Abstract

With the growing prosperity of the development of the national economy and overall national strength , China 's sports undertakings boomed , track and field events have become the forefront of the development project . The long jump is one of the track and field sports , sports curriculum requirements required course , is an exercise and strengthen the physique sports . It has the technical flexibility and agility in various parts of the body are involved in activities and easy a sporty bone injury caused by long jumpers . The complete long jump by the run-up , takeoff , vacated , landing four phases . How to improve jump distance and avoid sports injuries has been the core concerns of the coaches and athletes . Throughout the long jump process , the trajectory of the body center of gravity of the athletes presented belongs Projectile Motion curve . Long Jump technology is the most critical aspects affecting the results of the long jump take-off so that the momentum of the total body center of gravity change very rapidly to obtain Jumping speed and flight angle , certain Tengqi speed and flight angle largely determine the flight distance of the long jump and largely determine the results of the long jump . The ideal inclination of the body during exercise in the long jump take-off , the mechanics , get the best off angle , to provide a theoretical basis for scientific guidance to training . Biomechanical analysis , the body's natural protection of the weak knee occlusion model in the long jump process , while knee is also in every link in the long jump have played an indispensable role . Angle of 160 degrees to 175 degrees from the mechanical angle of the knee injury analysis , numerical simulation using ANSYS , presented the most intuitive diagram , hope can arouse enough attention , exercise and training in the future to avoid knee the generation of the 160 -degree angle of the joint , and thus protect the athletes to be avoided by the Biomechanics of sports injuries and prolong the life of the athlete 's sport .
