dc.description.abstractAlthough taekwondo (TKD) is the most popular martial art in the world, it has not been researched extensively. Some studies report the physiological profile of TKD athletes, but the functional demands of a TKD combat are unknown. PURPOSE: To determinate the physiological demands of a TKD combat. METHODS: Five women from the Colombian TKD team (21 ±2,92 years; 55,8 ±5,45 kg; 1,64 ±2,68 m) in their precompetitive season gave their informed consent for the study. They performed a simulated combat: three 2-minutes rounds with 1-minute rest intervals. In the first and second rounds, they did intermittently movements of defense/attack (10/15s round 1 and 10/10s round 2); and in the third round, they did their higher effort to attack during the whole round. Oxygen consumption (VO2) and respiratory quotient (R) were measured during combat using a portable gas analyzer system (Metamax II). Blood lactate levels (LAC) were measured in capillary blood using Accutrend. Maximal VO2 (VO2 max) were measured following endurance Bangsbo test protocol and using gas analysis. Comparisons between rounds and rest periods were made with one way ANOVA for repeated measures and Holm-Sidak method for pairwise comparisons. RESULTS: VO2 max were 46,99 ±2,68 ml.kg-1.min-1. Combat VO2 expressed as VO2 max percentage were above than 85% during the 3 rounds (85,1 ± 8,5; 85,9 ± 8,5 and 85,3 ± 4,8%, respectively, p=0.916), and were above the anaerobic threshold of each athlete (p<0,05). In contrast, during rest periods VO2 significantly decreased (57,1 ± 8,3 and 55,8 ± 12%, for the first and second rests respectively) (p=<0.01). R values during rounds and rests were between 1,09 and 1,12. LAC were 2,3±0,4 mmol/l in rest and significantly increased (p<0,013) during combat to reach 6,3±2,4; 8,8±2,8 and 9,8±3,1 mmol/l for the 3 rounds respectively. CONCLUSIONS: VO2 max of female TKD athletes were similar to the reported in other studies (43.6 ± 6.1 ml.kg-1.min-1)(1). TKD combat may be considered as a lactic anaerobic (high intensity) intermittent work because the VO2 were higher than 85% and above anaerobic threshold; R were always above 1,09; and LAC were higher than 6,3 mmol/l. TKD athletes should have high aerobic capacities that permit a better recovery during rest periods.
