The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a University of Michigan study. Nearly all animals use muscle to move, and it's been known for a long ...

Some workouts leave you buzzing, muscles pumping, and energy on high. Others leave you wondering if you made any progress at all. The difference often comes down to more than just the weight on the ...

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 ...

For most people, swallowing is second nature, but how does it occur, and why do some people have difficulty with it? Researchers at Kyushu University in Japan have started to tackle these questions by ...

Vibration plates trigger rapid muscle contractions, which may modestly improve muscle strength, recovery, and balance. Evidence for benefits like increased bone density or lymphatic drainage is ...

A kinesiologist shares six standing exercises that target underarm jiggle and rebuild tricep strength after 60.

Dystonia and chorea are two types of involuntary movement associated with neurological disorders. Dystonia movements are repetitive, while chorea movements are more random. A person with dystonia may ...

Engineers designed modular, spring-like devices to maximize the work of live muscle fibers so they can be harnessed to power biohybrid robots. Our muscles are nature's perfect actuators -- devices ...

Muscles waste as a result of not being exercised enough, as happens quickly with a broken limb that has been immobilized in a cast, and more slowly in people reaching an advanced age. Muscle atrophy, ...
