Introduction. The aim of the study was to assess the efficiency of learning complex movement tasks with the use of different types of verbal feedback. Material and methods. Thirteen students randomly assigned to two groups (E&P=7; P=6) took part in the study. Results. In learning a movement task verbal information on errors and correctness (E&P) was more efficient than verbal information on correctness (P). Conclusion. At early stages too much information hinders the process of learning.

Introduction. 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. Material and methods. 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. Results. The results of the experimental group were statistically significantly better than in the control group (p<0.05). Conclusion. 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.
