Low-resilience competitive gymnastic floor mat inner lining

The invention relates to sport equipment, and in particular discloses a low-resilience competitive gymnastic floor mat inner lining. The low-resilience competitive gymnastic floor mat inner lining isformed by combination of a plurality of buffer layers and is characterized in that the floor mat inner lining includes a buffer layer A, a buffer layer B, a buffer layer C, a buffer layer D, a bufferlayer E and a buffer layer F from top to bottom, wherein the buffer layer A, the buffer layer C and the buffer layer E are all cross-linked polyethylene foam materials, and the buffer layer B, the buffer layer D and the buffer layer F are all soft polyurethane foam materials. The inner lining has the advantages of simple structure and convenience for processing and assembling, the drop hammer impact performance meets the requirements of standards of International Federation of Gymnastics, and the buffer layers can effectively reduce the rebound height of the floor mat, and thus is beneficial to smooth landing of athletes and improvement of the action completion quality.
