Inter- and Intra-Individual Analysis in Elite Sport: Pistol Shooting

Abstract

Research into the relationship between body sway, aim-point fluctuation, and performance in pistol shooting has been inconclusive. The present study reex-amined this relationship on an interindividual basis, as done in previous studies, and via intraindividual analysis, not previously examined. Five elite pistol shooters performed 20 shots similar to competition conditions. For each shot, body-sway parameters and aim-point fluctuation parameters were quantified for the time period 1 s to shot. An AMTI LG6-4 force plate was used to measure body-sway parameters, while a SCATT shooting analysis system was used to measure aim-point fluctuation and shooting performance. Multiple regression analysis indicated that body sway was related to performance for one shooter, aim-point fluctuation was related to performance for three shooters, and body sway was related to aim-point fluctuation for four shooters. These relationships were specific to the individual, with the strength of association and parameters of importance being different for different shooters. However, interindividual analysis indicated that only aim-point fluctuation was related to performance. It was concluded that body sway, aim-point fluctuation, and performance are important in elite level pistol shooting, and performance errors at the elite level are individual-specific. Individual analysis should be a priority when examining elite level sports performance.

Physical and physiological attributes of soccer goalkeepers - Should we rely only on means and standard deviations?

“…For example, in a recent study on female volleyball players (Nikolaidis et al, 2012), it was observed that large individual variability existed in most of the physical characteristics (e.g., body mass and height) and physiological attributes (e.g., aerobic capacity and anaerobic power) measured among the players, as well as that the intra-individual variability was observed in all age groups classified in this study (under 14, 14-18, and over 18 years of age). Intra-individual variability was also discussed in studies on elite pistol shooting performers (Ball et al, 2003) and elite golfers (Hassmen et al, 2004).…”

Друго истраживање истих аутора (Ball, Best, & Wrigley, 2003a) поново је испитало ове од-носе на интериндивидуалној основи, као што је урађено у претходним студијама и преко интра-индивидуалне анализе која раније није испитива-на.
