Physical activity (PA) has been in focus over the last two decades as a life style factor of importance. A review summarizing nearly 170 studies states that the scientific evidence for the association between lack of physical activity and cancer is convincing regarding breast and colon cancer and probable for prostate cancer and possible for lung and endometrial cancer (8). Regarding postoperative rehabilitation the benefits from preoperative physical exercise together with a postoperative early rehabilitation schedule has been reported for spinal surgery (9). In colorectal surgery the benefits of enhanced recovery programs have been clearly demonstrated (10). The impact of preoperative prehabilitation has been evaluated and seems beneficial (11, 12), however most studies have not used clinically important outcome measures such as complications or postoperative morbidity. The evidence for prehabilitation as a measure to reduce postoperative morbidity is scarce (12). To evaluate the recovery after a surgical procedure in a broader sense is difficult. Several scales have been tried to assess recovery (13-16).
