The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a University of Michigan study. Nearly all animals use muscle to move, and it's been known for a long ...

Coordinating dozens of muscles typically requires complex neural control, and it is unclear how much of that coordination must come from the brain versus the body’s structure. Professor Mitra Hartmann ...

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 ...

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 ...

MIT scientists find that motor neuron growth increased significantly over 5 days in response to biochemical (left) and mechanical (right) signals related to exercise. The green ball represents cluster ...

Do you feel your muscles cramp, feel tired or experience irregular heartbeats after a long day? These signs indicate that electrolyte balance is off in your body. What are these electrolytes?
