The purpose of this study was to determine whether a double\u2010leg landing training program with real\u2010time visual feedback improves frontal\u2010plane mechanics during double\u2010 and single\u2010leg landings. Knee abduction angles and moments and vertical ground reaction forces (<jats:styled-content style=\"fixed-case\">GRF<\/jats:styled-content>) of 21 recreationally active women were quantified for double\u2010 and single\u2010leg landings before and after the training program. This program consisted of two sessions of double\u2010leg jump landings with real\u2010time visual feedback on knee abduction moments for the experimental group and without real\u2010time feedback for the control group. No significant differences were found between training groups. In comparison with pre\u2010training data, peak knee abduction moments decreased 12% post\u2010training for both double\u2010 and single\u2010leg landings; whereas peak vertical <jats:styled-content style=\"fixed-case\">GRF<\/jats:styled-content> decreased 8% post\u2010training for double\u2010leg landings only, irrespective of training group. Real\u2010time feedback on knee abduction moments, therefore, did not significantly improve frontal\u2010plane knee mechanics during landings. The effect of the training program on knee abduction moments, however, transferred from the double\u2010leg landings (simple task) to single\u2010leg landings (more complex task). Consequently, <jats:styled-content style=\"fixed-case\">ACL<\/jats:styled-content> injury prevention efforts may not need to focus on complex tasks during which injury occurs.<\/jats:p>","DOI":"10.1111\/sms.12051","type":"journal-article","created":{"date-parts":[[2013,1,24]],"date-time":"2013-01-24T16:43:06Z","timestamp":1359045786000},"page":"692-699","source":"Crossref","is-referenced-by-count":16,"title":["Real\u2010time feedback on knee abduction moment does not improve frontal\u2010plane knee mechanics during jump landings"],"prefix":"10.1111","volume":"24","author":[{"given":"M.
