Supplementing a single protein found in the spinal cord could help prevent symptoms of Lou Gehrig's disease, according to a new study. Researchers found high levels of the protein -- called mitofusion ...

Biological muscles act as flexible actuators, generating force naturally and with an impressive range of motion. Unsurprisingly, scientists and engineers have been striving to build artificial muscles ...

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 ...

slow-twitch muscle fibers, which move more slowly but help to keep you moving longer fast-twitch muscle fibers, which help you move faster, but for shorter periods “Twitch” refers to the contraction, ...

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, ...

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 ...

Some researchers working on artificial muscles are seeing results even the fittest individuals would envy, designing muscles capable of lifting up to 12,600 times their own weight. The new muscles are ...
