Study on the Formation of Foot Sole Contact Surface and the Longitudinal Arch of Foot Skeleton and Nursery Environment in Childhood
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.5 Vol.5】
Two hundred and fifty six kindergarten were taken photographs by pedoscope to observe the formation process of the arch of the foot.
Thirty two who had what we call "flat-footed" were X-ray photographs respectively. We investigated the relationship between foot sole contact surface and the structure of foot skeleton of them after five months training further.
1) Observing the formation process of the arch of the foot on the foot sole contact surface from the view point of H-Line, Children aged 5, 74% (Men 70%, Women 78%) were shaped, children aged 4, 15.5% (Men 18%, Women 13%) and children aged 5, 18% (Men 21%, Women 15%) had what is called "flat-footed".
2) After five months training the change of foot sole contact surface as well as contact area, arch of the foot area, arch of the foot area, arch of the foot ratio took the average and increase could be found in them, but any significant relationship could not.
And when examined the formation of the structure of foot skeleton from the view point of the inclination angle A of calcaneus and the inclination angle B of talus, any significant relationship in the training could not be found.
As 1 mentioned above, in this training, the reason why there was little change of foot sole skeleton formation was the fact that training period was too short, and that we could not give them sufficient private guidance.
Considering those effects, we are still keeping on having training on them.
