Abstract Resume

Background: Beyond the deleterious effects of adiposity in the individuals’ physical health, the obesity predisposes to the development of psychological disorders that affect
negatively in the perception of quality of life (QOL) of obese patient. It is believed that multidisciplinary interventions are ideal for obesity treatment. However, the exercise intensity to be
recommended is still not well established, especially when the objective is improvements in QOL. The objective of this study is verify the effect of different intensities of aerobic exercise training
on the quality of life of obese adolescents submitted to short (12 weeks) and long term (24 weeks) multidisciplinary intervention. Methods: The study included pubescent obese
adolescents (34.72±4.10 kg) of both sexes, aged 14.85±1.44 years. The adolescents were submitted to 24 weeks of multidisciplinary intervention composed by exercise training (3x per week), nutritional
therapy (1x per week), psychological counsenling (1xper week) and clinical monitoring (1x per month). After the voluntaries selection, they were allocated in three groups: High Intensity Training
Group (HITG) (N=31), Low Intensity Training Group (LITG) (N=31) and Control Group (CG) (45). Measures of body composition were conducted applying absorptiometry technique of dual beam x-ray (DEXA);
and QOL was assessed by the Short Form Health Survey (SF-36). The measurements have been made at different times: baseline, 12 and 24 weeks of intervention. Results: Eleven weeks were
enough to realize body fat percentage (BF%) reduction (p<0.001) and lean mass (LM) (kg) raise (p<0.001) in the HITG, LITG, and CG. Additionally, there was a decrease in body mass index (BMI) (kg/m²)
only in experimental groups (EG) (LITG p<0.001; HITG p=0.049). After 24 weeks of intervention, BM increased only in the CG without changes in the HITG and LITG. For all other variables the changes
observed at 12 weeks were maintained at 24 weeks. In relation to the domains of QOL, there is improvement in the perception of Physical Function (PF) in HITG and LITG after 12 weeks without
differences between the effect size between groups (HITG d=0.747; LITG d=0.782) when compared to the CG. The HITG also improved in the perception of General Health (GH) (p=0.014) and Media General (p=
0.002) domains with a moderate effect for both (d=0.713, d=0.535, respectively), compared to the CG. When 24 weeks were observed, the adolescents submitted to the multidisciplinary intervention
continued to positively realize the PF the same way as in 12 weeks. The analysis of the percentage variation of the QOL domains suggests that more pronounced changes happened in response to the HITG
when compared to GC and LITG, and the effects are intensified after 24 weeks of multidisciplinary intervention. Conclusions: The multidisciplinary intervention produces positive
changes in the body composition, regardless of the intensity of aerobic training. However, the findings suggest that high intensity exercise produces more pronounced effect on the QOL of obese
adolescents when compared to low intensity training, and this fact has been associated in more domains of QOL.
