Resistance training and hematological responses

Abstract

Aplastic anemia is a hematopoietic dysfunction that compromises pluripotent cells; the phenomenon that gives rise to the multiplication and maturation of the precursor or primordial cells of blood cells. It is commonly treated with immunosuppressive therapy and/or halogenic bone marrow transplantation. However, despite the comorbidities of aplastic anemia, studies associating physiological changes related to regular physical exercise are still scarce, possibly due to the low prevalence of the disease. Thus, we describe here the impact of a resistance training program on different hematological markers in a patient with severe aplastic anemia. A 39-year-old white male diagnosed with aplastic anemia 22 years ago underwent 12 weeks of resistance training. Different hematological markers were analyzed before and after 7 and 12 weeks of intervention. After the intervention an increase in reticulocytes and several other blood components were observed, the values of which remained within normal limits. In addition, there was a reduction in transaminases and liver enzymes that mark canalicular lesions, proving an improved liver condition. We conclude that after 12 weeks of strength training the patient presented positive changes in different hematological markers, such as erythrocytes, hemoglobin, hematocrit, neutrophils, and leukocytes, suggesting a positive effect of resistance training on the patient's clinical picture associated with the natural course of disease treatment.
