Obesity is a growing problem worldwide and its prevention has become one of the leading priorities for the World Health Organisation. Obesity results from chronic imbalance between energy intake and energy expenditure. Although early prevention of obesity is preferable, surgical treatment is often required for severely obese people.
Bariatric surgery has been shown to be the most effective therapy for severe obesity. Weight loss following bariatric surgery results in significant improvements in coexisting comorbidities, such as diabetes and hypertension but there is controversy whether bariatric surgery also improves aerobic capacity.
The purpose of this study is to investigate the effects of bariatric surgery on cardiopulmonary function and on daily physical activity. It is hypothesized that bariatric surgery will improve aerobic capacity and result in beneficial lifestyle changes from sedentary to more active.
6,296 studies on the registry are indexed under Obesity; 1,692 are open to participants now.

Exclusion Criteria:
Cardiorespiratory function assessed by peak oxygen consumption (VO2peak)
Time frame: One to two weeks before surgery and six months after surgery
Lung function
Lung function will be assessed by spirometry and body plethysmography
Time frame: One to two weeks before surgery and six months after surgery
Heart function
Echocardiography will be performed to assess heart function.
Time frame: One to two weeks before surgery and six months after surgery
Inspiratory muscle strength
Maximal inspiratory pressure and sniff nasal pressure will be recorded.
Time frame: One to two weeks before surgery and six months after surgery
Peripheral muscle strength
Maximum isometric strength of hand/ forearm, quadriceps and hip flexors muscles will be evaluated
Time frame: One to two weeks before surgery and six months after surgery
Free living sedentary and physical activity times
Daily physical activity habits will be assessed by an accelerometer and International Physical Activity Questionnaire: Long (IPAQ-Long). Participants will be required to wear the accelerometer for four consecutive days during the two study points.
