Sports psychology began with research on sports performance with psychologist and researchers Norman Triplett (cyclists are speedier in competition than when they ride solo) and Walter Miles (studied reaction time of football players to increase their reaction time after the ball hike). The person who was considered the first sports psychologist was Coleman Griffith. Today, most professional teams employ sports psychologists to assist players with mental health, performance, and well-being.

Griffith began offering the first course in sports psychology in 1923, and later published the first book on the subject titled The Psychology of Coaching (1926). Unfortunately, Griffith’s lab was closed in 1932 due to lack of funds. After the lab was shut down, there was very little research on sports psychology until the subject experienced a revival of interest during the 1960s.
Unintentional weight loss can occur because of an inadequately nutritious diet relative to a person's energy needs (generally called malnutrition). Disease processes, changes in metabolism, hormonal changes, medications or other treatments, disease- or treatment-related dietary changes, or reduced appetite associated with a disease or treatment can also cause unintentional weight loss.[25][26][27][31][32][33] Poor nutrient utilization can lead to weight loss, and can be caused by fistulae in the gastrointestinal tract, diarrhea, drug-nutrient interaction, enzyme depletion and muscle atrophy.[27]
Both sport psychology (focusing on the dynamic interplay between psychological factors and athletic performance) and sport and exercise psychology (focusing on using psychological insight to increase exercise and activity levels) are essential components in empowering performance. Whether that be for professional athletes or the general population, an understanding of how the mind works can have a huge impact.
Passive-aggressive behavior is destructive and should be addressed as soon as possible (particularly when it is affecting the whole team). Don’t wait for performance evaluations—act now! Constructive feedback is a powerful tool in shaping behavior and improving performance. However, many people fail to deliver it effectively, if at all. Constructive feedback can be viewed as overly critical, or is often vague and unclear, leaving the recipient unsure of what to actually do with the feedback. In addition, in an attempt to avoid confrontation or an uncomfortable situation, people may sugarcoat the feedback by downplaying the impact or minimizing the importance of it. In the end, this serves no one.
Both views reflect CEOs’ perceptions. But those, in turn, reflect the failure of coaching programs to show that the infrastructure of successful leadership vision and behavior is heightened self-awareness about one’s motives, values, and personality traits. That’s especially true within today’s challenging, fluid environment. Because of this failure, coaching programs unknowingly collude with CEOs’ view that self-awareness is either irrelevant to leadership or of minor importance.
In 1938, Griffith returned to the sporting world to serve as a sport psychologist consultant for the Chicago Cubs. Hired by Philip Wrigley for $1,500, Griffith examined a range of factors such as: ability, personality, leadership, skill learning, and social psychological factors related to performance.[12] Griffith made rigorous analyses of players while also making suggestions for improving practice effectiveness.[14] Griffith also made several recommendations to Mr. Wrigley, including a "psychology clinic" for managers, coaches, and senior players. Wrigley offered a full-time position as a sport psychologist to Griffith but he declined the offer to focus on his son's high school education. is not intended to be a substitute for professional advice, diagnosis, medical treatment, or therapy.

Thanks for your article Nadine. There is now further evidence of the Coaching Ripple Effect in the groundbreaking research by Dr Sean O’Connor & Dr Michael Cavanagh (2013). They are in fact colleagues of Tony Grant at the University of Sydney. To give a balanced view, Tony’s article on ROI as a poor measure of coaching success (2012) is also worth a read.
"FMI's Executive Coaching provides opportunities for key leaders to identify specific areas of focus and work one on one with a coach to become stronger leaders.

It’s important to remember that depression, along with severe and chronic mental illnesses such as bipolar disorder and schizophrenia, also affect a person’s physical health. Depression is more than just feeling sad or having negative thoughts. It’s a condition where the chemicals in your brain are imbalanced. Hypnotherapy is a complementary therapy, and it shouldn’t be the only therapy a person uses to enhance their mental health.
