Talk about the skills of high jump.

1. When hurdling, the available postures are jumping, scissors, tumbling, prone, back crossing, etc. Moreover, these high jump postures require different skills.

2. The run-up of high jump is generally 6 to 8 steps, and the run-up angle is related to the over-pole posture, ranging from 25 to 90. When running up, it is required to accelerate evenly under the condition that the center of gravity moves forward smoothly, so as to run easily and naturally. The last 3~4 steps of the run-up should be to lower the center of gravity. The action structure is different from ordinary running: the upper body leans forward slightly, the arms move greatly, and the heel rolls quickly until the forefoot touches the ground. When jumping in the second step, the direction should be positive, so that the body can be fully promoted and jump forward. When the last step of the run-up is supported by swinging legs, you should actively kneel and send your hips, and the stride legs should take your calves with your thighs. Because of the fast run-up, the run-up leg steps on the ground, swings its legs and arms, and the run-up leg is forced to bend its knees to cushion it. When the knee of the swinging leg swings to be parallel to the knee of the stepping leg, quickly kick the lower leg of the swinging leg forward (toe hook), swing the straight leg upward, and at the same time quickly push the foot straight to complete the stepping action. The swing of the two arms is to cooperate with the movements of the two legs at the beginning of the stride jump, swing upward forcibly from the back of the body, and lift the shoulders outward with the elbows on the same side of the swing leg higher than the shoulders.
