智慧体育作业对男大学生体质健康的影响

Impact of smart physical education assignment on physical health of male college students

目的探究智慧体育作业对男大学生体质健康的影响,为提高男大学生体质健康水平和实施智慧体育作业提供理论支持与实践参考。方法2023年9月至2014年1月,采用方便抽样方法选取湖南工程学院大二年级6个跆拳道男生限选班的317名学生为研究对象,随机分为干预组(157名)和对照组(160名)。干预组除按照公共课教学大纲实施教学外,每周通过智慧化手段布置体育作业2次,每次25~35 min,干预时长为15周;对照组按照公共课教学大纲正常实施教学。分别在干预前后对两组体质健康各项指标进行测试,通过t检验和Mann-Whitney U检验比较干预前后两组同学体质健康各项指标差异。结果干预后,干预组学生肺活量、50 m跑、坐位体前屈、1000 m跑与引体向上成绩均较干预前提高,分别由(3918.27±737.34)mL,7.88(7.53,8.45)s,9.80(2.70,15.75)cm,4.30(4.12,4.50)min和3.00(0.00,7.50)次提高至(4574.19±800.61)mL,7.65(7.37,8.12)s,17.20(11.80,21.55)cm,4.13(3.58,4.31)min和5.00(1.00,10.00)次(t/Z值分别为-7.60,2.61,-8.39,5.62,-2.72,P值均<0.05)。干预前,干预组与对照组体质健康各项指标差异均无统计学意义(P值均>0.05)。干预后,干预组学生肺活量、50 m跑、坐位体前屈、1000 m跑与引体向上成绩均优于对照组[(4310.97±808.90)mL,7.75(7.40,8.30)s,14.10(8.42,17.87)cm,4.29(4.08,4.45)min和4.00(1.00,7.00)次](t/Z值分别为2.91,-4.55,-4.75,-4.51,2.58,P值均<0.05)。结论每周2次25~35 min智慧体育作业能够有效提高男大学生体质健康水平。建议在保证公共体育课程运动量与运动强度的同时,布置适量智慧体育作业以提高大学生体质健康水平。

Objective To explore the impact of smart physical education assignment on physical health of male university students,so as to provide theoretical support and practical references for physical health improvement of male university students and implementing smart sports assignments.Methods From September 2023 to January 2024,317 sophomore male students from six Taekwondo elective classes at Hunan Institute of Engineering were selected and were randomly divided into an intervention group(n=157)and a control group(n=160).The intervention group was given sports assignments twice a week through smart means with an intervention duration of 15 weeks,each time for 25-35 minutes,in addition to the teaching according to the public course syllabus,while the control group was taught according to the public course syllabus.The physical and health indicators of both groups were tested before and after intervention,then the differences in various physical health indicators between two groups of students before and after intervention were compared through t-test and Mann-Whitney U test.Results After the intervention,the vital capacity,50 m run,sit-and-reach,1000 m run,and pull-up scores of the intervention group significantly improved compared to those before intervention.The scores improved from(3918.27±737.34)mL,7.88(7.53,8.45)s,9.80(2.70,15.75)cm,4.30(4.12,4.50)min and 3.00(0.00,7.50)times to(4574.19±800.61)mL,7.65(7.37,8.12)s,17.20(11.80,21.55)cm,4.13(3.58,4.31)min and 5.00(1.00,10.00)times,respectively(t/Z=-7.60,2.61,-8.39,5.62,-2.72,P<0.05).Before intervention,there was no statistically significant difference in physical health indicators between the intervention group and the control group(P>0.05).After intervention,the scores of the intervention group on the vital capacity,50 m run,sit-and-reach,1000 m run and pull-up,were significantly higher than those of the control group[(4310.97±808.90)mL,7.75(7.40,8.30)s,14.10(8.42,17.87)cm,4.29(4.08,4.45)min and 4.00(1.00,7.00)times](t/Z=2.91,-4.55,-4.75,-4.15,2.58,P<0.05).Conclusions Having 25-35 min smart physical education assignment twice a week can effectively improve physical health level of male college students.It is recommended to assign appropriate amount of smart sports homework to improve physical health level of college students,while ensuring the amount and intensity of physical activity in public physical education courses.
