To investigate the neuro-muscular coordination of the Kendo Champions, we measured the tensions of blow with a wooden sword, bamboo sword and a split bamboo on the occasion of Menblow and hard blow (Suemonogiri). Simultaneously we recorded the EMG of M. biceps brachii and triceps brachii of both arms, then the time elapsed between the starting of the motion of two limbs, each other four limbs, when subject felt to start them synchronusly. Our results are in the following. 1) The well trained Kendo Champion makes a blow by useing of M. triceps brachii more effectively, and at this moment M. biceps brachii is relaxed, after several repetitions, the same pattern of those EMG are obtained. On the contrary, the untrained subjects are tend to blow by using of M. triceps brachii uneffectively, at this moment biceps brachii is contracted very often and the different patterns of EMG are obtained as they act the same repetitive motions. 2) The difference of the blow energy between the well trained Kendo Champions and untrained subjects is larger than the difference between the tension of them. 3) In measurement of the time elapsed between the starting of the motion of two limbs, we couldn't succeeded to find the significant difference between the well trained and untrained group.
