Objective of the study is to identify the relationship between physical fitness indicators and the effectiveness of competitive activity of 13-15 year old basketball players to optimize the training process.
Methods and structure of the study. The testing involved 118 athletes from 16 Chinese teams aged 14.79 ± 1.1 years. Seven tests were used to assess physical fitness: 1-minute torso lifting, jumping rope, 15×17 meter shuttle run, 21 meter acceleration, sitting bend, defensive stance movements, and high-speed dribbling. Competitive activity indicators included the team's place, points scored, number and percentage of field goals, interceptions, fouls, and overall assessment of game activity.
Results and conclusions. Statistically significant relationships were found between coordination abilities, speed qualities, technical skills and competitive efficiency indicators. The results of the study confirm the need for an integrated approach to the physical training of young basketball players with an emphasis on the development of coordination abilities and technical skills.

Keywords: basketball, young athletes, physical fitness, competitive activity, correlation analysis, coordination abilities, speed qualities, technical training, sports performance.
