Experimental group between the ages 23-66 n:21 (10 men, 11women) average of ages: 44,52 ±9.88 and control group n:25 (12 men, 13 women) average of ages: 43.68±10.93, totally 46 obese individuals joined in this study. Aerobic exercise program including 12-week of walking and running which is 4 days a week has been applied to the experimental group. Any exercise program hasn't been applied to the control group. In order to determine the body compositions, both groups have been measured with bioelectrical impedance analyzer (InBody230, InBody Co. Ltd., USA) a week before and a week later. In order to determine the life quality, test of SF-36 has been applied. For the analysis of data, the comparison of the binary groups, t-test has been applied after finding the differences between first test and the last test. For the comparison of the first test and the last test of each group, paired sample t-test has been applied. Our findings show that, when the first and the last test results of the experimental group are analyzed, statistically in a positive way a significant variation in the whole body composition and SF-36 life quality scale parameters has been detected (p<0.05). According to the first and the last test results of control group, while any significant difference hasn't been detected in the body composition parameters (p>0.05), decline in a negative way has been determined in the SF-36 life quality scale results (p<0.05). When the first and last test results of experimental and control groups are compared, a significant variation in the whole body composition parameters and sub-dimensions of SF-36 life quality scale on behalf i This study was presented under same title as the master thesis of Halil Rahman Başkılıç.

In conclusion, it can be said that 12- week of walking and running exercises affect body composition parameters and life quality of obese individuals positively. Keywords: obesity, body composition, life quality, exercise 1. Introduction Obesity is defined as excessive fat accumulation in tissues at a level that will create a risk for human health. Inactive lifestyle, physical inactivity, excess of nutrition and irregularity are the main factors of obesity. Nowadays, body mass index measurements are made to evaluate the obesity status and comments are made on the values obtained (Tekin et al., 2015). Factors causing obesity are genetic factors, age, gender, sedentary life and eating habits. According to data reported by the World Health Organization (WHO), there are 1.6 billion mild obesity and around 400 million obese people in the world. WHO has reported that these data will be updated to 2.3 billion mildly overweight and 700 million obese people in 2015 (Akbulut G, 2010). Obesity is classified 3 group according to body mass index, body fat distribution and fat cell. When examining health expenditures made in the south-east of America, Europe and Asia, total health expenditure reaches 15% for the treatment of the problems caused by obesity treatment and obesity in developed or developing countries in these regions. Much of these expenditures relate to psychological and physical disturbances caused by obesity (Altunkaynak and Özbek, 2006). Along with the increase in obesity, the risk rate for some diseases also increases. Obesity affects the body systems and psychosocial situation negatively and increases the risk of illness. The risk of heart and vascular diseases, diabetes, skeletal system problems, cancer types is increasing due to obesity (Özkan et al., 2013) According to the survey conducted by the Turkish Statistical Institute TUİK in 2008, 32.4% of the adult population is mildly overweight and 15.2% is obese. When we examined Turkey nutrition and health survey data in 2010, the frequency of being overweight in our country is 34.6% and the frequency of being obese is 30.3%. According to TÜİK 2 research data, 34.8% of the adult population is mildly overweight and 17.2% is obese (Altunkaynak and Özbek, 2006).

(Tekin et al., 2015). This study was conducted to investigate the effect of aerobic exercise on body composition and quality of life on obese subjects for 12 weeks.
