Results of the investigated main and interaction effects in three-way mixed model ANOVAs with three factors: “group” (CE, PE, CE + PE, PE + CE), “prepost” (pretest and posttest) and “time” [baseline (S1 or S4), acutely after first exercise (S2 or S5), acutely after second exercise or rest (S3 or S6)]. BDNF, brain-derived neurotrophic factor; dffactor, degrees of freedom for the investigated factor; dferror, degrees of freedom for the error term of the investigated factor. The level of significance was set at p < 0.05. Significant effects are in bold italics.
