Effects of physical exercise on sarcopenia after bariatric surgery: Study protocol of a randomized controlled trial
Cláudia Amaro Santos, Armando Raimundo, Manuel Carvalho, Sandra Martins
Introduction: Bariatric surgery is the treatment of severe obesity with associated pathologies, with
proven evidence in its benefits. By treating overweight allows a better and even reversal of pathologies
associated with obesity. Weight loss associated with bariatric surgery is greatly associated with a
significant reduction of skeletal muscle and bone mineral mass, which leads us to induce that after
bariatric surgery, patients incur an increased risk of sarcopenia. The need for prophylactic programs that
prevent sarcopenia in bariatric surgery patients seems to be one of the crucial points for the framing of
long-term surgical success of bariatric and metabolic surgery. The aim of this randomized clinical trial
will be to study the effects of a 16-week supervised exercise intervention program on the prevention of
sarcopenia after bariatric surgery
Method: This randomized controlled trial study will include 60 patients of both sexes on the waiting list
for bariatric surgery and who have subsequently performed the surgery. They will be randomized into 2
groups, experimental and control. The intervention will take place 1 month after surgery, for a total of 16
weeks. Parameters of body composition, metabolic risk, quality of life, physical activity and sedentary
behavior will be determined.
Results: Assessments will take place in five moments, the surgery, the intervention, the post-intervention,
six months after the intervention, twelve months after the intervention.
