This study identified and analyzed lower-extremity biomechanical asymmetries in college women\u2019s volleyball players during standard and sport-specific double-leg landing tasks.\n \n Design<\/jats:bold>\n :\n <\/jats:italic>\n Cross-sectional laboratory study.\n \n Methods<\/jats:bold>\n :\n <\/jats:italic>\n Eighteen female college volleyball players were analyzed using standard 3D motion capture techniques during a drop vertical jump and an unanticipated lateral reactive jump task. Repeated-measures multivariate analysis of variance identified asymmetries in kinematic and kinetic variables of each task.\n \n Results<\/jats:bold>\n :\n <\/jats:italic>\n Average symmetry indices ranged from 9.3% to 31.3% during the drop vertical jump and 11.9% to 25.6% during the reactive jump task. During the drop vertical jump, the dominant limb exhibited lower knee abduction moments (\n P<\/jats:italic>\n \u2009=\u2009.03), ankle dorsiflexion moments (\n P<\/jats:italic>\n \u2009=\u2009.02), ankle eversion moments (\n P<\/jats:italic>\n \u2009=\u2009.003) and vertical ground reaction forces (\n P<\/jats:italic>\n \u2009=\u2009.03), and greater ankle inversion moments (\n P<\/jats:italic>\n \u2009=\u2009.001). Both kinematic (\n \u03bb<\/jats:italic>\n \u2009=\u20090.27,\n P<\/jats:italic>\n \u2009=\u2009.03) and kinetic (\n \u03bb<\/jats:italic>\n \u2009=\u20090.12,\n P<\/jats:italic>\n \u2009=\u2009.008) asymmetries were identified during the reactive jump task. The dominant limb exhibited greater peak knee flexion (\n P<\/jats:italic>\n \u2009=\u2009.003) and ankle dorsiflexion (\n P<\/jats:italic>\n \u2009=\u2009.02) angles, and greater ankle dorsiflexion (\n P<\/jats:italic>\n \u2009=\u2009.005) and inversion (\n P<\/jats:italic>\n \u2009=\u2009.03) moments than the nondominant limb.\n \n Conclusions<\/jats:bold>\n :\n <\/jats:italic>\n These asymmetries observed during double-leg landing tasks may predispose volleyball athletes to unilaterally higher ground reaction or muscle forces and ultimately a greater risk of injury during landing.\n <\/jats:p>","DOI":"10.1123\/jsr.2022-0026","type":"journal-article","created":{"date-parts":[[2022,8,8]],"date-time":"2022-08-08T08:00:37Z","timestamp":1659945637000},"page":"85-90","source":"Crossref","is-referenced-by-count":8,"title":["Women\u2019s College Volleyball Players Exhibit Asymmetries During Double-Leg Jump Landing Tasks"],"prefix":"10.1123","volume":"32","author":[{"given":"Jeffrey B.","family":"Taylor","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, High Point University, High Point, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anh-Dung","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Division of Athletic Training, West Virginia University, Morgantown, WV, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey E.","family":"Westbrook","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, High Point University, High Point, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abigail","family":"Trzeciak","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, High Point University, High Point, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin R.","family":"Ford","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, High Point University, High Point, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"1","key":"r1","series-title":"Sports Health","doi-asserted-by":"publisher","first-page":"60","DOI":"10.1177\/1941738117733685","article-title":"Descriptive epidemiology of injuries sustained in national collegiate athletic association men\u2019s and women\u2019s volleyball, 2013\u20132014 to 2014\u20132015","volume":"10","author":"Baugh CM","year":"2018","unstructured":"Baugh CM, Weintraub GS, Gregory AJ, Djoko A, Dompier TP, Kerr ZY.
