儿童少年脑电发育特点与速度素质关系的研究 However, alpha wave became dominant in the occipital region from 6 to 16 years old. （4）The speed of both boys and girls aged between 6 and 12 years with age increasing, the boy at the age of 12 after speed continues to improve, but the pace of girls at a standstill. Boy speed of natural growth for 6-15 years old, girl for 6 to 12 years old; Boys speed sensitive period for 6-10 and 12-14 years old, female speed sensitive period for 6 to 9 years old. （5）Aged 6 to 12, the correlation coefficient betweenα2% and 50 meters that from all children, High speed and Low speed childen is -0.51,-0.64 and -0.52 respectively. In addition, the correlation coefficient between θ/β and 50 meters that from all children, High speed and Low speed childen is 0.51, 0.71 and 0.52 respectively. Conclusion: The brain development of normal children has obvious age span , it has rapid growth and 6-10 years old for speed is the best period of development.The speed of normal children could be predicted , according to the alpha 2 relative power and theta/beta ratio,howere,the development of the nervous system has little impact to the teenagers.
