Obesity, which is one of the major health problems in both developed and developing countries today, is a health problem that occurs with an increase in adipose tissue when energy intake is higher than energy consumption and can cause social, psychological and serious medical problems. If current trends continue, it is reported that 70 million children may be obese and overweight by 2025 and obesity will be a leading health problem. Childhood obesity increases in the first year of life, between 5-6 years of age and during puberty. 1/3 of obese children and 80% of obese adolescents remain obese when they reach adulthood. On the other hand, it is known that 30% of adult obesity cases date back to childhood. It has been reported that obesity affects 10.9-20.0% of all children and adolescents. In a study involving 5206 school-age children (mean age 8.6±1.2 years, 50.2% boys) from seven European countries (Turkey, Bulgaria, Romania, Lithuania, Germany, Italy and the Netherlands), it was reported that the prevalence of obesity in Turkish children was 7.7%, the second highest in Europe after Romania. Obesity in childhood has many medical adverse effects on children. Obesity may cause problems such as rapid growth, early menstruation, increase in blood lipids, increase in heart rate and heart rate volume, fatty liver, impaired sugar metabolism, hypertension, increase in white adipose tissue, increase in serum irisin, myonectin, triglyceride, total cholesterol and leptin levels and decrease in omentin-1 levels. In studies conducted in obese and healthy children, it was found that triglyceride, total cholesterol, irisin, low density lipoprotein (LDL-C) and leptin concentrations were higher in obese children compared to healthy children and omentin-1 levels were lower. Considering that childhood obesity continues into adulthood and brings many problems, the importance of combating obesity in this period is clearly seen. Reducing calorie intake, increasing exercise and providing psychosocial support are very important in the fight against obesity. While exercise constitutes a part of the standard treatment of obesity, it has been reported to be more effective than diet because it increases energy expenditure. In studies conducted in obese children, it was found that planned and long-term moderate exercise increased serum irisin, myonectin, omentin-1 and HDL concentrations and decreased serum leptin, triglyceride, total cholesterol and LDL concentrations. It has also been reported that exercise reduces metabolic and cardiovascular complications and improves body composition, cardiovascular health and mental health. Despite the numerous benefits of exercise, it has been reported that regular exercise habits are low in obese children. It has been reported that obese children cannot exercise regularly due to reasons such as low motivation, parents' inability to spare time to spend time with their children, children who are overwhelmed between courses/courses in the exam marathon with career anxiety, lack of emotional support and inability to give up existing habits. In this direction, exercise that requires continuity in the management of childhood obesity can be made dynamic for obese children by using different approaches. Therefore, it is thought that structured exercise with augmented reality glasses (AR) that can respond to the reactions of the obese child will be more dynamic, improve metabolic and anthropometric values and prevent macrovascular complications that may develop in obese children. This study was planned as a randomized controlled experimental study to determine the effect of exercise with AR glasses on metabolic parameters and anthropometric measurement values in obese children aged 10-19 years.
