- Abstract:
- Objective 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 significant (P<0.05).However,the comparisons of the left foot’s weight-bearing arch index,the left foot’s non-weight-bearing arch index,the right foot’s weight-bearing arch index,and the right foot’s non-weight-bearing arch index in both the 10-12 year-old boys and girls groups showed no statistical significance (P>0.05).Moreover,except for the left foot’s weight-bearing arch volume and non-weight-bearing arch volume in the 10-12 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: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 10-12 year-old boys group (r=-0.273,r=-0.224,r=-0.236,r=-0.273),and the right foot’s weight-bearing arch volume and non-weight-bearing arch volume in the 10-12 year-old girls group (r=-0.224,r=-0.211).In the 13-15 years age group,the comparisons of the left and right foot’s arch index-both weight-bearing and non-weight-bearing-in the 13-15 year-old boys and girls groups with the 50-meter sprint performance showed no statistical significance (P>0.05).However,except for the non-weight-bearing arch volumes of the left and right feet in the 13-15 year-old girls group,which showed a weak correlation with the 50-meter sprint performance (r=-0.233,r=-0.225) and were statistically significant (P<0.05),the comparisons of 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
