Muscle growth is more than just moving heavy weights—it's a complex biological response. In this video, we explain how resistance training creates micro-tears in your muscle fibers, triggering a ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a University of Michigan study. Nearly all animals use muscle to move, and it's been known for a long ...

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 ...

In two new studies, North Carolina State University researchers have designed and tested a series of textile fibers that can change shape and generate force like a muscle. In the first study, ...

Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue. The findings offer a simpler, less time-consuming way for medical researchers to ...

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 ...

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 ...
