Background and Aim: In wrestling, the rest time between two rounds of the competition is short; therefore, these conditions these conditions cause the body to lose and not completely regenerate its energy reserves, and the person is tired and eventually prone to injury. On the other hand, such activities, which are performed with intense eccentric contractions are associated with mechanical and metabolic disorders. Therefore, the purpose of the present study was to determine the effect of short-term Inflamma-X supplementation on muscle damage and inflammatory markers following the combined SWPT-SWFT protocol in wrestlers. Materials and Methods: 24 young wrestlers were randomly divided into two supplement-exercise groups (12 people) and placebo-exercise groups (12 people). From 10 days before the implementation of the combined protocol, the wrestlers consumed two daily supplements of Inflamma-X with a dose of 15 mg or a placebo with the same amount and number as fasting. Blood samples were taken before the start of the combined protocol, immediately after the first, second and fourth stages of the protocol, and finally 48 hours after the combined protocol. Levels of keratin kinase (CK), lactate dehydrogenase (LDH), reactive protein - C(CRP) indicators were evaluated by the Eliza method. In order to analyze the data, the method of analysis of variance with combined repeated measurement was used at the significance level of p<0.05. Results: In none of the stages of blood sampling, serum CK and LDH values were not significantly different between the two groups (p<0.05). However, the serum CRP values of the supplement group in the fourth and fifth stages were significantly lower than the placebo group (p<0.05); While in the first, second and third blood sampling stages; There was no significant difference between the two groups (p<0.05). Conclusion: It seems that in wrestling competitions, the use of Inflamma-X supplement can be beneficial in the prevention of general inflammation. But more research is needed on the role of this supplement in preventing increased muscle injury markers in wrestlers.

Background and Aim: Exercising without proper recovery is likely to leave sports-related injuries or cause pain to the athletes. Therefore, the aim of present study was conducted to investigate the effect of six weeks of dedicated football training and various recovery methods on the speed, vertical jump and muscle damage of football players. Materials and Methods: Thirty six young and elite football players of Birjand city were selected purposefully and randomly divided into 4 groups of passive recovery, active recovery, floating in cold water and massage. Subjects first took a 20-meter back and forth running session to the point of exhaustion and then participated in a 20-minute recovery procedure. After that, they practiced football for 6 weeks, and then they did a session of instrument making, and at the end they participated in one of the 20-minute recovery methods. The lactate dehydrogenase (LDH) and creatine kinase (CK) indices were measured by Elisa, velocity by the double-run Bangsbo velocity test, and anaerobic power by the Sargent jump test. The results were extracted using analysis of variance with repeated measures, dependent t-test, and tuky test at the p<0.05 level. Results: Inactive recovery and massage methods following 6 weeks of special football training reduced LDH enzyme (p=0.01 & p=0.04 respectively) and massage recovery method reduced CK enzyme (p=0.001) in participants. On the other hand, cold water recovery improved athletes’ speed (p=0.01), but cold water recovery and massage methods improved vertical jump (p=0.01). Conclusion: The immersion in cold water and active recovery between training sessions accelerates the recovery of physical functions (speed and explosive power) and reduces the indicators of muscle damage (CK & LDH) of football players.

Background and Aim: The effect of resistance training and cold water immersion on muscle injury and inflammation is not clear. The aim of this study was to study the effect of 8-weeks resistance training and cold water immersion on muscle injury and inflammation responses following an acute strength activity in futsal players men. Materials and Methods: Twenty futsal players (age 26±3.07 years and body mass index 24±3.40 kg/m2) volunteered to participate in the study and were randomly assigned to experimental and control groups. After first blood sampling, both groups performed one session of acute circular resistance training with 75% of 1-RM at 5 stations, 3 sets, 8-10 repetitions, and a 90-second rest between sets and a 5-minute rest between stations. The second blood sampling was performed after 48 hours. The experimental group performed 8 weeks of circular resistance training, 3 sessions per week like the acute resistance training and immediately after exercise were immersed, 20 minutes at 5-10°C in cold water. Forty eight hours after last training session, blood sampling was performed. Then, both experimental and control groups performed the second acute circular resistance training and one hour later, the fourth blood sampling was performed. The differences of variables at different time intervals were compared with 2×4 two-way ANOVA and Independent samples t-test at p < 0.05. Cearitine kinase (CK) was measured with Iran Alpha Classic Autoanalyzer and Bionic kit; while white blood cells (WBC) count and their subclasses were measured with BC-3000 hematologic auto analyzer and China Mindry kit. The differences between the variables at different times were analyzed by 4* 2 two-way ANOVA and the differences between the two groups were determined by independent t-test at p < 0.05. Results: CK (p=0.001), WBC and neutrophils (p=0.001) significantly were increased in both groups after the first acute resistance training. After 8 weeks of resistance training-cold water immersion CK (p=0.004), WBC, neutrophils, monocytes, and lymphocytes (p=0.001) significantly decreased in experimental group as compared to the control group. 8 weeks resistance training-cold water immersion significantly decreased CK, WBC, neutrophils (p=0.001), and lymphocytes (p=0.004) in experimental group following the second acute resistance training compared to the control group. Whereas, there was no significant differences in monocytes (p < 0.05). Conclusion: Resistance training along with cold water immersion could reduce muscle damage and inflammation following acute exercise.

Background and Aim: Based on the limited and inconsistent results in regarding to the effects of intense exercise on inflammatory markers and muscle damage in adolescents, the aim of this study was to examine the response and relationship between some inflammatory markers and muscle damage in 14-16 years old boys in response to incremental physical activity. Materials and Methods: Twenty-four healthy 14-16 years old boys volunteered and divided in two groups as exercise (n=12) and control (n=12) groups. The exercise group performed incremental modified Balke protocol physical activity, according to the defined protocol. In order to examine the levels of plasma fibrinogen, Serum CRP and CPK blood samples were collected in baseline and immediately 2 minutes after incremental physical activity in trained group and also in baseline and 48 hours later in the controls group. To statistical analysis the dependent t-test, independent t-test, Pearson's correlation coefficient and beta coefficient were used and the significant level set at pResults: Serum CRP (p=0.01), CPK (p=0.01) and plasma fibrinogen (p=0.01) levels significantly increased immediately after intense exercise in the exercise group (p<0.01). Moreover, the relationship between variables showed, significant correlation between plasma fibrinogen with Serum CRP (r=0.661 p<0.016) and plasma fibrinogen with Serum CPK (r=0.617, p< 0.011) in the exercise group. Conclusions: According to results of this study the inflammatory markers and muscle damage indices were affected by intense aerobic exercise in adolescents, which indicates the presence of inflammation and muscle damage in response to intense aerobic exercise.
