Abstract: 19 elite baseball players (male: n = 9; female: n = 10) participated in this study. In a repeated measures study design, participants were required to attend to a testing session where they performed a 6 × 40 m repeated sprint ability (RSA) test with 20 s rest interval between 40 m bouts. A 2 (time: pre-, post- test) × 2 (sex: male, female) repeated measures analysis of variance was utilised to study the changes in LESS scores before and after the RSA exertions. Before (pre-test) and after (post-test) the RSA, all participants were instructed to perform three successful trials of a drop vertical jump task (DVJ) off from a 30 cm elevated platform. There was no discernible gender difference in LESS scores. Repeated sprint exhaustion did not appear to have an impact on the results, but more investigation into the various types of fatigue may provide richer details about their contributions to players’ landing kinematics. Baseball players, especially fielders, may find the LESS to be quite useful for screening their risk of lower limb injuries. To further assess the injury risk among pitchers, future studies might also take a single-leg LESS variation into account.
