The aim of this study was to investigate the relationship between core endurance and cervical stabilization and proprioception in women with and without Pilates exercise. The study was conducted with 40 volunteer female participants aged 20-50 years. The study group was selected from women who did Pilates exercises 2 days a week for at least 12 weeks under the supervision of a physiotherapist, while the control group was selected from women who did not participate in any Pilates, yoga or exercise program in the last 1 year and were sedentary according to the International Physical Activity Questionnaire. Lateral Bridge Test, Static Trunk Extension Test, Trunk Flexor Endurance Test, Cervical Joint Position Error Test, Cervical Region Deep Flexor Muscle Endurance Tests were applied to the participants and Craniocervical Flexion data of the participants were evaluated with Stabilizer Pressure Biofeedback Device and the results were recorded. These results indicate that high performance in core endurance is associated with improved performance in cervical stabilization. As a result of this study, it was concluded that Pilates has a significant effect on core endurance, cervical stabilization and proprioception in women.
