The purpose of this study was to determine the effect of life kinetic number training on the concentration level of female volleyball athletes aged 13-15 years. This study used an experimental method with a one group pretest-postest design. The sample in this study amounted to 22 athletes, which was taken through purposive sampling techniques. Data collection techniques in this study are tests and measurements. The instrument in this study uses a concentration test, namely the concentration grid test. The data analysis technique uses a t test (Paired Sample Test) which is analyzed using SPSS 25. The results of this study showed that the calculated t value of 13.791 was greater than the table t of 2.080, and the paired sample t test showed that the result of Sig. (2-tailed) 0.000 was less than 0.05 which means that there was a significant influence between life kinetic number training on the concentration level of female volleyball athletes aged 13-15 years. So it can be concluded in this study that life kinetic number training is one of the most effective exercise models in order to increase the concentration of female volleyball athletes aged 13-15. © Federación Española de Asociaciones de Docentes de Educación Física (FEADEF).
