Are Individual Differences in Sport Vision in Childhood Innate or Resulting from Experience in Sport?
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.22 Vol.22】
Two experiments were carried out to clarify the cause of individual differences in visual functions of elementary school children. 1st Experiment:
DVA (dynamic visual acuity) and Momentary vision were measured in 110 male and female children aged 8 and 9. The measurements were then analyzed in term of their relationship with the subjects' physique, locomotive ability, liking or disliking for sports, and daily sport habits.
A significant difference was revealed in DVA was shown between the group with higher performance and one with lower performance in both male and female subjects. Similarly, significant difference was found in Momentary vision in either sex.
The males, the group with higher DVA was found to possess better physique and locomotive ability and tend to like sports. In the case of the females, DVA was not related to physique and was apparently not related to sports, either. 2nd Experiment:
DVA, Eye movement and Functional visual field were examined in the group of children and their parents. The result of analysis showed that there was no significant correlation in any of these visual functions between the children and their parents.
The results of 2 experiments suggest the followings:
1) While there are great individual differences in DVA and Momentary vision among both male and female 3rd graders.
2) In the male and female subjects, the DVA and Momentary vision is related locomotive ability and liking or disliking for sports.
3) There is no correlation between children and their parents in DVA, Eye movement and Functional visual field.
Therefore, it may be concluded that the superiority/inferiority in these visual functions is not innate.
