Comparing three methods for measuring the movement of the bow in the aiming phase of Olympic archery

AbstractThe aim of this study was to compare different methods for assessing the bow movement in the aiming phase of Olympic archery. Therefore an optoelectronic system (NOP), a 3D- (V3D), and a 2D-video based system (V2D) were used to simultaneously measure the bow movement in 12 shots of three archers. The results showed intraindividual good agreement in the vertical component of the aiming trajectory between NOP and V3D (resp. V2D), and in horizontal component between NOP and V3D, whereas there is less agreement between NOP (resp. V3D) and V2D, thus indicating specificity in the method used
