背景在严重肥胖的个体中，通过减肥手术诱导的体重减轻能够促进合并症的减少并改善呼吸道症状。然而，由峰值摄氧量（VO 2 peak）反映的心肺适应性（CRF）在术后保持久坐的个体中可能不会改善。本研究的目的是评估体育锻炼计划对肥胖女性减肥手术后CRF和肺功能的影响，并将其与对照组进行比较。心肺运动试验（CPX）在3 MPO期，将患者分为对照组（CG，n= 6）和干预组（IG，n= 6）。CG只收到一般的指导方针，而IG进行了结构化和监督的体能训练计划，涉及有氧运动和阻力exercises，持续12 weeks.ResultsAll患者有显着减少人体测量和增加手术后的肺功能，组间无差异。然而，只有IG表现出显著增长，VO 2峰值和总CPX持续时间为5.9 mL/kg/min（p< 0.05）（23.8%）和4.9分钟（42.9%），分别。Conclusionsapplying体育锻炼计划，一组肥胖妇女减肥手术后3个月，可以促进显着增加CRF只有在训练组，而且还显示单独的减肥手术引起两组患者肺功能的改善。
BackgroundIn severely obese individuals, reducing body weight induced by bariatric surgery is able to promote a reduction in comorbidities and improve respiratory symptoms. However, cardiorespiratory fitness (CRF) reflected by peak oxygen uptake (VO2peak) may not improve in individuals who remain sedentary post-surgery. The objective of this study was to evaluate the effects of a physical training program on CRF and pulmonary function in obese women after bariatric surgery, and to compare them to a control group.MethodsTwelve obese female candidates for bariatric surgery were evaluated in the preoperative, 3 months postoperative (3MPO), and 6 months postoperative (6MPO) periods through anthropometry, spirometry, and cardiopulmonary exercise testing (CPX). In the 3MPO period, patients were divided into control group (CG,n= 6) and intervention group (IG,n= 6). CG received only general guidelines while IG underwent a structured and supervised physical training program involving aerobic and resistance exercises, lasting 12 weeks.ResultsAll patients had a significant reduction in anthropometric measurements and an increase in lung function after surgery, with no difference between groups. However, only IG presented a significant increase (p< 0.05) in VO2peakand total CPX duration of 5.9 mL/kg/min (23.8%) and 4.9 min (42.9%), respectively.ConclusionsApplying a physical training program to a group of obese women after 3 months of bariatric surgery could promote a significant increase in CRF only in the trained group, yet also showing that bariatric surgery alone caused an improvement in the lung function of both groups.
