1, walking method
In the usual case, using their own walk, the number of assisted steps multiplied by 2 minus 2 is equal to the number of steps, such as assisted 8 steps (8 × 2-2 = 14 steps). If the number of assisted steps exceeds 10 steps, then each additional assisted step increases the distance traveled by two steps, such as assisted 12 steps, that is (10 × 2-2) + 2 × 2 = 22 steps. After repeated running aids to make adjustments, and finally determined.
2, fixed method
After the running distance is determined, the practice should be done to start the posture back to fixed, start the first step out of the leg fixed, fixed distance to help run, accelerate the rhythm of fixed. This will improve the accuracy of the assisted running.
3, mobile method
Draw a baseline 15 to 20 meters away from the front edge of the jump area. Students first try to jump from the baseline must start to run, the teacher or students in the jump area outside the observation of the test jumpers jump feet landing point, to see whether it can be stepped on the right, if more than the jump area, the test jumpers to guide their own feet to measure out more than the number of feet, and then from the baseline backward to move the corresponding number of feet. Conversely, move the starting line forward if it is not stepped on.
4, nine and seven method
The so-called nine and seven method is to walk nine steps and run seven steps of the measurement method. Starting from the front of the jump area, walk nine steps in the opposite direction of the run (normal walking), and then run seven steps (accelerated running), the landing point of its last step, is the starting point of the run.

The starting position of running:
The starting position of running has a direct impact on the stability and accuracy of running. There are two types of starting positions: one is from a static state, generally using two legs slightly bent, two feet parallel to the left and right of the "semi-squatting", or two legs before and after the separation of the "standing" starting position.
The other is to walk a few steps or take a jump step combined with the first marking point, the start of the march between the start. In the first method, the first three steps have less variation in stride length and speed, which is conducive to improving the accuracy of the running aid. In the second method, the run-up is more natural and the movement is more relaxed. However, because it is dynamic, the position and speed of each step on the sign is not easy to control, and it puts a higher demand on the accurate pedal.
