The main premise of our research is that the specific force of speed runners, developed in direct relation to the speed of movement is the most important factor favoring / limiting the sports performance at the level of seniors. Starting force, impulse force, accelerating force are specific forms of manifestation of force in speed tests, both on the flat and on fences. The research has two components, one ascertaining, conducted on 68 subjects, the finalists C.M. of athletics and an experimental one, operationalized at the level of case studies, 9 subjects, speed runners, members of the Romanian Olympic team for J.O. London 2012. The aim of the research was to identify the importance of the speed-force relationship in the performance equation for the most valuable senior athletes who practice sprint tests and to experimentally test an instrument for objectifying the level of purity / explosive force parameters to determine their level and improve performance. through the ameliorative methodical intervention for increasing their value. The research conclusions validate the hypothesis and offer scientifically argued answers to the interrogative assertions formulated by us.
