Background: Core stability training has become a popular fitness practice that is already being used in rehabilitation and sports medicine programs. Core stability training is the basic and fundamental component of many comprehensive functional rehabilitation programs. In the late 1990s, core stability training was created based upon findings from large number of studies which demonstrated the significance of trunk control in neuromuscular reorganization in managing back pain. Core stability training programs are designed to help an individual to gain functional strength, neuromuscular control and the endurance of core muscles. Although most previous studies about core stability training were conducted to evaluate pain and function and only a few studies are considering pelvic parameters changes. Aim of the study: The purpose of the study was to investigate lumbopelvic sagittal alignment in asymptomatic subjects after the segmental lumbopelvic training exercises. Subjects and Methods: 13 asymptomatic subjects (8 males and 5 females) aged 20-30 years and body mass index ranged from 18.5-25 kg/cm2 were recruited for this experimental study. The pelvic parameters examined in this study were lumber lordosis angle (LL) and pelvic tilt angle (PT), pelvic incidence angle (PI) and sacral slope (SS) measured by X-ray imaging radiography from sagittal. T-test was used to detect differences in the mean values of pelvic parameters before and after exercise training. Results: T-test Statistical analysis was used to detect differences in in mean value of lumber lordosis angle, pelvic tilt angle, pelvic incidence angle and sacral slope angle before and after segmental lumpopelvic training exercise. There were no significant differences between lumber lordosis angle (t = -1.12, p = 0.13), pelvic tilt angle (t= -1.16, p = 0.12), pelvic incidence angle (t = -0.33, p = 0.37) and sacral slope angle (t = 0.22, p = 0.41) before and after segmental lumpopelvic training exercise. Conclusion: there was no significance difference in the mean value of pelvic parameters before and after segmental lumbopelvic exercise training.
