Three Dimensional Analysis of Drag-flick in The Field Hockey of University Players

Abstract

The penalty corner one of the most important technique to score the goal in field hockey. The penalty corner depends upon three different technical applications like push, stop and drag. Technical application of drag flick in penalty corner covered maximum number of successful goal. The main aim of this study was to analyze spatial and temporal kinematics in the drag flick of elite field hockey players. Two main drag flickers from Aligarh Muslim University, Aligarh hockey team were selected as a subject for this study. The body weight, Height and Age of each subject ware recorded subsequently Sub₁=65 kg body weight, 180.50cm of height and 19 years of age and Sub₂= 60 kg body weight, 167.00 cm of height and 19 years of age. A static calibration method was used to capture drag flick by Two Cameras, sampling at 50 Hz. Six successful trials at target were selected from each subject for the study.  Videos of selected trials were digitized by the Max Track 3D motion analysis software. The three dimensional (3D) motion was determined from digitized video analysis using 18-point body model together. Results of this study shows that spatial / temporal variable between the players, there exist little difference in stance width in ball contact phase, recommended that little or no difference exist in techniques between both players.

Key points: spatial / temporal, kinematics, drag, digitized.
