The effects of high-intensity interval training on cognitive performance: a systematic review and meta-analysis

Cognitive decline is an important feature of an aging population. Despite the large body of research investigating the effects of high-intensity interval training (HIIT) on cognitive performance, reports of its effectiveness are inconsistent and it is difficult to determine what factors moderate the...

Description
Summary:Cognitive decline is an important feature of an aging population. Despite the large body of research investigating the effects of high-intensity interval training (HIIT) on cognitive performance, reports of its effectiveness are inconsistent and it is difficult to determine what factors moderate these effects. The purpose of this study was to conduct a meta-analysis of existing randomised controlled trials investigating the effects of HIIT on various domains of cognitive performance, and to further examine the intervention cycle and age-related moderating effects. A comprehensive literature search was conducted across a range of databases, including PubMed, Embase, the Cochrane Library, Web of Science, Scopus, and EBSCO. The meta-analysis included data from 20 RCT studies. The results of the analyses demonstrated that HIIT significantly enhanced information processing (SMD = 0.33, 95% CI: 0.15–0.52, P  = 0.0005), executive function (SMD = 0.38, 95% CI: 0.26 – 0.50, P
