Abstract

Introduction: Lumbar hyperlordosis is a common problem among athletes, characterized by an excessive increase in the lumbar arch, and it can lead to chronic back pain. 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 investigated the correlation between the endurance of different groups of core stability muscles and pain in athletes with lumbar hyperlordosis. 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 back pain was measured using the visual analog scale (VAS). Data analysis involved using multiple linear regression to assess the correlation between muscle endurance and pain. Results: The results of multiple linear regression analysis indicated that there is no significant association between the endurance of any of the core stability muscle groups (including extensors, flexors, and lateral flexors) and pain (P≤0.05). Conclusion: These findings suggest that strengthening the central stabilizing muscles, particularly the lumbar extensors, could play a significant role in reducing back pain in athletes with lumbar hyperlordosis. These results could be used to develop targeted exercise programs aimed at improving posture and reducing pain in this population.
