图，对运动员杠铃蹲起负荷前、后的脑电功率值进行了对比分析。结果发现，负荷后即刻与安静状态相比，δ、θ频段的功率值增加，α３ 频段则减少。说明该运动负荷后大脑皮层神经细胞出现抑制过程，表明较长时间的。The article takes advantage of a new technology developed in early 80's for describing the changes of brain function to compare and analyze the EEG power before and after barbell squatting rising with load. The result shows that the power of 8.0 frequency band increased and the power of a 3 frequency band decreased after exercise immediately comparing with those at rest. Inhibitory process emerged in nervous cells of cerebral cortex after exercise. Physical training of longer time and definite intensity may affect central nervous system (for example: cerebral cortex).
