Purpose: to determine the change in physical and technical fitness of 6-7-year-old tennis players with the help of complexes of specially selected exercises. Material and methods: 12 young tennis players from Kharkiv took part in the research. Sports experience of sportsmen is 1-2 years. Classes were held 8 hours a week. To determine the current level of physical fitness, test exercises are selected: running in three directions “Fan”; run 18 m (s); long jump from the place (cm); throwing a tennis ball into the target 3m, 6m, 9m (number of hits); shuttle run 10 m per 3 times (s); slopes forward standing on the gymnastic ladder (cm). In the technical training test exercises were as follows: stuffing the ball with a bounce from the racket down, stuffing the ball with a bounce from the racket up, stuffing the ball with a racket without bouncing off the floor, game to hold the ball without error, game to hold m ' diagonal ball on the right without error, game to hold the ball diagonally on the left without error, serving from the bottom with 10 attempts.

In the technical training, specially selected exercises took into account the parallel improvement of hitting technique and the development of a sense of ball, rhythm, differentiation of efforts, coordination of movements, spatial orientation. At the second stage, a formative pedagogical experiment was conducted using the developed sets of specially selected exercises in the training process and changes in the results of test exercises were determined. Results: The need to find new, more effective, means and methods of training in modern tennis is confirmed. Drawing up individual programs and sets of specially selected exercises will help increase the training of tennis players. The current level of physical and technical fitness of tennis players is established and complexes of specially selected exercises are determined. Significant changes in the results of physical fitness were determined, except for indicators in the forward tilt p>0.05. Reliable results were also obtained in technical training, except for stuffing the ball with a racket without bouncing off the floor p>0.05. Conclusions: using the presented complexes of specially selected exercises positively influenced the changes in physical and technical fitness indicators, which allows recommending 6-7-year-old tennis players in the training process.
