小篮球对幼儿灵敏素质的影响的meta分析

Meta-analysis of the Influence of Small Basketball on PreschoolChildren's Agility

背景:灵敏素质是与运动和运动机能增强相关的标志之一,良好的灵敏素质可以有效预防生活中可能受到的伤害,小篮球对幼儿灵敏素质的影响尚无统一意见。目的:通过meta分析,探索小篮球对幼儿灵敏素质的影响,为幼儿体质研究提供研究证据。方法:以“幼儿”and“篮球”为检索主题词对中国知网、万方、维普数据库进行检索,检索时限为建库至2021年9月,根据纳入和排除标准排除不符合要求的文献,对所纳入的文献进行文献质量评价。若研究间异质性较高,首先逐一排除文献进行敏感性分析,若异质性仍然高则对可能的异质性因素进行亚组分析。meta分析软件采用Review Manager5.4。结果:meta分析结果显示与常规体育活动相比篮球运动对幼儿10m折返跑成绩提高了0.35s,(MD=-0.35,95 CI%:[-0.81~0.11]),结果没有统计学差异(P=0.14)。亚组分析发现4-5岁亚组与常规体育活动相比篮球运动提高了幼儿10m折返跑成绩0.17s,结果没有统计学差异(P=0.7);5-6岁亚组与常规体育活动相比小篮球训练提高了幼儿10m折返跑成绩0.66s,结果有统计学差异(P<0.01)。结论:篮球训练与常规体育活动相比可以有效提高幼儿的灵敏素质,但是不能否认常规体育活动对幼儿体质的发展的作用。

Background:Agility is one of the signs related to sports and enhancement of motor function.There is no unified opinion on the influence of small basketball on preschool children's agility.Objective:To explore the influence of small basketball on preschool children's agility through meta analysis,and to provide research evidence for preschool children's physique research.Methods:“preschool children”and“basketball”were used as the keywords to search CNKI,Wanfang and VIP databases,and the retrieval time was from the database establishment time to September 2021.Unqualified literatures were excluded according to the inclusion and exclusion criteria,and the literature quality of the included literatures was evaluated.If the heterogeneity between studies was high,sensitivity analysis was conducted by excluding literatures one by one;if the heterogeneity was still high,subgroup analysis was conducted for possible heterogeneity factors.The meta-analysis software adopted was Manager5.4.Results:Meta-analysis results showed that basketball improved preschool children's performance in 10m retrace running by 0.35s compared with conventional sports(MD=-0.35,95CI%:[-0.81~0.11]),with no statistical difference(P=0.14).The results of subgroup analysis showed that basketball improved preschool children's performance of 10m returnable run by 0.17s in the 4-5 years old subgroup compared with regular sports activities,and there was no statistical difference(P=0.7).Compared with regular sports activities,little basketball training improved preschool children's 10m returnable running performance by 0.66s,with statistical difference(P<0.01).Conclusion:Basketball training can effectively improve preschool children's agility compared with regular sports,but we can't deny the role of regular sports in the development of preschool children's physique.
