Analysis Of Kinematics Characteristics Of Women’s 3000m Relay Handover Technique In Short Track Speed Skating

Short track speed skating women’s 3000-meter relay is a traditional advantage event in my country,and it is also a gold-winning event in the 2022 Beijing Winter Olympics.In order to further explore the technical principles of handover technology,help coaches of all levels in our country to understand the handover technology in relay events more clearly,and provide scientific basis and reference for coaches and athletes to improve their scientific training and athletic ability,this study selects the British I—SPEED2 high-speed camera captures the handover technology of 8 women’s short track speed skating first-level and above athletes,using the German SIMI-Motion kinematics analysis system and Hanavan human body model to process the captured 16-segment video,using digital low-pass filtering The data is smoothed by way of data smoothing,and the kinematic parameters such as time,displacement,speed,joint angle and angular velocity of 8 athletes are obtained,and the kinematic characteristics of the short track speed skating transfer technique are analyzed and summarized.Use Spearman’s correlation coefficient to analyze the correlation of related kinematics parameters to find out the kinematic factors that affect the quality of handover technology.conclusion as below:1.The handover technology consists of two parts: the preparation phase and the launch phase.The overall time range for the test group to complete the handover technology is0.596s—0.708 s.The ratio of preparation phase time to launch phase time is 1.02:1.2.The change of the hand displacement trajectory of the cross-batterer has an important influence on the direction of the pusher.The change of the elbow joint angle of the crosser has an important influence on the working distance of the pusher.The change in the angle of hip and knee joints the stability of the center of gravity and the effect of force exerting have an important influence.The change of the displacement of the center of gravity on the vertical axis of the passing and receiving athletes has an important influence on the athlete’s speed and movement stability.The smaller the displacement of the baton athlete’s hand in the direction of travel except for the baton athlete,the greater the baton athlete’s speed.The greater the angle change of the elbow,hip,and knee joints of the crosser,the greater the speed of the crosser.The smaller the displacement of the handover and receiver in the direction of travel of the receiver,the greater the speed of the receiver.3.The change of the hand displacement trajectory of the cross-battery athlete has an important influence on the quality of the movement.The change in the angular velocity of the elbow joint of the cross-batter has an important influence on the speed of the baton.The speed of the receiver’s center of gravity on the vertical axis has an important influence on the stability of the movement.The lower the speed of the baton player’s hand except for the direction of travel of the baton player,the greater the baton player’s speed.The greater the hand speed and the angular velocity of the elbow joint of the cross-better,the greater the speed of the baton-receiver.The lower the speed of the handover and receiver in the direction other than the direction of the receiver,the greater the speed of the receiver.Suggestions below:1.It is recommended that coaches attach great importance to the training of relay transfer techniques for short track speed skating,especially the rationality of the technical structure.2.It is recommended that coaches pay attention to technical details including push direction,center of gravity control,movement range,etc.during training.3.It is recommended that coaches pay attention to the balanced development of the athlete’s left and right upper limbs and the ability to control the strength of the core area.
