A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object. This is the most ...

Isotonic contractions – these occur when a muscle contracts and changes length and there are two types: Isotonic concentric contraction – this involves the muscle shortening. The origin and insertion ...

The term ‘lifting’ may dominate when we talk about building strength in the gym – but could bringing weights back down actually be what’s best for you? New research from Edith Cowan University found a ...

New research has shown one type of muscle contraction is most effective at increasing muscle strength and muscle size -- and rather than lifting weights, the emphasis should be on lowering them. Good ...

Isometric exercises are exercises that involve the contraction of muscles without any movement in the surrounding joints. Most muscle strengthening exercises involve moving the joints, using the ...

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

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 ...
