Aim. This paper critically explores qualitative biomechanical analysis. The aim of the study was to investigate information entropy in the perception of sports technique. Material and methods. The research is based on expert assessments. The coaches recorded typical errors and provided their integral assessments of sports technique while watching the video of sprint running (250 fps). Results. The study showed the low correspondence between the results of qualitative biomechanical analysis provided in the form of expert assessments. The reasons for this were the subjective perception of sports technique and the uncertainty of the technique itself. The study showed that the Shannon entropy could be a suitable indicator of athletic performance. Besides that, entropy allows estimating the accuracy of formulations that describe technique errors. Conclusion. The results obtained can be used to improve qualitative biomechanical analysis by reducing information entropy in the perception of sports technique.
