Abstract: Brink, NJ, Constantinou, D, and Torres, G. Postactivation performance enhancement in healthy adults using a bodyweight conditioning activity: a systematic review and meta-analysis. J Strength Cond Res 37(4): 930-937, 2023-A systematic review and meta-analysis were conducted to review the available evidence on whether a bodyweight conditioning activity can acutely improve the performance outcome of a subsequent task through postactivation performance enhancement. Data sources included PubMed (National Library of Medicine), Web of Science (Clarivate Analytics), Google Scholar, SPORTDiscuss (EBSCO), Embase (Elsevier), and Thesis Global. Subjects were healthy, active adults who performed either a vertical jump or a linear sprint outcome measurement. All studies were randomized controlled trials where the effects of a bodyweight conditioning activity were compared with a control condition. The control group followed the same course as the experimental group excluding the intervention, with the intervention and outcome measurement carried out in the same session. The intervention was completed before the initiation of the outcome measure testing. Nineteen studies fulfilled the eligibility criteria and were included. There was a small overall effect of 0.30 (95% confidence interval 0.14-0.46, p = 0.0003) in favor of using a bodyweight conditioning activity to improve the outcome of a subsequent vertical jump or linear sprint. Secondary analysis indicated that there was no difference between the vertical jump and sprint subgroup, <5 minutes or 5 minutes and greater between the intervention and outcome measurement subgroup, or whether an intervention with the same movements or different movements was used before the outcome task subgroup. Using bodyweight conditioning activities before performing a maximal vertical jump or sprint may provide a small benefit in performance outcome., (Copyright © 2022 National Strength and Conditioning Association.)
