The Effect of Eight Weeks of Aerobic Exercise and Spirulina Supplementation on Some Liver Enzymes, Body Composition, and Cardiorespiratory Fitness in Overweight and Obese Adult Women.

This article focuses on a randomized, double-blind, placebo-controlled trial investigating the effects of eight weeks of aerobic exercise and Spirulina supplementation on liver enzymes, body composition, and cardiorespiratory fitness in overweight and obese women. The study found that both interventions independently and synergistically improved liver enzyme levels—particularly alanine aminotransferase (ALT)—body weight, body mass index (BMI), waist-to-hip ratio (WHR), and estimated maximal oxygen uptake (VO2max). Aerobic exercise showed the greatest impact on reducing body weight and BMI, while Spirulina supplementation alone significantly improved liver enzyme markers and WHR. Although changes in liver enzymes remained within normal clinical ranges, the findings suggest potential early benefits for metabolic health, warranting further research to clarify mechanisms and long-term effects.
