  • Types of Muscle Contraction During Running | Livestrong

    When this contraction results in shortening of the muscle, as in the lifting motion of a biceps curl, it is called a concentric contraction Contraction that occurs as your muscle lengthens under stress, for example, lowering the weight in a biceps curl, is referred to as an eccentric contraction

  • Eccentric (mechanism) - Wikipedia

    In mechanical engineering, an eccentric is a circular disk (eccentric sheave) solidly fixed to a rotating axle with its centre offset from that of the axle (hence the word "eccentric", out of the centre) It is used most often in steam engines, and used to convert rotary into linear reciprocating motion to drive a sliding valve or pump ram
