Optoelectronic measures in the analysis of running target shooting.
In this study, we examined the construct validity and practical significance of an optoelectronic shooting training system (Noptel ST 2000 Sport) for the technical analysis of running target shooting. A total of 37 male shooters of three different skill levels participated in the study. Principal component analysis revealed four common factors of 16 variables describing the aiming trajectory of the rifle barrel: (i) Holding area, (ii) Accuracy of aiming, (iii) Cleanness of triggering and (iv) Time on target. These factors were suggested to describe the essential components of running target shooting. According to the discriminant analysis, the shooters of various skill levels seemed to discriminate successfully into three groups when the aiming trajectory data were analysed. Finally, the aiming trajectory variables represented a 43% of the total variance in the shooting score. In summary, the present data indicated that the optoelectronic shooting training system had practical significance and supported the technical analysis of rifle barrel movement in running target shooting. A sub-set of variables, which reflect the essential information of running target shooting performance, were outlined for training and coaching purposes.
