Abstract

Gun training with official weapons is one of the most important training activities in the police. The aim of this paper is to determine the relations and define the prediction model between the accuracy and precision of pistol shooting, as a specific motoric task, and the maximum muscular strength of the hand grip, as a basic indicator of general physical hand preparation. The sample covered a total of 46 subjects: students of the Faculty of Sport and Physical Education who selected the subject Shooting within the study program (N = 19, 11 male students and 8 female students), active Ministry of the Interior officers (N = 6), competitors in practical shooting, IPSC (N = 4), recreational shooters (N = 10, 8 men and 2 women), and beginners (N = 7) who have only passed one hour of basic training in firearms. For the measurement of the maximal muscle force of the hand finger flexor, a standardized test - 'grip of the hand' was used while the shooting was carried out from the CZ 99 handgun, using the precision shot method from a distance of 6 meters. Criterion variables were: accuracy and precision of shooting, while the predictive variables were the maximum forces of the left and right hand, as well as a summary indicator of the achieved maximum force level of both hands. Based on the obtained results, it can be concluded that the accuracy of shooting statistically correlates with the following variables: inversely proportional to the accuracy (r = -0.889, p = 0.000) and proportional to all variables of the maximum force of hand grip, as measures of the strength of the upper extremities ( Fmax_R, Fmax_L and Fmax_SUM at r = 0.437, p = 0.002, r = 0.439, p = 0.002 ir = 0.443, p = 0.002, respectively). In relation to the accuracy of the shooting, a statistically significant but inversely proportional correlation with all variables of the maximum force of the hand grip were determined (Fmax_R, Fmax_L and Fmax_SUM at r = -0.356, p = 0.015, r = -0.375, p = 0.010 ir = -0.369, p = 0.012, respectively). In general, based on the obtained results of this study, it can be concluded that the maximum force of the hand grip, as an indicator of arm strength, is statistically significant, and at the level of influence of 19.3% positively influences the accuracy, i.e. with 13.4% positively affects the accuracy of the shooting from the CZ 99 official handgun in a precision shooting situation from a distance of 6 meters.
