At the professional level, athletes look even for the smallest progress to increase their potential. Such is the case of sprinters were the difference of earning a gold or silver medal is about two tenths of a second, so "even the smallest improvement in performance is crucial," and here is were sports psychology steps in (Baum, 1999). Similarly, sports psychologist Johnson believes that "baseball is only 25 percent physical ... and that the difference between Triple A ballplayers and big leaguers is plain mental" (Rosellini, 1987). Certainly, mental training helps athletes deal with performance blocks; in other words, it helps them clear away obstacles that display themselves in different ways. For instance, many athletes make their mind up ahead and decide that they are not tough enough, that they lack the right genetic composition such as fast-twitch muscle fibers in the case of sprinters or slow-twitch muscle fibers for endurance runners or that they cannot tolerate a certain threshold of pain, and in such conditions this type of thinking limits their believe and ego (Lynch, 1994).
