前言一般运动水平的儿童少年(尤其是小学低年级学生)的短跑途中跑,基本上体现出一种自然技术;具有一定运动水平的短跑运动员则体现出一种竞技技术。国内外优秀短跑运动员的途中跑技术的形成,是一个经过长期系统训练的过程,这个过程实质上也就是自然技术向竞技技术演变的过程。因此,中小学生掌握短跑途中跑技术的正确与否,对将来在较高阶段能否进一步巩固与提高跑的技术影响很大;但 Preface The general movement level of children and adolescents (especially the lower primary school students) sprint on the run, basically reflects a natural technology; have a certain level of athletic sprinter is reflected in a competitive technique. The formation of en route running skills of excellent sprinters at home and abroad is a process of long-term systematic training. This process is essentially the evolution of natural technology to competitive technology. Therefore, whether primary and secondary students master the correctness of the technique of running on the middle of the sprint will have a great influence on the technology that can be further consolidated and improved at a later stage. However,
