摘　　要：目的探讨儿童足弓三维发育状态与儿童短距离奔跑(以下简称短跑)能力的相关性。方法本研究为回顾性研究。选择重庆市某学校7~15岁中小学生共640人作为研究对象,其中男324人,女316人,均使用三维扫描仪"Foot Secret"扫描足部三维轮廓以获得足弓指数及足弓体积,并测试受试者50米短跑成绩。根据性别及年龄将受试者分为6组:7~9岁男子组(93人),7~9岁女子组(103人);10~12岁男子组(116人),10~12岁女子组(112人);13~15岁男子组(115人),13~15岁女子组(101人)。对各组足弓指数、足弓体积与50米短跑成绩进行相关性分析。结果在7~9岁组中,男子组左右足与女子组左右足的负重足弓指数、非负重足弓指数以及50米短跑成绩比较,差异均无统计学意义(P>0.05);除7~9岁女子组左足负重足弓体积、左足非负重足弓体积与50米短跑成绩的相关系数无统计学意义(P>0.05)外,7~9岁男子组的左足负重足弓体积、左足非负重足弓体积、右足负重足弓体积、右足非负重足弓体积,以及7~9岁女子组右足负重足弓体积、右足非负重足弓体积与50米短跑成绩均呈弱相关性(r=-0.301、-0.294、-0.295、-0.207、-0.279、-0.278),且相关系数均有统计学意义(P<0.05)。在10~12岁组中,除10~12岁女子组右足负重足弓指数、右足非负重足弓指数与50米短跑成绩呈弱相关性(r=0.250、0.243),且相关系数具有统计学意义(P<0.05)外,10~12岁男子组左足负重足弓指数、左足非负重足弓指数、右足负重足弓指数、右足非负重足弓指数,以及10~12岁女子组左足负重足弓指数、左足非负重足弓指数与50米短跑成绩的相关系数均无统计学意义(P>0.05);除10~12岁女子组左足负重足弓体积、左足非负重足弓体积与50米短跑成绩的相关系数无统计学意义(P>0.05)外,10~12岁男子组左足负重足弓体积、左足非负重足弓体积、右足负重足弓体积、右足非负重足弓体积,以及10Objective To explore the association between arch morphology and sprint performance in children,utilizing arch volume and arch index to assess arch development,and comparing and analyzing its relationship with athletic capability.Methods A total of 640 primary and secondary school students(324 boys and 316 girls)aged between 7 to 15 years were recruited from Chongqing Municipality.Foot arch index and arch volume were measured by"Foot Secret 3D Foot Plantar Scanner".Performance of 50-meter sprint was assessed.The participants were stratified into 6 groups based upon gender and age:boys aged 7-9 years(n=93),girls aged 7-9 years(n=103),boys aged 10-12 years(n=116),girls aged 10-12 years(n=112),boys aged 13-15 years(n=115)and girls aged 13-15 years(n=101).The correlations between arch index,arch volume and athletic performance were examined.Results In the age group of 7-9 years,the comparisons of both the left and right foot's weight-bearing arch index and the non-weight-bearing arch index between boys and girls showed no statistical significance(P>0.05).However,except for the comparisons of the left foot's weight-bearing arch volume and non-weight-bearing arch volume in the 7-9 year-old girls group,which showed no statistical significance(P>0.05),the following comparisons indicated a weak correlation with the 50-meter sprint performance and were statistically significant(P>0.05):the left foot's weight-bearing arch volume,the left foot's non-weight-bearing arch volume,the right foot's weight-bearing arch volume,and the right foot's non-weight-bearing arch volume in the 7-9 year-old boys group(r=-0.301,r=-0.294,r=-0.295,r=-0.207),and the right foot's weight-bearing arch volume and non-weight-bearing arch volume in the 7-9 year-old girls group(r=-0.279,r=-0.278).In the 10-12 years age group,the comparisons of the right foot's arch index-both weight-bearing and non-weight-bearing-with the 50-meter sprint performance in the 10-12 year-old girls group showed a weak correlation(r=0.250,r=0.243)and were statistically signif
