 | Eccentric movements are often defined as those exercise movements involving the lengthening of muscle fibers. |
 | Eccentric movements are involved in deceleration such as landing from a jump and parts of the movement of catching a ball such as a basketball. |

 | Eccentric is from the Greek for out of the centre, as opposed to concentric, in the centre. |
 | In astrodynamics, the eccentricity of an orbit can be calculated from orbital state vectors as an absolute value of eccentricity vector or using other methods based on orbital energy and angular momentum. |
 | In mechanical engineering, an eccentric is a wheel that rotates on an axle that is displaced from the focus of the circle described by the wheel —in other words, a mechanical motion that can operate either as a cam or a crank, depending upon how it is driven. |
