Introduction: Menstruation leads to bleeding and anemia; while endurance training causes erythropoiesis and stimulates hematopoiesis; therefore, this study was performed with aim to evaluate the effects of 6 weeks aerobic exercise training on blood hematological factors in adolescence girls. Methods: This semi-experimental study was performed on 20 girls aged 11-12 years old in 2014. The subjects were randomly enrolled in two groups (Experimental and Control). Experimental group performed aerobic exercise for three sessions per week for six weeks. The control group continued the usual daily activities. Before and after the exercise programs, complete blood count (CBC; using the blood samples) and maximum oxygen uptake (VO2max; using 1600 meters running and walking) were measured. Data analysis was performed by SPSS software (version 16) and dependent and independent t-test, Kolmogorov Smironov, and Shapiro-Wilk tests. PResults: Increase of VO2max was significant after exercise in experimental group (P=0.018). The value of RBC, HGB, and HCT significantly increased after exercise in two groups (P<0.05). In addition, the value of MCH and MCHC significantly decreased after exercise in control group (P<0.05). The value of WBC significantly increased (P=0.01) and MCHC significantly decreased (P<0.05) in control group and experimental group, respectively. However, comparisons between groups were statistically significant only in VO2max at post-test (P=0.033). No significant difference was observed in other hematological factors (PLT, MCV) in two groups (P>0.05). Conclusion: Six weeks of aerobic exercise are significantly effective in VO2max without significant changes in other hematological factors in adolescence girls.
