%X Although the effects of running on plantar pressures have been detailed on several surfaceswith different hardness, there is a lack of studies assessing the mechanical behavior analysis byin-shoe plantar pressure sensors on different hardness mats during running. The aim of the presentstudy was to determine in-shoe maximum forces and peak plantar pressures on mats with differenthardness, such as hard, soft and air chamber mats, during running. A cross-over study was carriedout including 36 amateur runners from a sport center. The maximum force and peak pressures of thefoot plantar region were analyzed on three different mat hardnesses —soft and hard polyurethanefoam mats and air chamber mats—by in-shoe instrumented insoles. Running on soft polyurethanefoam mats presented reduced maximum forces in the whole plantar region andmainly peak pressuresin the anterior part of the foot plantar region, such as the toes and first to fourth metatarsal heads,compared to hard polyurethane foam and air chamber mats. The peak pressure in the fifth metatarsalhead was specifically reduced during running on soft compared to hard polyurethane foam mats, andrunning on these soft mats decreased calcaneus peak pressures compared to running on air chambermats. Running on air chamber mats increased peak plantar pressures in the first metatarsal headcompared to running on hard polyurethane foam mats. The mechanical behavior of mats of differenthardness could be used to adjust the degree of impact on plantar pressures to determine the mostappropriate materials and hardness for running.
