Abstract
The purpose of this study is to investigate the effect of aerobic and strength exercises on hematological parameters in sedentary women. To achieve the purpose of this study, a total of 23 volunteers including aerobic exercise group (AE, n: 10), strength exercise group (SE, n:13) were selected as participants. Two different exercises were applied for 4 days a week, throughout 16 weeks, within 60 minutes for each exercise with the intensity of heart rate (HR) 60-70 percent. The HR was measured using a heart rate monitor for each subject.The women's white blood cell (WBC), thrombocyte (PLT), red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT) and mean corpuscular volume (MCV) were measured before and after exercise. For statistical analysis, the Wilcoxon signed-rank test was used for intra-group evaluations, and the Mann Whitney U test was used for inter-group evaluations. After the exercise program, there were a meaningful decrease in the body weight and body mass index (BMI) the women in both intervention groups. In addition, in the hematological results of strength exercise group, some meaningful decreases were determined in the values of RBC, HGB, HCT and MCV (p<0.01). As a results, it was observed that regular aerobic and strength exercises can positively influence the body weight and BMI parameters of sedentary women. Along with this, a meaningful decrease has been found in the values of RBC, HGB, HCT and MCV of strength exercise group compared to aerobic exercise.

Summary
Blood is made up of an intracellular liquid (plasma) which has a major role of maintaining homeostasis (Isaac et al, 2013) and red blood cells, white blood cells, and platelets that are suspended in this liquid. The blood volume and hemoglobin amount increase with exercise. The hematological parameters can change, depending on the type, intensity and duration of the exercise (Çakmakçı, 2009; İbiş et al, 2010). Some researchers have found that some hematological parameters increase after regular exercises (Wardny et al 2008; Koushi et al, 2013; Kantyka, et al, 2015; Gnanou et al, 2014; Ceylan et al, 2014; Duzova et al, 2016), whereas some researchers have indicated that there is no change (Spiropoulos and Trakada, 2003; Çakmakçı, 2009)
