Rectification of the Definition and Classification about Speed Quality
The importance of speed as a critical component of physical quality is widely recognised at both practical and theoretical levels.However,the definitions and extensions of speed quality still need to be uniformly defined in vari-ous studies..Based on this,the research on the concept of speed quality conducted at domestic and international level is reviewed,and formal logic and other theories are used to classify and analyse the definition and division of the con-cept,and to point out its main fallacies.On this basis,the definition and division of speed quality is refined with the help of the existing body of knowledge.The study concluded that ①in terms of definition,speed quality refers to the human's ability to exercise within a unit of time;②in terms of division,on the first level,speed quality can be divided into reaction speed quality and action speed quality according to the different physiological bases.On the second level,reaction speed qualities can be divided into simple and complex reaction speed qualities according to the type of re-sponse signal;action speed qualities can be divided into uniform and variable speed qualities according to the state of human movement.On the third level,according to the direction of acceleration of human movement as the standard,the variable speed quality can be divided into acceleration quality and deceleration quality.
