Effect of Aerobic Interval Training Before Gastric Bypass Surgery on Length Of Hospital Stay and Complications.

Obesity predisposes an individual to develop numerous comorbidities, including type 2 diabetes, and represents a major healthcare issue in many countries worldwide. Bariatric surgery can be an effective treatment option, resulting in profound weight loss and improvements in metabolic health; however, weight loss following gastric bypass surgery (GBS) is widely variable. Physical activity (PA) participation can improve these results. Exercise is an excellent way to improve health, with well-characterized physiological and psychological benefits. In the present paper we review the evidence to determine whether there may be a role for exercise as a complementary adjunct therapy to gastric bypass surgery. The purpose of the study was to investigate aerob interval training (AIT) vs control group’s impact on hospital length of stay (LOS), complications and weight loss after GBS. Methods: Forty tree participants (22) underwent GBS at Ålesund and St.Olavs Hospital. Height, weight, waist circumflexes, peak oxygen consumption (VO2peak), respiration exchange ratio (RERmax), body mass index (BMI) were assessed at baseline, pre-op and 6 months after surgery. The participants were divided into two groups, one control group and one AIT group. The AIT group trained two times a week before surgery. Results: There is a tendency of fewer LOS in the AIT group, which had 14% lower LOS than the control group. Still we could not find any significant numbers. AIT- and control group had the same number of complications. Conclusion: In this assessment of the predictive utility of CPET variables in obese patients, we found a slight tendency that VO2peak, is associated with postoperative hospital LOS. But since other studies have found this association, there are reasons to continue the research. Additional randomized controlled exercise trails are needed as the next step to more clearly define the potential for exercise to provide additional health benefits and LOS.
