INSTRUMENTATION AND MEASUREMENT METHODS APPLIED TO BIOMECHANICAL ANALYSIS AND EVALUATION OF POSTURAL STABILITY IN SHOOTING SPORTS

Abstract

The main problem of sport technique in precision sports consists in maintaining the body segments as stable as possible in position and orientation. Experimental data in shooting sports proved that the posture that shooters adopt is mechanically unstable as consequence of the interactions among the body segments. In this way shooters and archers try to make their posture more consistent and reproducible reducing the variability of their actions during the aiming and shooting. The object of this study is to present the basic consideration respect to biomechanical analysis and evaluation of postural stability in shooting sports. The proposed theoretical model and the designed measurement chain composed of a sonic digitizer, a force plate and an EMG system seems to be an efficient tool in order to describe and evaluate postural stability.
