abstract={This paper will treat about hematological parameters in Brazilian Jiu Jitsu athletes, linking their training with some variations of these parameters. The aim of this study was to evaluate the potentialities of this sport modality in what it has to do with promotion and maintenance of human health. Fourteen athletes have participated in this study that consisted in accompanying them during their training for six months, when monthly blood samples were collected and weekly monitoring of heart rate training were done. Variations in hematological parameters have been compared with the intensity of the training performed all this long. Statistical analyzes performed were Student t test for paired samples when data showed a normal distribution, and Wilcoxon test for paired samples, when data didn't show a normal distribution. Results show that erythrocytes and lymphocytes varied in a very similar way to the intensity of training. Hemoglobin, hematocrit, total leukocytes, neutrophils and platelets varied oppositely to training intensity. RDW, monocytes and eosinophils varied randomly, with no relation to the intensity of training. The training stimulates an increase in the production of red blood cells and hemoglobin, however, the kind of intense training and full contact, with frequent injuries, might cause hemolysis, maintaining low concentrations of these parameters. Jiu Jitsu promotes specific effects both in the red data series as in white ones; and it can be recommended for health maintenance, since, despite the detected variations, all parameters remained under the reference values.},
