This study investigated the short-term effects of barefoot running on selected parameters of the anteroposterior and mediolateral components of the Ground Reaction Force (GRF) in runners used to wearing athletic shoes. Seventy-one recreational runners, inexperienced in barefoot running, ran at a self-selected speed for a distance of 9 meters on a fixed floor equipped with force platforms, under two conditions: shod and barefoot. The braking and acceleration peaks of the anteroposterior component, as well as the minimum and maximum peaks of the mediolateral component were obtained. The braking peak was lower, while the acceleration peak was higher in barefoot running. In contrast, the magnitude of both the minimum and maximum peaks were greater in the barefoot condition. In summary, barefoot running acutely alters selected parameters of the anteroposterior and mediolateral components of the FRS related to the overload and performance of runners used to wearing sports shoes.
