A research group has uncovered important details about how platelet-activating factor (PAF)—a powerful molecule involved in ...
Bodybuilding legend and former seven-time Mr. Olympia Phil Heath plowed through an intense upper body training session.
Protein and creatine supplements significantly aid muscle growth, each playing distinct roles. Creatine boosts energy production by increasing ATP, crucial for muscle contraction and recovery ...
Recordings of electrical activity from muscles allow us to identify the activity of pools of spinal motor neurons that send the neural drive for muscle activation. Decoding motor unit and motor neuron ...
As the muscle lengthens, the force of contraction is less but your muscles still provide force to control the movement, otherwise, you’d simply drop the weight.
Muscle twitches can occur for many reasons, such as a lack of sleep, caffeine use, nutrient deficiencies, overexertion, and stress. Depending on the cause, treatments and remedies may help relieve ...
In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult ...
"This new level of insight into the muscle receptor will help researchers understand how mutations in its gene cause disease, and may facilitate personalized treatment for individual patients with ...
“Being able to see the receptor details allows us to connect their differences to how one allows for nerve-muscle connection and the other allows for muscle contraction.” The findings of the study are ...
“Muscle fibers are composed of many components, such as various proteins, cell nuclei, organelles such as mitochondria, and molecular motors such as myosin that convert chemical fuel into motion and ...
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 ...
Previous research into how muscle works focused only on how it worked on a molecular level rather than how muscle fibers are shaped, that they are three-dimensional and are full of fluid.
