Understanding the Capacity for Exercise in Post-Bariatric Patients

The aim of this study is to conduct a pilot randomized trial testing an exercise program specifically adapted for post-bariatric patients. A total of 51 post-bariatric patients, 6-24 months post-surgery, were randomly assigned to usual care control (n = 25) or the exercise intervention (n = 26). The intervention included twice weekly 60-min group exercise classes with functional strength, flexibility, and aerobic activities; at least 3 days per week of self-directed exercise; daily pedometer; recording of steps and activities; and weekly telephone counseling. There was also a 6-month maintenance period. Patients were 49 +/- 12 years old, 84 % female, 59 % non-Hispanic white, with a BMI of 32.9 +/- 5.7 kg/m(2) and percent excess BMI loss since surgery of 56 +/- 35 %. Patients were 14 +/- 5 months post-surgery. A total of 44 patients (86 %) completed both phases of the program and all assessments. The following measures improved significantly for intervention participants with no significant change in control participants: yards walked in 6 min, seconds for 8-foot up-and-go, number of arm curls, and distance in inches for chair sit-and-reach. Intervention changes remained after 6 months of maintenance. When compared to patients in usual care, a specially adapted exercise program for post-bariatric patients resulted in significant improvements in objectively monitored health outcomes. This program was delivered in a clinical setting and could be implemented in a variety of settings to improve health outcomes for post-bariatric patients.
