The first phase in the long jump in the run, which at the initial stage of training in many children is characterized by instability of pace, lack of clarity of movements and in some cases even a lack of coherence in the work of the hands and feet. Some children perform the run slowly, often with a slowdown, with a stop in front of the repulsion line, which is unusual for the style of the jump.
Children should be taught to perform a run with a gradual increase in speed, which should reach its maximum by the time of repulsion from the bar. During the run-up, set the legs in such a way that, if possible, the heels do not touch the floor, the knees are raised forward and upwards, the feet are lowered parallel to each other. When running, the body is slightly tilted forward, arms bent at the elbows, perform movement strictly back and forth, and keep the head straight. It is necessary to achieve a free run, natural for every child
The most difficult element of the jump is the transition from the takeoff run to the push, which is crucial for the flight range. The last step in the run-up is usually somewhat shorter. The foot is put in place repulsion elastic, with the heel, followed by a very fast transition to the front of the foot. The sharper and faster this movement, the better the push.
The push is carried out not only by the strength of the muscles of the jogging leg, but also due to its sharp extension in the knee, hip and ankle joints, as well as the rapid movement of the maxillary leg bent at the knee forward-up, and active handwork. which simultaneously with the repulsion are sharply thrown forward and upward. The effects of the flight of the legs and arms are of utmost importance for increasing the power of the thrust and contribute to an active, energetic repulsion.
At the end of the repulsion, the flight phase begins, and then the landing phase, as a result of which what is acquired in the take-off run takes place. After pushing away, the jog leg is vigorously pulled up to the flywheel, the arms bent at the elbows are thrown forward and up to the level of the shoulders, and then drop down and back. In-flight, the child is in the grouping position, the arms are at the back, and the body is tilted forward, the head is straight, the child is looking forward. Tilting the torso too far forward usually leads to an earlier lowering of the feet and a premature touch of the landing site. The most advantageous is the group, in which the child is in a sitting position.
