(1) The posttest was assessed after 4 weeks of supplementation. (2) The main effect of supplementation (sup) refers to the NCE and placebo treatment and the main effect of time is the distance recorded at 2 points (pre- and post-). Data are presented as the mean ± SEM for n=6 in each group. Statistical analysis was using a Two-Way ANOVA. A p value <0.05 was considered significantly different. The post-hoc test was performed by repeated Student’s t-test between groups at the same time point and significance () set at an alpha level of 0.05. Drop jumps high (DJH); reactive strength index (RSI); peak vertical ground reaction force (PVGRF).
