Abstract

The purpose of this study was to investigate the characteristic of the back and front takeoff leg in a karate grappler using ground reaction force, motion analysis from video camera. Ten collegiate male students were analyzed. The participants were assigned to two groups (grade holder group, n=6; non-holder group, n=4).
 In all subjects, the front leg affect for posture maintenance before the stab movement start Subsequently, Weight movement happened from a foreleg to a hind leg right before forward movement happened.Time to need from Peak ground reaction force of hind leg to stab movement end were mean 0.16 seconds in the grade holder group, but 0.37 seconds in the non-holder group. Karate grappler has strong in power to jump into forward relationship of hip extension, knee flexion, ankle dorsiflexion and muscle strength.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 that time of a jab was 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 movement.
