Abstract

BackgroundAttenuating muscle damage is important to subsequent sports performance. It is possible that pre-exercise protein intake could influence markers of muscle damage and benefit performance, however, published research provides conflicting results. At present no study has investigated protein...

Blood glucose was also higher during and post-exercise following PRO/CHO (p&#x2009;&lt;&#x2009;0.050), as was free throw shooting accuracy in the fourth quarter (p&#x2009;=&#x2009;0.027).

However, unfamiliarity with the protein amount provided may have increased nausea during exercise, and this may have limited the ability to see an improvement in more performance measures.</abstract><type>Journal Article</type><journal>Journal of the International Society of Sports Nutrition</journal><volume>11</volume><journalNumber>1</journalNumber><paginationStart>33</paginationStart><publisher/><issnPrint>1550-2783</issnPrint><keywords/><publishedDay>25</publishedDay><publishedMonth>6</publishedMonth><publishedYear>2014</publishedYear><publishedDate>2014-06-25</publishedDate><doi>10.1186/1550-2783-11-33</doi><url/><notes/><college>COLLEGE NANME</college><department>Sport and Exercise Sciences</department><CollegeCode>COLLEGE CODE</CollegeCode><DepartmentCode>STSC</DepartmentCode><institution>Swansea University</institution><apcterm/><lastEdited>2017-07-10T16:08:15.4463137</lastEdited><Created>2015-04-10T10:47:57.0659552</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>Hannah</firstname><surname>Gentle</surname><order>1</order></author><author><firstname>Thomas</firstname><surname>Love</surname><order>2</order></author><author><firstname>Anna</firstname><surname>Howe</surname><order>3</order></author><author><firstname>Katherine</firstname><surname>Black</surname><order>4</order></author><author><firstname>Tom</firstname><surname>Love</surname><orcid>0000-0002-9404-5394</orcid><order>5</order></author></authors><documents><document><filename>0020613-01042016212909.pdf</filename><originalFilename>2.__Gentle__et__al__(2014)__(TL__submission).pdf</originalFilename><uploaded>2016-04-01T21:29:09.9270000</uploaded><type>Output</type><contentLength>340050</contentLength><contentType>application/pdf</contentType><version>Version of Record</version><cronfaStatus>true</cronfaStatus><embargoDate>2016-04-01T00:00:00.0000000</embargoDate><documentNotes>&#xA9; 2014 Gentle et al.; licensee BioMed Central Ltd.
