| Abstract Background: Given the popularity of strength training and creatine supplementation among middle-aged athletes, investigating the combined effects of these interventions on liver health is of great importance. This study aimed to investigate the effect of eight weeks of strength training with creatine supplementation on liver function indices in middle-aged male athletes. Methods: In this quasi-experimental study with a pre-test-post-test design, 48 healthy male athletes (aged 30-45 years) were voluntarily selected and randomly assigned to four groups of 12: 1) Combined (strength training + creatine), 2) Training (strength training + placebo), 3) Supplement (creatine only), and 4) Control. The training protocol consisted of three sessions per week for eight weeks. The supplement and combined groups received 5 g/day of creatine (following a one-week loading phase), while the other groups received a placebo. Liver function indices, including Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), and Total Bilirubin, were measured before and after the intervention. Data were analyzed using paired t-tests and ANCOVA at a significance level of P<0.05. Results: The results showed that, compared to the pre-test, both the training and combined groups had a significant decrease in ALT, AST, and ALP levels (P<0.05). However, the magnitude of reduction in the combined group was significantly greater than in the training group (P<0.01). Total bilirubin showed a significant decrease only in the combined group (P<0.05). No significant changes were observed in any of the indices in the supplement and control groups. Conclusion: The combination of strength training and creatine supplementation has a synergistic effect on improving liver function indices in middle-aged male athletes. This approach can be used as a safe and effective strategy to promote liver health in this population. |
