Abstract

The purpose of this study was to investigate the characteristic of the back takeoff leg in a karate grappler using ground reaction force, motion analysis from video camera, Jump test. Fourteen collegiate male students were analyzed. The participants were assigned to two groups (grade holder group, n=6; non-holder group, n=8). In the grade holder group, a degree of the ground reaction force before becoming the maximum was steep( p<0.05) and ground reaction force at start 0.1 seconds later greater than non-holder group (p<0.01). The grade holder group was unweighting because of squatting in grand reaction force. But there was no unweighting in nonholder group. Karate grappler has unique characteristics of hip extension, knee flexion and ankle dorsiflexion. In the national team group, there was significant greater depth jump and horizontal depth jump of one leg than collegiate group. Our results indicated that, when karate grappler moved forward by a jab, it’s early and at the top speed by smooth weight movement to a hind leg because of appropriate lower leg. These result suggest the time of a jab become shorten until a movement end. Furthermore, it was thought that the reinforcement of the jump power in the right and left one leg was important to forward the movement.
