Quantification of the relative age effect in three indices of physical performance. J Strength Cond Res 27(12): 3293–3299, 2013—The relative age effect (RAE) describes the relationship between an individual’s birth month and their level of attainment in sports. There is a clustering of birth dates just after the cutoff used for selection in age-grouped sports, and it is hypothesized that such relatively older sportspeople may enjoy maturational and physical advantages over their younger peers. There is, however, little empirical evidence of any such advantage. This study investigated whether schoolchildren’s physical performance differed according to which quarter of the school year they were born in. Mass, stature, body mass index, cardiorespiratory fitness, strength, and power were measured in 10 to 16 year olds (n = 8,550, 53% male). We expressed test performance as ageand sex-specific z-scores based on reference data with age rounded down to the nearest whole year and also as units normalized for body mass. We then compared these values between yearly birth quarters. There were no significant main effects for differences in anthropometric measures in either sex. Girls born in the first quarter of the school year were significantly stronger than those born at other times when handgrip was expressed as a zscore. As z-scores, all measures were significantly higher in boys born in either the first or second yearly quarters. Relative to body mass, cardiorespiratory fitness was higher in boys born in the first quarter and power was higher in those born in the second quarter. The RAE does not appear to significantly affect girls’ performance test scores when they are expressed as z-score or relative to body mass. Boys born in the first and second quarters of the year had a significant physical advantage over their relatively younger peers. These findings have practical bearing if coaches use fitness tests for talent identification and team selection. Categorizing test per formance based on rounded down values of whole-year age may disadvantage children born later in the selection year. These relatively younger children may be less to gain selection for teams or training programmes.application/pdf10.1519/JSC.0b013e318291b28d1533-42871064-8011https://repositorio.udes.edu.co/handle/001/3569engJournal of Strength and Conditioning ResearchDerechos Reservados - Journal of Strength and Conditioning Research, 2013info:eu-repo/semantics/closedAccessAtribución-NoComercial 4.0 Internacional (CC BY-NC 4.0)https://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_14cbhttp://ovidsp.dc2.ovid.com/sp-4.01.0a/ovidweb.cgi?WebLinkFrameset=1&S=JMHAFPDEGPEBCLFEJPCKFFBHHCENAA00&returnUrl=ovidweb.cgi%3f%26Complete%2bReference%3dS.sh.24%257c1%257c1%26FORMAT%3dcitationFormatPrint%26FIELDS%3dFORMATl%26S%3dJMHAFPDEGPEBCLFEJPCKFFBHHCENAA00&directlink=http%3a%2f%2fovidsp.dc2.ovid.com%2fovftpdfs%2fFPEBJPBHFFFEGP00%2ffs047%2fovft%2flive%2fgv031%2f00124278%2f00124278-201312000-00009.pdf&filename=Quantification+of+the+Relative+Age+Effect+in+Three+Indices+of+Physical+Performance.&navigation_links=NavLinks.S.sh.24.1&PDFIdLinkField=%2ffs047%2fovft%2flive%2fgv031%2f00124278%2f00124278-201312000-00009&link_from=S.sh.24%7c1&pdf_key=B&pdf_index=S.sh.24&D=ovftAgeingChildren and adolescentsPhysical fitnessQuantification of the relative age effect in three indices of physical performanceArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85PublicationTHUMBNAILQuantification of the relative age effect in three indices of physical performance.pdf.jpgQuantification of the relative age effect in three indices of physical performance.pdf.jpgGenerated Thumbnailimage/jpeg1815https://repositorio.udes.edu.co/bitstreams/3a513432-d00a-4914-8748-2eb4b5e76ca3/download03d29570105cf1560d31172228886dd5MD54TEXTQuantification of the relative age effect in three indices of physical performance.pdf.txtQuantification of the relative age effect in three indices of physical performance.pdf.txtExtracted texttext/plain36155https://repositorio.udes.edu.co/bitstreams/2f578d2b-1d2a-4789-9f86-ee47884a6e45/download7429f9da549f5b9c27d5b33f7f9d65d9MD53LICENSElicense.txtlicense.txttext/plain; charset=utf-859https://repositorio.udes.edu.co/bitstreams/555d4b4f-5a2f-4f23-8ab4-2434ab198f68/download38d94cf55aa1bf2dac1a736ac45c881cMD52ORIGINALQuantification of the relative age effect in three indices of physical performance.pdfQuantification of the relative age effect in three indices of physical performance.pdfapplication/pdf162010https://repositorio.udes.edu.co/bitstreams/044fabc5-ecf6-4787-b076-255785711d43/downloadaa3f6c2a0f4b1bad55900e845c89be09MD55001/3569oai:repositorio.udes.edu.co:001/35692023-10-10 08:34:49.181https://creativecommons.org/licenses/by-nc/4.0/Derechos Reservados - Journal of Strength and Conditioning Research, 2013https://repositorio.udes.edu.coRepositorio Universidad de Santandersoporte@metabiblioteca.comTGljZW5jaWEgZGUgUHVibGljYWNpw7NuIFVERVMKRGlyZWN0cmljZXMgZGUgVVNPIHkgQUNDRVNPCgo=
