Heart rate and lactate responses to taekwondo fight in elite women performers

The purpose of this study was to examine heart rate (HR) and blood lactate (LA) concentration before, during and after a competitive tae kwon do (TKD) fight performed by elite women performers. Specifically, we were interested to see whether HR and LA responses to competitive fight were greater than to TKD or karate exercises published in scientific literature. Seven international-standard women TKD fighters participated in the study. HR was recorded continuously throughout the fight. LA samples were taken before and 3 min after the fight and analyzed using an Accusport portable lactate analyzer. At the beginning of the fight, HR significantly increased (p<0.01) from pre-fight values of 91.6 beats/min to 144.1 beats/min. During the whole fight mean HR was 186.6 beats/min and remained significantly elevated (p<0.01) at 3 min into recovery. HR values expressed as a percentage of maximum HR averaged during the whole fight at 91.7%, respectively. LA concentrations significantly increased (p<0.01) 3 min after the fight and averaged 82% of peak LA values recorded after the VO2max test. These results 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. The observed HR and LA responses suggest that conditioning for TKD should generally emphasize high-intensity anaerobic exercises.
