Part of these alterations can be magnified when these athletes are\n                    fatigued. So far, little is known whether fatigue-induced landing alterations\n                    persist after return-to-sport. Therefore, the aim of this study was to evaluate\n                    whether these alterations persist in the six months following return-to-sport.\n                    Sixteen anterior cruciate ligament reconstructed athletes performed five\n                    unilateral hop tasks before and after a fatigue protocol. The hop tasks were\n                    executed at three different time points (return-to-sport, 3 and 6 months\n                    post-return-to-sport). A 2-by-3 repeated measures ANOVA was performed to\n                    evaluate whether fatigue-induced landing alterations persisted 3 and 6 months\n                    following return-to-sport. At 6 months following return-to-sport, fatigue still\n                    induces a reduction in hamstring medialis activation and an increase in the knee\n                    abduction moment during a vertical hop with 90-degree inward rotation. Most\n                    fatigue-induced landing alterations present at the time of return-to-sport\n                    normalize after resumption of sports activities. However, a larger knee\n                    abduction moment in the injured leg after resumption of sports activities can\n                    still be observed.<\/jats:p>","DOI":"10.1055\/a-2108-5219","type":"journal-article","created":{"date-parts":[[2023,7,25]],"date-time":"2023-07-25T22:39:11Z","timestamp":1690324751000},"page":"830-838","source":"Crossref","is-referenced-by-count":2,"title":["Fatigue-induced
