摘要:This study aimed to compare the red blood profiles’ that are determinants of oxygen transports system, of elite wrestlers with sub-elite wrestlers. This study consists of a twenty-one elite wrestlers representing national team of Turkey who volunteered to participate in the study. Biochemical parameters were determined during transition period and the bloods were drawn in a resting state for each participant. A paired T tests was used to check the variations in hematological parameters. There are no significant differences between the groups except age. Elite wrestlers age was found to be significantly higher than sub elite wrestlers (p = 0.019 <0.005). RBC, HGB, HCT, MCH, MCHC were within normal limits and also for athletes indicates a positive development and there were no significant differences between the groups. Training increases total hemoglobin mass by stimulating erythropoiesis, which increases the amount of O2 that can be carried by blood. regular screening of hematological variables is desirable as many athletes have values near or below the lower limit of the normal range.
