Effects of long duration hypergravity on m. soleus morphology characteristics are still unknown. Particularly, only one paper describes the size and myosin heavy chain profiles of rat hindlimb extensor muscle fibers after 2 weeks of +2 G exposure. Earlier it was shown that long term overloading induced changes in skeletal muscle fiber cross-sectional area (CSA), fiber composition, and imitochondrial content. The aim of our study was to evaluate quantitatively structural parameters of m. soleus contractile apparatus after 19 day exposure to +2 G overloading.
长时间超重对比目鱼肌形态特征的影响仍不清楚。特别是，只有一篇论文描述了大鼠后肢伸肌纤维在 +2G 暴露 2 周后的大小和肌球蛋白重链分布情况。早期研究表明，长期过载会导致骨骼肌纤维横截面积（CSA）、纤维组成和线粒体含量发生变化。我们研究的目的是定量评估比目鱼肌收缩装置在 +2G 过载暴露 19 天后的结构参数。
