Abbreviations: SJ: squat jump; * means and standard deviation; † compared to pretreatment; ‡ mean difference (95% confidence interval); ~ statistically significant differences (p < 0.05); η2 = Eta squared. Effect Size; %RC = percentage relative change = (V1–V2)/V2 × 100. Bold: refers to another analysis.
