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 ...

Type IIb fast-twitch myofibers, known for their rapid contraction speed, are plentiful in small mammals but have largely diminished in humans. Researchers at the University of Tsukuba have discovered ...

Muscle loss in midlife isn't just about weaker fibers—it's a breakdown in how your brain talks to your body. Here is how to retrain your nervous system for lasting power.

Here's how muscle growth, or hypertrophy, works and four ways to optimize hypertrophy including nutrition and resistance ...

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 ...

Tsukuba, Japan—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 ...
