“…Peak VO 2 relative to body weight was importantly increased in all studies where it was reported [23-25, 28], but without indicating the amount of weight loss that is significant. In addition, in previous studies major postoperative increases in physical activity were seen after sleeve gastrectomy, and these findings were associated with greater weight loss and improved quality of life [36, 37]. The same outcome was observed in our study population but after RYGB surgery.…”

Background: Bariatric surgery, especially Roux-en-Y gastric bypass (RYGB), has become the most frequently used therapy for morbid obesity. Objectives: The aim of this study was to examine the effects of surgically induced weight loss on cardiopulmonary function 6 months after the procedure, as well as the effect of such an intervention on well-known risk factors for cardiovascular diseases. Methods: This is a cross-sectional study on 66 morbidly obese patients (BMI ≥40 or ≥35 kg/m² with present comorbidities), comparing their cardiopulmonary function prior to and 6 months after RYGB surgery. Results: The substantial amount of weight loss (29.80 ± 13.27 kg) after RYGB surgery was associated with significant reduction of comorbidities, especially diabetes and sedentary lifestyle (p = 0.005 and p = 0.002, respectively). Regarding functional capacity, there was significant increase in peak oxygen uptake (VO₂ peak, p = 0.003), duration of exercise testing, metabolic equivalents (exercise time and METs, p < 0.001), and in peak O₂ pulse. These findings were particularly pronounced in a group of patients who had lost more than 18% of initial weight. Conclusions: Reduction of body weight after RYGB surgery is associated with significantly improved cardiorespiratory function 6 months after surgery, especially in patients who lost more than 18% of their initial body weight. In addition, substantial decreases in body weight were also associated with a reduction of cardiovascular risk factors such as diabetes, smoking, hypertriglyceridemia, and sedentary lifestyle.

“…Our data highlight the need for additional randomized controlled exercise trials to better understand the implications of components of exercise prescription (dose, duration, intensity) on long-term weight loss maintenance and health in RYGB surgery patients. Increased physical activity after bariatric surgery has been reported to provide additional weight loss (43). However, most of these studies were nonrandomized, retrospective, and observational in nature and measured physical activity by questionnaire and self report (43), methods that may lead to overestimation of exercise participation in obese subjects (44,45), including those who have undergone bariatric surgery (29).…”

Our observations using a semi-supervised exercise intervention are in line with those of Shah et al, who showed that a high-volume exercise prescription following bariatric surgery had no impact on body weight and waist circumference when patients were compared with a control group (20).…”

nondiabetic patients following RYGB surgery are typically quite modest compared with the presurgery condition (3). Moreover, there appear to be 2 discrete periods of improvement. The first is immediately after surgery, at which time hepatic, but not peripheral, S I improves in response to acute energy restriction (4-6), while greater, protracted weight loss appears to be more strongly associated with improved peripheral S I (7,8). Even with significant weight loss 1 year following RYBG surgery, peripheral S I is still low compared with that of lean metabolically healthy individuals (3,5,6,9).Exercise is considered a cornerstone for obesity treatment, and while it is not generally viewed to cause substantial body weight reduction (10), it can potently improve peripheral S I and glucose control (11-13) and can reduce the risk of T2D and cardiovascular disease (14,15). There is general consensus that even a single session of moderate intensity exercise can induce an improvement in S I (16). There is also evidence that exercise can BACKGROUND. Roux-en-Y gastric bypass (RYGB) surgery causes profound weight loss and improves insulin sensitivity (S I ) in obese patients. Regular exercise can also improve S I in obese individuals; however, it is unknown whether exercise and RYGB surgery-induced weight loss would additively improve S I and other cardiometabolic factors. METHODS.We conducted a single-blind, prospective, randomized trial with 128 men and women who recently underwent RYGB surgery (within 1-3 months). Participants were randomized to either a 6-month semi-supervised moderate exercise protocol (EX, n = 66) or a health education control (CON; n = 62) intervention. Main outcomes measured included S I and glucose effectiveness (S G ), which were determined from an intravenous glucose tolerance test and minimal modeling. Secondary outcomes measured were cardiorespiratory fitness (VO 2 peak) and body composition. Data were analyzed using an intention-to-treat (ITT) and per-protocol (PP) approach to assess the efficacy of the exercise intervention (>120 min of exercise/week).RESULTS. 119 (93%) participants completed the interventions, 95% for CON and 91% for EX. There was a significant decrease in body weight and fat mass for both groups (P < 0.001 for time effect). S I improved in both groups following the intervention (ITT: CON vs. EX; +1.64 vs. +2.24 min -1 /μU/ml, P = 0.18 for Δ, P < 0.001 for time effect). A PP analysis revealed that exercise produced an additive S I improvement (PP: CON vs. EX; +1.57 vs. +2.69 min

“…In a systematic review 15 of 17 observational studies suggest that exercise is associated with greater weight loss following bariatric surgery [2]. Besides the increased weight loss effect it has also been shown that regular physical activity decreases mortality in obese persons [3].…”

Background and purpose: Obesity is a major global health problem today and the only evidence-based method leading to a long-lasting weight reduction is bariatric surgery. Physical activity improves health, decreases the incidence of several diseases and may influence weight loss outcome after bariatric surgery. Knowledge regarding how patients experience physical activity after bariatric surgery could provide us with better tools to enhance physically active. Methods:The aim of the present study was to describe how patients experience physical activity one year after bariatric surgery. An inductive qualitative content analysis was used to analyse semi-structured interviews with twenty-four patients one year after bariatric surgery. Results:The main findings emerged in four overarching themes: "Hindrances of physical activity", "Physical activity with a less obese body implies achievement", "Coming to an understanding of the benefits of physical activity" and "Need of support". Conclusion:According to our findings patients experience both achievements and hinders with regard to physical activity one year after surgery. Patients had an increased understanding of the benefits of physical activities, but support appears necessary to obtain and maintain a suitable level.
