Measure the height of the vertical jump in place, lift the middle finger to touch the ruler on the wall, measure the height when bouncing, minus the vertical height of the middle finger on the upright arm, the difference is the vertical jump height. Second, the findings 1. General information: a total of 36 skaters, their
