Red and white fibers have been investigated in the diaphragm of white rats, normal and under effect of physical loadings, various in intensity and duration. Relative volume and amount of lipid inclusions and mitochondria and their profiles and amount of glycogen granules have been estimated per one unit of the fiber section area. In unadapted animals acute physical loadings result in exhaustion of the reserves in the areas with a high volumetric density of mitochondria. These changes are mostly pronounced in the red fibers. Under a prolonged effect of the physical loadings of the training regimen, muscle fibers of both types have similar ultrastructural changes, demonstrating certain increase in their oxidative potential.
对正常状态以及在不同强度和持续时间的体力负荷作用下的白鼠膈肌中的红肌纤维和白肌纤维进行了研究。已对每单位纤维截面积中的脂质包涵体、线粒体及其轮廓的相对体积和数量以及糖原颗粒的数量进行了估算。在未适应的动物中，急性体力负荷会导致线粒体体积密度高的区域储备耗尽。这些变化在红肌纤维中最为明显。在训练方案的体力负荷长期作用下，两种类型的肌纤维都有相似的超微结构变化，表明其氧化潜能有一定增加。
