Relationship between Transversus Abdominis Strength and Lumbar Lordosis in Young Adults

Abstract

Background: The researchers and clinicians are emphasizing on function of Transverse Abdominis (TrA) which is a deepest abdominal muscles because there is an evidence that TrA is recruited independently of the other abdominal muscles in many different tasks and plays an important role in lumbar stability. Aim: The purpose of this study was to assess the relationship between TrA muscle strength and lumbar lordosis in young adults. Methods: Total 394 subjects were recruited from the constituent institutions of Sumandeep Vidyapeeth with the age range 18-35years. All the subjects, Lumbar lordosis angle and their TrA strength were measured with the Flexicurve and Pressure Biofeedback Unit respectively. Lumbar lordosis angle was calculated using established formula. Average of 03 trials was considered for TrA strength. Results: Pearson correlation coefficient was -0.18 on correlating Lumbar lordosis angle with TrA strength, -0.09 for age with TrA strength and 0.11 for age with lumbar lordosis angle. Conclusion: This study concludes that there is negative relationship between lumbar lordosis and TrA i.e. as the lumbar lordosis angle increases, the strength of TrA muscle decreases.
