Type IIb fast-twitch myofibers, known for their rapid contraction speed, are plentiful in small mammals but have largely diminished in humans. Researchers at the University of Tsukuba have discovered ...

Neuromuscular disorders can be caused by hereditary or acquired genetic mutations, impairing the function of skeletal muscles: those under voluntary control. These diseases cause muscles to weaken and ...

Researchers have discovered a mechanism in our cells that is essential to energy production in the muscles. The discovery may lead to new treatment for disorders affecting the muscles, like diabetes, ...

There are significant differences between, say, tearing a muscle in a sports injury versus muscle tissue wasting away from diseases like muscular dystrophy. Now, a new study led by experts at ...

Insulin resistance precedes and predicts the onset of type 2 diabetes mellitus (DM2), a chronic disease that causes high morbidity and mortality worldwide. In affected people, insulin is unable to ...

Tsukuba, Japan—Muscle fibers, which constitute skeletal muscle, are classified into two main types: slow-twitch (Type I, red muscle) and fast-twitch (Type II, white muscle). Slow-twitch fibers are ...
