Pressure Distribution Patterns and Shapes of Foot under Long-Term Loads

In this paper, we use instruments to scan the feet of athletes with no foot disease or previous injury from Beijing Sport University and ordinary college students from Tsinghua University and obtain the foot shapes and the changes therein of the subjects. Then we design and extract indices like foot length and foot width, perform statistic analysis of the foot shapes of young athletes under different loads, and obtain a group of data regarding the foot shape features of young athletes under different loads. This group of data can provide experimental operation experience and data support for the establishment of national young athlete foot shape index database. By analyzing the differences between the foot shape indices of young athletes under different loads, we find that different loads have some impacts on the foot shape changes. There are great differences between the foot shape indices of young athletes and ordinary college students in China, and of the young athletes in China, foot shape indices like foot length and width are likely to vary greatly due to different loads.
