Abstract
<jats:p>One of the directions in the technical and tactical training of tennis players is the improvement of techniques in difficult conditions of an unstable surface, which requires athletes to have a high level of dynamic and static balance of the body when performing strokes. The purpose of the article is to investigate changes in the indicators of technical and special physical fitness in tennis players 7-8 years old under the influence of specially selected exercises on a balance platform. Sports experience of athletes is 2-3 years. Classes were held for 8 hours on Sunday. The duration of the training session was 90 minutes. The study took place for 10 weeks. Research methods: theoretical analysis of scientific and methodological literary sources; pedagogical testing of indicators: special physical and technical fitness; pedagogical experiment; Methods of mathematical statistics. Results: Initial testing determined the level of special physical and technical fitness in tennis players 7-8 years old as average. Complex 1 was used partially at the end of the preparatory part of the workout and in physical training classes. Sets of exercises 2 and 3 were used at the end of the preparatory part and the main part of the training session. After the use of complexes of specially selected exercises on the balance platform, at the end of the study, a significant increase in the results in technical and special physical fitness was obtained, which indicates the effectiveness of the implemented complexes (<0.05; <0.001). In correlation analysis, strong relationships were found in bounce strikes along the line r=0.89 and diagonally from right to right r=0.89. The results of the correlation analysis confirmed positive changes in the indicators of technical preparedness in rebound shots.</jats:p>
