RoB: Risk of bias; Incon: Inconsistency; Indirect: Indirectness; Impre: Imprecision; PubB: Publication bias; Exp: Experimental; VJ= Vertical Jump; SPRINT-P= Sprint Performance; RSI=Reactive strength index; SLJ=Stand long jump; CI: Confidence interval, SMD: Standardized mean difference; According to Cohen'd regulations on effect sizes(Brydges, 2019), SMD=0.2 was set as the minimum clinically important difference (MICD), SMD≥0.8 as a large effect size; a: Risk of bias for included studies, more than 1/3 for some concerns or high risk of bias; b: Risk of bias for included studies, more than 1/2 for some concerns or High risk of bias; c: Heterogeneity assessment I2 ≥ 50%; d: Heterogeneity assessment I2 ≥75%; e: Heterogeneity between subjects, measures and interventions; f: MCID included in the 95% CI portion of the effect size; g: 95% CI of the effect size fully incorporates the MCID. |
