Objective: The present study was carried out to determine the effect of creatine loading on some delayed onset muscle soreness (DOMS) indices (biochemical, functional and superficial) following resistance exercise in male wrestler. Methodology: Eighteen volunteer male wrestler (age 21.11±1.13 years, body fat 12.67±1.84 %, and BMI 21.96±0.70 kg.m2) were assigned to a randomized and double-blind into two equal creatine (n=10) and placebo (n=10) groups. After six consecutive days supplementation (300 mg.kg-1.day body weight creatine or dextrose), all subjects were participated in one single- session circuit resistance exercise protocol (with 80% 1-RM in 3 sets with 6 repetition) include six station. Changes in muscle soreness indices were determined in three phases (before supplementation phase, immediately and 24 hours after the resistance exercise protocol). Data were analyzed by repeated measure ANOVA, Bonferroni and independent T test at P≤0.05. Results: The results show that the one-session resistance exercise protocol significantly increased the creatine kinase (CK) and perceived muscle soreness index (P≤0.05). Although, the 24-hour of serum CK change ranges in creatine group were significantly less than in placebo group (P≤0.05). While, the 24-hour differences of lower limb’s swelling, flexibility, maximal isometric strength, and explosive power between two groups were not significant. Conclusion: The results of this study showed that the short-term creatine loading leads to attenuate the adverse effects of undesirable muscle soreness indices (serum total CK). Therefore, based on the present results, that creatine loading could reduce the muscle soreness ranges following the resistance exercise.

Abstract
Aim: The aim of this study was to determine the effect of one-bout exhaustive resistance exercise on some muscular damage markers in serum of male volleyball players after different dosage of caffeine intake.
Method: Thirty male volleyball players (mean aged 21.47±1.45 years, fat 10.47±3.11 % and BMI 23.15±1.26 kg.m2) in a randomized semi experiment and double-blind design were allocated in three groups: supplementing groups (with 6 and 9 mg.kg-1 caffeine) and placebo group (6 mg.kg-1 dextrose). After the supplementation, all subjects were participated in one-single-session resistance weight-training (with 80% of one repetition maximum until exhaustion). Changes in muscular damage indices (total serum CK and LDH) were determined in three phases (Baseline, immediately and 24 hours after the training protocol). The normal data were analyzed by repeated measure ANOVA and Bonferroni at P≤0.05.
Results: The results showed different dosage of caffeine intake had no significant effect on increased level of muscular damage serum enzymes immediately after exercise compared with the placebo group. Also, exhaustive resistance exercise increased levels of 24-hour CK and LDH significantly in all groups (P≤0.05). However, different dosage of caffeine intake had not effect on increased levels of muscle damage markers after 24 hours of exercise.
Conclusion: Based on the present findings and the execss intake of different dosage of caffeine probabley can not prevent further damage and in intraction with resistante exercise can not lead to escalation the indirect indices of muscle damage in compared with the placebo group.
