No relationship was identified between changes in weight and walking performance post-surgery .
Although physical activity performed after bariatric surgery is associated with enhanced weight loss outcomes , there is limited information on patients ' physical activity behaviour in this context .
This systematic review and meta- analysis assessed pre-operative to post-operative changes in physical activity and physical function outcomes among obese adults undergoing bariatric surgery .
Effects of aerobic exercise training on variability and heart rate kinetic during submaximal exercise after gastric bypass surgery – a randomized controlled trial
Background : This study aim ed to determine whether morbidly obese women have an alteration of heart rate ( HR ) kinetics and HR variability ( HRV ) during the 6-min walk test ( 6MWT ) and if an aerobic exercise training can modify these indexes after gastric bypass surgery ( GBS ) . Design and methods : Nineteen morbidly obese women were r and omized to a trained ( TG ) or control group and 12 women of eutrophic group ( EG ) were also evaluated . The obese women were tested on two occasions : 1 week before and 4 months after GBS through record of HR and R-R intervals during 6MWT for analysis HR kinetics . The TG underwent an aerobic exercise training program on a treadmill ( 1-h session , totaling 36 sessions over 12-week ) . Results : Both obese groups demonstrated a significant reduction of rMSSD and slower HR kinetics during the 6MWT when compared to the EG . In addition , only the TG demonstrated a significant improvement in HRV indexes , walking distance , faster time constant and mean response time of HR during 6MWT after training ( p < 0.05 ) . Conclusion : Morbidly obese women have slower HR kinetics and altered cardiac modulation during submaximal exercise . However , aerobic exercise training can produce beneficial adaptations in HRV and faster HR kinetics following GBS . Implication s for Rehabilitation The obesity is one of the most important threats to health in developed countries and bariatric surgery is an option for treatment of morbid obesity . Exercise is an effective means of improving health after this procedure due alterations of autonomic nervous system in this population . This study showed that a program of aerobic physical training after bariatric surgery was able to improve the kinetics of heart rate and the cardiac autonomic modulation , both evaluated during submaximal exercise
