The study is aiming to demonstrate the benefits of weight loss following an individualized interval exercise training programme and dietary recommendations on quality of life in young obese patients. Material and method: We conducted a 6 months prospective study on 28 young obese patients (mean age 21.3±2.1 years; mean weight 83,66±20,65). Patients were evaluated at baseline and after 6 months of intervention trough cardiopulmonary exercise testing (using Cortex Metalyzer 3B system), body composition, (lnBody720), and quality of life assessment (SF36 questionnaire). Interval training consisted in 50 minutes sessions, 3 times per week, at intensive endurance training zone (in the range of anaerobic threshold), completed by 1 minute interval in the range between anaerobic threshold and respiratory compensation point, for every 5 minutes of training. IET was supervised and guided by physical therapist. For exercise intensity and caloric consumption monitoring we used Polar RS 800 heart rate monitors. Pedometers were also used in order to achieve 6000 steps/day , in those days in which they also participated in physical training, and 10000 in days without physical training. General dietary recommendations were given to the patients in order to improve their nutritional habits and reduce caloric consumption. Al subjects received a individula recommendations for increasing the daily physical activity level. Results: At the end of the study we observe significant decrease of weight from 83.66±20.65 kg at 81.58±19.85kg, and increase of V02 max from 1.83 ±0.33 l/min to 1.93±0.33 l/min. Regarding life quality – Physical Component Summary increased from 47.88±6.92 to 51.32±6.22, (p=0.01) and Mental Component Summary increased from 47.97±7.28 to 53.42±6.28 (p=0.01). Conclusions: 6 months of weight loss programe based on general dietary recommendations and physical training can decres weight and significantly improve health related quality of life.
