Abstract

Introduction: Digit ratio (2D:4D: the relative length of the 2nd and 4th digit)is thought to be a negative correlate of prenatal testosterone. The 2D:4D is related to oxygen metabolism, but the precise nature of this relationship is unclear. The purpose of the present study was to consider associati...

The purpose of the present study was to consider associations between digit ratios (right 2D:4D, left 2D:4D, right–left 2D:4D [Dr-l]) and VO2max and ventilatory thresholds (VT1 and VT2). Methods: One hundred and thirty-three Caucasian (n = 133) professional football players competing in Cyprus participated in the study. Players underwent anthropometric measurements, and digit lengths were measured from hand scans. They also completed an incremental cardiopulmonary test to exhaustion on a treadmill. Results: There were negative correlations between digit ratios and VO2max (right 2D:4D, r = −.65; left 2D:4D r = −.37, both p &lt; .0001; Dr-l r = −.30, p = .0005). There were no relationships between digit ratios and VT1. For VT2, there were negative relationships with digit ratios (right 2D:4D, r = −.43, p &lt; .0001; left 2D:4D, r = −.21 and Dr-l, r = −.21, both p = .02). Digit ratios are negatively related to VO2max with large (right 2D:4D) and medium (left2D:4D, Dr-l) effect sizes. For VT2, there were also negative correlations, which were medium (right 2D:4D) and small (left 2D:4D, Dr-l). Conclusion: Our findings may help clarify the relationships between digit ratios and high-intensity actions for extended periods, which are dependent on efficient oxygen metabolism.</abstract><type>Journal Article</type><journal>American Journal of Human Biology</journal><volume>36</volume><journalNumber>6</journalNumber><paginationStart/><paginationEnd/><publisher>Wiley</publisher><placeOfPublication/><isbnPrint/><isbnElectronic/><issnPrint>1042-0533</issnPrint><issnElectronic>1520-6300</issnElectronic><keywords/><publishedDay>1</publishedDay><publishedMonth>6</publishedMonth><publishedYear>2024</publishedYear><publishedDate>2024-06-01</publishedDate><doi>10.1002/ajhb.24047</doi><url/><notes/><college>COLLEGE NANME</college><CollegeCode>COLLEGE CODE</CollegeCode><institution>Swansea University</institution><apcterm>Not Required</apcterm><funders/><projectreference/><lastEdited>2024-10-03T11:28:06.2063805</lastEdited><Created>2024-02-05T12:35:58.7825389</Created><path><level id="1">Faculty of Science and Engineering</level><level id="2">School of Engineering and Applied Sciences - Sport and Exercise Sciences</level></path><authors><author><firstname>Koulla</firstname><surname>Parpa</surname><orcid>0000-0002-1139-7731</orcid><order>1</order></author><author><firstname>John</firstname><surname>Manning</surname><order>2</order></author><author><firstname>Magdalena</firstname><surname>Kobus</surname><order>3</order></author><author><firstname>Laura</firstname><surname>Mason</surname><orcid>0000-0002-9679-7063</orcid><order>4</order></author><author><firstname>Marcos</firstname><surname>Michaelides</surname><order>5</order></author></authors><documents><document><filename>65570__29947__12d8203e5614436e817fae2f8cf8b401.pdf</filename><originalFilename>65570.AAM.pdf</originalFilename><uploaded>2024-04-08T12:37:24.1850084</uploaded><type>Output</type><contentLength>132379</contentLength><contentType>application/pdf</contentType><version>Accepted Manuscript</version><cronfaStatus>true</cronfaStatus><documentNotes>Author accepted manuscript document released under the terms of a Creative Commons CC-BY licence using the Swansea University Research Publications Policy (rights retention).</documentNotes><copyrightCorrect>true</copyrightCorrect><language>eng</language><licence>https://creativecommons.org/licenses/by/4.0/</licence></document></documents><OutputDurs/></rfc1807>
