Abstract

The purpose of this study is to assess the impact of pre-surgery exercise training on cardiopulmonary fitness. Ten articles (six RCTs and four non-RCTs) involving 281 individuals were finally included in the synthesis. Regarding the effect on VO2 peak, overall standardized mean differences were 0.71 (95% CI, 0.31 to 1.11, n = 103) with heterogeneity (I2 = 0%, P = 0.49). For 6MWT, overall weighted mean differences (distance in meters) were 31.87 (95% CI, 27.84 to 35.89, n = 100) with heterogeneity (I2 = 0%, P = 0.96). Engaging in pre-bariatric metabolic surgery exercise training might improve anthropometric parameters and cardiopulmonary fitness with no significant changes in components of quality of life. However, considering high levels of heterogeneity, the results should be generalized cautiously.
