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 ...

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 ...

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 ...

If you’ve ever wondered why some people seem to adapt more quickly to resistance training, it’s probably due to the type of skeletal muscle tissue they have. Each of our muscle fibers is either ...

A research team led by Prof. Chen Yan and Prof. Yang Lifeng from the Shanghai Institute of Nutrition and Health of the Chinese Academy of Sciences revealed a physiological function of monocarboxylate ...

Researchers developed a high-sensitivity proteomics method to analyze individual human muscle fibers. The technique ...

Most humans move a lot less than our ancestors did, a change in use which is likely reflected in the composition of muscles themselves. Understanding our muscle makeup is a key step towards improving ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have shown that the protein Musashi-2 (Msi2) plays a key role in the regulation of mass and metabolic processes in skeletal muscle. They ...

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 ...
