摘要：Purpose: To evaluate the effects of fast weight loss (FWL) and short terms weight loss(SHWL) on the salivaryfree testosterone and cortisol and performance of young elite wrestlers. Methods: 14 wrestlers (mean age of17.79 ± 0.75 years, height of 172.06±4.61 cm, weight of 70.04 ± 8.72 kg, and BMI of 23.21 ± 2.09) whowere randomly assigned into two groups: fast-term weight loss group (FWL) (performed exercises withconventional method during 24 hours, with severe food restriction and water and using thick clothing) andshort-term weight loss group (SHWL) (performed the exercises in a 10-day program with a daily caloriereduction from 4 to 5% and exercise program included 3 sessions in which each session lasted 40 minutes)participated in this study. Exercise program by weight was also similar in both groups. The salivary freetestosterone, cortisol and function indicators were measured in two phases (pre-test and post-test). Results:The results showed that SHWL had no significant impact on hormone and functional variables (p≥0.05).Although in the FWL, time of Rockport test improved, causing to reduce aerobic fitness compared to pretest(p≤0.05), it had no significant effect on other variables (P≥0.05). Also the percentage of inter-group changesshowed no significant difference between the groups (P≥0.05). Conclusion: SHWL has some advantages overFWL, since it leads to less reduction in functional indices and athletes can participate in competitions withhigh confidence.
