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.

Researchers developed a high-sensitivity proteomics method to analyze individual human muscle fibers. The technique identified 37 protein variations, including key contractile proteins and their ...

Together, these findings suggest that ferulic acid can act as a natural regulator of intestinal motility. By reducing excessive smooth muscle activity, the compound could potentially help calm ...

New research has shown one type of muscle contraction is most effective at increasing muscle strength and muscle size -- and rather than lifting weights, the emphasis should be on lowering them. Good ...

Time under contraction is not directly measured in a typical weight training program. Most people really don't even think about the number of seconds a given muscle is forced to work. Indirectly, ...

MICKLETON, N.J. (WPVI) -- Nearly everyone gets a muscle cramp from time to time. When muscle contractions won't stop and can't be controlled, that's called dystonia. A South Jersey man is now sharing ...

Learn why pickle juice is the athletes drink of choice for cramps, how it works, and whether it could also relieve menstrual cramps.

Though many people experience muscle twitching, it's often incorrectly identified as a muscle spasm. While both are involuntary contractions of a muscle, muscle spasms and muscle twitching aren't ...

Researchers have just made the unexpected discovery of a novel organization of muscle fibers in Parophidion vassali, a fish that lives in the Mediterranean Sea and, like many fish, uses specialized ...
