Abstract

Our objective was to systematically review the literature and metaanalyse the effect of repeatedsprint training on a selection of fieldbased measures of athletic performance ie countermovement jump 10 m sprint 20 m sprint 30 m sprint repeatedsprint ability and highintensity intermittent running performanceThe SPORTDiscus PubMed MEDLINE and Web of Science databases were searched for original research articles Search terms included ‘repeatedsprint training’ ‘sprint training’ ‘aerobic endurance’ ‘repeatedsprint ability’ ‘countermovement jump’ and ‘sprint performance’Inclusion criteria included intervention consisting of a series of ≤10 s sprints with ≤60 s recovery trained participants intervention duration of 2–12 weeks fieldbased fitness measures running or cyclingbased intervention published up to and including February 2014Our final dataset included six trials for countermovement jump two controlled trials eight trials for 10 m sprint four trials for 20 m sprint three controlled trials two trials for 30 m sprint eight trials for repeatedsprint ability and three trials for highintensity intermittent running performance Analyses were conducted using comprehensive metaanalysis software Uncertainty in the metaanalysed effect of repeatedsprint training was expressed as 95  confidence limits CL along with the probability that the true value of the effect was trivial beneficial or harmful Magnitudebased inferences were based on standardised thresholds for small moderate and large changes of 02 06 and 12 standard deviations respectivelyRepeatedsprint training had a likely small beneficial effect in noncontrolled countermovement jump trials effect size 033 95  CL ±030 with a possibly moderate beneficial effect in controlled trials 063 95  CL ±044 There was a very likely small beneficial effect on 10 m sprint time in noncontrolled trials −042 95  CL ±024 with a possibly moderate beneficial effect on 20 m sprint time in noncontrolled −049 95  CL ±046 and controlled −065 95  CL ±061 trials Repeatedsprint training had a possibly large beneficial effect on 30 m sprint performance in noncontrolled trials −101 95  CL ±093 with possibly moderate beneficial effects on repeatedsprint ability −062 95  CL ±025 and highintensity intermittent running performance −061 95  CL ±054
