摘要
目的探讨小排球运动干预对儿童精细动作能力和体质健康的影响,为儿童运动干预提供依据。方法:随机选取天津市76名9—12岁儿童为研究对象,分为实验组(38人)和对照组(38人)。实验组进行为期12周的每周3次小排球运动干预,对照组维持日常活动。通过九洞测试、凹槽划走测试、双臂调节测试评估精细动作能力,并通过BMI、体脂百分比(BF%)、立定跳远、握力等指标评估体质健康。基线数据使用独立样本T检验,干预前后差异采用配对样本T检验和重复测量方差分析。结果:干预前,两组在精细动作能力和体质健康指标上无显著差异(P值均>0.05)。干预后,实验组在凹槽划走测试(12.27±7.59至11.53±7.39,P<0.01)和双臂调节测试(225.17±89.68至203.28±78.87,P<0.01)中的成绩显著提升。BMI显著降低(17.53±2.83至16.38±2.83,P<0.01),立定跳远显著提高(158.45±30.36 cm至169.61±25.97 cm,P<0.01),握力显著增强(17.22±4.96 kg至18.22±4.62 kg,P<0.01)。重复测量方差分析显示时间主效应和时间×组别交互效应在BMI(F=9.405,P=0.003,偏η^(2)=0.113)、立定跳远(F=4.319,P=0.041,偏η^(2)=0.055)及握力(F=135.818,P<0.001,偏η^(2)=0.647)上显著。对照组在这些指标上无显著变化(P值均>0.05)。结论:小排球运动干预显著改善了儿童的精细动作能力和体质健康,特别是在减脂和增强下肢力量、握力方面效果突出。本研究为小排球运动在儿童健康促进中的应用提供了科学依据,建议未来研究进一步探索其长期效果。
Objective To explore the effects of small volleyball intervention on children's fine motor skills and physical health,and provide a basis for children's sports intervention.Method 97 children aged 9-12 years old in Tianjin were randomly selected as the research subjects and divided into an experimental group(38 people)and a control group(38 people).The experimental group underwent a 12 week intervention of small volleyball three times a week,while the control group maintained daily activities.Evaluate fine motor skills through the nine hole test,groove walking test,and double arm adjustment test,and assess physical health through indicators such as BMI,body fat percentage(BF%),standing long jump,and grip strength.The baseline data was analyzed using independent sample t-test,and the differences before and after intervention were analyzed using paired sample t-test and repeated measures ANOVA.Results Before the intervention,there was no significant difference in fine motor skills and physical health indicators between the two groups(P values>0.05).After intervention,the experimental group showed significant improvement in the groove scratch test(12.27±7.59 to 11.53±7.39,P<0.01)and double arm adjustment test(225.17±89.68 to 203.28±78.87,P<0.01).BMI significantly decreased(17.53±2.83 to 16.38±2.83,P<0.01),standing long jump significantly increased(158.45±30.36 cm to 169.61±25.97 cm,P<0.01),and grip strength significantly increased(17.22±4.96 kg to 18.22±4.62 kg,P<0.01).Repeated measures ANOVA showed that the time main effect and time x group interaction effect were significant in BMI(F=9.405,P=0.003,biasedη?=0.113),standing long jump(F=4.319,P=0.041,biasedη?=0.055),and grip strength(F=135.818,P<0.001,biasedη?=0.647).The control group showed no significant changes in these indicators(P values>0.05).Conclusion The intervention of small volleyball significantly improves children's fine motor skills and physical health,especially in reducing fat and enhancing lower limb strength and grip strength.This study provides a scientific basis for the application of small volleyball in promoting children's health,and suggests further exploration of its long-term effects in future research.
