This study aimed to investigate the influence of explosive quadriceps\u00a0strength on ACL\u2010related sagittal\u2010plane landing mechanics in females with and without ACL reconstruction (ACLR).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Quadriceps\u00a0explosive strength and landing mechanics were assessed in 19 ACLR and 19 control females during isometric contractions and double\u2010\u00a0and single\u2010leg jump landings. A stepwise multiple linear regression model determined the variance in each of the landing biomechanics variables for the ACLR limb and nondominant limb of controls that could be explained by the group, rate of torque development\u00a0and\/or their interaction. If peak kinetic variables could be predicted by the rate of torque development or interaction, additional analyses were conducted, accounting for knee flexion as a covariate in the regression model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During single\u2010leg landings, ACLR females exhibited greater knee flexion at initial contact than controls (<jats:italic>p<\/jats:italic>\u2009=\u20090.04). Greater quadriceps\u00a0rate of torque development predicted higher peak posterior ground reaction force and anterior tibial shear force in both groups (<jats:italic>p<\/jats:italic>\u2009=\u20090.04). However, after controlling for knee flexion angle at those peak forces, quadriceps rate of torque development was not predictive. In double\u2010leg landings, greater explosive quadriceps strength was associated with quicker attainment of peak knee extension moment and posterior ground reaction force in the ACLR limb (<jats:italic>p<\/jats:italic>\u2009=\u20090.03).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Regardless of ACL injury status, females with greater explosive quadriceps strength adopted safer single\u2010leg landings through increased knee flexion, potentially mitigating ACL loading despite encountering higher peak forces. During double\u2010leg landings, a greater explosive quadriceps strength of the ACLR limb is associated with faster achievement of peak force upon landing. Incorporating explosive quadriceps strengthening into post\u2010ACLR rehabilitation and injury prevention programmes may enhance landing mechanics for reducing primary and subsequent ACL injury risks.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>Level II.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ksa.12222","type":"journal-article","created":{"date-parts":[[2024,4,30]],"date-time":"2024-04-30T05:04:18Z","timestamp":1714453458000},"page":"2013-2022","source":"Crossref","is-referenced-by-count":5,"title":["Differential influence of quadriceps rate of torque development on single\u2010 and double\u2010leg landing mechanics in anterior cruciate ligament reconstructed and control females"],"prefix":"10.1002","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0809-3152","authenticated-orcid":false,"given":"Yu\u2010Lun","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Physical Education and Sport Sciences, College of Sports and Recreation National Taiwan Normal University Taipei City Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3891-0539","authenticated-orcid":false,"given":"Colin M.
