Analysis Of The Kinematic Characteristics Of The Technique Of Outstanding 200m Breaststroke Female Athlete

Swimming is a long history of sports, but also includ es four competitiv e swimming strokes. Where four kinds of competitive swimming breaststroke is th e most demanding position in technology, swim into the s lowest one p roject, three strokes compared to other m ore complex techniques. Nearly 50 years, with the passage of tim e, along with the continuous improvement of rules of technical movements breaststroke significant changes. Technology there is still much room for improvement of young fem ale athletes, each athlete on to un derstand and apply new technologies have a greater difference.The main purpose of this project is to study the nati onal tier of young fe male athletes in action breaststroke swim into the process of analyzing the kinem atic characteristics which e xist in the speed, a ngle, displacement, etc., to identify the differences, indicating that factors that af fect the sp eed of change, and while s ix players to compare their excellent technical movements.By studying abroad most of the relevant literature, the real-time with the athletes shoot underwater video technol ogy, visiting professors of you, combined with solid material related experim ents, the use of logical analysis of 6 200 m breaststroke breaststroke elite athlete conducted technical analysis.Through analysis of the 200-m eter breaststroke athletes, the following conclusions:Athlete’s body position, angle, velocity and displacement, have better posture reflects the various kinem atic indicators appear consistent, but a space appear out of sync, it may be due to an insufficient amount of joints.Leg technology, angle, velocity a nd displacement, are more obvious, and its advantage is reflected in many aspects, open water resistance commitment to better promote the forward force of the body, giving a larger supplement.Athletes arm technology, angle, velo city and displacem ent, three kinem atic aspects, all have varying degrees of nonlin ear evolution, and the data obtained from the image, the develop ment arm with each jo int angle is optim ized for the actio n, otherwise will hinder movement and technological development.Athletes in the breaststroke technical aspects of coordination, coordination of the various joint angles appear lag, while ensuring maximum velocity, displacement occurs down too m uch, resulting in excessive consum ption of ener gy and commitment than the angle of the optimization problem.
