Most gymnastics mats are designed to absorb impact—but what happens after impact is just as important. When a gymnast lands, the mat compresses and then rebounds, returning energy back into the athlete’s body. If this rebound happens too quickly, it can increase joint stress, disrupt balance, and reduce landing control....

Traditional gymnastics mats are built around a fixed cushioning profile: they are either soft or firm, regardless of how an athlete lands. However, gymnastics movements vary dramatically, from slow balance holds to explosive dismounts, making a single stiffness level inherently limiting. To overcome this limitation, material engineers are developing shear-thickening...
