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, ...

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 ...

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 ...

Biological muscles act as flexible actuators, generating force naturally and with an impressive range of motion. Unsurprisingly, scientists and engineers have been striving to build artificial muscles ...

A muscle fiber consists of just one cell, but many nuclei. A team has now shown just how varied these nuclei are. The study can help us better understand muscle diseases such as Duchenne muscular ...

Exercising regularly is one of the best defenses against metabolic diseases, such as obesity and diabetes—but why? It's a question that scientists are still struggling to answer. While exercising ...

Previous studies have shown that, in obesity, deposition of lipid droplets in skeletal muscles and changes of muscle fiber types can both contribute to insulin resistance. However, the relationship ...
