Abstract  Purpose  To investigate the effects of anterior cruciate ligament injury on mechanical and contractile characteristics of the skeletal muscles of the lower extremity in competitive soccer players through tensiomyography (TMG). Methods  All competitive male soccer players with confirmed acute anterior cruciate ligament tear included underwent resting TMG assessment of muscles of both lower extremities before anterior cruciate ligament reconstruction. The same values were obtained from a sex- and sports level-matched control group. The maximal displacement, delay time, contraction time, sustained time, and half-relaxation time were obtained for the following muscles in all subjects: vastus medialis, vastus laterals, rectus femoris, semitendinosus, biceps femoris, gastrocnemius medialis, and gastrocnemius lateralis. Results  The majority of TMG parameters were higher in the injured compared to the control group. The contraction time of the vastus medialis, vastus lateralis, and rectus femoris was significantly higher in the injured compared to the control group (p = 0.003, p = 0.001, and p
