Biomechanical Analysis Of Hockey Pulling Technique

With the successful bid for the 2022 Beijing winter Olympic Games,ice hockey,the official competition of the winter Olympic Games,has been booming again in China in recent years.As the most easy to master and the most helpful to score,the pull shot technique is of great research value.In this paper,the movement stage of the technique is divided and the kinematics data of the pull shot technique of nine ice hockey players are analyzed.This paper attempts to explore the general rules of hockey pull shot movement technology and the key movement technology in each stage,so as to put forward scientific suggestions for the training of this technology more pertinently.In this paper,according to the principles of sports biomechanics and kinematics,three-dimensional high-speed camera method is used to shoot the action of hockey puck pull shot technology.The APAS System was adopted to carry out three-dimensional fixed-point and multi-point analysis of The main joints of The human body and The head of the hockey stick,and EXCEL was used for data processing and chart drawing.After the analysis of the obtained data,the following conclusions are drawn:(1)the time taken by the whole pull shot technique is very short,no more than 1 second;(2)The vertical displacement of the body's center of gravity increases gradually in the pull stick stage until it reaches the maximum value in the hitting stage;(3)The faster the speed of the hockey stick head,the easier it is to have a positive impact on the speed of the shot;(4)Shoulder joint,elbow joint Angle changes directly affect the speed of the hockey stick,which affects the ball out of the batting phase of the speed.In the push-off stage,the change of hip Angle directly affects the twisting work of the body,thus affecting the ball speed.According to the above conclusions,it is suggested to pay attention to the order of force of each joint of the body,so that the power is transferred from the bottom to the top in turn.Pay attention to strengthen the physical coordination.In particular,attention should be paid to improving the stability of the lower limbs and the explosive force of the upper limbs.
