    Abstract The purposes of this systematic review and meta-analysis of peer-reviewed literature were to examine the chronic effects of resistance training with blood flow restriction (RT-BFR) on hemodynamics, and to compare these adaptations to those induced by traditional resistance training (TRT) programs in adults (PROSPERO: Registry: CRD42022339510). A literature search was conducted across PubMed, Sports Discus, Scielo, and Web of Science databases. Two independent reviewers extracted study characteristics and blood pressure measures. Risk of bias (The Cochrane risk of bias tool for randomized controlled trials [RoB-2]), and the certainty of the evidence (Grading of Recommendations, Assessment, Development, and Evaluation [GRADE]) were used. A total of eight studies met the inclusion criteria for systolic (SBP), diastolic (DBP), and mean arterial pressure (MAP). Regarding the comparison of RT-BFR

    Abstract Purpose of review: The purpose of this review and meta-analysis is to characterize the changes in body composition of children and adolescents who underwent bariatric surgery and identify possible negative effects of performing this procedure during pediatric ages.
    Recent findings: Bariatric surgery in children and adolescents is an emerging strategy to promote higher and faster body weight and fat mass losses. However, possible negative effects usually observed in surgical patients' muscle-skeletal system raise a major concern perform this intervention during growth. Despite these possible issues, most experimental studies and reviews analyze bariatric surgery's effectiveness only by assessing anthropometric outcomes such as body weight and BMI, disregarding the short- and long-term impact of bariatric surgery on all body composition outcomes. Bariatric surgery is effective to reduce fat mass in adolescents, as well as body weight, waist circumference, and BMI. Significant reduction in lean mass and fat-free mass is also observed. Bone mass seems not to be impaired. All outcomes reduction were observed only in the first 12 months after surgery. Sensitivity analysis suggests possible sex and type of surgery-related differences, favoring a higher fat mass, body weight, and BMI losses in boys and in patients who underwent RYGB.

    Abstract Purpose: This study examined the benefits of an 11-months multicomponent exercise program (MEP) on muscular strength (MS) after bariatric surgery.
    Methods: Of the 84 randomized patients, 41 participants from the exercise group (EG) and 20 participants from the control group (CG) were included in the analysis. The EG received supervised MEP for 11 months, starting 1-month post-bariatric surgery (BS) in addition to standard medical care, while the CG received medical care recommendations only. Knee and trunk MS was assessed by isokinetic dynamometry pre-surgery, 1-, 6-, and 12-month post-surgery, while body composition was assessed by dual-energy X-ray absorptiometry.
    Results: The MEP did not significantly impact absolute MS in the dominant knee and trunk regions at 6- and 12-month post-BS. However, relative MS showed significant improvements. At 6-month post-BS, knee flexion at 60°/s relative to body weight (BW) increased significantly (p = 0.047), as did knee extension at 180°/s relative to BW (p = 0.009), and knee extension at 60°/s relative to total lean mass (p=0.040). At 12-month post-BS, knee flexion at 60°/s relative to BW also significantly improved (p=0.038).
    Conclusion: While absolute MS was not significantly improved with MEP, this study found significant enhancements in relative MS, particularly in dominant knee flexion post-MEP participation. Further research should explore different exercise intensities and frequencies to optimize postoperative MS recovery post-BS.

    Abstract BACKGROUND: Bariatric surgery is the most effective treatment for patients with severe obesity, but success rates vary substantially. Exercise is recommended after bariatric surgery to reduce weight regain but the effectiveness remains undetermined on weight loss due to conflicting results. It is also unclear what should be the optimal exercise prescription for these patients. A systematic review and meta‐analysis of randomized controlled trials on the effects of exercise on body weight (BW), anthropometric measures, and body composition after bariatric surgery was performed. METHODS: PubMed/MEDLINE®, EBSCO®, Web of Science® and Scopus® databases were searched to identify studies evaluating exercise effectiveness. RESULTS: The analysis comprised 10 studies (n = 487 participants). Exercise favored BW (−2.51kg; p = 0.02), waist circumference (−4.14cm; p = 0.04) and body mass index (−0.84kg·m⁻²; p = 0.02) reduction but no improvements in body composition. Combined exercise interventions were the most effective in reducing BW (−5.50kg; p < 0.01) and body mass index (−1.86kg·m⁻²; p < 0.01). Interventions starting >6‐months after bariatric surgery were more successful in reducing BW (−5.02kg; p < 0.01) and body mass index (−1.62kg·m⁻²; p < 0.01). CONCLUSION: Exercise, combined exercise regimens and interventions starting >6‐months after bariatric surgery were effective in promoting BW, waist circumference and body mass index reduction. Exercise following bariatric surgery does not seem to favor body composition improvements.

    Abstract We aimed to assess if exercise applied after bariatric surgery (BS) improves bone mineral density (BMD) compared to usual care. Systematic search was conducted up to January 2021. Effect measures were determined using standardized mean difference (SMD) with 95% confidence interval (CI). Certainty evidence was assessed according to GRADE. Four clinical trials encompassing 340 patients were included. Exercise induced a positive BMD effect at total hip (SMD = 0.37 [95% CI 0.02, 0.71]; very low certainty evidence), femoral neck (SMD = 0.63 [95% CI 0.19, 1.06]; low certainty evidence), lumbar spine (SMD = 0.41 [95% CI 0.19, 0.62]; low certainty evidence), and 1/3 radius (SMD = 0.58 [95% CI 0.19, 0.97]; low certainty evidence). Exercise undertaken after BS seems to induce a positive effect on BMD.

    Abstract We aimed to determine the effects of different exercise types, duration, and onset after bariatric surgery (BS) on cardiometabolic risk factors (CMRFs). A systematic search was conducted up to July 2021. Eleven studies were identified (n = 618 participants). Overall, exercise induced reductions in systolic blood pressure (SBP; - 5.33 mmHg; 95%CI - 8.99, -1.66; p < 0.01). Combined exercises elicited reductions on SBP (- 7.18 mmHg; 95%CI - 12.42, - 1.94; p < 0.01) and triglycerides (- 17.56 mg/dL; 95%CI - 34.15, - 0.96; p = 0.04). SBP reductions were also observed on interventions starting > 6 months post-BS (- 7.71 mmHg; 95%CI - 13.12, - 2.31; p < 0.01), and on > 12-week protocols (- 5.78 mmHg; 95%CI - 9.91, - 1.66; p < 0.01). Overall exercise and particularly aerobic plus resistance protocols were an effective therapy to reduce CMRFs post-BS. Benefits were also observed with interventions starting > 6 months post-BS and with > 12-week duration. Trial registration: CRD42020161175 .

    Abstract This meta‐analysis aimed to assess the effect of Roux‐en‐Y gastric bypass (RYGB) on three‐dimensionally assessed volumetric bone mineral density (vBMD) with the effect of time on these changes, on bone quality, and the agreement of dual‐energy X‐ray absorptiometry (DXA) with quantitative computed tomography (QCT) or high‐resolution peripheral QCT (HR‐pQCT) estimates of bone loss. We searched PubMed, Web of Science, Cochrane, Scopus, and EBSCO. Longitudinal studies on adults undergoing RYGB in which vBMD was assessed by QCT or HR‐pQCT with ≥6 months follow‐up were included. Total hip (TH) changes were reported in four studies, lumbar spine (LS) in eight, radius in eight, and tibia in seven. Significant post‐RYGB vBMD reductions occurred at all skeletal sites analyzed. Meta‐regression revealed that time post‐RYGB was significantly associated with vBMD deterioration in all skeletal sites except at the TH. RYGB also led to significant deterioration on bone quality. DXA underestimated LS and overestimated TH bone losses post‐RYGB. In conclusion, RYGB was associated with significant vBMD loss, which makes screening of bone mass progression by three‐dimensional technology a crucial clinical issue to prevent fracture risk and osteoporosis.
