Background Hamstring strain injury (HSI) burdens athletes due to high occurrence and recurrence rates. Previous surface EMG evidence suggests reduced voluntary activation (VA) may contribute to high ...

When you take a muscle through the full range of motion, it goes through three phases of muscle contraction: eccentric, isometric, and concentric. Placing more attention on one phase can yield ...

Eccentric Muscle Contraction: A type of muscle contraction in which, despite activation of motor units and the production of force, the external resistance forces the muscle to lengthen. This occurs ...

What do people mean when they talk about isometric, concentric and eccentric muscle contractions. My physio said something like this, and I was just curious. Very briefly, an isometric contraction ...

The origin is the end of a muscle which is attached to a fixed bone. The insertion is the other end of the muscle that is attached to the bone which moves. Muscular contractions are defined as the ...

Lifting weights for as little as three seconds a day can have a positive impact on muscle strength, a new study from Edith Cowan University (ECU) has discovered. A collaboration with researchers from ...

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 ...
