Abstract
BACKGROUND: Poor functional exercise capacity is common among those with obesity; however, objective measures of exercise capacity are rarely examined in behavioral treatments targeting obese individuals. We examined whether a 4-week acceptance and commitment therapy (ACT) intervention for disinhibited eating or a behavioral weight loss (BWL) intervention improved exercise capacity and explored demographic and disinhibited eating variables related to exercise capacity. METHODS:Veterans (n = 61), randomized to receive ACT or BWL, completed an assessment of exercise capacity via the 6-min walk test (6MWT) at baseline and 6-month follow-up. Measures of disinhibited eating patterns and body mass index (BMI), at baseline and post-treatment, were also collected. Change in 6MWT distance and treatment group differences were examined using mixed ANOVAs. Characteristics related to baseline 6MWT and predictors of improvement in 6MWT at 6 months were examined with hierarchical multiple regression. RESULTS: There were overall significant improvements on the 6MWT from baseline to 6-month follow-up (F(1,59) = 11.14, p = .001, ηp2 = .159) but no differences between the ACT and BWL groups. Baseline BMI (β = - .33, p = .005) was the only variable related to baseline 6MWT. Improvements on the 6MWT were related to younger age (β = - .41, p = 0.001), female gender (β = .36, p = .001), and treatment-related increases in dietary restraint behaviors (β = .42, p = .001). CONCLUSIONS:Functional exercise capacity improved among participants completing behavioral interventions for weight and disinhibited eating. Improvements in dietary behavior regulatory skills may have generalized to improved regulation in other behavioral domains associated with exercise capacity.
