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 ...

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 ...

Many people start strength training because they want to build muscle. That’s a great goal – building muscle can help you look and feel great. It improves your metabolism, self-esteem, and overall ...

Scientists discover that muscles repair themselves by moving thousands of internal nuclei, a rapid process that is key after ...

Scientists have discovered a sweet spot in animals that explains why fast moving animals like the cheetah can reach such high speeds. Animals that can run fast, such as the cheetah, tend to be medium ...

This article is part of a broad series on recent advances in the science and medicine of longevity and aging. The series covers a range of topics, including musculoskeletal health. Expect more ...

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 ...

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 ...

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 ...

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 ...

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 ...

Hierarchical structure of muscle and activation of thin filaments. In both skeletal and cardiac muscles under a relaxed state, a low intracellular calcium ion concentration is maintained and the ...
