A mouse model lacking Maf expression in the skeletal muscles exhibited a significant loss of type IIb myofibers, a subtype of fast twitch fibers. Overexpression of large Mafs promoted type IIb ...

Skeletal muscle fibers twitch to create short bursts of energy. Many muscle fibers contract quickly for fast movements, while others move slowly, like the muscles in your back that maintain posture.

International Journal of Obesity - Fiber type dependent upregulation of human skeletal muscle UCP2 and UCP3 mRNA expression by high-fat diet Skip to main content Thank you for visiting nature.com.

Furthermore, on looking at fibers taken from calf muscles, they found Msi2 was most strongly expressed in type 1 or “slow” fibers, fibers with more endurance but less explosive power than ...

Myopathies are a class of diseases that attack your skeletal muscles. These diseases make your muscles weak by targeting the muscle fibers. Myopathies can be inherited or acquired, and they often ...

When you sprint, the "fast" muscle fibers give you that winning kick. In a marathon or just day-to-day activity, however, the "slow," or type 1 fibers, keep you going for hours.

Skeletal muscle tissue is made up of hundreds of thousands of fibers which contract on command. However, they are not all the same. There are “slow” type I muscle fibers, ...

A protein family’s role in the regulation of fast-twitch muscle fibers – those involved in fast and powerful movements – has been identified by scientists at the University of Tsukuba. The research is ...
