The Young Female Long Jump Two Levels Of Athlete Approaches Take Off The Technology Kinematic Analysis

Through (13-15 year old) the approach takes off the technical photographic analysis to the young female long jump two levels of athletes, studies the young female long jump athlete and takes off in the process technical rule in the approach and the characteristic, like the approach speed level, the approach speed to takes off the technical influence, takes off in the process human body parameter and so on. This article uses literature research techniques and so on material law, photographic analysis law, mathematical method of average carries on the quantitative analysis to various technical link, and described its kinematics characteristic. Compare its kinematics characteristic and the high level athlete, as well as between the juvenile athletes does compares, discovers the shortcoming and the insufficiency. And draws following conclusion: 1. young female long jump two level of athlete's approach speeds and the high level female long jump athlete compares the disparity to be big, needs to strengthen the absolute speed the training, but the young female long jump two levels of athletes are worth in the approach aspect affirming, they when approach maintains the accelerating regime throughout, the maximum speed appears last in step, the approach speed use factor is high. 2. Young female long jump two levels of athletes instantaneous and take off in the process in the board to swing the leg knee angle oversized folds not tightly. It instantaneous is taking off the leg knee angle in the board, takes off the leg hip angle, as well as takes off in the process to take off the leg to bow the angle technical parameter all to be smaller than most greatly the high level female long jump athlete. 3. Young female long jump two levels of athletes take off to the board instantaneous, the center of gravity speed scaled height of burst horizontal athlete is much slower. Takes off the leg knee angle and the hip angle is also smaller than the high level contestant. 4. young female long jump two levels of athletes in take off leap the angle to the board instantaneous center of gravity vertical velocity and the center of gravity all in the standard scope, is almost the same with the high level athlete, this should be their superiority and the characteristic.
