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 ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have discovered that a protein excreted by type I (slow) muscle fibers, key to muscle endurance, can cause surrounding myoblasts, ...

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 ...

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 ...

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 ...

If your fitness goal is to up the ante on endurance, pack more power into your sprint, or supercharge your strength gains in the gym, it’s worth exploring – what are the different muscle fiber types?

When you picture different athletes—marathon runners, gymnasts, and Olympic weightlifters, for example—you likely categorize them instinctively by their height, size, and build. But the differences in ...

Everyone is familiar, at least hand-wavingly, with the distinction between slow-twitch and fast-twitch muscle-fiber types. The former are great for running marathons; the latter are ideal for ...
