Description

technical field [0001] The invention relates to the technical field of sports training equipment, in particular to a jumper for physical education. Background technique [0002] In physical education teaching, the jumper is one of the commonly used equipment, especially in sports such as long jump and pommel horse. The existing take-off device enables athletes or students to obtain jumping assistance through the rebound force of the upper end of the spring to the pedal. This kind of take-off device is fixed by the spring, and the spring will be distorted when stepping on the pedal during take-off, which will affect the effect of jumping assistance. For beginners in long jump Students with pommel horses are extremely unfavorable, and it is not convenient for them to master sports skills faster. In addition, the existing jumper has poor stability, is easy to slide when taking off, has poor reliability, and is inconvenient for athletes or students to step on it accurately when...
