Objective To understand the effect of weight on the physical fitness of preschool children,to reduce the occurrence of underweight and overweight,and to promote the physical health of preschool children. Methods A total of 576 preschool children aged 5~6 in 6 kindergartens from Shanghai were selected as the research objects,and were divided into 3 groups,including group with underweight,normal weight and overweight.Physical fitness test included height,weight,sit and reach,10 m dashes,standing broad jump,softball throwing,side to side jump and balance beam.The correlation between physical fitness and body weight was analyzed. Results With the increase of age,the proportion of underweight decreased,and the proportion of underweight in girls was higher than those overweight group.There was significant difference on the total score of physical fitness among 3 groups (normal weight > underweight > overweight).The body mass index (BMI) in underweight group was positively correlated with physical fitness score (boys r=0.364,girls r=0.344,P<0.05).The BMI in overweight group was negatively correlated with physical fitness score (boys r=-0.515,girls r=-0.498,P<0.01). Conclusions The physical conditions vary in preschool children with different body weights,suggesting that body weight is an indicator of physical fitness.Therefore,underweight and overweight in preschool children is an urgent issue to address.
