Eight male players (age 17 \u00b1 2 years) of the Puerto Rican Olympic Team recorded daily activities and food intake over 12 days. Daily energy expenditure was 3,833 \u00b1 571 (SD) kcal, and energy intake was 3,952 \u00b1 1,071 kcal, of which 53.2 \u00b1 6.2% (8.3 g \u22c5 kg BW<jats:sup>\u22121<\/jats:sup>) was from carbohydrates (CHO), 32.4 \u00b1 4.0% from fat, and 14.4 \u00b1 2.3% from protein. With the exception of calcium, all micronutrients examined were in accordance with dietary guidelines. Body fat was 7.6 \u00b1 1.1% of body weight. Time to completion of three runs of the soccer-specific test was 37.65 \u00b1 0.62 s, and peak torques of the knee flexors and extensors at 60\u00b0 \u22c5 s<jats:sup>\u22121<\/jats:sup> were 139 \u00b1 6 and 225 \u00b1 9 N \u22c5 m, respectively. Players' absolute amounts of CHO seemed to be above the minimum recommended intake to maximize glycogen storage, but calcium intakes were below recommended. Their body fat was unremarkable, and they had a comparatively good capacity to endure repeated bouts of intense soccer-specific exercise and to exert force with their knee extensors and flexors.<\/jats:p>","DOI":"10.1123\/ijsn.8.3.230","type":"journal-article","created":{"date-parts":[[2016,8,10]],"date-time":"2016-08-10T12:07:13Z","timestamp":1470830833000},"page":"230-240","source":"Crossref","is-referenced-by-count":53,"title":["Dietary and Performance Assessment of Elite Soccer Players during a Period of Intense Training"],"prefix":"10.1123","volume":"8","author":[{"given":"Jes\u00das","family":"Rico-Sanz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walter R.","family":"Frontera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A.","family":"Mol\u00e9","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel A.","family":"Rivera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anita","family":"Rivera-Brown","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carol N.","family":"Meredith","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","container-title":["International Journal of Sport Nutrition"],"original-title":[],"link":[{"URL":"https:\/\/journals.humankinetics.com\/view\/journals\/ijsnem\/8\/3\/article-p230.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.humankinetics.com\/downloadpdf\/journals\/ijsnem\/8\/3\/article-p230.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/journals.humankinetics.com\/downloadpdf\/journals\/ijsnem\/8\/3\/article-p230.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T00:03:10Z","timestamp":1724284990000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.humankinetics.com\/view\/journals\/ijsnem\/8\/3\/article-p230.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,9]]},"references-count":0,"journal-issue":{"issue":"3"},"URL":"https:\/\/doi.org\/10.1123\/ijsn.8.3.230","relation":{},"ISSN":["1050-1606"],"issn-type":[{"value":"1050-1606","type":"print"}],"subject":[],"published":{"date-parts":[[1998,9]]}}}
