专业PVC运动地板的表面能在地板受到一定撞击时，适度的变形，如同一个内有空气的密封式床垫，当在摔跤或者滑倒的时候，密闭泡沫背层技术就会提供缓冲的作用能最大限度的减少运动中的伤害。
Professional PVC sports floor surface energy by a certain impact on the floor, the deformation of the moderate as a sealed inside the air mattress, when in wrestling or slip, airtight bubble back layer technology will provide a buffer role can minimize damage of the movement.

震颤是指运动地板受到撞击变形的范围，这个震颤范围越大越容易引起肢体骨折。震颤有两种：点震颤和区域震颤。
Tremor is refers to the movement floor hit to the range of deformation, the greater the scope of the tremor caused limb fractures, the easier. Tremor has two kinds: tremor and regional tremor.
人在运动时形成的冲击量作用在PVC运动地板表面上会产生震动，地板的结构必须具备震动吸收的功能，也就是指地板应具有吸收撞击能量的性能，运动员在 PVC运动地板上所受到的反撞击力相比在硬地面上来说，如同在水泥地面上的运动要小的多。运动员跳起回落到运动地板时，最起码要有53%以上的冲击量被地板所吸收，从而起到保护运动员的踝关节、半月板、脊髓的作用，使运动员在运动时不致
People in sports form when the amount of impact action will cause vibrations in PVC sports floor surface, the structure of the floor must have the function of shock absorption, is refers to the performance of the floor should have to absorb the impact energy, the athletes in the PVC sports floor compared against shock on hard surface, as in movement on the surface of the concrete is much smaller. Athletes jumped back to the floor of the movement, at the very least, there should be more than 53% of the amount of shock is absorbed by the floor, so to protect the athletes ankle, the action of the meniscus, spinal cord, enable athletes in sports
球回弹性的试验是将篮球从6.6英尺的高度落到运动地板上，测试篮球的回弹高度。这个数据以百分比表示，以篮球在水泥地上回弹的高度为对比标准，反映回弹高度差。室内球类运动比赛规则要求，借助地面进行体育比赛或者训练，如篮球等球类的运动的起跳动作和球体的反弹，要求球体在比赛场地地面上的反弹比较系数应大于或等于90%。
Ball resilience test from fall to 6.6 feet movement is the basketball floor, test the rebound height of basketball. This data is expressed as a percentage to the height of the basketball on the concrete rebound as comparison standard, reflecting the rebound height difference. Indoor ball game rules and requirements, with the aid of the ground for sports or training, such as basketball ball of the takeoff action and the sphere of rebound, require a sphere in the venue bounce on the ground coefficient should be greater than or equal to 90%.
专业运动场地施工的承重负荷及牢固化、动场地施工使用寿命必须达到比赛及训练的要求，如活动篮球架及相关体育设施在地板上移动时，地板的表层和结构不能因此遭到破坏，这就是德国DIN标准所描述的滚动负荷标准和概念。
Professional sports venue construction and strong, the dynamic bearing load the service life of the venue construction must match and training requirements, such as activity and backboard and the related sports facilities on the floor while moving, the surface of the floor and the structure is destroyed, therefore this is what the German DIN standards described in the rolling load standard and concept.
