Abstract

Purpose: Recent meta-analyses indicate that sprint interval training (SIT) improves cardiorespiratory fitness (V˙ O2max), but the effects of various training parameters on the magnitude of the improvement remain unknown. The present meta-analysis examined the modifying effect of the number of sprint...

Methods: The databases PubMed and Web of Science were searched for original studies that have examined pre- and posttraining V&#x2D9; O2max in adults after Q2 wk of training consisting of repeated (Q2) Wingate-type cycle sprints, published up to May 1, 2016.

Results: The meta-analysis revealed a likely large effect of a typical SIT intervention on V&#x2D9; O2max (mean T 90% confidence limits = 7.8% T 4.0%) with a possibly small modifying effect of the maximum number of sprint repetitions in a training session (j1.2% T 0.8% decrease per two additional sprint repetitions). Apart from possibly small effects of baseline V&#x2D9; O2max and age, all other modifying effects were unclear or trivial. Conclusion: We conclude that the improvement in V&#x2D9; O2max with SIT is not attenuated with fewer sprint repetitions, and possibly even enhanced. This means that SIT protocols can be made more time efficient, which may help SIT to be developed into a viable strategy to impact public health.</abstract><type>Journal Article</type><journal>Medicine &amp; Science in Sports &amp; Exercise</journal><volume>49</volume><journalNumber>6</journalNumber><paginationStart>1147</paginationStart><paginationEnd>1156</paginationEnd><publisher>Ovid Technologies (Wolters Kluwer Health)</publisher><placeOfPublication/><isbnPrint/><isbnElectronic/><issnPrint>0195-9131</issnPrint><issnElectronic/><keywords>SYSTEMATIC REVIEW, CARDIORESPIRATORY FITNESS, AEROBIC CAPACITY, SPRINT INTERVAL TRAINING</keywords><publishedDay>1</publishedDay><publishedMonth>6</publishedMonth><publishedYear>2017</publishedYear><publishedDate>2017-06-01</publishedDate><doi>10.1249/mss.0000000000001204</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>2020-11-24T21:09:48.7210645</lastEdited><Created>2017-09-26T13:26:01.1216293</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>NIELS B.
