A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object. This is the most ...

A new molecular pathway has been identified that is critical for maintaining the smooth muscle tone that allows the passage of materials through the digestive system. Researchers at UMass Medical ...

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.

One of the biggest things a first-time mother may wonder as she approaches her due date is what contractions will feel like during labor. Many women may even wonder if they will be able to recognize ...

At one point or another, we’ve all experienced the unexpected, intense pain of a muscle cramp. Muscle cramps, also known as muscle spasms or charley horses, are the involuntary contraction of muscle ...

Anyone who has had tight muscles or a muscle spasm knows how uncomfortable and limiting these experiences can be. But when you have spasticity, which causes tight muscles and uncontrollable ...

Time under tension (TUT) is a weightlifting technique designed to build muscle mass by increasing the time muscles spend activated during an exercise. We cover if it works and what its benefits are.

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 ...
