Abstract
Efficient, stress and strain free movement with efficiency is an essential aspect of survival for living things. Therefore understanding normal movement and how the human organism accomplishes normal movement is vitally important for physicians to understand so they can determine what is normal and what is abnormal movement. In 1680, Giovanni Alfonso Borelli, discussed walking as vaulting over stiff legs using a pair of compasses and noted the importance of rebounding on compliant legs in running. Weight training has been around for centuries. It uses the force of gravity to oppose the force generated by muscle through concentric or eccentric contraction by using weights rather than elastic eccentric training to increase strength. Plyometric training, developed by Yuri Verkhoshansky, was a method of training brought to the US in 1971, involves quick, powerful movements involving pre-stretching the muscle & activating the stretch-shortening cycle to produce stronger concentric contraction.
