When you take a muscle through the full range of motion, it goes through three phases of muscle contraction: eccentric, isometric, and concentric. Placing more attention on one phase can yield ...

Companion studies suggest muscle begins to decline decades before sarcopenia takes hold for keeps. The best part: The process ...

For people with paralysis or amputation, neuroprosthetic systems that artificially stimulate muscle contraction with electrical current can help them regain limb function. However, despite many years ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

Dehydration may be one cause of muscle cramps, and some evidence suggests that electrolyte imbalances also contribute to them. Muscle cramps are painful, involuntary contractions of the muscles that ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...
