Description
Background A better understanding of the physical activity behavior of individuals who undergo bariatric surgery will enable the development of effective post-surgical exercise guidelines and interventions to enhance weight loss outcomes. This study characterized the physical activity profile and physical function of 40 subjects 2–5 years postbariatric surgery and examined the association between physical activity, physical function, and weight loss after surgery. Methods Moderate-to-vigorous intensity physical activity (MVPA) was assessed with the BodyMedia SenseWear® Pro (SWPro) armband, and physical function (PF) was measured using the physical function subscale of the 36- Item Short Form Health Survey instrument (SF-36PF). Height and weight were measured. Results Percent of excess weight loss (%EWL) was associated with MVPA (r=0.44, p=0.01) and PF (r=0.38, p=0.02); MVPA was not associated with PF (r=0.24, p= 0.14). Regression analysis demonstrated that MVPA was associated with %EWL (β=0.38, t=2.43, p=0.02). Subjects who participated in ≥150 min/week of MVPA had a greater %EWL (68.2±19, p=0.01) than those who participated in <150 min/week (52.5±17.4). Conclusions Results suggest that subjects are capable of performing most mobility activities. However, the lack of an association between PF and MVPA suggests that a higher level of PF does not necessarily correspond to a higher level of MVPA participation. Thus, the barriers to adoption of a more physically active lifestyle may not be fully explained by the subjects’ physical limitations. Further understanding of this relationship is needed for the development
