Investigators report that they have been able to drive cells to grow into muscle fibers, producing millimeter-long muscle fibers capable of contracting in a dish and multiplying in large numbers. This ...

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 ...

Scientists at the University of Minnesota have succeeded in almost completely regenerating skeletal muscle in a mouse model of muscular dystrophy, using genetically unmodified mouse pluripotent stem ...

A single species of gut bacterium, one that thrives on the fiber-rich foods central to the Mediterranean diet, boosted ...

All runners, according to a popular school of training thought, can be divided into two categories: slow-twitch and fast-twitch. Physiologically, this idea rests on pretty shaky ground. The old view ...

As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death.

There are a bunch of different reasons that serious endurance athletes generally don’t have big pipes. The most obvious one is that they spend a lot of time running and pedaling and so on, and very ...

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 ...

Skeletal muscle is one of the most abundant tissue types in the human body, but has proven difficult to produce in large quantities in the lab. Unlike other cell types, such as heart cells, neurons ...
