It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in ...

Researchers find that a gut bacterium may influence muscle strength and fitness, opening the door to probiotics that support ...

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, ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have discovered that a protein excreted by type I (slow) muscle fibers, key to muscle endurance, can cause surrounding myoblasts, ...

An international team of researchers has identified an intestinal bacterium that could play an important role in maintaining muscle strength, a discovery that could pave the way for the development of ...

University of Delaware’s Mona Batish is a molecular biologist. She studies circular RNAs formed as a result of so-called molecular mistakes that occur when a strand of RNA — the ribonucleic acid that ...

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 ...

Muscle knots are highly irritated muscle fibers that have tightened into a ball in one area of your muscle. These painful, tender spots can feel sore and often occur in your upper back, shoulders, or ...

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 ...
