What Wikipedia says

Muscle contraction is the activation of tension-generating sites within muscle cells. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length (isometric contraction), such as when holding something heavy in the same position.
