slow-twitch muscle fibers, which move more slowly but help to keep you moving longer fast-twitch muscle fibers, which help you move faster, but for shorter periods “Twitch” refers to the contraction, ...

All runners, according to a popular school of training thought, can be divided into two categories: slow-twitch and fast-twitch. Physiologically, this idea rests on pretty shaky ground. The old view ...

Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue. The findings offer a simpler, less time-consuming way for medical researchers to ...

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 ...

Fast-twitch fibers help with explosive movements like sprinting and weight lifting. Genetics and training influence the distribution of fast-twitch and slow-twitch muscle fibers. Doing strength ...

For decades, scientists believed that muscle fiber typology was mostly set at birth—some people were built for speed, others for endurance. However, a 2018 study led by Andrew Galpin of California ...

Titin was discovered four decades ago, but some physiology textbooks fail to recognize the important role it plays in muscle contraction. A series of rodent experiments showed that even with abundant ...

Engineers have found a simple and inexpensive new approach to creating bending artificial muscle fibers. Artificial muscles -- materials that contract and expand somewhat like muscle fibers do -- can ...

In the dynamic landscape of intelligent technology, electrically powered artificial muscle fibers (EAMFs) are emerging as a revolutionary power source for advanced robotics and wearable devices.
