The primary aim of this study is to investigate whether an intervention including individual coaching to improve level of physical activity before and after gastric bypass surgery leads to a changed of level physical activity post-operatively at eight weeks, one and two years. Secondary aims of the study are to investigate whether increased physical activity has effects on complication rates, re-admissions and re-operations, post-operative weight-loss, gastrointestinal pain, recovery measured as hospital stay, sick-leave and QoL, resumption of normal physical activity. METHODS 300 patients will be recruited and randomized to an intervention group or control group. The patients in the intervention group will receive individual coaching by a physical therapist to: * increase physical activity 30 minutes/day (At least 150 min/week) * decrease time spent sitting/lying The patients in the control group will receive standard care. Before surgery, 6 weeks, and one year after surgery patient will fill in a questionnaire including level of physical activity, sick leave, quality of life and gastrointestinal pain. In addition blood test will be taken and complication rates recorded. ## Eligibility - **Sex:** ALL - **Healthy Volunteers:** No ``` Inclusion Criterion: \- Patients at including hospitals scheduled for gastric bypass surgery Exclusion Criteria: * Inability to understand given information. * Inability to perform the intervention ``` ## Arms - **Increased physical activity** (EXPERIMENTAL) — Increased physical activity daily before surgery. Standard care during hospital stay and continued training after discharge. - **Standard care** (OTHER) — Standard care ## Interventions - **Increased physical activity** (OTHER) — Preoperatively Individual coaching by a physical therapist to: * increase physical activity 30 minutes/day (At least 150 min/week) * decrease time spent sitting/lying Telephone follow up one week after the intervention starts At the hospital -Frequent mobilization After discharge A telephone follow up one week postoperatively with coaching by a physical therapist to: * increase physical activity 30 minutes/day (At least 150 min/week) until 8 weeks postoperatively * decrease time spent sitting/lying The intervention includes a prescribed FaR (Fysisk aktivitet på recept) with frequency, duration and intensity of the activity corresponding 12-15 on the BORG-RPE scale. - **Standard care** (OTHER) ## Primary Outcomes - **INTERNATIONAL PHYSICAL ACTIVITY QUESTIONNAIRES (IPAQ)** _(time frame: From inclusion 1 year postoperatively)_ — Physical activity level measured in METS (Metabolic Equivalent) - **Saltin-Grimby Physical Activity Scale (SGPAS)** _(time frame: From inclusion to 1 year postoperatively)_ — Physical activity level, 1-4 (4 highest activity level). ## Secondary Outcomes - **Complication rates** _(time frame: From inclusion to 30 days postoperatively)_ - **Length of stay** _(time frame: From surgery to discharge.
