Title:
Stability of alignment during extended hold times in the aiming phase of elite archers
Authors:

Abstract:
The purpose of this study was to investigate the differences in the stability of alignment in elite archers when hold times in the aiming phase are increased. Eight elite archers (age = 21 ± 2.3 year, height = 1.79 ± .13m, mass = 78.35 ± 7.27kg) took part in the study (two females and six males). Participants shot six arrows under three separate conditions: 100%, 200% and 300% of average hold times in the aiming phase. The velocities of the key anatomical landmarks of alignment (LRSP, LLHE, LAP, RAP, RMHE, RRSP) were measured under all conditions and arrow score was recorded as a measure of performance. One-way repeated measures analysis of variance (ANOVA) and bonferroni post-hoc statistical analysis were adopted for kinematic variables. Friedman’s test of differences betweem repeated measures and Wilcoxen signed-rank test were adopted for arrow score. It was found that velocities at five of the six kinematic variables increased significantly as HT increased (LRSP: p < .001, LLHE: p = .022, LAP: p <.001, RMHE: p = .001, RRSP: p < .001). Arrow scores decreased significantly as HT increased (p = .02). It was concluded that increasing HTs during the aiming phase decreases the stability of alignment and subsequently reduces arrow score.
