The aim of this study was to investigate the effect of core training on basic motoric characteristics of 12-year-old football players. Method: 40 male football players in the 12-year-old team of Erzurum Spor FK were included in this study. Height, weight, flexibility, 10 m sprint, 30 m sprint, vertical jump, standing long jump, flamingo balance test, agility, push-up, sit-up, hand claw right, hand claw left performance measurement tests were taken. The participants were measured before the season and pre-test values were taken. Core training was applied for eight weeks to the young footballers whose pre-tests were taken and their final values were recorded. Statistical analyses of the study were performed with SPSS 25.0 package programme. Paired-Samples t-test was used for pre-test and post-test analyses. The findings obtained were evaluated at 95% confidence interval level. Descriptive statistical analysis methods were used to analyse the age, height and weight values of the participants. Results: There was a significant difference between the pre and post tests of flexibility, 10 m sprint, 30 m sprint, vertical jump, standing long jump, flamingo balance test, agility, push-ups, sit-ups, hand claw right, hand claw left performance measurements. Conclusion: Although eight weeks of football training improved the basic motoric characteristics of 12-year-old football players, the application of core exercises in addition to football training showed a better improvement on basic motoric characteristics.
