Biomechanics of highly precise movements: the aiming process in air rifle shooting.

Abstract

The position of the aiming line of the rifle in relation to the target center and fluctuations of the rifle were recorded with the specially designed optoelectronic device and 'Selspot' system respectively. It was found that while aiming, qualified shooters apply a 'fixation' strategy. With an increase in skill level, a decrease in general fluctuations at the rifle as well as random aiming error have been found. The decrease of aiming point fluctuation is partially achieved by compensating rifle movements relative to various degrees of freedom.
