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, ...

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 ...

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 ...

Almost one in five people lack the protein α-actinin-3 in their muscle fiber. Researchers at Karolinska Institutet in Sweden now show that more of the skeletal muscle of these individuals comprises ...

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 ...
