The effect of mini-basketball on upper limb strength performance in children aged 4-6 years:a Meta-analysis
Objective To systematically evaluate the effect of mini-basketball on children's upper limb strength in China,and to provide basis for the development of kindergarten mini-basketball and the improvement of children's upper limb strength perform-ance.Methods CNKI,Wanfang Data,VIP,PubMed,and Web of Science databases were searched from the establishment of the database to July 26,2023.The PICOST model was used for literature screening,and 13 literature with a total of 20 studies were fi-nally included.The Cochrane System Evaluation Criteria was used for literature quality evaluation.Review Manager 5.4 and Stata 17 were used for statistical analysis and publication bias test.Results A total of 939 children were included in 20 studies,including 470 in the experimental group and 469 in the control group.Meta-analysis showed that mini-basketball had an extremely significant effect on the improvement of children's upper limb strength(SMD=0.83,95％CI=0.53-1.13,Z=5.40,P＜0.01).The results of subgroup analysis showed that there was no significant gender difference in the improvement of children's upper limb strength by mini-basketball(P＞0.05),mini-basketball exercise with an intervention time of less than or equal to 30 minutes(SMD=0.49,95％CI=0.29-0.70,Z=4.70,P＜0.01)and an exercise cycle of more than 12 weeks(SMD=1.25,95％CI=0.54-1.96,Z=3.45,P＜0.01)can achieve a better intervention effect on the upper limb strength of children.Meta-regression results showed that the exercise intervention time was the main source of heterogeneity(t=2.71,95％CI=1.38-22.93,P＜0.05).Egger's test showed that the publication bias of the included studies was not statistically significant(t=0.78,P＞0.05).Conclusions Mini-basketball training can improve the upper limb strength of children,but there is no significant gender difference.The upper limb strength is af-fected by the restriction of intervention time and exercise cycle.Schools can appropriately add small basketball in physical education classes to improve children's upper limb strength.
