Abstract

OBJECTIVE: To address the rapid influence of testosterone (T) on neuromuscular performance, we compared the T and physical performance responses of adults exposed to a physical and psychological stimulus. DESIGN: A group of healthy men (n=12) and women (n=14) each completed three treatments using a...

DESIGN: A group of healthy men (n=12) and women (n=14) each completed three treatments using a randomised, crossover design: exercise involving five &#xD7; ten-second cycle sprints, viewing a video clip with aggressive content and a control session. Salivary T concentrations, hand-grip strength (HGS) and countermovement jump peak power (CMJ PP) were assessed before and 15 minutes after each session. RESULTS: The relative changes in T (17&#xB1;29%) and CMJ PP (-0.1&#xB1;4.4%) following sprint exercise were superior to the aggressive video (-6.3&#xB1;19%, -2.2&#xB1;5.9%) and control (-4.8&#xB1;23%, -2.8&#xB1;4.4%) treatments, respectively (p &#x2264;0.05). Pre-treatment T levels correlated (r= -0.58 to -0.61, p &lt;0.05) with the T responses of men (sprint exercise) and women (sprint exercise, aggressive video), but no variables were significantly correlated with the relative changes in HGS or CMJ PP. CONCLUSIONS: Sprint exercise promoted a general rise in T and maintained CMJ PP, relative to the video and control treatments. In both sexes, those individuals with higher pre-test T levels tended to produce smaller T responses to one or more treatments. These data highlight the importance of stimulus selection and individual predispositions when attempting to acutely modify T and associated physical performance.</abstract><type>Journal Article</type><journal>HORMONES</journal><volume>15</volume><journalNumber>2</journalNumber><paginationStart>248</paginationStart><paginationEnd>255</paginationEnd><publisher/><issnPrint>1109-3099</issnPrint><keywords/><publishedDay>31</publishedDay><publishedMonth>12</publishedMonth><publishedYear>2016</publishedYear><publishedDate>2016-12-31</publishedDate><doi>10.14310/horm.2002.1676</doi><url/><notes/><college>COLLEGE NANME</college><department>Engineering and Applied Sciences School</department><CollegeCode>COLLEGE CODE</CollegeCode><DepartmentCode>EAAS</DepartmentCode><institution>Swansea University</institution><apcterm/><lastEdited>2017-08-03T13:43:24.5030085</lastEdited><Created>2016-05-30T11:08:28.1137112</Created><path><level id="1">Faculty of Science and Engineering</level><level id="2">School of Aerospace, Civil, Electrical, General and Mechanical Engineering - Sport and Exercise Sciences</level></path><authors><author><firstname>Blair</firstname><surname>Crewther</surname><order>1</order></author><author><firstname>Liam</firstname><surname>Kilduff</surname><orcid>0000-0001-9449-2293</orcid><order>2</order></author><author><firstname>Charlie</firstname><surname>Finn</surname><order>3</order></author><author><firstname>Phil</firstname><surname>Scott</surname><order>4</order></author><author><firstname>Christian</firstname><surname>Cook</surname><order>5</order></author></authors><documents><document><filename>0028393-04082016104515.pdf</filename><originalFilename>crewther2016v2.pdf</originalFilename><uploaded>2016-08-04T10:45:15.8130000</uploaded><type>Output</type><contentLength>357421</contentLength><contentType>application/pdf</contentType><version>Version of Record</version><cronfaStatus>true</cronfaStatus><embargoDate>2016-08-04T00:00:00.0000000</embargoDate><documentNotes>Publisher pdf</documentNotes><copyrightCorrect>false</copyrightCorrect></document></documents><OutputDurs/></rfc1807>
