AN EXPLORATIVE STUDY OF THE DEPENDABILITY OF THE EXECUTION ON ROUTINE SCORING GOAL IN FIELD HOCKEY

ABSTRACT Biomechanical analyzes of field hockey players have been developed. The analysis was made for shooting in the door by video recording from two high-speed video cameras. For each of the blows with the stick, kinematic analyzes were made both from a point of view in a direction perpendicular to the plane of the blow on the ball, and from a rear point of view relative to the athlete. The aim of the development is to establish significant statistical regularities accompanying the repeatability of the stability of the motor habit in the effective execution of the blows on the ball in the hockey goal. Methods The scale of the shooting covers the athlete in general shooting. 8 control markers placed on the front of the stick, the right wrist, the right elbow, the right shoulder, the right and left knees, the right and left feet were used in the video recording from the lateral point of view. The same model for marking control markers is used when shooting the athlete from a rear view. The criterion for the selection of the studied points is to be visible when shooting. Additional lighting is used to increase the contrast required for automated kinematic analysis. Results and analysis Statistical analyzes of the shocks during the shooting were made, including the limit values of the linear velocities of the examined points by the athlete’s body during the execution of the shot in the door. The statistical processing includes variation, correlation, regression and anatomical analyses establishing the stability of the motor habit when performing the stroke by different athletes from the national hockey team. Statistically significant correlation and regression models were established connecting the instantaneous velocity of the blow with the stick on the hockey ball and the instantaneous values of the examined points of the athlete’s body.
