The aim of this study is to examine the Effects of Core Training on Balance and Jumping in Volleyball. 16 athletes who were licensed and interest in volleyball branch in Tosya District of Kastamonu Province participated in the study voluntarily. This athletes included in the study were randomly divided in to two groups as the study group (8) and the control group (8).

The normality dist rebution of the data was determinet by the Shapiro Wilk Test. Wilcoxon and Mann-Whitney U Test were used in the analysis of the data.
