Abstract :
Background: Liver disease is one of the most serious chronic diseases, where inactivity, obesity and lack of antioxidants in the diet are the main causes of this disease. This research investigates the effect of combined exercise and chromium supplements on body composition and liver risk factors in obese men.
Materials and Methods: In this semi-experimental research, 40 obese men (20 to 30 years old) with a six-month history of bodybuilding training were selected as research samples and randomly divided into 4 groups (exercise, supplement, exercise + supplement, control). Combined exercises for six weeks, three sessions a week, each session 60 minutes. At first, strength exercises (3 upper body movements and 3 lower body movements) were performed in 3 sets with 8 repetitions and 80% 1RM, and then aerobic exercise (1.5 miles It was done with 70% to 80% of maximum heart rate (on a treadmill). During this period, 200 micrograms of chromium supplement were given to the supplement groups. A two-way variance analysis was used at a significance level of p≤ 0.05.
Results: The research showed a significant decrease in fat percentage, abdominal circumference, alanine aminotransferase and alkaline phosphatase in obese men after performing combined exercises and consuming chromium supplements.
Conclusion: Combined exercise and chromium supplementation alone can improve liver indices and improve body composition. However, the combination of exercise and chromium supplementation improves body composition and reduces liver enzymes in obese men.
