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 ...

Your body’s muscle fibers aren’t all the same—and they don’t adapt to training in the same way. Understanding the difference between slow-twitch and fast-twitch fibers can help you tailor workouts for ...

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 ...

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 ...

Usain Bolt, the world’s fastest person, ran a 100-meter sprint at a speed of 23.35 miles per hour (37.57 kilometers per hour). That’s mind-blowingly fast for a human. It’s about the same speed as ...

Researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke (DIfE) and other partner institutions of the German Center for Diabetes Research (DZD) have now identified a previously ...

Targeting the right muscle fibers is key.

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 ...
