Litvinenko Yu.V. Basic provision of the efficiency program aimed to improve the sculling movement technique in athletes in synchronized swimming. Aim: to develop a program for improving the technique of motor activities sports with complicated structure of movements and to test its effectiveness (on the material of synchronized swimming) Material and Methods: theoretical analysis and generalization of literature data, pedagogical experiment, anthropometry, methods of recording and analyzing the movements, quality control and mathematical statistics. Results: grounded and experimentally tested program aimed at improving the “standard” sculling movement technique in “horizontal” basic positions in the mandatory program for athletes 11-12 years old, specializing in synchronized swimming. Conclusions: as a result of the formative experiment the experts’ evaluation for the implementation of the experiment of “horizontal” basic positions in athletes of the experimental group was significantly increased (p<0.05).Positive changes in the experimental group were also noted in terms of biomechanical structure of the technique. The nature of the marked changes is associated with characteristics of approaching motor action to the second method of the “standard” sculling movement.
