The impact of a person's motion upon jumping into the plane of the wooden floor will produce impact. The structure of the sports wooden floor must be equipped with an impact absorption function. That is, when the athlete jumps up and down to the wooden floor, he must have more than 53% of the impulse on the wooden floor. The shock absorption structure absorbs and protects the ankle, the meniscus, the spine, and the brain of the person so that the person will not be injured when exercising. At the same time, it is also necessary to consider that when moving on a wooden floor, it cannot affect adjacent people. This is the vertical deformation rate. The protection function of sports wood floor also includes the selection of the material of the floor surface layer, and it is necessary to select the species with moderate hardness, slight deformation, and long fiber structure (not easy to puncture) to avoid injury to the athlete's skin.
