More mileage during training results in faster finish times, right? Recent research suggests that might be true for some runners—but not for everyone. Before and immediately after each training period ...

Scientists have performed the most in-depth analysis of fast and slow twitch muscle fibers and the different ways they respond to exercise. Their novel approach uses large scale protein analysis of ...

Most fitness-minded people have probably heard of fast- and slow-twitch muscle fibers. However, the distinction can be somewhat mysterious, especially in the context of understanding how it relates to ...

A muscle fiber consists of just one cell, but many nuclei. A team has now shown just how varied these nuclei are. The study can help us better understand muscle diseases such as Duchenne muscular ...

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 ...

For example, the researchers observed that the regenerating muscle contained more active genes responsible for triggering muscle growth. "What really astonished us, however, was the fact that, in both ...

Most cells typically have one nucleus that holds its genomic DNA. Muscle fibers, however, are large, individual cells that contain many nuclei. Reporting in Nature Communications, scientists have used ...

Add Yahoo as a preferred source to see more of our stories on Google. in the foreground, we see a woman wearing atheletic clothing and smiling as she lifts a dumbell off the ground while holding a ...

A research team led by Prof. CHEN Yan and Prof. YANG Lifeng from the Shanghai Institute of Nutrition and Health of the Chinese Academy of Sciences has revealed a physiological function of ...

A muscle fiber consists of just one cell, but many nuclei. A team at the MDC led by Professor Carmen Birchmeier has now shown just how varied these nuclei are. The study, which has been published in ...
