摘要：The shape of the posterior profile of the lower legs in the lateral view was examined by Moire photography in 281 healthy, Japanese aged 18-22 years participated in different sports.Subjects were 140 male and 28 female non-athletes, 30 male and 14 female swimmers, 21 male sprinters, and 48 male kendo players.Using a cubic spline function and geometrical data from the Moire photographs, the posterior profile of the lower leg in the lateral view was reconstructed from the level of the apex captitis fibulae to the pternion. After standardization of the size factor, the posterior profile of the lower leg in the lateral view was represented by 49 measurements.These measurements were defined as the distances from 49 points, which divided at regular intervals between both ends of the reconstructed line, to the posterior profile of the lower leg in the lateral view.These measurements were analyzed by the factor, clustering and MDS analyses. The shape of posterior profile of the lower leg varied by sport group: sprinters and kendo players had a posterior profile that protruded more than the others did.Lateral differences in the shape were recognized in every group.Especially, the lateral difference was marked in male non-athlete and male swimmer groups.These results suggest that the posterior profiles of the lower legs are greatly influenced by not only sport type, but also daily activities.
