【摘要】：目的:脑电图主要反应中枢神经系统的发育情况,而神经系统的发育是速度素质的基础。本论文旨在研究正常青少年儿童随年龄增长的脑电发育特征,分析其与速度发展的关系,以期找到利用脑电图特征来预测速度的可能方法。方法:研究对象为四川省广元市620名6-16岁中小学生,采用Nation9128W数字化脑电图仪测试其安静闭目清醒状态下脑电图,分析各导联绝对和相对功率,并同时测试其50m跑成绩。结果:(1)6-16岁儿童少年脑电各频段相对功率具有显著的年龄差异。随年龄增长,δ、θ、α1波相对功率减少,α2和β波相对功率均增加,并且6-11岁和13-15岁是α2波的快速增长期。(2)男生速度素质的自然增长期为6-15岁,女生为6-12岁;男生速度敏感期为6-10岁和12-14岁,女生速度敏感期为6-9岁。(3)高速度素质儿童的50m成绩与α2%的相关系数为-0.64,而与θ/β比值的相关系数为0.71。结论:儿童少年脑发育具有明显的年龄阶段特征,具有快速增长期,6-10岁为速度素质发展的最佳时期。其中α2相对功率和θ/β比值是儿童速度素质发展的参考指标之一。
[Abstract]:Objective: EEG mainly reflects the development of central nervous system, and the development of nervous system is the basis of speed quality. The purpose of this paper is to study the characteristics of EEG development with age in normal adolescents and to analyze the relationship between EEG and speed development in order to find a possible method to predict the speed by using EEG characteristics. Methods: 620 primary and middle school students aged 6 to 16 years old in Guangyuan City, Sichuan Province, were studied. The EEG was measured by Nation9128W digital EEG instrument, and the absolute and relative power of each lead was analyzed. The results of 50 m running were also tested. Results: (1) there was significant age difference in the relative power of EEG in 6-16 years old children and adolescents. With age, the relative power of 未, 胃, 伪 1 wave decreased, and the relative power of 伪 2 and 尾 wave increased, and the rapid growth period of 伪 2 wave was 6-11 years and 13-15 years old. (2) the natural growth period of speed quality of boys was 6-15 years old, and that of girls was 6-12 years old. The speed sensitive period of boys was 6-10 years and 12-14 years old, while that of girls was 6-9 years old. (3) the correlation coefficient between 50 m achievement and 伪 2% of children with high speed quality was -0.64, and the correlation coefficient with 胃 / 尾 ratio was 0.71. Conclusion: the brain development of children and adolescents has obvious characteristics of age and stage, and it is the best time for the development of speed quality in the period of rapid growth from 6 to 10 years old. Among them, 伪 2 relative power and 胃 / 尾 ratio are one of the reference indexes for the development of children's speed quality.
