The Relationships between Static Balance and Physical Activity in Preschool Children at 6-7 Years of Age

摘要

This study was aim to measure static balance and investigate its association with physical activity levels in children at 6-7 years of age. The modified Chinese version of the Preschool-age Children’s Physical Activity Questionnaire (Pre-PAQ) was deployed to evaluate the levels of participants’ routine physical activity. The center of pressure information indicating body sway was measured by static balance tests using a plantar pressure measurement platform. Seventy-two children completed tests. Girls had significantly lower body sway compared to boys in all conditions. In the bipedal conditions, there was no significant difference between eyes-closed and eyes-open states. Visual information did not influence children static balance performance. In the unipedal conditions, single-leg balance of dominant side did not statistical differ from that of another side. Children did not show dominant habit. Physical activity levels were moderately correlated with bipedal static balance for both genders. Hence, the physical activity of children negatively affects static balance. Considering previous results, we suggest that specific balance interventions at moderate level of physical activity are reasonable for improving preschool children’s balance.
