Abstract

The Landing Error Scoring System (LESS) is successful in identifying high-risk biomechanics. This study analyzed differences in hamstring muscle activation between six collegiate male tennis players and six male swimmers while performing the (LESS). Pre-screening included Functional Movement Screening (FMS) prior to LESS assessment. Muscle activation data was collected through surface electromyography (sEMG). Surface electrodes were placed on the belly of the right and left rectus femoris. Subjects completed three LESS trials from a 30 cm. box. Preliminary descriptive data indicate only slight differences among swimmers right and left rectus femoris. Analysis of tennis players is incomplete at this time.
