Abstract
An aim of work is research and ground of major criteria of estimation of individual tеhnikо-phizicheskоya preparedness of jumpers in length of junior and senior youth age.
 Material and methods. In researches took part 24 young athletes-jumpers in length, that in 2016/2017 training participated in the competitions of championship of the Kharkov area on track-and-field among youths of middle and senior age. Registration of biomechanics descriptions of technique of broad jumps was conducted by means of the speed videosurvey treated in the computer program of videoanalysis of «Kinovea», and also indexes of the электронно-оптической system, «Start-finish» and «Optical path». Research motion. The individual features of young sportsmen are analysed in relation to diagnostics of 13-и of the most meaningful kinematics descriptions of technique of broad jumps and results of their competition activity. The statistical analysis of degree of influence of different parameters of motions is conducted on their sporting result.
 Results. The models of multiple linear regression are made between the sporting results of young sportsmen 14-17 and by the kinematics parameters of individual technique of jumpers. For the estimation of statistical authenticity of model the coefficient of determination (R2) is used. The estimation of statistical meaningfulness of model coefficients showed that two from eleven coefficients can be considered different from a zero (meaningful). It is coefficients at factors «corner of flight of GCMB» and «pathlength of passing of GCMB in the moment of pushing» away.
 Conclusions. Models, rendering larger influences, are distinguished on a sporting result. Attempt of mathematical ground of criterion of rational organization of motions (СROM) of jumper is executed in length in the process of pushing away was made. The estimation of efficiency of СROM of jumper for certain is confirmed long ways of moving of GCMB of sportsman in the process of pushing away.
