Hari Charan was another researcher that had a positive influence on sport psychology. In 1938, he began to study how different factors in sport psychology can affect athlete's motor skills. He also investigated how high altitudes can have an effect on exercise and performance, aeroembolism, and decompression sickness, and studies on kinesthetic perception, learning of motor skills, and neuromuscular reaction were carried out in his laboratory.[15] In 1964, he wrote a paper “Physical Education: An Academic Discipline”, that helped further advance sport psychology, and began to give it its scholarly and scientific shape. Additionally, he published over 120 articles, was a board member of various journals, and received many awards and acclaims for his contributions.

When therapists attempt to uncover so-called repressed memories, they may create false memories in their patients. In the 1980s and 1990s, the notion of uncovering repressed memories via hypnotherapy was very common. Because people are highly suggestible while they are under hypnosis, they may be more likely to “remember” things that did not actually occur, and then fervently believe them when they come out of the hypnotic trance.

As Martens argued for applied methods in sport psychology research, the increasing emergence of practitioners of sport psychology (including sport psychology consultants who taught sport psychology skills and principles to athletes and coaches, and clinical and counseling psychologists who provided counseling and therapy to athletes) brought into focus two key questions and a debate which continues to the present day: under what category does the discipline of sport psychology fall?, and who governs the accepted practices for sport psychology? Is sport psychology a branch of kinesiology or sport and exercise science (like exercise physiology and athletic training)? Is it a branch of psychology or counseling? Or is it an independent discipline?
Arousal regulation refers to entering into and maintaining an optimal level of cognitive and physiological activation in order to maximize performance. This may include relaxation if one becomes too anxious through methods such as progressive muscle relaxation, breathing exercises, and meditation, or the use of energizing techniques (e.g., listening to music, energizing cues) if one is not alert enough.[46] The use of meditation and specifically, mindfulness, is a growing practice in the field of arousal recognition. The Mindfulness-Acceptance-Commitment (MAC) Theory is the most common form of mindfulness in sport and was formed in 2001. The aim of MAC is to maximize human potential for a rich, full and meaningful life.[47] It includes specific protocol that involve meditation and acceptance practices on a regular basis as well as before and during competition. These protocol have been tested various times using NCAA men's and women's basketball players. In a study done by Frank L. Gardner, an NCAA women's basketball player increased her personal satisfaction in her performances from 2.4 out of 10 to 9.2 out of 10 after performing the specific MAC protocol for several weeks. Also, the effect of mental barriers on her game decreased from 8 out of 8 to 2.2 out of 8 during that same time period as a result of the MAC protocol.[48] Another study of the MAC protocol performed by Frank Gardner and Zella Moore on an adolescent competitive diver showed that when the MAC protocol is tailored to a specific population, it has the potential to provide performance enhancement. In this case, the vocabulary and examples in the protocol were tailored to be more practical for a 12-year-old. After performed the MAC protocol for several weeks, the diver showed between a 13 to 14 percent increase in his diving scores.[49] This finding is important because previously the majority of tests performed using the MAC protocol had been on world class athletes.
So we try to make athletes understand that there is a process to their sport, and that it is more important early on to get the process right than to worry about the result. Then, as the athletes get better and reach higher levels of competition, we put as much importance on the process as on the result. The hope is that the emphasis on the process will buffer the athlete from a bad loss. As long as they know that they performed to their best, they are more accepting of the result.
"I understand that thinking about talking to someone can be an anxiety provoking process - I will work with you to provide a nonjudgmental environment where we can safely discuss and explore your concerns, whatever they may be. I will help you better understand the connections between past experiences and your current difficulties, which I believe can ultimately lead to you having a more fulfilling life."
It is used for a wide variety of applications, and studies into its efficacy are often of poor quality[2] which makes it difficult to determine efficacy. Several recent meta-analyses and systematic reviews of the literature on various conditions have concluded that the efficacy of hypnotherapy is "not verified",[3] that there is no evidence[4][5] or insufficient evidence[6][7] for efficacy.
