The aim of this paper was (1) to describe the characteristics of the footprint of three groups of women that practise different levels and types of physical activity (sedentary group, elite futsal players and elite hockey players) and (2) to analyse the modifications suffered by their footprints after an intervention period characterised by the sport discipline that they practise. 33 women participated in this study - age: 22.6 ± 3.0, weight: 62.2 ± 7.5 kg, and height: 165.0 ± 5.9 cm -. Five measurements were performed to analyse their type of foot: the Hernández Corvo method, arch index, footprint area, manual measure of navicular height, and tibial-calcaneal angle. These measurements were made twice: at the beginning of the pre-season and at the end of it. According to the Hernández Corvo method, the results showed modifications in the hockey players’ footprint, which also tended to flatten. The futsal players only presented modifications in one foot. Sedentary women did not show any footprint modifications. Therefore, this study has proved that continued physical activity causes footprint modifications in those who practise it.
