Abstract

Aim:  The aim of this study is examine effects of different concurrent training protocols on muscle strength, Testosterone and cortisol serum levels in young wrestlers. Methods:  41 young men (18-25 year-old) were randomly divided in 5 groups: 1.endurance-strength training with 8 hours inter-Session recovery (ES8) 2.Strength- endurance training with 8 hours inter-Session recovery (SE8) 3.Strength- endurance training without recovery (SE0) 4.Endurance-strength training without recovery (ES0) 5.Control (CON). The experimental groups performed Strength training 4-8 repetitions ،85-100% 1RM and endurance training with running 10-30 minutes at 70-85 percent of final speed of IFT 30-15 test. Frequency of Session was three times a week for eight weeks. The blood sampling was performed after 12 hours fasting in 8-9 am to evaluate serum cortisol (C) and testosterone (T) concentration. One–way ANOVA and paired t-test was applied for examining training effects (α=0.05) and η2 for evaluate effect size. Results:  The result of study showed that significant difference was between SE8 with SE0, ES0 and CON on lower body strength (p=0.04, p=0.004, p=0.004). Lower body strength improved after ES8, SE8 training (10% and 17%). Upper body strength increased after ES8, SE8, and SE0 with no difference between the groups (5%, 10% and 4%). Conclusion:  Cortisol concentration decreased in SE8 (-8%). The results indicate that performing strength and endurance training with 8 hours recovery between training could improve upper and lower body strength in young wrestlers.
