A contemporary demands in adrenaline sport activities emphasize risk, danger and adrenaline on one hand, and desire for individual feelings of happiness on the other hand. The study analysed if sport climbing can influence common feelings and psychological states, in terms of proportional representation of the selected positive and negative indicators. The purpose of the study was to characterize experiencing in climbing and to find out psychological effects of a 3-month sport climbing course on individualized experiences and feelings. Qualitative changes were evaluated on a standardized scale SUPSO, in 46 respondents (aged 23.5±1.8 years). The method is based on verbalization of inner feelings, states and their expressions. The results were converted and calculated in proportions of the given positive and negative indicators. The significance of change was evaluated in quantitative analysis (Wilcoxon pair test, α0.05) by IBM SPSS Statistics 24. The results verified positive psychological effects of sport climbing. The change was manifested by significant difference between common and actualized psychological states and feelings. There was a statistically significant difference in all positive (wellbeing and activeness) and majority (80 %) of negative indicators (impulsiveness, discomfort and restlessness, anxious expectations, and sadness). Significant difference in depression and exhaustion was not confirmed. Climbing was described as a demanding adventure sport activity that combines physical and psychological features. Way and authenticity of experiencing can differ among individual climbing disciplines. The research showed that even sport climbing, which is considered to be performance-oriented, can positively influence psychological states and feelings.
