Standardized anthropometric, physical, and performance assessment tests included players\u2019 body mass and height, push up and pull-up test, squat test, sit-and-reach test, 20 m shuttle run test, flexed arm hang test, Sargent test, handgrip strength test, Illinois agility test, and 20-m and 50-m sprint test. Results showed that recruited forwards players had better agility scores (p = 0.02, ES = \u22120.55) than the non-recruited forwards, whereas recruited backs players had higher right (p &lt; 0.01, ES = 0.84) and left (p = 0.01, ES = 0.74) handgrip strength scores than their counterparts. Logistic regression showed that better agility (for the forwards) and right handgrip strength scores (for the backs) were the only variables significantly associated with an increased likelihood of being recruited to the national team. In sum, these findings suggest that certain well-developed physical qualities, namely, agility for the forwards players and upper-body strength for the back players, partially explain the selection of U19 rugby players to their national team.<\/jats:p>","DOI":"10.3390\/ijerph18041499","type":"journal-article","created":{"date-parts":[[2021,2,5]],"date-time":"2021-02-05T00:54:35Z","timestamp":1612486475000},"page":"1499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Using Anthropometric Data and Physical Fitness Scores to Predict Selection in a National U19 Rugby Union Team"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0484-7869","authenticated-orcid":false,"given":"Luis","family":"Vaz","sequence":"first","affiliation":[{"name":"Department of Sport Science, Exercise and Health, School of Life and Environmental Sciences, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"},{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development (CIDESD), 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8233-2839","authenticated-orcid":false,"given":"Wilbur","family":"Kraak","sequence":"additional","affiliation":[{"name":"Department of Sport Science, Faculty of Medicine and Health Sciences, Stellenbosch University, Stellenbosch 7600, South Africa"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3318-2472","authenticated-orcid":false,"given":"Marco","family":"Batista","sequence":"additional","affiliation":[{"name":"Department of Sports and Well-Being, Polytechnic Institute of Castelo Branco, SHERU (Sport, Health and Exercise Research Unit), 6000-084 Castelo Branco, Portugal"}]},{"given":"Samuel","family":"Hon\u00f3rio","sequence":"additional","affiliation":[{"name":"Department of Sports and Well-Being, Polytechnic Institute of Castelo Branco, SHERU (Sport, Health and Exercise Research Unit), 6000-084 Castelo Branco, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8667-4871","authenticated-orcid":false,"given":"H\u00e9lder","family":"Miguel Fernandes","sequence":"additional","affiliation":[{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development (CIDESD), 5000-801 Vila Real, Portugal"},{"name":"Research in Education and Community Intervention, RECI, 3500 Viseu, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"973","DOI":"10.2165\/00007256-200333130-00003","article-title":"Applied physiology and game analysis of rugby union","volume":"33","author":"Duthie","year":"2003","journal-title":"Sports Med."},{"key":"ref_2","first-page":"109","article-title":"Talent identification and development in youth rugby players: A research review","volume":"31","author":"Spamer","year":"2009","journal-title":"S.
