The precise survey of underwater movements which undoubtedly represents the most important factor as regards propulsion, is one of the major difficulties in the analysis of the movements of swimming. In the biomechanical research which is founded on the use of cinematography, at standards as well as at high speed, television and photography, perhaps the most difficult problem is that of filming the movement at exactly the same speed with which the swimmer moves in the water. In order to solve this problem, we are presenting an apparatus developed in order to provide researchers with a movable platform which proceeds at the same speed as the swimmer and allows photographic recording of the swimmer, always maintaining the same shooting angle and therefore the most accurate analysis of the underwater movements.
