In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type ...

From the first nerve signal to the final movement, your muscles rely on a complex chain of events involving nerves, proteins, and energy. Actin and myosin filaments slide past each other to create ...

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

A Johns Hopkins-led study reports that severe obesity in people with heart failure with preserved ejection fraction (HFpEF) is linked to weakened contraction of heart muscle cells, but this defect may ...

Cytokinetics Inc. has identified bicyclic piperazinones with the ability to modulate skeletal muscle contractility reported to be useful for the treatment of amyotrophic lateral sclerosis, spinal ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

Time under contraction is not directly measured in a typical weight training program. Most people really don't even think about the number of seconds a given muscle is forced to work. Indirectly, ...
