Nebulin is a giant modular sarcomeric protein that has been proposed to play critical roles in myofibrillogenesis, thin filament length regulation, and muscle contraction. To investigate the ...

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, ...

Watching the elaborate motion of a pitcher throwing a baseball at more than 100 miles an hour illustrates the essential role of stretching prior to delivering large amounts of mechanical power.
