背景与目的：小腿三头肌腓肠肌和比目鱼肌在功能和组织学上存在差异。因此，我们研究了这两种肌肉的肌肉厚度与年龄相关的变化，以及男性和女性之间这些变化的差异。研究对象为847名20 ~ 79岁的健康成年人。B型超声扫描仪，参与者坐在椅子上，被用来测量肌肉厚度从腓肠肌内侧肌肉的中点在最大周长的水平（目标点）。计算肌肉厚度与身高的比值。检查前验证超声测量肌肉厚度的评定者间和评定者内信度以及靶点的有效性。结果：与20多岁的同龄人相比，60岁或以上的女性和50岁或以上的男性的腓肠肌明显更薄。对于比目鱼肌，没有显着差异的厚度，发现在年龄组中的任何性别。从40岁到79岁，腓肠肌的肌肉厚度下降幅度大于比目鱼肌。结论：这些结果证实腓肠肌比比目鱼肌更早开始恶化，萎缩速度更快。仅在腓肠肌退化的发病年龄上存在显着的性别差异，男性比女性早。（Aging Clin Exp Res 2010; 22：24-30）（C）2010。埃迪特里斯·库尔蒂斯
Background and aims: Gastrocnemius and soleus in the triceps surae have functional and histological differences. We therefore investigated age-related changes in muscle thickness of these two muscles, as well as the difference in these changes between men and women. Methods: Participants comprised 847 healthy adults aged 20 to 79 years. A B-mode ultrasound scanner, with participants sitting on a chair, was used to measure muscle thickness from the midpoint of the gastrocnemius medialis muscle at the level of maximum girth (target point). The ratio of muscle thickness to height was calculated. The inter-rater and intra-rater reliability of measuring muscle thickness with the ultrasound scanner and the validity of the target point were demonstrated before the examination. Results: Gastrocnemius was significantly thinner in women aged 60 or older and in men aged 50 or older, compared with their counterparts in their 20s. For soleus, no significant differences in thickness were found among the age groups in either sex. Decline in muscle thickness from age 40-79 was greater for gastrocnemius than for soleus. Conclusions: These results confirm that gastrocnemius starts to deteriorate earlier and atrophies at a faster pace than soleus. A significant sex difference was found only in the onset age of gastrocnemius deterioration, which was earlier in men than in women. (Aging Clin Exp Res 2010; 22: 24-30) (C) 2010. Editrice Kurtis
