BIOMECHANICAL MEANS OF THE OPTIMIZATION OF POSTURE AT THE SHOOTING WITH THE PISTOL

Abstract

INTRODUCTION - Different kinds of additional burdening; heavy jackets, belts etc. have traditionally being used during the training of shooters. The practice shows, however, that the efficiency of their usage is not high as they distort natural human biomechanical structure of strength inter-relations with medium. As an alternative to it we have used during the trainings of athletes the hypergravitational costume which makes it possible to increase both the module of strength interrelations of athlete's and the support, preserving natural geometry of his body masses as well as kinematics of movements. [Laputin A.N., 19811. RESULTS - The results of biomechanical experiments show that the total time of taking sight decreases, the amplitude of big and small vibrations of pistol and general centre of mass increases and also the rate-rhythmic structure of shot changes for the shooters being traditionally burdened with different loads. The truth of changes is proved by calculation values of Student's criterion (3.26)' which exceeds the limit value (2.06) for selection of volume 30 of elements and reliability P4 0.95.
