背景:肌肉减少症是一种与年龄相关的肌肉质量和力量的进行性丧失,可以通过阻力训练进行调节。本研究旨在探讨TRX悬吊训练(TST)对老年男性肌少症患者血清神经肌肉、生长因子及功能指标的影响。一种与年龄有关的疾病,其特征是进行性肌肉质量和力量丧失。
方法:将19例老年男性(年龄=74.87±4.58岁)随机分为两组,TST组(n=10)和对照组(n=9)。调节肌肉标志物的血清浓度,人体测量和身体成分指数,和功能测试在基线和8周后进行评估。训练方案包括八周的TRX练习,每周三次。
结果:经过8周的训练,生长因子如卵泡抑素(FST)(P=0.001),22kDaC末端聚集蛋白片段(CAF)(P=0.031),与对照组相比,训练组中生长分化因子15(GDF15)(P=0.049)显着增加,肌肉生长抑制素(MSTN)(P=0.002)显着降低。然而,ASMM/m2无显著性差异(P=0.527),SMM/m2(P=0.621),组内或组间的体脂质量(P=0.433)。此外,TRX悬吊训练对功能测试和改善步态速度有显著影响(P=0.037),椅架(P=0.016),和TUG(P=0.016)以及握力(P=0.035)。
结论:我们的研究结果强调了TRX悬吊训练在提高老年肌肉减少症患者血清肌肉生长因子水平和功能能力方面的有效性。因此,考虑到正在进行的COVID-19大流行,该方案可以证明对这一人口群体有益.

BACKGROUND: Sarcopenia is an age-related progressive loss of muscle mass and strength that can be modulated by resistance training. This study aimed to investigate the effects of TRX Suspension Training (TST) on serum levels of neuromuscular and growth factors and functional indices in elderly men with sarcopenia, an age-related condition characterized by progressive muscle mass and strength loss.
METHODS: Nineteen sarcopenic elderly men (age = 74.87 ± 4.58 years) were randomly assigned into two groups, the TST group (n = 10) and the control group (n = 9). Serum concentrations of regulatory muscle markers, anthropometric and body composition indices, and functional tests were evaluated at baseline and after 8 weeks. The training protocol consisted of eight weeks of TRX exercises, with three weekly sessions.
RESULTS: After 8 weeks of training, growth factors such as Follistatin (FST) (P = 0.001), 22 kDa C-terminal agrin fragment (CAF) (P = 0.031), and growth differentiation factor 15 (GDF15) (P = 0.049) increased significantly in the training group in comparison to the control group and Myostatin (MSTN) (P = 0.002) had a significant decrease. However, there was no significant difference in ASMM/m2 (P = 0.527), SMM/m2 (P = 0.621), or Body fat mass (P = 0.433) within or between groups. In addition, the TRX Suspension Training had a significant effect on the functional tests and improved gait speed (P = 0.037), chair stand (P = 0.016), and TUG (P = 0.016) as well as Handgrip strength (P = 0.035).
CONCLUSIONS: Our findings highlight the efficacy of TRX Suspension Training in enhancing the serum levels of muscle growth factors and functional capacities among elderly individuals with sarcopenia. Therefore, considering the ongoing COVID-19 pandemic, this protocol can prove beneficial for this demographic group.
