  1. Comfort issues:

  The surface of professional PVC sports flooring can be moderately deformed when impacted, like a sealed mattress with air inside. When you are wrestling or slipping, the cushioning effect provided by the closed foam backing technology can minimize the impact. Sports injuries.

  2.Problems with tremors:

  Tremor refers to the area where the floor is deformed by impact. The larger the tremor range, the more likely it is to cause a fracture. There are two types of tremor: point tremor and regional tremor.


  3.Problems with vibration absorption:

  The impulse formed by people during exercise will cause vibration on the surface of PVC sports floor. The structure of the floor must have the function of shock absorption, which means that the floor should have the ability to absorb impact energy. The impact force is much smaller than on a hard ground, such as on a concrete ground. That is to say, when athletes jump and fall to the floor, at least 53% of the impact should be absorbed by the floor, so as to protect the athlete's ankle, meniscus, spinal cord and brain, so that people will not be affected during exercise. hurt. Its protective function also considers that a person cannot affect the adjacent people when exercising on the PVC sports floor. This is the concept of vibration absorption, vibration deformation and extended deformation described in the German DIN standard.

  4.Question of friction coefficient:

  Studies have shown that 12% of basketball players' injuries occur during a spin in place. The coefficient of friction of a sports floor indicates whether the floor has too much friction (which reduces the flexibility of rotation) or is too slippery (which increases the risk of slipping). Considering the athlete's mobility and safety, the friction coefficient should be the best value between 0.4-0.7. The coefficient of friction of PVC sports floor is generally maintained between this coefficient. The coefficient of friction of professional PVC sports floor is 0.57. It has sufficient and moderate friction to ensure the stability of the movement and maintain it in all directions of movement. Consistency and regularity of friction performance to ensure flexible movement and in-situ rotation without any obstruction.

  5.The problem of ball resilience:

  The ball resiliency test is to drop the basketball from a height of 6.6 feet onto the sports floor to test the rebound height of the basketball. This data is expressed as a percentage, and the rebound height of the basketball on the concrete floor is used as a comparison standard to reflect the difference in rebound height. The rules for indoor ball games require that the ground be used for sports competitions or training, such as basketball and other ball sports. Take-off movements and ball bounces. The ball bounce comparison coefficient on the ground of the playing field should be greater than or equal to 90% PVC sports floor has outstanding and stable ball resilience performance, there is no elastic dead point on the floor, and its rebound comparison coefficient can reach up to 98%.

  6.Questions on exercise energy return:

  This refers to the sports energy returned by the PVC sports floor when athletes exercise to improve sports performance.

  7.Problems with rolling loads:

  The load-bearing load and firmness of professional sports floors must meet the requirements of competition and training. For example, when the movable basketball rack and related sports facilities are moved on the floor, the surface and structure of the floor cannot be damaged. This is the Shanghai DIN standard. Described rolling load standards and concepts.
