Investigators report that they have been able to drive cells to grow into muscle fibers, producing millimeter-long muscle fibers capable of contracting in a dish and multiplying in large numbers. This ...

A new 3D model shows that Duchenne gene therapy can repair muscle fibers but fails to shut down the signals that drive scarring.

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 ...

Engineers at Washington University in St. Louis have developed a new class of protein-based fibers modeled on the aligned structure of animal skeletal muscle, producing materials that resist ...

A specific gut bacterium found in human stool samples is linked to significantly stronger muscles in both young and older adults, according to a peer-reviewed study published in the journal Gut. Older ...

Researchers discovered that R. inulinivorans plays an important role in muscle strength and could act as a probiotic candidate for nutraceutical interventions targeting age-related muscle-wasting ...

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 fitness-minded people have probably heard of fast- and slow-twitch muscle fibers. However, the distinction can be somewhat mysterious, especially in the context of understanding how it relates to ...

Different types of exercise encourage the formation of different types of muscle fibers, or the cells that make up your muscles. Slow twitch muscle fibers support endurance activities like ...
