Abstract
Introduction: The aim of the present study was to compare the effects of 12 weeks of aerobic training combined with salvia supplementation on the secretion of thyroid hormones and their stimulating hormone. Methods: In this quasi-experimental study, 48 young male athletes with a mean age of 20–35 years were randomly assigned into four experimental groups (12 participants each): aerobic training, aerobic training with salvia, salvia supplementation, and control. The training program lasted for 12 weeks, consisting of three sessions per week, each session lasting one hour and performed as aerobic exercises. The salvia group received three coated tablets of Salvigol (100 mg each) daily. The groups without supplementation performed only aerobic training for 12 weeks. Data analysis was conducted using descriptive and inferential statistics. The Shapiro–Wilk test was applied to assess data normality. To test the hypotheses, two-way ANOVA was employed; paired t-tests were used to compare pre- and post-test data within groups, and Tukey’s post hoc test was applied for between-group comparisons. Statistical analyses were performed using SPSS version 27 at a significance level of 0.05. Results: The findings demonstrated that 12 weeks of aerobic training combined with salvia supplementation led to a significant reduction in T3 hormone secretion and its stimulating hormone (p = 0.001). Furthermore, aerobic training with salvia supplementation had a significant effect on T4 hormone levels (p = 0.001). However, no significant changes in TRH were observed (p> 0.05). Based on the results, significant differences in T3 and T4 were found between the aerobic + salvia group and the aerobic, salvia, and control groups. Moreover, significant differences in T3 and T4 were also observed between the aerobic group and the control group. No other significant differences were detected among the remaining groups. Conclusion: Considering the beneficial properties of salvia as a supplement, its combination with exercise may exert greater effects on improving thyroid hormone secretion and its stimulating hormone.
