Effects of Supervised Exercise on Body Composition in Patients Succeeding Bariatric Surgery 1 year Longitudinal Study

Abstract

This study aims to investigate whether a supervised, multicomponent exercise program can provide additional benefits on body composition after bariatric surgery. 18-65 year; body mass index (BMI) >35 kg/m2; 54 patients (Exercise Group 29; Control Group 25) who had mini gastric bypass or Gastric Sleeve Surgery were included in the study. A verbal suggestion was made to the CG to increase physical activity, but this suggestion was not taken into consideration. The exercise group participated in a supervised multicomponent exercise program, 3 days a week, nonconsecutively, lasting 60 minutes each, for 11 months, starting 1 month after surgery. All variables were tested with two-way ANOVA test according to the effect of exercises on body weight (BW), fat mass (FM), fat-free mass (FFM) and BMI. After completion of descriptive statistics (mean ± SD), an independent t test was used to examine between-group differences in anthropometric components at baseline. Accordingly, there was no significant difference between the groups at baseline, including age, BW, BMI, FM and FFM (p>.05). Both groups experienced significant initial BW and FM loss, but these changes did not differ significantly between groups (p>0.05). On the other hand, FFM changes showed significant differences between groups (p<.05). Although there was no statistical difference in BW, FM and BMI values of the exercise group and the control group in this study, the positive change in the FFM of the exercise group was found to be significant compared to the control group. This clearly shows the importance of exercise in our study. © The Author(s) 2023.
