Anthropometric and electrolytic progression in a competitive period in elite judokas
The aim of the study was to evaluate the effects of the weight loss that judokas are subjected to before a competition on the homeostatic changes with regard to hematologic parameters and plasmatic electrolytes, as well as to analyze the correlation among these parameters. Seven elite judokas (20.7±...

| Resumo: | The aim of the study was to evaluate the effects of the weight loss that judokas are subjected to before a competition on the homeostatic changes with regard to hematologic parameters and plasmatic electrolytes, as well as to analyze the correlation among these parameters. Seven elite judokas (20.7±3.2 years; 72.8±15.9 kg; 170.8±10.3 cm) were selected. Anthropometric measurements and blood samples were obtained during a seven-week competitive period: 6 weeks before the competition (T1), 5 days before (T2), the day of the competition (T3), and two days after the competition (T4). The results show a statistically significant decrease in body weight, body fat percentage, and the residual mass of the judokas the day of the competition, as well as a significant increase in lymphocytes in T2, and a significant decrease in red blood cells, hemoglobin, and hematocrit throughout the competitive period. However, sodium and potassium did not demonstrate significant changes during the study, despite the fact that plasmatic chlorine increased in T2 and T3. Body weight was inversely related with the values of hematocrit and sodium, and it had a parallel relationship with potassium and chlorine. These results indicate that the rapid decrease in body weight in judokas before a competition bring along hematological changes to the organism, but it does not bring variations in the levels of plasmatic electrolytes, indicating a correct homeostatic regulation |
