Changes in Lumbar Curvature and Posture Control after Six Weeks of TRX Training in Men with Lumbar Hyperlordosis: A Randomized Control Trial

چکیده مقاله

Background: Lumbar hyperlordosis is a common spinal abnormality that can negatively affect balance and physical performance. This study investigated the effect of six weeks of TRX exercises on lumbar curvature and postural control changes in men with lumbar hyperlordosis. Methods: This study was a randomized controlled trial (RCT). The population consisted of non-athlete male employees aged 18 to 30 with lumbar hyperlordosis in Quchan city. From this population, a sample of 34 participants was selected through an initial screening process using a grid board and was randomly assigned to two groups: an experimental group (n=17) and a control group (n=17). The experimental group performed TRX exercises for six weeks, three sessions per week, each lasting 60 minutes. Lumbar lordosis was measured with a flexible ruler, while the static and dynamic balance were assessed using the YBalance and static balance tests. Data analysis was performed using paired t-tests and ANCOVA in SPSS version 22. Results: The findings revealed that TRX exercises significantly reduced lumbar curvature in the experimental group compared to the control group (p=0.012). Additionally, the experimental group showed a significant improvement in static balance (p=0.007) and dynamic balance (p=0.020) compared to the control group. These improvements indicate the positive impact of TRX exercises on postural control and balance in individuals with lumbar hyperlordosis. Conclusions: The results of this study demonstrated that TRX exercises can effectively reduce lumbar curvature and improve static and dynamic balance in men with lumbar hyperlordosis. Due to the instability created during these ex
