<bold>Introduction.</bold> The aim of the study was to carry out a biomechanical analysis of performing key elements of sports technique of the round-off tucked back somersault by acrobats aged 10-11. <bold>Material and methods.</bold> Thirty male acrobats participated in the study. They were randomly assigned to two groups: experimental (n=15) and control (n=15). Training experiment (specially designed training program applied in the experimental group), experts' evaluation and film analysis were the methods used to evaluate effects of experiment. <bold>Results.</bold> The results of the experimental group were statistically significantly better than in the control group (p<0.05). <bold>Conclusion.</bold> Training program based on teaching and improving key elements of technique may be recommended as one of the effective ways of teaching and improving the technique of selected acrobatic exercises of a coordinationally complex movement structure.
