Why does the swing leg of leap high jump rotate inward and press down?
Swing leg internal rotation downward pressure can better solve the problem of over-rod, of course, this technology is not needed at the bottom height, but internal rotation can better brake at the impact limit height, and it is very important to change from horizontal speed to vertical speed, that is to say, the faster the speed, the more internal rotation is needed, and the faster the speed, the higher the jump.

Run straight up from the side and take off with a leg away from the pole. After flying, the swinging leg first crosses the crossbar, then rotates inward and presses down, and the arm swings backward, so that the hips quickly cross the crossbar, and at the same time, the upper body leans forward and twists in the direction of the crossbar, and then the take-off leg is lifted high and rotated outward to complete the action of crossing the crossbar. After crossing the bar, face the bar sideways and swing your legs to the ground first.

Jumping technique in high jump

The leap high jump starts from one side of the swinging leg, and the run-up route is basically a straight line, and the run-up angle is generally 30-60 with the crossbar. Before the formal run-up, the tread point should be measured in advance, and the distance between the take-off point and the projection line of the crossbar is generally 60-80 cm.

The overall run-up is generally10-15m, and the number of steps is 6-8. The speed of the last few steps should be accelerated, the penultimate step is the longest and the center of gravity is the lowest. When the swing foot touches the ground, the knee bends slightly and moves forward. Kick your hips to get ready to jump forward. The last step is a little smaller, let the upper body move forward quickly, send the hips forward, and make full preparations for the transition from horizontal speed to vertical speed.
