Real life problem.  You are a trainer and are called on to the field where a player is down with a severe cramp of his right hamstring (biceps femoris) muscle.  You know that cramps are caused by over-active motor nerve activity to the muscle.  Your associates want to stretch the cramping hamstring, but you say, “No!  I want the player to concentrate on contracting his right quadriceps muscles before we stretch.” 2. Why would contracting the opposing muscle rapidly improve the situation?

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.
