Their findings, published in the journal Nature Physics, reveal that the speed of muscle contraction is limited not just by how quickly the molecular motors can work, but also by how fast fluid can ...

U-M physicist Suraj Shankar and Harvard’s L. Mahadevan developed a theoretical model showing that fluid movement through muscle fibers dictates contraction speed. They discovered a new type of ...

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

The work opposes this stem cell-centric view, demonstrating that muscle integrity is also maintained through an alternative myofibre autonomous repair mechanism.

What are the different types of muscle fiber contraction? Gregory Grosicki, Associate Professor of Kinesiology and director of Georgia Southern University Exercise Physiology Laboratory, says that ...

However, from this molecular mechanism we can determine thermodynamic mechanisms of muscle contraction. While it may seem odd from a 17th century rational mechanics perspective, the physiological ...

This muscle fiber self-repair process occurs rapidly both in mice and in humans after exercise-induced muscle injury, and thus represents a time- and energy-efficient protective mechanism for the ...

Researchers describe a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fibre nuclei, and independently of muscle stem cells.
