Aim: To examine the effects of coordination applied to 8-10 years old female athletes on tennis and some motor skills.

Metodology: The athletes were randomly divided into experiment and control groups by applying Dewitt-Dugan tennis test, standing long jump, vertical jump, 20m speed, T test and square test. In the study, while the control group only participated in club training for 8 weeks, 5 days a week and 60 min.and the experimental group added coordination training education. Data was collected and entered in SPSS 22.0.

Results: There was a significant difference (p<0.05) in the parameters of all measurements of the experimental group in the standing long jump, vertical jump, 20m speed, t test and Dewitt-Dugan parameters and no significant change in the square test results (p>0.05). Among the final measurement values of the experimental and control groups, significant differences were found in favor of the experimental group in the values of standing long jump, vertical jump, 20m speed and Dewitt-Dugan parameters, except for the T test and the square test (p<0.05).

Conclusion: It can be said that the 8-week coordination training applied to the experimental group has a positive effect on the motor characteristics and tennis skill, and specific coordination movements added to each unit training can be beneficial for the athletes.
