The aim of this study was to ascertain foot pressure during basic karate motions. Subjects were divided into two groups, one of which performed kata (forms) (n＝10) and the other of which performed kumite (sparring) (n＝9)． The basic motions of gyakutsuk i (a punch with the opposing leg forward), maekeri (a front kick), and tsukiuke (a punching block) were performed by all subjects. These motions were recorded with two high-speed cameras (HSV＝1700), and foot pressure was measured using a Zebris FDM sensor. Measurement parameters for all 3 motions were duration of motion (DM), foot pressure (FP), distance traveled by the center of pressure (DCOP) and velocity of the COP (VCOP)．When gyakutsuki and maekeri were performed, the DM, DCOP, and VCOP did not differ significantly. When the tsukiuke was performed, however, DCOP and VCOP differed significantly between kata and kumite. DCOP and VCOP were greater when tsukiuke was performed as part of a kata than when it was performed during kumite. Results revealed that while performing kata karate practitioners performed greater motion that involved rotation of the hip joint.
