Objective: To assess the effects of a physical exercise program on the lipid profile, weight status and the cardiovascular health of obese candidates for bariatric surgery. Method: 22 morbidly obese patients participated in a 6-month physical exercise program. 16 formed the adherent group (attendance >= 80%; age: 37.81 +/- 11.90 years) and six the non-adherent group (attendance < 80%; age: 45.83 +/- 14.23 years). Before and 72 h after the last session were evaluated: weight, body mass index (BMI), contour waist, blood pressure, fasting, cardio respiratory fitness, cholesterol and triglycerides. Results: Weight, BMI and WC showed significant changes (p < 0.05) in both groups, with the results of the adherent group being better. In the adherent group, cardiorespiratory capacity (p = 0.001) was also increased, while diastolic pressure (p = 0.011), basal glycemia (p = 0.021) and triglycerides decreased significantly (p < 0.001). The non-adherent group did not present significant changes in these variables (p = 0.05). Conclusions: The intervention was feasible to perform without negative effects for the participants, and it is possible to recommend improving the cardiovascular health of these of patients.
