The direction of the last step of the run-up is incorrect.
In the run-up teaching of fosbury flop, the problem of the last step is usually serious, which mainly leads to the running method of the outer eight characters, and the correct position of the final take-off should still be running in the arc direction; However, the wrong technology often leads to the wrong take-off position, which leads to the route of the last step deviating from the natural extension of the arc, which leads to the separation of the lower limbs in two different directions, which leads to the decomposition of strength. The speed direction of the county support run-up in the last step deviates from the support point, which can not produce the correct take-off, and the upper body will fall to the crossbar prematurely. Reason: Before starting, I was conscious of avoiding the pole or eager to do the back bar action, and the take-off leg subconsciously deviated from the take-off point. Main teaching methods: 1. Repeat the take-off exercise of 1-3, emphasizing the swing direction of the last step of the take-off leg. 2. Place a mark at the jumping point to control the running direction of the last step; 3. Place an appropriate size of synthetic pad or elastic springboard at the take-off point, and repeat the take-off exercise, emphasizing jumping at the take-off point in the exercise; 4. Mark the jumping points and practice repeatedly.
