La electromiografía de superficie ha sido una técnica usada para describir la actividad muscular durante la carrera. Sin embargo, hay poca literatura que analice el comportamiento de la coactivación muscular en corredores, describiendo el efecto entre dos técnicas asociadas al contacto inial, tal como el uso de retropié y antepié. El propósito de este estudio fue comparar los niveles de coactivación desarrollados en la extremidad inferior, utilizando dos técnicas de carrera, antepié

Surface electromyography has been a technique used to describe muscle activity during running. However, there is little literature that analyses the behaviour of muscle coactivation in runners, describing the effect between two techniques associated with the initial contact, such as the use of rearfoot (RF) and forefoot (FF). The purpose of this study was to compare muscle coactivation levels developed in the lower limb during two running techniques
