Effect of Physical and Flexibility Exercise on Plasma Levels of Some Liver Enzymes and Biomolecules of Young Nigerian Adults

Purpose: To evaluate the effect of physical and flexibility exercise on plasma levels of some liver enzymes and biomolecules of young Nigerian adults.Methods: Participants were subjected to a 2-h daily continuous physical and flexibility exercise for 6 weeks. Pre- and post-exercise blood samples were obtained and the effect of exercise on plasma levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), gamma glutamyl transferase (GGT), total protein, albumin and bilirubin, were determined.Results: AST and LDH values increased significantly (p ˂ 0.05) in males, while only AST values increased significantly (p ˂ 0.05) in females post-exercise. ALT, ALP, GGT and bilirubin values for both sexes were not significantly (p˃0.05) altered post-exercise. Post-exercise values of total protein and albumin decreased significantly (p ˂ 0.05) in males, but not in females.Conclusion: The 6-week physical and flexibility exercise did not substantially affect the plasma levels of some liver enzymes and the composition of other biomolecules.Keywords: Physical and flexibility exercise, Liver enzymes, Biochemical profile
