Bariatric surgery leads to loss of fat and fat-free mass (FFM). To preserve FFM it is recommended that weight loss interventions are accompanied by physical activity. However, it remains unknown if functional capacities spontaneously improve after a substantial weight loss. Study's aim was to assess the effect of bariatric surgery on strength, functional capacities and quality of life of participants with a body mass index (BMI) ≥ 35 kg/m.
Anthropometric parameters (weight, BMI, waist circumference), physical functions (quadriceps strength, walking capacity, spatio-temporal gait parameters, dynamic balance, lower limb power) and quality of life were assessed before and at three months after the bariatric surgery in 33 individuals who did not follow any physical activity program.
The anthropometric parameters, quality of life and three functional abilities (walking capacity, normal gait speed and lower limb power) improved significantly three months post-surgery. In contrast, fast gait speed, absolute strength, normalized strength, and dynamic balance did not improve.
A massive weight loss should be accompanied by an exercise program aiming to maintain FFM and to enhance muscle strength and balance. Such a program might also enhance functional capacities and help to sustain the weight loss over time.
减重手术会导致脂肪和去脂体重（FFM）的流失。为了保留 FFM，建议将减肥干预措施与身体活动相结合。然而，在大量体重减轻后，身体的功能能力是否会自动改善，目前仍不清楚。本研究的目的是评估减重手术后对 BMI≥35kg/m2的参与者的力量、功能能力和生活质量的影响。
在 33 名未参加任何身体活动计划的个体中，分别在减重手术前和手术后 3 个月评估了人体测量参数（体重、BMI、腰围）、身体功能（股四头肌力量、步行能力、时空步态参数、动态平衡、下肢力量）和生活质量。
术后 3 个月，人体测量参数、生活质量和 3 项功能能力（步行能力、正常步态速度和下肢力量）显著改善。相比之下，快速步态速度、绝对力量、归一化力量和动态平衡没有改善。
大量体重减轻应辅以锻炼计划，以保留 FFM 并增强肌肉力量和平衡。这样的计划还可能增强功能能力，并有助于随着时间的推移维持体重减轻。
