Your skeletal muscles are made up of bunches of elongated, rod-shaped cells called muscle fibres. Each of your muscle cells is packed full of thinner fibres called myofibrils. These fibres contain ...

A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object. This is the most ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

Atomic images of muscle molecules in action have now been captured by researchers, giving possibility of new nanomachines. At the molecular level, muscle contraction is defined by myosin molecules ...

Beet juice boosts endurance for many (but not all) people, according to a series of studies over the past five years or so. The active ingredient appears to be nitrate, which somehow reduces the ...

The muscular system works to control the movement of our body and internal organs. Muscle tissue contains something called muscle fibers. Muscle fibers consist of a single muscle cell. They help to ...
