Rate of torque development declines at lower relative torque outputs in acl reconstructed limbs

We analysed the rate of torque development (RTD) drop-off characteristics of forty anterior cruciate ligament (ACL) reconstructed (ACLR) subjects during maximal quadriceps voluntary isometric contractions (MVIC). We found that the RTD of ACLR limbs drops at a lower percentage of their maximum torque output compared to their contralateral limb, but that this drop-off occurs at the same time for both limbs. This exertion dependent component of ACLR quadriceps dysfunction could limit performance during high-intensity activities.
