背越式跳高助跑教学(国外英文资料) Technical elements of the race Technical characteristics Is the main characteristic of fosbury style high jump run-up arc run-up, run-up line is commonly J its advantage is: 1. The run-up of the preparatory period is a straight line or small curvature line, so for all the acceleration and velocity. The transition to the arc is smooth and natural, avoiding pauses or slowdowns. The curvature of the arc is reduced by a large amount, and the body gradually increases the internal frequency. The final step is about 20 degrees to 30 degrees in the horizontal bar to ensure that the human body is in the air and has a proper vertical displacement relative to the horizontal bar. Run-up technology The task of the running is to obtain the necessary horizontal speed and create conditions for the increase of the jumping effect and the smooth crossing of the crossbar. The higher jump of the back is generally used in the eight to 12 stages of the run, the line of the line and the arc. 1. Linear run-up technology: similar to short circuit on the way to run technology, ran into the proper forward, stable high center of gravity and the upper body after push adequately powered, front leg actively, two arms coordination swing sharply; Arc running technique: the body is gradually introverted, increasing the swing of the lateral leg arm, keeping head and torso in a straight line to the inside. The whole process of the run should have a clear acceleration and a strong sense of rhythm, especially in the last few steps, and the final step is the fastest. Problems that arise in the teaching of running Improper curvature of the running arc Frequently, run-up in learning curve run-up, curve is not the right question, mainly will appear the following error: error 1: in the run-up, body introversion is not increase gradually, but the start into the arc, introversion, the largest body ran to the last two steps when the body stands erect, instead in run-up line ran straight unreas
