Coleman Griffith worked as an American professor of educational psychology at the University of Illinois where he first performed comprehensive research and applied sport psychology. He performed causal studies on vision and attention of basketball and soccer players, and was interested in their reaction times, muscular tension and relaxation, and mental awareness.[11] Griffith began his work in 1925 studying the psychology of sport at the University of Illinois funded by the Research in Athletics Laboratory.[12] Until the laboratory's closing in 1932, he conducted research and practiced sport psychology in the field. The laboratory was used for the study of sports psychology; where different factors that influence athletic performance and the physiological and psychological requirements of sport competitions were investigated. He then transmitted his findings to coaches, and helped advance the knowledge of psychology and physiology on sports performance. Griffith also published two major works during this time: The Psychology of Coaching (1926) and The Psychology of Athletics (1928). Coleman Griffith was also the first person to describe the job of sports psychologists and talk about the main tasks that they should be capable of carrying out. He mentioned this in his work “Psychology and its relation to athletic competition”, which was published in 1925.[13] One of the tasks was to teach the younger and unskilled coaches the psychological principles that were used by the more successful and experienced coaches. The other task was to adapt psychological knowledge to sport, and the last task was to use the scientific method and the laboratory for the purpose of discovering new facts and principles that can aid other professionals in the domain.
The birth of sports psychology in Europe happened largely in Germany. The first sports psychology laboratory was founded by Dr. Carl Diem in Berlin, in the early 1920s.[3] The early years of sport psychology were also highlighted by the formation of the Deutsche Hochschule für Leibesübungen (College of Physical Education)in berlin germany by Robert Werner Schulte in 1920. The lab measured physical abilities and aptitude in sport, and in 1921, Schulte published Body and Mind in Sport. In Russia, sport psychology experiments began as early as 1925 at institutes of physical culture in Moscow and Leningrad, and formal sport psychology departments were formed around 1930.[4] However, it was a bit later during the Cold War period (1946–1989) that numerous sport science programs were formed, due to the military competitiveness between the Soviet Union and the United States, and as a result of attempts to increase the Olympic medal numbers [5] The Americans felt that their sport performances were inadequate and very disappointing compared to the ones of the Soviets, so this led them to invest more in the methods that could ameliorate their athletes performance, and made them have a greater interest on the subject. The advancement of sports psychology was more deliberate in the Soviet Union and the Eastern countries, due to the creation of sports institutes where sports psychologists played an important role.

In today’s modern era of 24-hour meal delivery and extra-large food portions, many people are confused about how much and how often to eat. Gueron says one of the most common questions she gets is, “How late can I eat dinner and still lose weight?” Recently, several studies have shown that avoiding food past certain hours of the day or intermittent fasting can promote weight loss. She says a moderate approach that boosts weight loss and comes without apparent side effects for the healthy individual is the 12-hour intermittent fasting approach. An example is having your first morning meal no earlier than 7 a.m. and your last evening meal no later than 7 p.m. Thus, 12 hours without food or caloric beverages consumed gives your body time to rest from eating and promotes fat burning without unnecessary hunger that daytime fasting can cause.
Since hypnotherapy is an adjunct form of therapy, used along with other forms of psychological or medical treatment, there are many applications. Hypnotherapy can be used to treat anxiety, phobias, substance abuse including tobacco, sexual dysfunction, undesirable spontaneous behaviors, and bad habits. It can be used to help improve sleep, learning disorders, communication, and relationship issues. Hypnotherapy can aid in pain management and help resolve medical conditions such as digestive disorders, skin issues, and gastrointestinal side effects of pregnancy and chemotherapy. It can also be used by dentists to help patients control their fears or to treat teeth grinding and other oral conditions.
