GRADING ABILITY OF KENDO ATHLETES

Kendo champions were measured in order to study neuromuscular coordination on blow and to examine influence of Kendo athletics on fundamental human grading ability about grading grip and standing broad jump graded. The results were as followes. 1) As subjects were ordered to voluntarily show one-third, one-second and two-thirds of his own maximum grip strength after checking his maximum value, no discrepancy of voluntary grip strength and ordered strength was shown between well trained Kendo champions and beginners. Standard deviation values of ten times grip strength were not much different between them. 2) As subjects were ordered to voluntarily show one-third and two-thirds of his own maximum standing broad jump after checking his maximum, no discrepancy of voluntary value and ordered value was shown between well trained Kendo champions group and weight training group. Standard deviation values of thirty times jump record were not much different between two groups. 3) Well trained Kendo champions and beginners were measured in blowing down with bamboo-sword at three different distances. In spite of beginners showed varied moments of blow and foot touching the floor when distance was changed, well trained Kendo champions showed uniform moment of them.
