Abstract

The purpose of this meta-analytic review was to examine the extent and quality of research on the post-activation potentiation acute effect of rest interval manipulation on jumping performance. This manuscript adopted the recommendations from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement. Criteria eligibility included crossover, randomised, non-randomised and counterbalanced studies that observed the voluntary muscle action-induced postactivation potentiation on jumping performance. Fourteen studies selected by two independent raters were included in the analysis. The rest intervals involved ranges including 0–3, 4–7, 8–12 and ≥ 16 min. The results demonstrated medium effect sizes for rest intervals 0–3 and 8–12 min (-0.25, Confidence Interval (CI): -0.51 to 0.01 for 0–3 min; 0.24, CI: -0.02 to 0.49 for 8–12 min) and a small effect for other ranges (0.15, CI: -0.08 to 0.38 for 4–7 min; 0.07, CI: -0.21 to 0.24 for ≥ 16 min). There was no evidence of heterogeneity for sub-groups (I2 = 0%; P<0.001) and no indication of publication bias (Egger’s test, P=0.179). While a rest interval of 0–3 min induced a detrimental effect on jump performance, the range including 8– 12 min had a beneficial impact on jump height. Findings suggest that the rest interval manipulation seems to affect postactivation potentiation magnitude and jump height. Verf.-Referat
