This study was to investigate the effects of boxing competition on hematological indices and morphological change of erythrocyte at pre, post- boxing competition and recovery 60 min periods. Ten volunteer male amateur boxer were investigated. Blood samples were collected at prior, immediately after exercise and recovery 60 min. Red blood cell count(RBC), hemoglobin(Hb), and hematocrit(Hct) were measured by an automatic blood cell counter(Abx Micros 60). Blood cell morphological erythrocyte were evaluated in Wright`s stained blood films. The present results were as follows: There was significant increase RBC, Hb, and Hct at post-boxing game compared to pre-boxing game and significant decrease at recovery 60 min. There was significant increase ESR and abnormal erythrocyte at post- boxing game compared to pre-boxing game and significant decrease at recovery 60min, however, were significantly higher than pre-boxing game. In the present results, it can be suggested that acute boxing competition can influence hematological variables and induce oxidative damage to erythrocyte.
