Aim: In this study, it was aimed to examine the effects of static and dynamic core exercises applied to 10-12 years old female volleyball players on balance, vertical jump, agility and flexibility performances. Method: The mean age of the experimental group (EG) was 11.46±.51 years, the mean body weight was 38.38±12.02 kg, the mean height was 144,06±8.99 cm, the mean age of the control group (CG) was 11.53±.51 years. The average body weight of the thirty female volleyball players participating in the study as volunteers was 38.48±7.99 kg, the average height was 147.93±12.70 cm, and the training age was 3±1.2 years. The athletes participating in the research were randomly divided into two groups as control and experimental groups. Different training programs were applied to these groups. (EG), in addition to regular volleyball training, static and dynamic core training was performed 3 times a week for 30 minutes for 8 weeks. While (CG) only weekly regular volleyball training was applied. Pre-test measurements (balance, vertical jump, agility and flexibility) of both groups were performed before the studies. At the end of 8 weeks, the last test measurements of the groups were taken. To compare the pre and post values of the groups separately (2x2) repeated ANOVA was used. Results: The first and last test measurements of the groups were compared between the groups; According to the analysis of the data, a statistically significant difference was observed in the measurement values of the balance test, vertical jump test, agility test and flexibility test (p<0.05). Conclusion: In addition to regular volleyball training, dynamic and static core programs applied within the scope of conditioning studies contributed positively to some measured motor development characteristics of the athletes.
