The purpose of this study was to assess the effects of biomechanical selected parameters of penalty corner drag flick for accuracy. The best drag flicker of A.M.U. Aligarh, Hockey team has been selected for this study. His age, height, weight was 19yrs, 180.50cm and 65kg respectively. The subject used his own stick approved by the All India Association Committee, India. He took 10 trials of drag flick from stationary ball to hit given target (1 X 1feet) hung on the right corner of the goal post. The two Canon Legria SF-10, 8.1 video cameras were used. The film was recorded on sunny and clear weather at Astroturf Hockey Field during evening training session. For the 3D co-ordinates 18 body landmarks were used to reconstruct the 3D motion using standard DLT procedures. The digitized 3D data were collected from two phase (1) Contact phase and (2) Release phase. The Knee flexion angle was considered for the front foot only. Max TRAQ 3D motion analysis software was used to calculate the selected parameters and statistical analysis was accepted using SPSSv.16, mean, standard deviations and correlation was used to find out the relationship of selected variables of the study with ball velocity. The alpha level of significance was set at p<0.05 for all statistical tests. The result was found that significant relationship exist ball velocity with HSB at both phases, EA at contact phase, EV at contact phase and KA at release. Where as insignificant relationship exist ball velocity with ES, PS SA, PA, SV, PV and KV at both phases and KA at contact phase and EA and EV at release phase.
