Introduction: Obesity has been considered a
global epidemic and a serious public health problem closely related to other
diseases. Moreover, obese individuals have limitations in physical capacity and
pulmonary function. Weight loss induced by bariatric surgery appears to help
reverse this situation. However, questions about physical capacity and lung
function, and its relationship with body composition remain to be clarified.
Objective: To evaluate the physical capacity, body composition and lung
function in women undergoing bariatric surgery. Methods: Twenty five women who
underwent bariatric surgery between 6 and 24 months ago, and 10 non-obese women
were evaluated for exercise capacity by the six minutes walk test (6 MWT), body
composition by bio-electrical impedance analysis and lung function by spirometry
and measurement of maximal static respiratory pressures. Results: Subjects with
BMI <30 kg/m2 were found to have better physical performance, demonstrated by increased 6 MWT
distance, not differing from non-obese women. When compared with non-obese
women, there were no significant differences in body composition and lung function.
Higher BMI was correlated with shorter distances in 6 MWT. Conclusion: 6 to 24
months after surgery, when the weight loss of patients who underwent bariatric
surgery reaches levels considered non-obese, it provides improvement in physical
performance to a level similar to that of
non-obese patients.
