Power aspects of operated movement of the sportsman for a case of interaction with a apparatus showing elastic properties are examined. Research is executed on an example of the big turn back on a horizontal bar in sports gymnastics. In fullscale and computing experiments the opportunity of division of two systems is revealed: a apparatus and the locomotive system of the person. Their mutual influence against each other through power developed during movement is shown. At purposive movement of the sportsman applied models for movement concerning joints and concerning a sports apparatus differ in a kinematic part: in the first case power is determined on articulate angular speeds, in the second-on full angular speed of rotation of hands.
