[0002] In ordinary long jump training or competition, the traditional method is to use sand pits to measure athletes. This measurement method not only has high error and high labor costs, but also requires special personnel to measure. Changes are likely to bring errors to subsequent athletes. After the athletes walk out of the bunker, they will take the sand out of the bunker, and a small amount of sand will enter the athlete's shoes, which will increase the risk and bring great work to the sports staff. difficulty

In addition to bunker long jump, when jumping on the ground, playground runway and other roads, the athlete has no cushion when landing on the ground, and the athlete is prone to injury if he is not careful, and even if it is performed on the existing plastic track, the elastic cushion of the runway surface is not enough. , there are still security risks

In addition, in general, there is no special long jump venue for outdoor long jump entertainment activities. The athletes either go to the playground together, or draw lines on the spot to measure, which is extremely inconvenient
