	1	Effect of the Resistance Exercise on Elementary School Students’Physical Fitness显示文摘Background Physical activity programs using components of resistance have the potential to improve health in school chil-dren.The purpose of this study was to examine the effect of a school-based resistance exercise program on physical fitness in elementary school students.Methods The sample was 256 children(mean age=8.3±2.5 years;119 girls)from kindergarten to 5th grade.Participants performed a 10-min resistance exercise 2-3 times in each school day.Physical fitness outcomes were assessed using President’s Physical Fitness Challenge test.Measures were collected at baseline and at a 6-month post-test time point.A 2×2 doubly MANOVA was employed to examine the effect of sex and time.Results The multivariate model was statistically significant with a main time effect(Wilks’λ=0.19,F=290.9,P<0.001).Follow-univariate tests found significant differences between time-points on flex arm hang(P=0.033),shuttle run(P<0.001),and 1-mile run/walk times(P<0.001).Conclusions A 6-month resistance exercise program improved upper body strength and cardiorespiratory endurance in elementary school aged children.The use of resistance exercise intervention during school day can be effectively used to promote physical fitness and ultimately improve the health of children.
