The survey was conducted using the Mindful Attention Awareness Scale (MAAS-15) and the Depression, Anxiety and Stress Scale (DASS-21). The study involved 371 Lithuanian kyokushin karate athletes (of which 59.3% were male and 40.7% were female; 71.4% of research participants have practiced this sport for 11 and more years and have the 1st dan or a higher belt). The results of the study showed a positive impact of mindfulness in reducing stress experienced by athletes, improving their psychological state, and enhancing their athletic performance. A moderate negative correlation was identified between stress, anxiety, and mindfulness, and while the mindfulness score was increasing, the severity level of depression was decreasing. Meanwhile, the correlation of the meditation effect and anxiety with kyokushin karate 0-7 kyu belt was very weak but statistically significant. The research results could be useful not only for athletes and their coaches but also for sports organizations. After analysing the benefits of mindfulness for kyokushin karate athletes, mindfulness practices are proposed for the effective improvement of athletes' physical and psychological state when preparing for professional-level competitions.
