Abstract

Introduction: Lumbar hyperlordosis is a common problem among athletes, characterized by an excessive increase in the lumbar arch which can lead to chronic Low Back Pain (LBP). The central stabilizing muscles of the trunk are crucial for maintaining proper stability and alignment of the spine. Weakness in these muscles can increase the lumbar arch's severity and associated pain. This study aimed to investigate the correlation between the endurance of different groups of core stability muscles and pain in women athletes with lumbar hyperlordosis. Materials and Methods: 36 female athletes with lumbar hyperlordosis were randomly selected and examined. The study assessed the endurance of the different central stability muscles, including trunk flexors, extensors, and lateral flexors, using McGill tests. Additionally, the athletes' level of LBP was measured using the Visual Analog Scale (VAS). Data analysis used multiple linear regression to assess the correlation between muscle endurance and pain. Results: None of the endurance variables of the four central stability muscles are significantly associated with the pain of subjects with hyperlordosis (P³0.05). According to the reported beta values, the endurance of the muscles of the trunk extensor, left lateral flexor, right lateral flexor, and trunk flexor have the greatest association with LBP of athletes with lumbar hyperlordosis (P³0.05). Conclusion: These findings suggest that increasing the endurance of the central stabilizing muscles, could not significantly reduce LBP in athletes with lumbar hyperlordosis, for this reason, there is no need to separate the strengthening of the core muscles to reduce  LBP These results could be used to develop targeted exercise programs to correct posture and reduce pain in this population.
