Is change of direction influenced by motor competencies? A possible response from a MOBAK-based study in Italian schoolchildren

Background: Change of direction (COD) ability requires higher motor control capacity and helps children improve individual motor skills. Likewise, basic motor competencies (BMC) are relevant during child maturation and may interleave with COD ability. This study aimed to investigate the possible individual determinants between the COD ability and the BMC, cognitive skills, and anthropometrics characteristics in Italian primary school children aged 6 to 11. Methods: Children of both sexes (N.=221) were recruited from primary schools (grade 1 to 5) of Northwestern Italy. COD was assessed by 10×5 m Shuttle Run Test; motor coordination by the Motor Coordination (Motorische Basiskompetenzen, MOBAK) 1-6 test battery, whereas Trail Making Test was used to assess cognitive performance. Results: A stepwise linear regression indicated that motor competencies level - assessed by the MOBAK Test - is the most fitting dimension describing COD performance for girls, with the highest R2 in Grade 5 (SEE=0.56); and the lowest SEE in Grade 5 (SEE=1.44); moreover, for boys the highest in Grade 3 (SEE=0.52) and the lowest SEE in Grade 4 (SEE=1.30). Conclusions: This study confirms the biunivocal relationship between COD and BMC, and the need for physical education teachers and trainers to stimulate both, during growth.
