国内外对田径项目的研究大都集中在专项力量、专项耐力、专项技术的分析。本文通过文献资料法、逻辑法和系统分析法,对专项速度概念进行了定义和划分,在对速度、专项速度的结构进行系统分析的基础上,根据百米专项速度的特点,构建了百米专项速度的理论体系。为教练员系统认识和剖析田径各项目专项速度结构提供了具体可行的理论依据,有利于教练员进行科学的训练,为我国其它体育项目专项速度理论构建开启思路,提供参考与借鉴。 At home and abroad, the research on track and field projects mostly focuses on the analysis of special forces, special endurance and special technologies. This paper defines and divides the concept of special speed through literature, logic and system analysis. Based on the systematic analysis of the structure of speed and special speed, according to the characteristics of the special speed of 100 meters, a hundred meters Special speed of the theoretical system. It provides a concrete and feasible theoretical basis for the coaches system to recognize and analyze the special speed structure of each item of track and field, which is good for coaches to carry out scientific training and opens up ideas for the construction of special speed theory of other sports in our country.
