Abstract
In this study, digital tools are transversely used as research tools and training tools. The video analysis (from recording video sequences to tracking points in the frames and the statistical treatment of data) allowed us to elaborate a test to create a simulated disability of "dizziness". This test was reinvested in training course on Adapted Physical Activities and Health, and 37 students in their third year of studies at the University have been questioned (Condorcet's pairwise comparisons methodology) on the sensations they perceived after a judo throw, before and after a simulated disability of "dizziness". Results are manifold and suggest firstly that perceptions as "amplitude", "view", " body unit (body in one or more pieces)" appear modified and change their rank order, and others perceptions as "hearing" and "fear of pain" seem less important and remain in same and last place. On the other hand, the use of digital tools in the field of sportive practices shown that they are both: 1) accessible tools for research and tools usable in simple ways (scientific publications and implemented or analysis very close to real situations); 2) training tools (introduction of new course content).
