The Effect of a Spirulina Supplementation Course with Nonlinear Resistance Training On Liver Enzymes in Obese Women

Obesity is associated with a variety of diseases, including cardiovascular disease, diabetes, and fatty liver, which are a serious health threat and cause many deaths worldwide. The purpose of this study was to investigate the effect of a spirulina supplementation course with nonlinear resistance training on liver enzymes in obese women. Forty obese women in Parsian city were selected through Purposive sampling method and were randomly divided into four groups of 10 people including nonlinear resistance exercise, spirulina supplement, nonlinear resistance exercise + spirulina supplement and placebo. Interventions were performed for 8 weeks. Twenty four hours before and 48 hours after the intervention, blood samples were taken from all four groups at 12 hours fasting. For each sample, AST, ALT and ALP levels were measured. The supplement and placebo group consumed 2 capsules of spirulina daily or starch in the morning and evening meals, respectively. To compare the differences between variables in study groups and blood sampling times, mixed ANOVA was used. The results showed that there was no significant difference in AST (p = 0.25), ALT (p = 0.92) and ALP (p = 0.76) enzymes between groups. According to the results of this study, it can be concluded that eight weeks of nonlinear resistance training and spirulina supplementation have no effect on the liver enzymes in obese women and thus do not improve the enzymatic markers of their liver function. Inadequate training and supplement intake and lack of proper diet control may be the reason for lack of improvement.
