Extremely skilled, predefined movement patterns are embedded in memory and accessed with exceptional confidence, often under incredible levels of pressure, anxiety and expectation. However, sometimes it happens that some "triggers" occur that trigger anxiety and prevent the performance of those, almost automated skills. This phenomenon is called differently in different sports, and in gymnastics it is most often associated with the term lost movement syndrome (LMS) or mental blocks and twisties. Interviews were conducted on a sample of 8 elite female gymnasts with the aim of determining the occurrence, causes and ways of solving the problem of mental blocks. The results determined that all the respondents were suddenly affected by mental blocks, most often several times during their gymnastics career. The representation of elements affected by mental blocks differed among the gymnasts, as did the duration of the mental block. What they had in common was that they predominantly had mental blocks when performing elements backwards. The most common cause of mental blockage was learning new elements too quickly, and the main manifestation of mental blockage was fear and anxiety, as well as avoiding performing the blocked element during training. The treatment methods used by the respondents were different, and the most common thing that helped was moving away from the blocked element and/or the gym.
