The aim of the study was to evaluate the effects of the dry-land power training on swimming force, swimming performance and strength in youth swimmers. Twenty six male swimmers, free from injuries and training regularly at least 6 times a week, were enrolled in the study and randomly assigned to one of two groups: experimental (n=14, mean age 14.0 ± 0.5 yrs, mean height 1.67±0.08 m and mean body mass 55.71 ±9.55 kg) and control (n=12, mean age 14.1 ± 0.5 yrs, mean height 1.61±0.11 m and mean body mass 49.07 ±8.25 kg). The experimental group took part in a combined swimming and dry-land power training. The control group took part in swimming training only. The training programmes in water included a dominant aerobic work in front crawl. In this research the experimental group tended to present slightly greater improvements in sprint performance. However, the stroke frequency insignificantly decreased (-4.30%, p>0.05) in the experimental group and increased (6.28%, p>0.05) in the control group. The distance per stroke insignificantly increased in the experimental group (5.98%, p>0.05) and insignificantly decreased in the control group (-5.36%, p>0.05). A significant improvement of tethered swimming force for the experimental group (9.64%, p<0.02) was found, whereas the increase was not statistically significant in the control group (2.86%, p>0.05). The main data cannot clearly state that power training allowed an enhancement in swimming performance, although a tendency to improve swimming performance in tethered swimming was noticed.

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.
