Study: NCT01893580

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Experimental: 1. Experimental
Description: Home-based exercise pre surgery and postoperative exercise in a team initiated two weeks after surgery. Intervention consists of:~1. Preoperative home-based exercise program - cardiovascular exercise of moderate-vigorous intensity for at least 30 minutes every day until surgery.~2. Postoperative rehabilitation: A supervised 12-week rehabilitation program containing 24 group-based exercise sessions, three individual counseling sessions and smoking cessation, nutritional counseling or patient education, this is offered too.The cardiorespiratory intensity is at \~50-60% of individual HRmax for the first four weeks and increases to moderate-high intensity at \~70-90% of individually determined HRmax. The intensity of the strength exercise program is at \~60-80% of 1 RM.

Description: Early postoperative exercise in a team initiated two weeks after surgery. Intervention consists of:~Postoperative rehabilitation: A supervised 12-week rehabilitation program containing 24 group-based exercise sessions, three individual counseling sessions and smoking cessation, nutritional counseling or patient education, this is offered too.The cardiorespiratory intensity is at \~50-60% of individual HRmax for the first four weeks and increases to moderate-high intensity at \~70-90% of individually determined HRmax.

Group type: OTHER
Intervention: Other: 4. Usual care
Description: Exercise in a team initiated six weeks after surgery consisting of a supervised 12-week rehabilitation program containing 24 group-based exercise sessions, three individual counseling sessions, and three group-based lessons in health-promoting behavior. If the participants have special needs in terms of smoking cessation, nutritional counseling or patient education, this is offered too.~The cardiorespiratory intensity is at \~50-60% of individual HRmax for the first four weeks. The next eight weeks the intensity increases to moderate-high intensity at \~70-90% of individually determined HRmax. The intensity of the strength exercise program is at \~60-80% of 1 RM.
