Aiming point trajectory as an assessment parameter of shooting performance

Abstract

PurposeThe purpose of this study was to elaborate on the scientific methodology for providing an assessment of air-pistol shooters’ aiming stability by (i) substantiating the parameters of aiming stability, (ii) specifying the quantitative evaluation methods in using an optoelectronic target, (iii) evaluating the reliability of tests determining aiming stability, and (iv) developing a methodology for creating individual and group parameters of aiming stability.MethodsThe aiming trajectories of 95 airpistol shooters, each of whom fired 60 shots using a SCATT optoelectronic simulator, were calculated to develop individual and group aiming stability parameters. Research methods included an optoelectronic registration of movement, research on top air-pistol shooters’ sports results, mathematical modelling, variation statistics, cluster analysis, two-way ANOVA with data correlation and reliability theory tests.ResultsIt was found that an average aiming point trajectory on the SCATT optoelectronic target measured one second before a shot could be accepted as an assessment parameter of aiming stability, as it is one of the basic parameters of technical preparation and its position is not influenced by the ballistic characteristics of the pistol and pellets (ŋ = 0.944).ConclusionsThe parameters of aiming stability in air-pistol shooting were developed using a modification of the clustering method. This allows for the identification of weak points in the structure and organization of shooters’ training and for adjustment of the training process.

Accuracy of SCATT optoelectronic shooting system

“…7 It is the analysis of actual aiming point coordinates and the distance from the centre of the target that coaches and athletes use to make the appropriate corrections in the technique of the shot execution. 13 Therefore, an important factor that influences the analysis of the efficiency of the shot execution and the ways of its correction, if necessary, is the correspondence between the registration results of the aiming point on the SCATT target and its real position. 14–16 The research has determined presence of errors in defining the aiming point coordinates in SCATT optoelectronic system.…”

“…This simulator can determine important technique parameters: vibration amplitude of the weapons in the final phase of aiming, velocity of the aim projection line on the target and the time of aiming. 13 These indicators help coaches to choose the novice, to determine the level of specific qualities development (static endurance and stability of the ‘shooter-gun’ system), to monitor changes in the technique of shooting exercises by comparing the values obtained during conventional and competitive condition trainings and to control the athlete’s body reaction to the training loads and so on.…”

Smart textile device for shooter’s fingers movement monitoring

“…manufacture device that could be attached to real pistol (Beretta 92 or Glock) to measure displacement of the trigger [8]. Another example is finger pressure force measurement device, included in the SCATT shooting training kit [9,10]. Researchers often relied on the sensors, mounted on the trigger [4,11] while assessing trigger pull movement.…”

Estudio de las variables de equilibrio, fuerza y antropometría determinantes del rendimiento en tiro olímpico en la modalidad de pistola aire

“…Según Zanevskyy et al (2012) los programas de entrenamiento deberían estar diseñados a largo plazo con el fin de evitar el sobreentrenamiento, su consecuente fatiga y el deterioro del rendimiento en el tiro de pistola.…”

“…La estabilidad del arma parece ser un factor íntimamente relacionado con el rendimiento deportivo en el tiro olímpico (Baca y Kornfeind, 2010;Chung et al, 2004;Chung et al, 2006;Hawkins, 2011;Konttinen et al, 1998a;Konttinen et al, 2000;Mononen et al, 2007;Pellegrini y Schena, 2005;Scholz et al, 2000;Tang et al, 2008;Vaez-Mousavi et al, 2008;Zanevskyy et al, 2012), teniendo los tiradores más experimentados patrones más estables en la ejecución que sus contrincantes noveles o menos experimentados (Baca y Kornfeind, 2010;Pojman et al, 2009). …”
