  • 摘要:Background and Study Aim: The aim of this study was to assess the concentration of blood lactate during the men's judo competition in order to investigate the impact of selected factors (the number and frequency of attacks and other variables) affecting it. Material and Methods: The study involved one professional judoist from the Sport Club (KS) of the Polish University Sports Association (AZS) Academy of Physical Education and Sport Gdansk, Poland (AWFiS) who is also a member of the national junior judo team. To determine the participant’s aerobic capacity, the test until exhaustion was performed during the tournament-specific preparation period. Additionally, anaerobic efficiency was measured in the Wingate Anaerobic Test (WAnT). Finally, blood samples were taken during an international junior judo tournament before and after each five fights as a material for the analysis of the concentration of lactate. Additionally, technical and tactical data of the five fights were recorded. Results: The highest concentration of blood lactate (25.1 mmol l-1) was observed after the fourth fight, whereas the lowest (9.8 mmol l-1) value was recorded after the last fight. The technical and tactical data have shown that the subject performed the highest number of attacks (10) in the first and fourth fight. Conclusions: According to our study, in-competition blood lactate concentration (as measured after each fight) exceeds the concentration obtained through the Wingate effort. This suggests that a single effort exerted during the WAnT is inadequate diagnostic index of glycolytic processes in tournament judo. Further, the frequency of attacks, numbers attacks, forceful attacks are not the only factors affecting glycolysis process
