In a cross\u2010sectional controlled mixed model design, we compared dual\n X<\/jats:styled-content>\n \u2010ray absorptiometry\u2010derived bone mineral density (\n BMD<\/jats:styled-content>\n ) and bone size in 193 active and retired male elite soccer players and 280 controls, with duplicate measurements of the same individual done a mean 5 years apart. To evaluate lifetime fractures, we used a retrospective controlled study design in 397 retired male elite soccer players and 1368 controls. Differences in bone traits were evaluated by\n S<\/jats:styled-content>\n tudent's\n t<\/jats:italic>\n \u2010test and fracture risk assessments by\n P<\/jats:styled-content>\n oisson regression and\n C<\/jats:styled-content>\n ox regression. More than 30 years after retirement from sports, the soccer players had a\n \n Z<\/jats:italic>\n <\/jats:styled-content>\n \u2010score for total body\n BMD<\/jats:styled-content>\n of 0.4 (0.1 to 0.6), leg\n BMD<\/jats:styled-content>\n of 0.5 (0.2 to 0.8), and femoral neck area of 0.3 (0.0 to 0.5). The rate ratio for fracture after career end was 0.6 (0.4 to 0.9) and for any fragility fracture 0.4 (0.2 to 0.9). Exercise\u2010associated bone trait benefits are found long term after retirement from sports together with a lower fracture risk. This indicates that physical activity in youth could reduce the burden of fragility fractures.\n <\/jats:p>","DOI":"10.1111\/sms.12305","type":"journal-article","created":{"date-parts":[[2014,8,11]],"date-time":"2014-08-11T09:19:09Z","timestamp":1407748749000},"page":"453-461","source":"Crossref","is-referenced-by-count":43,"title":["Exercise in youth: High bone mass, large bone size, and low fracture risk in old age"],"prefix":"10.1111","volume":"25","author":[{"given":"M.","family":"Tveit","sequence":"first","affiliation":[{"name":"Clinical and Molecular Osteoporosis Research Unit Department of Orthopaedics and Clinical Sciences Sk\u00e5ne University Hospital, Lund University Malm\u00f6 Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.
