Skateboarding is an Olympic event with frequent jumping and landing, where the cushioning effect by foot structure (from arch, metatarsals, etc.) damping performance sports equipment (shoes, insoles, can greatly affect athlete's lower risk of limb injury. characterized formation a "man-shoe-skateboard system," which makes its mechanism different from those other maneuvers, such as basketball vertical jump gymnastics broad jump. Therefore, it necessary to clarify upon landing on skateboard. To achieve this, multibody finite element model right foot, shoe, skateboard was created using Mimics, Geomagic, ANSYS. Kinetic data ollie maneuver were used determine plantar pressure Achilles tendon force at three characteristics (T1, T2, T3). The stress strain metatarsals (MT1-5) then simulated. simulation results had error 6.98% compared actual measurements. During exerted internal soft tissues tends increase. variations highest MT2, MT3, MT4. Moreover, torsion angle MT1 greater than metatarsals. Additionally, displacements MT4 higher parts. This research shows that skateboarders need absorb ground reaction through movements MTs for landing. tissues, bones, ligaments in front may have high risks developed serves valuable tool analyzing mechanisms skateboarding; furthermore, crucial enhance during design shoes reduce potential injuries.
