The problem of increasing the effectiveness of the teacher’s educational activities is largely related to how actualized and developed his professional and personal individuality is. In this regard, pedagogical technique and biomechanics are often underestimated. On the contrary, the elements of pedagogical technique are considered a consequence of the manifestation of the teacher’s individuality. In this article, the task is to identify the potential of theatrical and sports biomechanics in the development of the teacher’s personality in order for him to carry out effective educational activities. As a result of the study, biomechanical indicators of the educator were determined, allowing to assess the probabilistic characteristics of the success of his educational activities.
