The importance of psychological skills training (PST) in the development of athletic performance is widely recognized. This paper is a comprehensive review of PST in elite sports, with a special focus on high-intensity sports (HIS). The reviewed literature showed a lack of convincing evidence and theoretical underpinning concerning traditional psychological skills to enhance performance in HIS. Therefore, a model with three conceptual levels (psychological demands, skills and techniques) is presented. The model facilitates the identification of the psychological demands of a specific sport, which in turn enables distinguishing which psychological skills are required. This allows an expert to choose psychological techniques to improve the athlete's psychological skill. Considerations based on our model and the limited HIS-related literature available revealed self-skills, personal development and life skills, arousal-regulation skills, volitional skills, motivational skills and recovery skills as the most important skills to address in order to enhance performance. Development of harmonious passion, in-practice integration of volitional strategies, use of associative attentional techniques, pain management techniques, use of the mindfulness-acceptance approach and the facilitative interpretation of cognitive and somatic sensations are regarded as suitable to meet the psychological demands of HIS. They are recommended for systematic application by athletes and coaches.In today's professional and semi-professional sports, the thin line between winning and losing is becoming progressively thinner. At the Beijing Olympic Games in 2008, the difference between first and fourth places in the men's rowing events averaged 1.34%, with the equivalent for women being a mere 1.03%. This increasing performance density creates massive pressure. Thus, it is not surprising that in recent years, the importance of psychological skills training (PST) has been recognized, and the number of athletes using psychological training strategies has increased. This paper aims to address the effect of PST on an athlete's performance progress, with a special focus on a group of sports involving a high-intensity load. High-intensity sport (HIS) is characterized by an impact duration between 1 and 8 min, with a very high-impact intensity and a continuous power output throughout the performance phase. Typical examples of HIS are rowing, swimming, 800 and 1500 m track and field running, track cycling and flat-water canoeing. While some authors (e.g. Mujica, 2009) state that high-intensity exercise is also crucial in team sports, this paper focuses merely on individual sports because the psychological demands in these two sport forms are very different. This paper argues that in attempting to achieve outstanding performance, PST should be adapted to the psychological and physiological demands of each discipline. Therefore, it introduces the systematization of PST and proposes a model for the identification of the psychological demands of a specific...
