One of the simplest concepts of sports psychology is developing positive self talk. It's also one of the hardest sports psychology skills to master. Research supports the theory that an athlete who continually practices positive self talk will improve his or her sports performance. Succumbing to negative mental self talk is a sure way to reduce performance and sports success. Over time and with repetition an athlete can develop a new habit of thinking positive statements and thoughts and expect a more positive outcome. It's this connection between the words and the belief that is the ultimate goal of this technique. Another important factor of positive self talk is that it must be possible and believable.
