Fast-twitch fibers help with explosive movements like sprinting and weight lifting. Genetics and training influence the distribution of fast-twitch and slow-twitch muscle fibers. Doing strength ...

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 ...

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 ...

If your fitness goal is to up the ante on endurance, pack more power into your sprint, or supercharge your strength gains in the gym, it’s worth exploring – what are the different muscle fiber types?

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 ...

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 ...

Tsukuba, Japan—Muscle fibers, which constitute skeletal muscle, are classified into two main types: slow-twitch (Type I, red muscle) and fast-twitch (Type II, white muscle). Slow-twitch fibers are ...
