Description

Technical Field

[0001] The invention relates to the technical field of lower limb jumping training devices, in particular to a lower limb jumping core strength training device. Background Art

[0002] The relevant theories of sports mechanics tell us that jumping power is achieved through the flexion and extension of the athlete's hip, knee and ankle joints, as well as the coordinated efforts of the waist, back, leg muscles and arms, which apply a force to the springboard or diving platform, causing the springboard to generate a reaction force equal to and opposite to the action force, which is transmitted to the athlete, allowing the athlete to gain upward acceleration and jump into the air. Therefore, only by developing the strength of the waist, abdomen, back, hip, knee and leg muscles can the athlete's jumping ability be effectively improved.

[0003] Athletes in the prior art need to circulate the leg jumping force during training to increase the height of the jump. However, traditional lower limb jumping force training equipment is relatively simple, and most of them use structures such as spring plates and rubber bands. For leg muscle training, the spring plate structure is first suitable for jumping training, and when using the rubber band, the foot steps on one end of the rubber band and the other end is hung on the other foot to complete the training operation. However, this operation is not fixed to the rubber band, which is easy to cause the risk of spring injury and affect the subsequent training effect.

[0004] When applying for the present invention, the applicant searched and found that a Chinese patent disclosed a "lower limb jumping core strength trainer" with application number "202011495395.9". This patent mainly relies on trainers to complete the jumping training operation on the surface of a rubber pad, which can strengthen the leg muscles. However, the single-leg muscle jumping of sprint athletes also needs to be strengthened. Therefore, this invention has limitations in use for single-leg muscle training. Therefore, according to the applicant's invention, a single-leg and double-leg jumping training device was invented, which solves the problem of poor single-leg jumping effect of different trainers during training. Summary of the invention
