Endurance
For the double legs circle test, The results of the ANOVA showed no significant main effect of stimulation (F1,16 = 0.85, p = 0.436, ηp2 = 0.05), but a significant effect of time (F1,16 = 23.71, p < 0.001, ηp2 = 0.59), and no significant stimulation × time interaction (F2,32 = 0.35, p = 0.703, ηp2 = 0.02) on endurance scores). Between-condition comparisons of endurance showed no significant difference between all conditions in the pre-intervention measurement [PM vs sham (t = 0.752, p = 0.463), CB vs sham (t = -0.112, p = 0.912), PM vs CB (t = 0.891, p = 0.386)]. Comparisons between pre to post intervention conditions showed no significant differences in the sham stimulation (t = − 1.94, p = 0.070), but significant performance enhancements in the premotor (t =  − 2.85, p = 0.011) and cerebellar stimulation conditions (t =  − 2.98, p = 0.009).
