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.

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 ...

Traditional lifting often fails as we age; discover the "continuous tension" method that firms skin and muscle without the ...

Myotonic dystrophy type 1 (DM1) is the most common form of adult-onset muscular dystrophy, affecting about 1 in 8,000 people. While it is well known for causing muscle weakness and stiffness, DM1 also ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

If your fitness goal is to up the ante on endurance, pack more power into your sprint, or supercharge your strength gains in the gym, it’s worth exploring – what are the different muscle fiber types?

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 ...
