Thirty-seven pro fessional footballers from an Australian Football League team had preseason measurements of ham string and quadriceps muscle concentric peak torque at 60, 180, and 300 deg\/sec measured on a Cybex 340 dynamometer. Players were studied prospectively throughout the 1995 season. During that time, six play ers sustained clinically diagnosed hamstring muscle injuries that caused them to miss match-playing time. The injured hamstring muscles were all weaker than in the opposite leg in absolute values and hamstring-to- quadriceps muscle ratios. According to our t-test re sults, hamstring muscle injury was significantly asso ciated with a low hamstring-to-quadriceps muscle peak torque ratio at 60 deg\/sec on the injured side and a low hamstring muscle side-to-side peak torque ratio at 60 deg\/sec. Flexibility (as measured by the sit-and-reach test) did not correlate with injury. Discriminant-function analysis using the two significant ratio variables re sulted in a canonical correlation with injury of 0.4594 and correctly classified legs into injury groups with 77.4% success. These results indicate that preseason isokinetic testing of professional Australian Rules foot ballers can identify players at risk of developing ham string muscle strains.<\/jats:p>","DOI":"10.1177\/036354659702500116","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T20:46:52Z","timestamp":1182458812000},"page":"81-85","source":"Crossref","is-referenced-by-count":374,"title":["Preseason Hamstring Muscle Weakness Associated with Hamstring Muscle Injury in Australian Footballers"],"prefix":"10.1177","volume":"25","author":[{"given":"John","family":"Orchard","sequence":"first","affiliation":[{"name":"School of Physiology and Pharmacology, University of New South Wales, Sydney, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Marsden","sequence":"additional","affiliation":[{"name":"New South Wales Academy of Sport, Sydney, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Lord","sequence":"additional","affiliation":[{"name":"Prince of Wales Medical Research Institute, Sydney, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Garlick","sequence":"additional","affiliation":[{"name":"School of Physiology and Pharmacology, University of New South Wales, Sydney, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1997,1,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-1716.1995.tb09927.x"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1249\/00005768-197002010-00010"},{"key":"atypb3","unstructured":"Cowan D., Jones B., Tomlinson P., et al The epidemiology of physical training injuries in US Army infantry trainees.
