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.

Study in a Sentence: Researchers at Hesperos and the University of Central Florida have developed a first-of-its-kind, human-based model of sarcopenia, an age-related and inflammatory condition marked ...

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 ...

Muscular fatigue is associated with repeated muscle contraction exercises and with intense use of muscles with high intensity leading to a decline of performance and inability to continue with the ...

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.

The control of muscle contraction is usually described in terms of excitation–contraction coupling or muscle activation. Muscle relaxation has received much less attention, although its control is ...

Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system. MIT engineers have now found that exercise can also have benefits at the level of individual ...

This is a valuable study that develops a new model of the way muscle responds to perturbations, synthesizing models of how it responds to small and large perturbations, both of which are used to ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...
