A unique combination of medical and psychological competencies is needed to become a qualified sports psychologist in the United States, though individual qualifications and licensure requirements vary from state to state. Few schools in the U.S. offer undergraduate or graduate programs specifically in sports psychology, though students looking to major in this field may double-major in psychology and exercise science or pursue a degree in clinical psychology with a sports psychology concentration.
Graduate and post-graduate students typically complete advanced coursework in exercise science, kinesiology and clinical psychology. A one-year internship through a program approved by the American Psychological Association (APA) may be an additional requirement for graduation. Continuing education and training is available through several professional organizations, including the APA and the Association for Applied Sport Psychology, once state licensing or certification as a psychologist is obtained.
It appears that hypnosis, under other names, has been used since the beginning of time. In fact, it has been insinuated that the earliest description of hypnosis may be portrayed in the Old Testament and in the Talmud. There is also evidence of hypnosis in ancient Egypt, some 3,000 years ago. However, the man credited with the development of what has become modern hypnosis is Friedrich Anton Mesmer, an Austrian physician. One day, Mesmer watched a magician on a street in Paris demonstrate that he could have spectators do his bidding by touching them with magnets. Fascinated by the demonstration, Mesmer believed the magnets had power of their own and from this belief developed his theory of "animal magnetism." He also believed that good health depended on having correct magnetic flow and that the direction of one's magnetic flow could be reversed easily. He further believed that he could direct this magnetic flow into inanimate objects, that could then be used for the good health of others. The term "mesmerism" came to be applied to his mystical workings. He experienced much success in helping the people of Paris as well as visitors who came from other countries, upon hearing of his powers. Later he was completely discredited by a special commission of the French Academy appointed by the King of France, causing him to leave the country. Two of the more famous members of the French Academy at the time were chairman of the commission Benjamin Franklin, American ambassador to France, and Dr. Guillotine, the inventor of the execution device.
Griffith opened an athletic research laboratory at the University of Illinois in 1925. In 1925 he published an article, 'Psychology and Its Relation to Athletic Competition,' which is considered one of his most important works/writings. He also published a couple of textbooks, namely Psychology of Coaching and Psychology and Athletes. Griffith's progress was stunted when his lab was shut down in 1931 at the beginning of the Great Depression.
There are a number of ways to work with athletes but investing in a comprehensive education will allow for the greatest number of professional opportunities down the line. If you have a passion for helping people overcome obstacles and achieve success, it is worth investigating which training path will ensure you the highest level of competence that you can attain.
Hypnosis is not a dangerous procedure. It is not mind control or brainwashing. A therapist cannot make a person do something embarrassing or that the person doesn't want to do. The greatest risk, as discussed above, is that false memories can potentially be created and that it may be less effective than pursuing other, more established and traditional psychiatric treatments.

Modern hypnotherapy is widely accepted for the treatment of certain habit disorders, to control irrational fears,[35][36] as well as in the treatment of conditions such as insomnia[37] and addiction.[38] Hypnosis has also been used to enhance recovery from non-psychological conditions such as after surgical procedures,[39] in breast cancer care[40] and even with gastro-intestinal problems,[41] including IBS.[42][43]

With the above in mind, you should first understand that sports psychology is really an interdisciplinary science. Besides psychology, it is also concerned with disciplines such as biomechanics, physiology, and kinesiology. As a definition, the American Psychological Association’s Division 47 (Society of Sport, Exercise, and Performance Psychology) states the following:
This shows you the Therapeutic part of the session - the Suggestion Therapy section. The client I did the session for was an aspiring Author, so the session was created to enable her to bring these gifts and her message out into the world via a book. Note the suggestions given to the Subconscious mind as well as the Forward Pacing, Anchor & Post Hypnotic Suggestion.
Although this book is fascinating, without the guidance of a live instructor it cannot really be used as a practical learning tool. Although it seems there is almost nothing Dave Elman can't handle successfully with hypnosis, the reader may be left feeling a bit inadequate, as his physician students often did, when trying to duplicate his efforts. Obviously there is a lot to be said for intuitive skill in this area.
Experience is the best teacher. In the future, executive coaching will move from explaining to experiencing. People will desire to learn in a format that is memorable and fun. Breakthrough thinking and new information will be driven by executive individualization based on what experience the executive needs in order to achieve new patterns of action. - Ken Gosnell, CEO Experience
To get certified by the AASP, an individual must be a member of the organization, hold a graduate degree, demonstrate the requisite knowledge of the sports psychology field, and have several hundred hours of specific experience. Candidates with master’s degree are eligible for a provisional certification; a doctorate is required to obtain a standard certification.
David Lesser[21] (1928 - 2001) was the originator of what we today understand by the term Curative Hypnotherapy.[22] It was he who first saw the possibility of finding the causes of people’s symptoms by using a combination of hypnosis, IMR and a method of specific questioning that he began to explore. Rather than try to override the subconscious information as Janet had done, he realised the necessity- and developed the process- to correct the wrong information. Lesser’s understanding of the logicality and simplicity of the subconscious led to the creation of the methodical treatment used today and it is his innovative work and understanding that underpins the therapy and is why the term ‘Lesserian[23]’ was coined and trademarked. As the understanding of the workings of the subconscious continues to evolve, the application of the therapy continues to change. The three most influential changes have been in Specific Questioning (1992) to gain more accurate subconscious information; a subconscious cause/effect mapping system (SRBC)(1996) to streamline the process of curative hypnotherapy treatment; and the ‘LBR Criteria’ (2003) to be able to differentiate more easily between causal and trigger events and helping to target more accurately the erroneous data which requires reinterpretation.
