摘要:




文题释义:
羽状角:肌肉中肌纤维相对于肌腱或肌肉腹部的角度。羽状角的大小与肌肉的力量生成能力和收缩方式密切相关,一般认为羽状角与肌肉的收缩速度和做功效率有关,较大的羽状角表示肌肉在较短的时间内产生更快的肌肉收缩速度。
肌纤维长度/肌肉厚度比(Lf/Tm)指数:被定义为一种基于肌肉几何比例变化的指数,与传统的单一形态参数(如肌肉厚度或肌纤维束长度)相比,能更好地实现对肌肉萎缩的客观诊断,且研究者认为这个参数的使用不依赖于性别、体质量和身高等因素,可以成为一项更为通用且客观的衡量参数。

背景:高频超声技术的应用为老年人骨骼肌形态的精准评估提供了有效工具,但获取的骨骼肌形态参数与身体活动能力之间的关联性尚不明确。
目的:探究高频超声成像技术下老年女性腓肠肌形态学参数与身体活动能力的相关性,进而发现老年人身体活动能力的有效预测指标。
方法:于上海杉达学院周边社区招募年龄> 60周岁,具有独立活动能力的老年女性受试者59例,采集受试者腓肠肌高频超声图像,获取相关参数:包括肌肉厚度、肌纤维长度、羽状角和肌纤维长度/肌肉厚度(fiber length/muscle thickness,Lf/Tm)指数;并进行身体活动能力测试:包括10 m步行、计时起立行走、30 s坐站和握力的测试,对各形态参数和身体活动能力测试指标进行相关性分析。
结果与结论:①各骨骼肌形态参数间均存在显著相关性(P < 0.05);②羽状角与10 m步行测试结果呈负相关(r=-0.35,P < 0.05),与计时起立行走测试结果呈正相关(r=0.32,P < 0.05);③Lf/Tm指数与10 m步行测试、握力测试结果呈正相关(r=0.39,P < 0.01;r=0.30,P < 0.05),与计时起立行走测试结果呈负相关(r=-0.32,P < 0.05);④结果表明:腓肠肌羽状角和Lf/Tm指数与老年女性身体活动能力表现出了较好的相关性,可作为身体活动能力预测的有效指标。

Abstract: BACKGROUND: The application of high-frequency ultrasound technology provides an effective tool for the precise assessment of skeletal muscle morphology in the elderly. However, the correlation between the morphological parameters of skeletal muscle obtained and physical activity capacity remains unclear.
OBJECTIVE: To explore the correlation between morphological parameters of the gastrocnemius muscle and physical activity capacity in elderly females using high-frequency ultrasound imaging technology, thereby identifying effective predictive indicators for physical activity capacity in the elderly.
METHODS:
Fifty-nine elderly female subjects over the age of 60 with the ability to live independently were recruited in the communities surrounding Shanghai Sanda University. High-frequency ultrasound images of the subjects’ gastrocnemius muscles were collected to obtain the relevant parameters, including muscle thickness, fiber length, pennation angle, and fiber length/muscle thickness (Lf/Tm) index. Physical activity capacity tests were also conducted and relevant indicators included the 10-meter walk test, timed up-and-go test, 30-second chair stand test, and grip strength test. Correlation analyses were performed between various morphological parameters and physical activity capacity test indicators.
RESULTS AND CONCLUSION: Significant correlations were found between various muscle morphological parameters (P < 0.05). The pennation angle showed significant correlations with the 10-meter walking speed (r=-0.35, P < 0.05) and timed up-and-go test results (r=0.32, P < 0.05). The Lf/Tm index was positively correlated with 10-meter walking speed and grip strength test results (r=0.39, P < 0.01; r=0.30, P < 0.05), but was negatively correlated with timed up-and-go test results (r=-0.32, P < 0.05). All these findings indicate that the pennation angle and Lf/Tm index of the gastrocnemius muscle show a good correlation with physical activity capacity in elderly females, which can serve as effective predictive indicators for physical activity capacity.
