The article is based on a study the object of which is to see how the high-level sportsmen in disability sport manage their mental capacities in competitive phase and if golf and tennis practice influence these mental capacities. At the high-level, it is not the technical gesture the main factor but the mental capacity, that is, make good choice (concentration), regulate the thoughts, manage the stress and anxiety and to remain persevering (motivation). Thirty people with motor disabilities participated in this study and answered a questionnaire concerning the psychological factors built from validated tools, before, during and after the competition. For all the followers, the self-confidence is important (that is 17 people/30) and the capacity to surpass itself is essential (22/30). Nevertheless, the sportsmen say themselves little inclined "to feel belligerent in difficult situation" (10/30) And "to check his feelings" (6/30). The anxiety is a factor little influencing before, during and after the competition, the averages remain low. Whereas for the stress, the sportsmen are more put under stress during the competition in particular for the tennis players. By dealing with the concentration, we can see that the scores are not very high, what could explain this light vulnerability in front of agents stressors (the competitive phase). The players in sport for people with disabilities trust them moderated what is an asset to manage better its stress. He would be interesting to work with them, the awareness of the made progress and to make (6 people concerned only by this item), with a contract training-competition and a specific work on the capacity mental as the internal speech and the fixation of objectives to manage better the stress.
