slow-twitch muscle fibers, which move more slowly but help to keep you moving longer fast-twitch muscle fibers, which help you move faster, but for shorter periods “Twitch” refers to the contraction, ...

Skeletal muscle is one of the most abundant tissue types in the human body, but has proven difficult to produce in large quantities in the lab. Unlike other cell types, such as heart cells, neurons ...

Fast-twitch fibers help with explosive movements like sprinting and weight lifting. Genetics and training influence the distribution of fast-twitch and slow-twitch muscle fibers. Doing strength ...

Researchers building a model of muscle damage in a cultured system found that components leaking from broken muscle fibers activate ''satellite cells,'' which are muscle stem cells. While attempting ...
