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 ...

Scientists have performed the most in-depth analysis of fast and slow twitch muscle fibers and the different ways they respond to exercise. Their novel approach uses large scale protein analysis of ...

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 ...

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 ...

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 ...

Here’s why some muscle groups respond faster (or slower) to strength training—and what you can do about it.

Targeting the right muscle fibers is key.

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 has revealed a physiological function of ...
