摘要：The aim of the work was to assess the intensity of purine nucleotide degradation during maximum physical exercise. 5 elite female boxers were the subject of the study. Each of them underwent two exercise stress tests in order to evaluate the level of V̊O2peak and the level of anaerobic capacity during a Wingate test. The study involved collecting capillary and venous blood samples at rest and after the exercise test to determine the Acid-Base Balance (ABB),concentration of lactic acid (LA) and purine metabolism nucleotides. The average value of V̊O2peak was 40.92 (SD = 4.087) ml/kg/min,the average anaerobic capacity Ppeak was 7.57 (SD = 0.380) Watt/kg. The workload resulted in significant changes in the level of ABB and LA after both of the exercise stress tests (p < 0.001). Concentrations of hypoxanthine (Hx),xanthine (X) and uric acid (UA) in the blood increased significantly after the Wingate test (p < 0.05). The level of plasma purine nucleotides at rest and after standard exercise may be a useful tool for monitoring the adaptation of energetic processes in different training phases and support the overload diagnosis.
