Twenty players aged 22.3 \u00b1 4.2 yr performed\"The 11+\" 3 times a week for 10 weeks. Isokinetic measurements were performed on the hamstrings and quadriceps muscles on both lower extremities at concentric 60 and 180\u00b0\/s and eccentric 30\u00b0\/s. The peak torque (PT) as well as conventional and dynamic control ratios (DCR) were calculated. Hamstrings PT in the non-dominant limb increased by 14.6%, 15.0% and 14.3% during the above contractions\/velocities, respectively (p&lt; 0.05). In the dominant limb the concentric PT of the quadriceps increased by 6.9% (60\u00b0\/s) and 8.3% (180\u00b0\/s) whereas that of the hamstring increased by 20.4%(60\u00b0\/s), (p&lt; 0.05). The training programme significantly improved the conventional H\/Q ratio at 60\u00b0\/s by 14.8{\\%} and the DCR by 13.8% in the non-dominant limb (p&lt; 0.05). Therefore, the \"The 11+\" training programme appears to be adequate and effective for soccer training and conditioning by improving strength and muscle balance around the knee joint.<\/jats:p>","DOI":"10.3233\/ies-2010-0386","type":"journal-article","created":{"date-parts":[[2018,10,30]],"date-time":"2018-10-30T10:50:30Z","timestamp":1540896630000},"page":"211-215","source":"Crossref","is-referenced-by-count":66,"title":["Isokinetic strength effects of FIFA's \"The 11+\" injury prevention training programme"],"prefix":"10.1177","volume":"18","author":[{"given":"Jo\u00e3o","family":"Brito","sequence":"first","affiliation":[{"name":"Centre of Research, Education, Innovation and Intervention in Sport, Faculty of Sport of the University of Porto, Portugal"}]},{"given":"Pedro","family":"Figueiredo","sequence":"additional","affiliation":[{"name":"Centre of Research, Education, Innovation and Intervention in Sport, Faculty of Sport of the University of Porto, Portugal"}]},{"given":"Lu\u00eds","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Centre of Research, Education, Innovation and Intervention in Sport, Faculty of Sport of the University of Porto, Portugal"}]},{"given":"Andr\u00e9","family":"Seabra","sequence":"additional","affiliation":[{"name":"Centre of Research, Education, Innovation and Intervention in Sport, Faculty of Sport of the University of Porto, Portugal"}]},{"given":"Jos\u00e9 M.","family":"Soares","sequence":"additional","affiliation":[{"name":"Centre of Research, Education, Innovation and Intervention in Sport, Faculty of Sport of the University of Porto, Portugal"}]},{"given":"Peter","family":"Krustrup","sequence":"additional","affiliation":[{"name":"Centre of Research, Education, Innovation and Intervention in Sport, Faculty of Sport of the University of Porto, Portugal"}]},{"given":"Ant\u00f3nio","family":"Rebelo","sequence":"additional","affiliation":[{"name":"Centre of Research, Education, Innovation and Intervention in Sport, Faculty of Sport of the University of Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2010,11,1]]},"container-title":["Isokinetics and Exercise Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/IES-2010-0386","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/IES-2010-0386","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T11:49:32Z","timestamp":1777463372000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/IES-2010-0386"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,11]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2010,11]]}},"alternative-id":["10.3233\/IES-2010-0386"],"URL":"https:\/\/doi.org\/10.3233\/ies-2010-0386","relation":{},"ISSN":["0959-3020","1878-5913"],"issn-type":[{"value":"0959-3020","type":"print"},{"value":"1878-5913","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,11]]}}}
