Through the examination of run-up and height-touching, we mainly examine the athletes' jumping ability, the coordination of run-up and take-off, the ability to compete for rebounds and the advantages of high-altitude confrontation. Test methods: The run-up and height-touching are tested by electronic height-touching devices, and a half-arc line (with a line width of 5cm) is drawn with the center point of the hanging shadow of the electronic height-touching device as the center, and the arc is the range of run-up. Candidates can take off with one foot or both feet to touch the height when running-up. Touching the highest point in the effective range of the electronic height touch device is its score. Each person tests it three times in a row to get the best score. Note that there is no standard for basketball height touch, the higher the better. But generally, 3.15M is not bad!
