An empirical study of an American flag football game course to promote Gross Motor and Physical Fitness in 5-6 year old preschoolers

Objective:To explore the effects of the Flag rugby game courses on the development of Gross Motor and physical fitness in 5-6 year old preschoolers. Methods:Using the Flag rugby game courses as an intervention, a total of 56 preschool children aged 5-6 years (57.14% girls) were selected to participate in Class A and Class B through a random sampling method to see the effects of the flag rugby game courses on their Gross Motor and Physical Fitness. Results:After 12W exercised，In the comparative analysis of subjects' Gross Motor and Physical Fitness test results.We found that the ExG differed significantly(P<0.01) in the test results of Gross Motor and Physical Fitness,and a 2 (group: ExG,ConG)×2 (time: 0w,12w) repeated measures ANOVA was performed and found was interacted significantly (P<0.001) in Total Locomotor Subject Score (F=38.287, p=0.000, ES=0.415),Total Object Control Subject Score(F=164.453, p=0.000, ES=0.753),Total Gross Motor Score (F=192.409, p=0.000, ES=0.781),and found was interacted significant (P<0.05) in Grip strength (F=5.030, p=0.029, ES=0.085),Sitting forward bending (F=6.957, p=0.011, ES=0.114),15m obstacle runing(F=4.185, p=0.046, ES=0.072),Walking the balance beam(F=7.504, p=0.008, ES=0.122).In the comparative analysis of the results of Gross Motor tests and Physical Fitness in subjects of different genders.The main effect of gender was significant (P<0.05) just in Total Object Control Subject Score (F=5.200,P=0.027,ES=0.850).The Group*Gender*Time interaction was significant(P<0.05) just in Horizontal Jump (F=5.177,P=0.027,ES=0.091). Conclusion:It is recommended to promote the Flag rugby game program in the sports curriculum of preschool children aged 5-6 years old, which can improve the overall level of Gross Motor and Physical Fitness development of preschool children aged 5-6 years old.
