Human movement is reciprocal in nature: Opposing muscle groups must coordinate for proper movement. Muscle length and strength between opposing muscle groups need to be in balance for normal movement ...

Scientists discover that muscles repair themselves by moving thousands of internal nuclei, a rapid process that is key after ...

Eccentric exercise focuses on movements, or phases of a movement, that lengthen the muscles. Some examples of eccentric exercise include lowering into a squat or lowering into a press-up. In contrast, ...

A study in the Journal of Applied Physiology suggests quick bursts of moderate-intensity exercise can help your body use amino acids from your meals, which helps you build muscle. Researchers found ...

Medically reviewed by Katrina Carter, DPT Key Takeaways Voluntary muscles can be controlled by the person, like muscles in your neck and legs. Involuntary muscles work without you thinking about it, ...

The lunge is a popular, versatile exercise for strengthening the lower body. It works many muscles in one move and offers numerous benefits. Varying your technique emphasizes different muscles or ...

In a significant stride forward in the field of bio-inspired robotics, researchers have engineered artificial muscles powered by artificial intelligence (AI). These muscles, made from materials that ...

All animals move -- cheetahs faster, snails more slowly. Muscle contractions are the basis of movement in many, but not all, species. Some animal groups don't have any muscles at all, as they branched ...

Muscles and nerve fibers allow a person to move their body and enable the internal organs to function. There are more than 600 muscles in the human body. People also have different types of muscle. A ...

Neurobiologists from the University of Leicester have shown that insect limbs can move without muscles – a finding that may provide engineers with new ways to improve the control of robotic and ...
