Research on Promoting Students'Physical Fitness through Physical Fitness Training based on LTAD Model
The objective of this study is to observe the effect of 12 weeks of physical fitness training on the physical fitness of primary school students.Methods:Two students in the fourth grade of a primary school in Harbin were divided into physical fitness training group(intervention group)and regular physical education group(control group),with 40 students in each group.The intervention was held twice a week for 40 minutes for 12 weeks.Both groups were tested for physical fitness before and after the intervention.Results:Before the experiment,there was a significant difference in waist circumference(p＜0.05)between the two groups,a high significance difference(p＜0.01)between the two groups and a 20-second round trip,and no significant difference(p＞0.05)between the two groups.In the experimental group,height,weight,waist circumference,20-meter round trip,left-handed grip strength,30s sit-ups,standing long jump,sitting forward bending,50-meter running,20s repeated span had highly significant differences(p＜0.01),and BMI and right-handed grip strength had significant differences(p＜0.05).There were significant differences in height,weight,20m round trip,30s sit-ups,sitting forward flexion,and 20s repeated span in the control group(p＜0.01).There were highly significant differences in waist circumference,20-meter round trip,left and right hand grip strength,50-meter running,and 20s repeated span changes(p＜0.01),and BMI differences(p＜0.05).Conclusion:Physical fitness training based on LTAD model has a significant effect on promoting physical health of primary school students.
