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 ...

A team of researchers has developed a simple lab-based system for growing human muscle cells that are capable of vigorously contracting. A team of researchers at Tohoku University have developed a ...

As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death.

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.
