Companion studies suggest muscle begins to decline decades before sarcopenia takes hold for keeps. The best part: The process ...

“Our findings highlight key molecular signatures and pathways in contracted muscle [...] that may contribute to skeletal muscle strength loss due to estrogen deficiency.” “Importantly, identification ...

The contractile responses of esophageal smooth muscle (SM) induced by platelet-activating factor (PAF) involve the activation of L-type voltage-dependent calcium channels (L-type VDCCs), ...

Glucocorticoid steroids improved muscle performance through distinct, sex-specific molecular mechanisms in mice, according to a Northwestern Medicine study published in the Journal of Clinical ...

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 ...

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.
