concentric

concentric
a) Having a common center.

Antonym: eccentric. Concentric and eccentric movements are collectively referred to as isotonic (with motion), the antonym of which is isometric (without motion).

b) (of a motion) in the direction of contraction of a muscle. (E.g. extension of the lower arm via the elbow joint while contracting the triceps and other elbow extensor muscles; closing of the jaw while flexing the masseter).
