The role of the vastus medialis (VM) of the quadriceps, as a medial patellar stabilizer, has been linked to pathomechanics of patellofemoral dysfunction, which is a high-prevalence pathology, especially in women. From the anatomical point of view, it has been described that this muscle has two large groups of fibers that are differently aligned, which could indicate a subdivision of the VM in an oblique (VMO) and a longitudinal portions (VML) (1,2). However, there are few bibliographic records that support this assumption from the functional point of view (3). The aim of this study was to compare the activation level of the oblique and longitudinal portions of the vastus medialis during an open kinetic chain exercise of the knee. The purpose was to contrast the following hypothesis: During a knee extension exercise, "The activation level of the VMO is higher than the VML’s". The acceptance or rejection of this hypothesis may provide new information about the functionality of the compartmentalization of this muscle.
