The ABCs of Muscle Contraction

Skeletal muscles can produce power different ways. In general, muscles can shorten, lengthen and be relatively static while generating force.

A: Active shortening – such as what commonly takes place when lifting a Robbins Pathology textbook off the desk using your biceps – is referred to as concentric contraction. It occurs when a muscle does not need to reach its maximum level of power, and its starting point is often from rest.

B: Active lengthening. When an active muscle requires more power, it may do so while lengthening. If you want to put that Robbins textbook down slowly – so as not to damage your desk – your biceps accomplish this as they’re lengthening. This is referred to as eccentric contraction. The quadriceps function the same during a walk or run following foot strike (of the heel if walking, or mid-foot if running). While eccentric activities are the best way to train a muscle for increased strength, most injuries also occur in this contractile state (especially in the anaerobic fibers).

C: If you’re holding Robbins’ textbook while reading it, you’re generating and maintaining muscle force equal to that of gravity. This is called isometric contraction, where the muscles are neither lengthening nor shortening.
