Study aim: To assess the influence of juggling training on mental rotation performance in children.Material and methods: Two groups of girls aged 6 - 14 years were studied: experimental (EG; n = 26) and control (CG; n = 24). All girls solved a mental rotation task with 3-D block figures on computer screen (pre-test). After the initial test, EG girls participated in juggling training for 3 months; the CG girls participated in light strength training with theraband stretch bands. After 3 months, all girls solved the mental rotation task again (post-test). The post-pre differences in the mental rotation performance were recorded.Results: Children who learned juggling performed the mental rotation task significantly (p<0.05 - 0.01) faster, in terms of reaction time, at non-zero angular disparity than their mates who were strength-trained.Conclusions: Since mental rotation skills enhance spatial imagination, problem solving and mathematical skills, it may be assumed that juggling training enhances also other cognitive domains and is worth implementing in the education process.
