Sponge training long jump device

Abstract

The invention relates to the technical field of training sports equipment, in particular to a sponge training long jump device. The training long jump device comprises a training pit and a sponge frame which is provided with a sponge, and a following device is further arranged between the bottom of the training pit and the sponge frame. In the using process, a jumper can fall into the sponge inside the sponge frame after taking off at the take-off end, a good cushion protection effect is achieved, and the discomfort due to the fact that sand in a traditional sand pit enters shoes can be avoided; when the sponge frame is under the gravity of a human body, the sponge frame moves downwards through spring trundles, the sponge frame is pressed on the following device, due to inertia, the sponge frame can stop after moving by a certain distance in the stress direction on the following device, the impact force to the human body due to sudden stop is avoided, the jumper slides by a certain distance in the motion direction on the simulation sand pit, and thus the body of a trainee can be effectively protected.
