Abstract
This study presents the frequency analysis of a rifles vibrations involuntary generated by the muscles of an aiming shooter. The vertical acceleration of the end of the pneumatic rifle barrel was analysed. The nature of vibrations was determined by means of power spectrum density function, obtained by averaging estimators of spectrum density for subsequentt aimings. The existence of two characteristic resonance areas was found - adjacent to 4.5 Hz and to 13.5 Hz. An attempt was undertaken tto combine some of the parameters of the vibrations with the result achieved by the shooter under the conditions of a simulated competition. Verf.-Referat
