RESUMO
BACKGROUND: In recent years, the pandemic explosion of obesity has led to the definition of a pre-eminent therapeutic role for bariatric surgery, confining physical activity to a success parameter of surgery rather than a primary prevention measure. The aim of this study is to evaluate the role for aerobic physical activity (road running) in strengthening the metabolic and psychosocial effects of bariatric surgery. METHODS: Ten patients who underwent gastric bypass for morbid obesity were submitted to an intensive program of road running training, aimed at completing a 10.5-km competition in September 2013. Inclusion criteria included age (<50), BMI (<35), suitability for sport activity, and good compliance. A cohort of 10 patients excluded for logistical issues were enrolled as a control group. During the training period, patients were submitted to biometrical, sport performance, cardiopulmonary, metabolic, and psychiatric evaluations. RESULTS: Protocol adherence was 70 %; no physical injury was registered among participants. More than weight loss (BMI 29.3 to 27.1), the runners experienced a redistribution of body mass with significant differences in fat percentage and waist/hip ratio. Participants had a significant running performance improvement and, differently from the controls, a significant amelioration of echocardiographic and cardiopulmonary parameters, predicting a reduction in cardiovascular risk. Psychiatric evaluation underlined a tendency to a reduction in anxiety, depression, and general psychopathology symptoms. CONCLUSIONS: Road running seems to have an important supporting role in boosting bariatric surgery results. The utilization of monitored and regulated training programs represents a fundamental prerequisite to achieving satisfactory results and patient compliance.
