A positive correlation would indicate that the CR could predict DCR.<\/jats:p>\n                  <jats:p>METHODS: One hundred and thirteen Brazilian elite soccer players (25.2 \u00b1 5.3 yrs) performed maximal dominant and nondominant knee concentric (CON) and eccentric(ECC) strength tests at 60\u00b0\/s on an isokinetic dynamometer in order to calculate CR and DCR.<\/jats:p>\n                  <jats:p>RESULTS: A significant positive correlation between ratios was found for the dominant and non-dominant knees (r=0.54 and 0.62; p &lt; 0.001 which translated into low $R^{2}$ values of 0.29 and 0.39, respectively.<\/jats:p>\n                  <jats:p>CONCLUSION: This suggests that the CR may not replace the DCR and is thus of a limited clinical value in assessing knee muscles imbalance. On the other hand, the paper presents for the first time a robust reference frame for the isokinetic strength and related ratios of the two major knee muscles in soccer players.<\/jats:p>","DOI":"10.3233\/ies-140557","type":"journal-article","created":{"date-parts":[[2018,10,30]],"date-time":"2018-10-30T11:44:51Z","timestamp":1540899891000},"page":"1-12","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":16,"title":["The association between conventional and dynamic control knee strength ratios in elite soccer players"],"prefix":"10.1177","volume":"23","author":[{"given":"Cassio V.","family":"Ruas","sequence":"first","affiliation":[{"name":"Physical Education School, Federal University of Rio Grande do Sul, Porto Alegre, Brazil"}]},{"given":"Matheus D.","family":"Pinto","sequence":"additional","affiliation":[{"name":"Physical Education School, Federal University of Rio Grande do Sul, Porto Alegre, Brazil"}]},{"given":"Lee E.","family":"Brown","sequence":"additional","affiliation":[{"name":"Physical Education School, Federal University of Rio Grande do Sul, Porto Alegre, Brazil"}]},{"given":"Felipe","family":"Minozzo","sequence":"additional","affiliation":[{"name":"Physical Education School, Federal University of Rio Grande do Sul, Porto Alegre, Brazil"}]},{"given":"Pedro","family":"Mil-Homens","sequence":"additional","affiliation":[{"name":"Physical Education School, Federal University of Rio Grande do Sul, Porto Alegre, Brazil"}]},{"given":"Ronei S.","family":"Pinto","sequence":"additional","affiliation":[{"name":"Physical Education School, Federal University of Rio Grande do Sul, Porto Alegre, Brazil"}]}],"member":"179","published-online":{"date-parts":[[2015,2,1]]},"container-title":["Isokinetics and Exercise Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/IES-140557","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/IES-140557","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T11:50:16Z","timestamp":1777463416000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/IES-140557"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,2]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2015,2]]}},"alternative-id":["10.3233\/IES-140557"],"URL":"https:\/\/doi.org\/10.3233\/ies-140557","relation":{},"ISSN":["0959-3020","1878-5913"],"issn-type":[{"value":"0959-3020","type":"print"},{"value":"1878-5913","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,2]]}}}
