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.

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 ...

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, ...

The sarcoplasmic reticulum (SR) is a specialised organelle in skeletal muscle fibres that plays a pivotal role in regulating calcium dynamics crucial for muscle contraction and relaxation. Acting as ...

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 ...

New research has shown one type of muscle contraction is most effective at increasing muscle strength and muscle size -- and rather than lifting weights, the emphasis should be on lowering them. Good ...

Good news for those who struggle to fit a gym workout into their day: you may be able to cut your weights routine in half and still see the same results. New research from Edith Cowan University (ECU) ...
