	Age (years)	Gender (female/male)	LQ	Sports/week (hours)	Fine-motor/week (hours)
MG n = 17	26.53 ± 0.95	8/9	87.82 ± 3.92	2.71 ± 0.47	0.18 ± 0.18
CG n = 18	27.28 ± 0.75	8/10	88.00 ± 4.08	3.44 ± 0.75	0.33 ± 0.28

Hours of sports per week and hours of fine-motor training per week were assessed with a questionnaire, handedness (Laterality Quotient, LQ) was assessed with the Edinburgh Handedness Scale (range: −100 (full left-handed) to +100 (full right-handed)). Statistical analysis revealed no significant differences in age, gender, LQ, sports/week or fine-motor training/week between groups. All values are depicted as mean ± standard error of the mean.
