Power speed
The results of the respective two-way ANOVA conducted for the Broad Jump Test revealed significant main effects of stimulation (F1.40,16 = 7.68, p = 0.018, ηp2 = 0.26), time (F1,16 = 33.64, p < 0.001, ηp2 = 0.71) and a significant stimulation × time interaction (F1.48,32 = 5.44 p < 0.001, ηp2 = 0.62) on power speed scores. Post hoc comparisons revealed that bilateral anodal premotor stimulation significantly improved power speed as compared to bilateral anodal cerebellar stimlation (p = 0.034) and sham tDCS (p = 0.047) after intervention. No significant difference was observed between anodal cerebellar stimulation and sham tDCS (P = 0.477). Between-condition comparisons of power speed showed no significant difference between conditions in the pre-intervention measurement [PM vs sham (t = 0.844, p = 0.411), CB vs sham (t = 0.392, p = 0.700), PM vs CB (t = − 0.905, p = 0.379)]. Also comparisons between pre-to post intervention conditions showed no significant differences in the sham stimulation condition (t =  − 0.51, p = 0.611), but significant differences were obtained in the premotor (t =  − 8.96, p < 0.001) and cerebellar stimulation conditions (t =  − 4.73, p < 0.001).
