Effect of 8 Weeks of Selected Corrective Exercises on the Lumbar Lordosis Angle and Lower Limb Function in Non-Athlete Men with Lumbar Hyper Lordosis

Background and Objectives: Changes in the lumbar spine can affect the function of other parts of the body, including the lower limbs, and correcting these adverse changes may be able to improve function. Therefore, the aim of the present study was to investigate the effect of 8 weeks of corrective exercises on the lumbar lordosis angle and lower limb function in non-athlete men with lumbar hyper lordosis.Materials and Methods: In the present study, 26 men aged 18 to 25 years in Tehran city with lumbar hyper lordosis (greater than or equal to 51 degrees), with a mean age of 21.69±2.58 years, weight 70.56±8.66 kg and height 177.35 ± 8.01 cm was purposefully selected as study samples. Then the samples randomly divided into two groups (experimental: 13 N, control: 13 N). The lumbar lordosis angle was assessed using a flexible ruler and lower limb function through Triple hop for distance, Sargent jumping and Sixmeter timed hop was assessed in two stages, pre-test and post-test. The paired sample t-test SPSS was used to examine the whit in-group changes and the independent sample t test was used to compare the between group differences. Results: The results of this study showed that the corrective exercises group had significantly better performance in lumbar lordosis angle and lower limb function in the post-test compared to the pre-test (P <0.05) but in the control group there was no significant difference between the two test stages (P> 0.05). Also, the comparison of lumbar lordosis angle and lower limb function in post-test, indicated a significant difference between experimental and control groups (P <0.05).Conclusion: Based on the results of this study, we conclude that corrective exercises are useful in improving lumbar lordosis angle and lower limb function in people with lumbar hyper lordosis.
