High loads on the knee during landing or changes of direction can lead to a valgus shift of the knee, known as Dynamic Knee Valgus (DKV). Many studies have shown that a large shift in DKV is a predisposing factor for knee injuries and disease, such as anterior cruciate ligament injury (ACL), patellofemoral pain syndrome or osteoarthritis. Functional training could be a great tool to reduce DKV. Thus, in this pilot study, nine male youth soccer players (mean age: 16.4 \u00b1 0.2 years) took part in six weeks of functional training program. DKV was measured in pre- and post-measurements during single leg squats using Kinect Azure camera with DynaKnee software. In addition, maximal voluntary muscle contraction (MVC) was measured using a dynamometer and muscle activation amplitude (MAA) was measured using electromyography. Data were analysed using a non-parametric Wilcoxon signed rank test to assess differences in DKV, MAA and MVC at a 5% significance level. Data showed a small improvement of DKV in the dominant leg. MVC increased slightly in all variables. The MAA of the involved muscles in the single-leg squat did not show a higher value, but rather a decreasing trend. However, none of the analyses showed significant changes. The small number of participants and the short duration of the training might have been a limiting factor. Further studies should repeat the procedure with a larger group of participants and a longer training period.<\/jats:p>","DOI":"10.70252\/iimq1487","type":"journal-article","created":{"date-parts":[[2025,6,11]],"date-time":"2025-06-11T13:16:03Z","timestamp":1749647763000},"page":"561-574","source":"Crossref","is-referenced-by-count":1,"title":["The Effect of Functional Training on Dynamic Knee Valgus of Youth Soccer Players: A Pilot Study"],"prefix":"10.70252","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-3979-201X","authenticated-orcid":false,"given":"Ole","family":"Tovar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D\u00f3ra","family":"Moln\u00e1r","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3281-281X","authenticated-orcid":false,"given":"Badis","family":"Soussi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7337-8296","authenticated-orcid":false,"given":"\u00c1d\u00e1m","family":"Uhl\u00e1r","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3038-8643","authenticated-orcid":false,"given":"Tam\u00e1s","family":"Horv\u00e1th","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0409-0755","authenticated-orcid":false,"given":"Mira","family":"Ambrus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56809","published-online":{"date-parts":[[2025]]},"container-title":["International Journal of Exercise Science"],"original-title":[],"link":[{"URL":"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12289232\/pdf\/ijes-18-7-561.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T04:13:07Z","timestamp":1785989587000},"score":1,"resource":{"primary":{"URL":"https:\/\/digitalcommons.wku.edu\/ijes\/vol18\/iss7\/6\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.70252\/iimq1487","relation":{},"ISSN":["1939-795X"],"issn-type":[{"value":"1939-795X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025]]}}}
