The U.S. economy is very close to falling into a damaging contraction — and many states are already experiencing a recession, according to Mark Zandi, chief economist at Moody’s Analytics. Zandi ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

As a doctor of physical therapy, I work with clients every day who are dealing with pain. The pain-medicine industry might tell you there are endless ways to reduce or eliminate pain without lifting a ...

No one can live without a heart pumping blood to the rest of the body. New research from the University of Missouri School of Medicine reveals more information about this vital function and how it's ...

The film discusses the intricate relationship between muscles and bones, highlighting the mechanics of body movement. It explains how muscles work by contracting and relaxing in coordination with ...

Time under contraction is not directly measured in a typical weight training program. Most people really don't even think about the number of seconds a given muscle is forced to work. Indirectly, ...

At one point or another, we’ve all experienced the unexpected, intense pain of a muscle cramp. Muscle cramps, also known as muscle spasms or charley horses, are the involuntary contraction of muscle ...

The sarcomere is the functional unit of striated muscle contraction. Previous studies have provided valuable information about the sarcomeric proteins and modulators that are necessary for activation ...

This study provides a valuable characterization of individual sarcomere's contractility and synchrony in spontaneously beating cardiomyocytes as a function of substrate stiffness. The authors, however ...

Muscle biophysics is in some measure already a mature science. The sliding-filament theory, originally presented in the 1950s, remains the bedrock of our understanding of sarcomere force generation.
