We allocated 45 participants (21 male, 24 female) demonstrating knee, hip, and trunk frontal plane mechanics associated with elevated anterior cruciate ligament injury risk to one of three groups (control, AS, or EE). Participants mimicked an avatar performing five sets of eight repetitions of exemplary single-leg squats. AS participants were given the added option of choosing the color of their avatar. EE participants received real-time biofeedback in the form of green highlights on the avatar that remained on as long as the participant maintained pre-determined \u2018safe\u2019 frontal plane mechanics. We measured peak frontal plane knee, hip, and trunk angles before (baseline) and immediately following (post) the intervention. The control group demonstrated greater increases in knee abduction angle (\u0394 = +2.3\u00b0) than did the AS (\u0394 = +0.1\u00b0) and EE groups (\u0394 = \u22120.4\u00b0) ( p = .003; \u03b7\n                    <jats:sup>2<\/jats:sup>\n                    <jats:sub>p<\/jats:sub>\n                    = .28). All groups demonstrated increased peak hip adduction ( p = .01, \u03b7\n                    <jats:sub>p<\/jats:sub>\n                    <jats:sup>2<\/jats:sup>\n                    = .18) (control \u0394 = +1.5\u00b0; AS \u0394 = +3.2\u00b0; EE \u0394 = +0.7\u00b0). Hip adduction worsened in all groups. AS and EE motivation strategies appeared to mitigate maladaptive frontal plane knee mechanics.\n                  <\/jats:p>","DOI":"10.1177\/00315125241246361","type":"journal-article","created":{"date-parts":[[2024,4,24]],"date-time":"2024-04-24T16:09:19Z","timestamp":1713974959000},"page":"687-706","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Either Autonomy Support or Enhanced Expectancies Delivered Via Virtual-Reality Benefits Frontal-Plane Single-Leg Squatting Kinematics"],"prefix":"10.1177","volume":"131","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1477-9428","authenticated-orcid":false,"given":"Jennifer A.","family":"Hogg","sequence":"first","affiliation":[{"name":"Department of Health and Human Performance, University of Tennessee Chattanooga, Chattanooga, TN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8433-7329","authenticated-orcid":false,"given":"Gary B.","family":"Wilkerson","sequence":"additional","affiliation":[{"name":"Department of Health and Human Performance, University of Tennessee Chattanooga, Chattanooga, TN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shellie N.","family":"Acocello","sequence":"additional","affiliation":[{"name":"Department of Health and Human Performance, University of Tennessee Chattanooga, Chattanooga, TN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bryan R.","family":"Schlink","sequence":"additional","affiliation":[{"name":"Battelle Memorial Institute, Columbus, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, The University of Tennessee Chattanooga, Chattanooga, TN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dalei","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, The University of Tennessee Chattanooga, Chattanooga, TN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory D.","family":"Myer","sequence":"additional","affiliation":[{"name":"Emory Sports Performance And Research Center (SPARC), Flowery Branch, GA, USA"},{"name":"Emory Sports Medicine Center, Atlanta, GA, USA"},{"name":"Department of Orthopaedics, Emory University School of Medicine, Atlanta, GA, USA"},{"name":"The Micheli Center for Sports Injury Prevention, Waltham, MA, USA"},{"name":"Youth Physical Development Center, Cardiff Metropolitan University, Wales, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jed A.","family":"Diekfuss","sequence":"additional","affiliation":[{"name":"Emory Sports Performance And Research Center (SPARC), Flowery Branch, GA, USA"},{"name":"Emory Sports Medicine Center, Atlanta, GA, USA"},{"name":"Department of Orthopaedics, Emory University School of Medicine, Atlanta, GA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,4,24]]},"reference":[{"key":"bibr1-00315125241246361","doi-asserted-by":"publisher","DOI":"10.4085\/1062-6050-320-17"},{"key":"bibr2-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1123\/jmld.2017-0011"},{"key":"bibr3-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1016\/0167-9457(89)90020-1"},{"key":"bibr4-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-015-3727-0"},{"key":"bibr5-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1123\/jsr.2017-0391"},{"key":"bibr6-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-023-06639-0"},{"key":"bibr7-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1080\/02701367.2005.10599260"},{"key":"bibr8-00315125241246361","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2012.00458"},{"key":"bibr9-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2020.05.001"},{"key":"bibr10-00315125241246361","volume-title":"Statistical power analysis for the behavioral sciences","author":"Cohen J.","year":"1988"},{"key":"bibr11-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiomech.2016.04.004"},{"key":"bibr12-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2016.07.107"},{"key":"bibr13-00315125241246361","doi-asserted-by":"publisher","DOI":"10.1007\/s40279-016-0519-8"},{"key":"bibr14-00315125241246361","first-page":"1","volume":"4","author":"DiCesare C.
