Learn more about the different types of muscle contractions, how to do them, what they’re used for, and the benefits.

Find out about the structure of your muscles and how they contract and relax.

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study.

By studying sarcomeres, the basic unit controlling changes in muscle length, scientists proposed the sliding filament theory to explain the molecular mechanisms behind muscle contraction.

The arrangement of muscles and tendons has been studied in detail by anatomists, surgeons and biomechanists for over a century, and the energetics and mechanics of muscle contraction for almost as ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

Those who performed eccentric contractions showed the most substantial gains in strength — improvements ranged between 10 and 13 percent across all measured types of muscle contraction.

Researchers at UT Southwestern Medical Center have uncovered the detailed shape of a key protein involved in muscle contraction. The report, published today in Neuron, may lead to improved ...
