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 ...

There is perhaps no better way to see the absolute pinnacle of human athletic abilities than by watching the Olympics. But at the Olympics – and at almost all professional sporting events – you rarely ...

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, ...

Proper hydration is far more than a basic health habit—it’s a powerful performance tool that supports strength, endurance, ...

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

There is perhaps no better way to see the absolute pinnacle of human athletic abilities than by watching the Olympics. But at the Winter Games this year — and at almost all professional sporting ...

Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system. MIT engineers have now found that exercise can also have benefits at the level of individual ...

Almost everyone shrinks with old age. Many older adults have more difficulty gaining muscle than they did in their childhood and teenage years. And when it comes to maintaining that muscle, the phrase ...

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 ...

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.
