目的：机车综合征（LS）风险试验是近年来提倡的一种体能评价方法。生物电阻抗分析（BIA）测量的相位角是细胞健康和肌肉质量的指标。我们的目的是研究肌肉质量和相位角与LS风险阶段的关系。方法：对311例接受健康检查的患者进行前瞻性队列研究。所有参与者均进行了两步测试、站立测试和25题老年机车功能量表的LS风险测试。用BIA测定肌肉质量和相位角。对LS的三个风险阶段进行了比较研究。结果：在趋势检验中，随着LS危险阶段的进展，相位角明显减小，而肌肉质量无显著差异。在调整年龄和性别后，各LS危险阶段的相位角差异有统计学意义。肌肉质量在无风险和1期之间没有显著差异。结论：相对于肌肉质量，相位角更能反映LS风险，在LS风险后期明显减小。相位角可以作为LS风险的有效筛选工具。
Objectives: The locomotive syndrome (LS) risk test has recently been advocated for the evaluation of physical ability. Phase angle measurement by bioelectrical impedance analysis (BIA) is an indicator of cellular health and muscle mass. We aimed to investigate how muscle mass and phase angle are related to LS risk stage. Methods: A prospective cohort study was conducted in 311 patients who were undergoing a health checkup. All participants performed the two-step test, stand-up test, and 25-question geriatric locomotive function scale components of the LS risk test. Muscle mass and phase angle were measured using BIA. A comparison study was conducted among the three LS risk stages. Results: In the trend test, phase angle decreased significantly as the LS risk stage progressed, whereas muscle mass did not show a significant difference. After adjusting for age and sex, phase angle showed a significant difference among all LS risk stages. Muscle mass did not show a significant difference between no risk and stage 1. Conclusion: Compared to muscle mass, phase angle more strongly reflects LS risk and becomes significantly reduced at later LS risk stages. Phase angle can be a useful screening tool for LS risk.
