Eight boys (15.1\u00b10.4 y) completed three 3-day experimental trials in a randomised order: 1) 8\u00d71\u2009min cycling at 90% peak power with 75\u2009s recovery (HIIE); 2) cycling at 90% of gas exchange threshold for a duration to match work during HIIE (MIE); and 3) rest (CON). Plasma [glucose] and [insulin] were measured before (PRE-Ex), 24 and 48\u2009h post (24\u2009h-POST, 48\u2009h-POST) in a fasted state, and 40\u2009min (POST-Ex) and 24\u2009h (24\u2009h-POST) post in response to an oral glucose tolerance test (OGTT). IS was estimated using the Cederholm (OGTT) and HOMA (fasted) indices. There was no change to HOMA at 24\u2009h or 48\u2009h-POST (all P&gt;0.05). IS from the OGTT was higher POST-EX for HIIE compared to CON (17.4%, P=0.010, ES=1.06), and a non-significant increase in IS after MIE compared to CON (9.0%, P=0.14, ES=0.59). At 24\u2009h-POST, IS was higher following both HIIE and MIE compared to CON (HIIE: P=0.019, 13.2%, ES=0.88; MIE: 9.7%, P=0.024, ES=0.65). In conclusion, improvements to IS after a single bout of HIIE and MIE persist up to 24\u2009h after exercise when assessed by OGTT.<\/jats:p>","DOI":"10.1055\/s-0043-118007","type":"journal-article","created":{"date-parts":[[2017,10,1]],"date-time":"2017-10-01T18:30:40Z","timestamp":1506882640000},"page":"967-974","source":"Crossref","is-referenced-by-count":18,"title":["Acute Exercise and Insulin Sensitivity in Boys: A Time-Course Study"],"prefix":"10.1055","volume":"38","author":[{"given":"Emma","family":"Cockcroft","sequence":"additional","affiliation":[{"name":"Children's Health and Exercise Research Centre, Sport and Health Sciences, University of Exeter, Exeter, United Kingdom"},{"name":"Exeter Medical School, University of Exeter, Exeter, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig","family":"Williams","sequence":"additional","affiliation":[{"name":"Children's Health and Exercise Research Centre, Sport and Health Sciences, University of Exeter, Exeter, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hayley","family":"Weaver","sequence":"additional","affiliation":[{"name":"Sport and Health Sciences, University of Exeter, Exeter, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"O'Connor","sequence":"additional","affiliation":[{"name":"Children's Health and Exercise Research Centre, Sport and Health Sciences, University of Exeter, Exeter, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Jackman","sequence":"additional","affiliation":[{"name":"Sport and Health Sciences, University of Exeter, Exeter, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neil","family":"Armstrong","sequence":"additional","affiliation":[{"name":"Children's Health and Exercise Research Centre, Sport and Health Sciences, University of Exeter, Exeter, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan","family":"Barker","sequence":"additional","affiliation":[{"name":"Children's Health and Exercise Research Centre, Sport and Health Sciences, University of Exeter, Exeter, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2017,10,1]]},"container-title":["International Journal of Sports Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0043-118007.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,12,20]],"date-time":"2017-12-20T01:56:58Z","timestamp":1513735018000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0043-118007"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,10,1]]},"references-count":0,"journal-issue":{"issue":"13","published-online":{"date-parts":[[2017,11,30]]},"published-print":{"date-parts":[[2017,11]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0043-118007","relation":{},"ISSN":["0172-4622","1439-3964"],"issn-type":[{"value":"0172-4622","type":"print"},{"value":"1439-3964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,10,1]]}}}
