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 ...

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release. The ...

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 ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

Space exploration activity has been increasing. In turn, researchers are more interested than ever in uncovering more about how space travel affects human health and the progression of disease.

A groundbreaking new study has shown how you can increase muscle growth while spending half the amount of time in the gym. The study, authored by Edith Cowan University professor Ken Nosaka, found ...
