Résumé

Background
Experts recommend physical activity (PA) to optimize bariatric surgery (BS) results. However, evidence on the effect of PA before BS is missing. The aim of this study was to assess the impact of adding a Pre-Surgical Exercise Training (PreSET) to an interdisciplinary lifestyle intervention on physical fitness, quality of life, PA barriers, and anthropometric parameters of subjects awaiting BS.

Methods
Thirty candidates for BS (43.2 ± 9.2 years, 47.5 ± 8.1 kg/m2) have been randomized in two groups: one group following the PreSET (endurance and strength training) and another receiving usual care. Before and after 12 weeks, we assessed physical fitness with a battery of tests (symptom-limited exercise test, 6-min walk test (6MWT), sit-to-stand test, half-squat test, and arm curl test), quality of life with the laval questionnaire, and PA barriers with the physical exercise belief questionnaire.

Results
One control group subject abandoned the study. Subjects in the PreSET group participated in 60.0 % of the supervised exercise sessions proposed. Results showed significant improvements in the 6MWT (17.4 ± 27.2 vs. −16.4 ± 42.4 m; p = 0.03), half-squat test (17.1 ± 17.9 vs. −0.9 ± 14.5 s; p = 0.05), arm curl repetitions (4.8 ± 2.3 vs. 1.0 ± 4.1; p = 0.01), social interaction score (10.7 ± 12.5 vs. −2.1 ± 11.0 %; p = 0.02), and embarrassment (−15.6 ± 10.2 vs. −3.1 ± 17.8 %; p = 0.02) in completers (n = 8) compared to the non-completers (n = 21). No significant difference between groups in BMI and other outcomes studied was observed after the intervention.

Conclusions
Adding a PreSET to an individual lifestyle counselling intervention improved physical fitness, social interactions, and embarrassment. Post-surgery data would be interesting to confirm these benefits on the long term.
