While most muscles in mammals contain a mixture of slow- and fast-twitch fiber types, some muscle beds are enriched for one type or the other, Spiegelman said.
Spiegelman说，大部分哺乳动物的肌肉包含两种类型的肌纤维，但有些肌肉是偏重于富含其中的一种。
Your distance runs, of course, produce aerobic gains, including increased blood volume and capillarization, enhanced mitochondrial density and size, and improved slow-twitch fiber development.
你的耐力训练可以提高你的有氧能力，包括增加血液量和斜阳能力，提高线粒体的密度和体积，促进慢肌纤维的发育。
