The Effect of Pre-operative Exercise Intervention on Patient Outcomes Following Bariatric Surgery: a Systematic Review and Meta-analysis

Belinda J Durey et al. Obes Surg. 2022 Jan.

Abstract

This systematic review aimed to assess the effect of a pre-operative exercise intervention on short- and long-term health and clinical outcomes for adult patients undergoing bariatric surgery (BS). We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), SPORTDiscus and reference lists of relevant papers, through March 2021. Five randomised controlled trials were included (n = 199 patients). Modest increases in cardiorespiratory fitness (VO2max) were found at both pre-operative (0.73 mL kg-1 min-1, P ≤ 0.001) and maximum follow-up time points (0.98 mL kg-1 min-1, P ≤ 0.04). There was no significant effect of an exercise intervention on percentage total weight loss (%TWL). Pre-operative exercise can induce significant short- and long-term improvements in fitness in individuals with obesity. There is insufficient evidence to determine whether pre-operative training impacts other post-operative clinical outcomes.
