Neuroscientists report that they can inhibit muscle contractions by shining light on spinal cord neurons. The researchers studied mice in which a light-sensitive protein that promotes neural activity ...

A new study out of Edith Cowan University in Perth, Australia, suggests that a few seconds of focused muscle training each day might be enough to increase strength — a surprising finding that could ...

All animals move -- cheetahs faster, snails more slowly. Muscle contractions are the basis of movement in many, but not all, species. Some animal groups don't have any muscles at all, as they branched ...

Isokinetic exercise is a type of strength training in which the speed of the movement remains constant, but the resistance varies. People tend to use specialized exercise machines to perform these ...
