Acute Effect of a Conditioning Activity on Vertical Jump Height in Trained Adult Women: A Systematic Review with Meta-Analysis

Objective: To verify the acute effect of conditioning activity protocols on vertical jump height in trained women.Methods: A systematic review with meta-analysis was performed based on studies retrieved from Pubmed, SciELO, Scopus, SPORTDiscus, and Web of Science databases.The screening and eligibility of the studies were carried out by two independent evaluators and with a third researcher in case of disagreements.The result of the meta-analysis was obtained from the standardized mean difference (SMD), 95% confidence intervals (CI), and inconsistency test (I 2 ).Results: Five studies were included in the meta-analysis.The conditioning activity intervention generated higher jumping performances than the control group/session (SMD = 0.91 [95% CI: 0.57 -1.24]), but with high heterogeneity (I 2 = 75%).Subgroup analysis demonstrated that dynamic conditioning activities have better jump performance responses than isometrics.Conditioning activities with multiple sets increased jump performance more than single sets.Female athletes and those with more training experience appear more responsive to conditioning activity than females with lower training levels.Conclusion: A conditioning activity can improve the vertical jump's acute performance in trained women.Female athletes with more training experience seem more responsive to dynamic conditioning activity, with greater volume and intensities above 70% of 1RM.
