The aim of this study was to measure time-motion variables during simulated karate kumite matches. Twelve (n=12) elite male karateka's who regularly participate in national and international events were recruited from the Free State Karate High Performance Squad in Bloemfontein, South Africa. All simulated fights were recorded and analysed by means of Dartfish, a video analysis software program. Fifty-two percent (52%) of all techniques scored were attributed to upper limb techniques and 48% to the lower limbs. The same values were recorded with regard to the scoring of offensive versus defensive techniques. There were no significant differences (p>0.05) between rounds with respect to the mean counts of techniques used. Furthermore, 61% of the total fighting time was attributed to the various fighting activities and 39% to stoppages. An effort-to-rest ratio of 1.5:1 was also observed regarding the mean effort periods and stoppage intervals. Karateka's predominantly use upper limb karate techniques. With respect to the activity contributions during the kumite matches, it was evident that a high proportion of time (82.5%) was spent on low-intensity or bouncing actions and only 17.5% on contact with the opponent. It is important that basic notational analysis of World Karate Federation karate continues in order to thoroughly document the physical demands of the sport at all levels and categories, including men, women and youth.
