The purpose of this paper was to study the age features of formation of kinematics of high-speed run of boys and girls of younger and average school age in conditions of the traditional organization of lessons of physical culture. On the basis of the Moscow school №710 a six-year longitude experiment was carried out. During the experiment the kinematic parameters of high-speed run (SR) of pupils from II-VII classes were studied in conditions of application of traditional techniques of perfection of movement (TM) at the lessons of physical culture. During the age development of kinematics of the SR children and teenagers have alternation of the periods of stabilization, improvement and deterioration of the components of engineering of movement. In the conditions of application of the TM of 7-8 year-old girls and boys (II form) the stabilization, and in the age of 8-9 years (III form) - the deterioration of engineering of the SR are observed. The period of significant perfection of the components of engineering of the SR (the sensitive period) of boys is marked from 10 till 13 years (V-VII forms), and it attacks girls one year earlier - from 9 years. The perfection of cyclic locomotions of pupils of a younger and an average school age is an independent process which directly does not depend on the development of motor abilities.
