The purpose of this randomized controlled trial is to assess if Mindful Sport Performance Enhancement (MSPE) is beneficial to collegiate athletes. Participants were 52 NCAA Division III student athletes who underwent six MSPE sessions incorporating mindfulness and non-judgmental acceptance. In addition, improvement in flow, trait mindfulness, life satisfaction, and self-rated sport performance was significantly higher in the treatment group compared to the control group. Therefore, the findings suggest that MSPE may potentially be used as a way to enhance psychological wellbeing and athletic performance. Therefore, the results of this study offer support to the application of MBIs in sports in supporting the psychological health and performance of athletes.

The purpose of this study is to investigate the relationship between the level of mental toughness and self-compassion in elite Canadian female athletes. Using thematic analysis of the interviews, this study found that mental toughness and self-compassion are the two crucial variables for managing adversity in sport. Mental toughness was seen as an element in the realms of endurance and competition preparation, whereas self-compassion provided maintenance for a well-balanced and mindful attitude. It is suggested by the study that a combination of self-compassion with mental toughness may result in developing a healthy mindset, very crucial in sports. As a contribution to sports psychology, this paper goes a step further to identify the importance of self-compassion and mental toughness.

The purpose of the randomized controlled trial is to determine whether Mindful Sport Performance Enhancement (MSPE) works for college athletes. Fifty-two NCAA Division III student-athletes received six sessions of MSPE grounded in mindfulness and nonjudging acceptance. At the same time, the treatment group showed a significantly greater improvement in flow, trait mindfulness, life satisfaction, and self-rated sport performance than the control group. Thus, the findings are stacked toward the plausibility of MSPE in psychological health improvement and sporting achievement. On these grounds, the study presents evidence of the application of MBIs in sports to help athletes achieve both psychological well-being and optimum performance.

This intervention study focuses on the effects of self-talk (ST) training on competitive anxiety, self-efficacy, volitional skills, and performance in junior sub-elite athletes. This study recruited 117 athletes and divided them into the short-term ST group, the long-term ST group, and the control group. The findings showed that ST training was useful for decreasing somatic anxiety and for increasing self-confidence, self-efficacy, and performance, particularly when participants underwent long-term training. In doing so, this research demonstrates the effectiveness of ST interventions in enhancing young athletes’ psychological conditions and performance and gives concrete suggestions for coaches and sport psychologists.

The study in question examines psychological characteristics affecting basketball players especially focusing on psychological quality. The research establishes personality, stress, and psychological capital (PsyCap) as factors that define success in sport. In the quantitative research method, questionnaires were administered to 100 basketball players to determine the relationship between the components of PsyCap and performance including self-efficacy, hope, optimism and resilience. It was established that PsyCap enhances performance and it is recommended that psychological training should be offered to athletes. In conclusion, this paper offers a better understanding of psychological aspects of sports and the need to nurture athletes’ mental abilities.

This systematic review integrates 30 meta analyses on the effect of sport psychology intervention on sporting performance. It touches on different psychological aspects including cohesiveness, self-confidence, and attentiveness suggesting moderate positive impact on performance (Hedge’s d = 0. 51). Maladaptive constructs such as cognitive anxiety and depression had a modest negative impact (d = -. 21). Furthermore, the review focuses on the efficiency of sport psychology interventions in the context of performance improvement and offers a practical reference for exercise professionals. This study is important for comprehending the effects of psychological treatments on sports performance in general.

The following meta-analysis focuses on the connection between the Profile of Mood States (POMS) and athletic performance in 25 studies. The study emphasizes on the impact of mood states such as tension, depression, anger, vigor, fatigue and confusion on the outcome of performance. These findings suggest that TMD is valid for predicting performance, especially in different mood conditions. The results presented in the paper prove that the reader can use the mental health model or the iceberg profile to enhance the performance of the athletes.

Effects of mindfulness-based interventions on promoting athletic performance and related factors among athletes: a systematic review and meta-analysis of randomized controlled trial. International Journal of Environmental Research and Public Health, 20(3), 2038.

This systematic review and meta-analysis aimed to assess the effects of mindfulness-based interventions (MBIs) on performance and psychological responses in athletes. The review involved 32 RCTs, and meta-analysis results indicated increased mindfulness and mindfulness-related psychological processes of athletes. However, none concerning the mental health outcomes were identified in the study. This work offers empirical support for applying MBIs in enhancing performance and well-being, which suggests that mindfulness approaches may be useful for athletes. Yet, this study calls for the need to perform more well-done RCTs to determine the efficacy of MBIs in sports.

This study is a randomized controlled design that investigates the effectiveness of Mindful Sport Performance Enhancement (MSPE) and Psychological Skills Training (PST) in collegiate track and field athletes. The subjects of the study were 24 athletes, both groups showed a positive change in sport anxiety, enjoyment, and performance satisfaction. MSPE group indicated greater changes in satisfaction with sport performance compared to PST. Further analysis of the qualitative responses showed that both interventions were perceived to be positive for sport and for everyday life, but differences between the two programs were observed. The findings of this research demonstrate that mindfulness-based treatments and psychological skills training can increase performance and well-being in sports.
