In this study; It was aimed to determine the effect of the core training program applied for 4 weeks on some physical characteristics in faculty of sport science's students. A total of 23 male athletes, 19-27 age groups, who are studying at Firat University Sports Sciences Faculty voluntarily, participated in the research group. Participants were divided randomly into two groups: training (n: 12) and control (n: 11). Body weight, Body Mass Index (BMI), dominant hand grip strength, back and leg strengths, vertical jump and 20m sprint measurements were taken before and after the four week core training program. The obtained data were analyzed using the SPSS 22 packet program and Paired Samples t test was used to determine the difference between the pre-post test and the Independent Samples t test was used to determine differences between groups. As a result of the analysis of the obtained data, there was no significant difference between the groups when the control and the training group were compared (p>0,05). While no significant differences were found between pre-test and posttest data of control group in intra-group comparisons, it was determined that the training group had significant differences in dominant hand grip strength, back and leg strength and vertical jump values (p<0,05), but there was no difference in sprint, body weight and BMI values (p>0,05). As a result, it has been shown that core training which is applied for 4 weeks and 3 days a week has significant increases in back and leg strength, vertical jump and hand grip strength values. Consequently, the application of core training programs may be suggested to provide positive effects on performance and physical fitness parameters.
