Problem Statement: The drag-flick performance can be improved by understanding the effect of kinematic and anthropometric factors on the ball velocity of the drag-flick shot in field hockey. Purpose: The purpose of this study was to identify the association and influence of the selected kinematic and anthropometric factors on the ball velocity of the drag-flick in field hockey. Methods: The kinematic factors of 64 drag-flicks of 16 (female = 8, male = 8) national elite hockey players were measured through 3D biomechanical analysis using VICON motion capturing system and MATLAB software. Pearson correlation and regression analysis were used for statistical analysis. Results: The ball velocity had significant correlation with drag length (r = 0.70, p < 0.01), drag time (r = 0.29, p < 0.05), drag velocity (r = 0.59, p < 0.01), stance width (r = 0.53, p < 0.01), average right knee angle (r = -0.36, p < 0.01), average left elbow angle (r = -0.31, p < 0.05), age (r = -0.32, p < 0.05), weight (r = 0.36, p < 0.01), and height (r = 0.39, p < 0.01). Drag length (β1 = 4.63), stance width (β2 = 8.19), average right knee angle (β3 = -0.07), age (β4 = -1.62), and height (β5 = 0.15) had significant (p < 0.05) influence on the ball velocity of the drag-flick. Conclusion: To make a drag-flick with high ball velocity, the players maximize their ball drag length and stance width while minimizing their average right knee angle. In addition, the players' height had a significant and positive contribution towards the ball velocity. The coaches should focus on the drag length and stance width of the flickers to increase their performance. [ABSTRACT FROM AUTHOR] |
