Skeletal muscle mechanics and force generation are governed by complex interactions between contractile proteins and passive structural elements. At the cellular level, the sarcomere – the fundamental ...

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.

When you take a muscle through the full range of motion, it goes through three phases of muscle contraction: eccentric, isometric, and concentric. Placing more attention on one phase can yield ...

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 research team affiliated with UNIST has unveiled a new type of artificial muscle that can seamlessly transition from soft ...

Though many people experience muscle twitching, it's often incorrectly identified as a muscle spasm. While both are involuntary contractions of a muscle, muscle spasms and muscle twitching aren't ...

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 ...
