In summary, results of the present study indicate that physiological demands of competitive TKD fight in women, measured by HR and LA responses, are considerably higher than the physiological demands of TKD or karate training exercises. LA values determined after the fight suggest that the anaerobic metabolism plays a major role in this particular sport. Based on our results and the results of previous research we believe that the emphasis in conditioning for TKD should be placed on high-intensity anaerobic exercises and intermittent activities.
