Changes in blood lactate concentrations during taekwondo combat simulation

Area of Science:

• Sports Medicine
• Exercise Physiology
• Biochemistry

Background:

• Taekwondo is a demanding combat sport requiring high levels of physical exertion.
• Understanding the metabolic responses, particularly blood lactate accumulation and clearance, is crucial for optimizing training and performance in taekwondo athletes.

Purpose of the Study:

• To analyze the blood lactate response in young male taekwondo athletes before, during, and after a simulated official taekwondo fight.
• To assess the impact of taekwondo combat on anaerobic lactic metabolism and lactate removal efficiency.

Main Methods:

• Seven blood samples were collected from young male athletes at rest, after each round (1st, 2nd, 3rd), and at 3, 5, and 10 minutes post-combat.
• Blood lactate concentrations ([Lac]B) were measured to evaluate metabolic response during and after simulated taekwondo fights.

Main Results:

• Blood lactate concentrations significantly increased after each round of combat compared to resting values.
• Lactate levels after the 3rd round were higher than those observed during the 3, 5, and 10-minute recovery periods.
• After 10 minutes of passive recovery, blood lactate levels were significantly lower than at 3 and 5 minutes post-combat and lower than after the 2nd round.

Conclusions:

• Taekwondo combat necessitates a high activation of the anaerobic lactic metabolic pathway.
• Young male taekwondo athletes exhibit an enhanced ability to rapidly clear blood lactate following intense combat.
• These findings highlight the significant physiological stress and adaptive capacity associated with taekwondo performance.
