The contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

Micro-organisms in the gut support healthy digestion by helping nerve cells within the intestine to regulate the contraction and relaxation of the muscle wall of the colon, according to new research ...

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.

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

New research into muscle contraction will give scientists a better understanding of bladder problems and pain during childbirth. Scientists have found that calcium, which allows muscle contraction to ...

Muscle co-contraction is a strategy used commonly in elderly people to increase their stability. Co-contraction involves the simultaneous contraction of pairs of muscles from opposing groups to lock a ...

Muscles are made to move. Stretching and contraction stimulate biochemical pathways within muscle that maintain tissue health. When movement slows—when a broken limb is immobilized in a cast, for ...

Objective: To determine if submaximal contractions used in contract-relax proprioceptive neuromuscular facilitation (CRPNF) stretching of the hamstrings yield comparable gains in hamstring flexibility ...

For most people, swallowing is second nature, but how does it occur, and why do some people have difficulty with it? Researchers at Kyushu University in Japan have started to tackle these questions by ...

Proprioceptive neuromuscular facilitation (PNF) is a form of assisted stretching. It combines passive stretching with muscle contraction. First, your partner applies force to stretch your muscle ...
