The body in movement and the production of images: from Marey’s chronophotographer to digital imagesImage fixing techniques’ history shows that recording instruments play a critical part. First came out all the photographic then video devices at the end of the XIXth century. Then, in the second half of the XXth century, came the video processes and digital imaging. These new techniques allowed to record what the human eye had not yet been able to observe (Demenÿ 1909). From then on, the techniques of visualization, by influencing our vision as they become more effective and more precise in the search for details often imperceptible to the bare eye, modified our relation to the body and more particularly to the body of a moving sportsman (Vigarello, 1986; Peter & Fouquet, 2010). A new map of the body is outlined and evolves with technological progress and innovations, multiplying the operating modes of movement control (Pozzo, 2000).
