The findings of a study conducted on weightlifters between the ages of 15 and 16 at the EIDE "Captain Orestes Acosta" in Santiago de Cuba are compiled in this paper. From the application of methods and techniques to training and competitions, such as observations, semi-structured interviews with athletes and coaches, the Inventory of Psychological Performance, the Attitude Test for Competition, the Inventory of Evaluation of Error in Performance, and others; It was discovered that these athletes failed to successfully complete the lifts, resulting in a high level of tension, insecurity, and nervousness, among other negative psychological manifestations that harmed the athlete's performance and were connected to irrational or maladaptive beliefs and thoughts. An action plan was put into place with the help of the psychologist, coaches, athletes, and family members to help solve this problem. It was an open, adaptable, active, practical, and experiential group. The cognitive restructuring of dysfunctional ideas and thoughts that prevent adequate sports performance demonstrated its effectiveness.
