Method for Estimation of Quality Sports of Technique Diagnostics of Technical Mistakes

Abstract

In the present paper criteria of efficient running technique at a maximal speed have been determined. The authors assume as efficient the technique which provides the same performance by less mechanical energy cost. The purpose of the study is to answer the question about how to run (what kinematic, dynamic and energy characteristics should be) to provide an efficient running technique. To investigate the efficiency of technique two methods -one of regression residuals and the other of discriminative features, are widely used. Regression residuals method [2] allows to differentiate between athletes «good at technique» and athletes «no good at technique». The merit of the method lies in the absence of motor potential influence on technique assessment. However the method does not provide technique criteria, i.e. biomechanical characteristics of the motion necessary for higher performance at the same motor potential level. The discriminative features method [1] allows to determine technique criteria by their comparison in highly-and low-qualified athletes with the same motor potential. The authors suggest combination of the above methods for technique criteria determination. That will enhance their merits and eliminate drawbacks. At first, using the regression residuals method the subjects have been divided into groups of athletes good at technique and athletes no good at technique. Then the discriminative features method has been used, i.e. biomechanical motion characteristics have been compared in the groups of athletes good and no good at technique. Those characteristics that differ significantly in both groups have been taken for technique criteria, criteria choice being independent on athletes' motor potential.
