This study examined the benefits of an 11-months multicomponent exercise program (MEP) on muscular strength (MS) after bariatric surgery.
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.
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).
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.

本研究旨在探讨为期 11 个月的多组分运动方案（MEP）对减重手术后肌肉力量（MS）的益处。
在 84 名随机患者中，有 41 名来自运动组（EG）和 20 名来自对照组（CG）的参与者纳入分析。EG 在减重手术后 1 个月（BS）开始接受监督 MEP，同时接受标准医疗护理，而 CG 仅接受医疗护理建议。术前、术后 1、6 和 12 个月通过等速动力学评估膝关节和躯干 MS，通过双能 X 射线吸收法评估身体成分。
MEP 对术后 6 和 12 个月时膝关节和躯干区域的绝对 MS 没有显著影响。然而，相对 MS 显示出显著的改善。术后 6 个月时，膝关节屈曲在 60°/s 时相对于体重（BW）显著增加（p=0.047），膝关节伸展在 180°/s 时相对于 BW 也显著增加（p=0.009），膝关节伸展在 60°/s 时相对于总瘦体重（p=0.040）也显著增加。术后 12 个月时，膝关节屈曲在 60°/s 时相对于 BW 也显著改善（p=0.038）。
虽然 MEP 对绝对 MS 没有显著改善，但本研究发现相对 MS 显著增强，特别是在 MEP 参与后主要膝关节屈曲。进一步的研究应该探索不同的运动强度和频率，以优化术后 MS 在 BS 后的恢复。
