运动生理学研究证明,少年儿童(即:初中一、二年级、小学高年级学生)大脑皮层兴奋快,神经过程灵活性强,反应敏捷。因此,好动是他们的最大特点。如果这时对他们进行科学的、系统的、真正能调动他们活动兴趣的有关短跑速率训练,不仅能有效地提高他们的短跑速率,而且对于他们健康的 Exercise physiology studies have shown that young children (ie: junior high school sophomore, primary high school students) excited cortex fast, flexible nerve processes, quick response. Therefore, active is their most important feature. If at this time, the relevant sprint rate training that subjects them to science, the system, and the real interest in mobilizing their activities will not only be able to effectively increase their dash rate but also be beneficial to their health
