All runners, according to a popular school of training thought, can be divided into two categories: slow-twitch and fast-twitch. Physiologically, this idea rests on pretty shaky ground. The old view ...

Most cells typically have one nucleus that holds its genomic DNA. Muscle fibers, however, are large, individual cells that contain many nuclei. Reporting in Nature Communications, scientists have used ...

Researchers have identified the role of the large Maf transcription factor family in regulating fast twitch muscle fibers. A mouse model lacking Maf expression in the skeletal muscles exhibited a ...
