The purpose of this study was to investigate the effect of a simulated soccer test on the functional hamstrings‐to‐quadriceps ratio ( H ecc : Q con ) in female soccer players. Fourteen amateur players (age, 26.1 ± 4.6 years; height, 168 ± 12 cm; body mass, 62.7 ± 5.5 kg; body fat, 23.7 ± 2.2%) performed the modified L oughborough I ntermittent S huttle T est (modified LIST ). Isokinetic strength assessments of the hamstrings and quadriceps on the dominant and non‐dominant legs at 120°/s were performed before and immediately after the modified LIST . H ecc : Q con was calculated as the ratio of the peak eccentric torque of the hamstrings to the peak concentric torque of the quadriceps. A two‐way univariate analysis of variance was used to assess the effect of time and leg dominance on H ecc : Q con . The main results showed that the modified LIST led to a significant decrease in H ecc : Q con in the dominant (−14.1%) and non‐dominant legs (−8.0%) ( P = 0.02). However, this decrease was not significantly different between dominant and non‐dominant legs ( P = 0.42). These results reflect a greater risk of hamstrings tears and ACL sprains at the end of soccer matches.
