Clinical Trial Summary

Severe/morbid obesity is an international public health issue that importantly increases the risk of cardiovascular events and cardiovascular and all-cause mortality. Likewise, severe/morbid obesity increases the risk of illness, reduces quality of life, and raises health-care costs. Bariatric surgery is the election method for the treatment of severe/morbid obesity, resulting in significant weight loss and remission of comorbidities. However, a relatively large proportion of bariatric patients regain weight and continue to be at high risk for cardiovascular disease and premature mortality. A healthy lifestyle following bariatric surgery is essential for optimizing and maintaining weight loss. Observational studies suggest that physical activity following bariatric surgery might be associated with additional weight loss and more effective weigh loss maintenance over time. However, very little experimental evidence exists regarding the effects of supervised exercise on obesity-related outcomes in this specific population.

The aim of the EFIBAR (Ejercicio FÍsico tras cirugía BARiátrica) randomized controlled trial is to determine the effects of a 16-week supervised concurrent (aerobic and strength) exercise intervention program on weight loss (primary outcome), body composition, cardiometabolic risk, physical fitness and quality of life (secondary outcomes) in patients with severe/morbid obesity following bariatric surgery.

According to the study aims the investigators pursue the following hypothesis: Supervised exercise will result in larger weight loss than control.
