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, ...

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

People often discuss the importance of removing, or “flushing out,” lactic acid from the blood after intense exercise to reduce muscle soreness, speed recovery, or boost athletic performance. After ...

Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

Large-conductance calcium-activated potassium (BK) channels are critical determinants of smooth muscle function by mediating rapid feedback between intracellular calcium levels and membrane potential.

The previous three articles in this series explored the form and function of muscle and, in particular, skeletal muscle. This article outlines how the contraction of muscles (outlined in part three of ...

Myosin is a key molecular motor in eukaryotes from the plant and animal kingdoms. Interactions between myosin motor domains and actin filaments are powered by the turnover of ATP to generate force and ...

Since the 1920s, scientists have associated the limits of endurance performance with the ability to transport and consume oxygen, most often focused on VO2 max. Despite how much attention is given to ...
