摘要：The objectives of the present study were: to examine the relationship between kendo competition levels and men strike times in 20 university kendo club members; and to determine factors for shortening men strike times. LED lamps were attached to the men and the kote (the strike targets), and subjects struck in the direction of the lit LED lamp with maximal effort from a distance of 2.30 m. Phase times, movements, and ground reaction force on both feet were analyzed. The results were as follows. 1. Subjects of higher competition levels tended to demonstrate shorter men strike times. Reaction times, movement times, and shinai upswing phase time also tended to be shorter. 2. Factor for shortening men strike times in the upswing phase consisted of the following: lifting the right foot from the ground quickly, simultaneously pushing off the ground with great force with the left foot, quickly lifting the right thigh forward while moving the body forward, and to increase the range of upswing motion of the shinai with high velocity. In the downswing phase, the shinai should be swung at a higher velocity, and the left shoulder should be flexed more when striking.
