Journal Article 2019 11 26 <strong>Aim: </strong>Oral supplements are common among athletes to relieve muscle damage from exercise. Recent studies have shown that bovine colostrum has antioxidant properties. The purpose of this study was to investigate the effect of 2-weeks colostrum supplementation on muscle injury indices following a session of acute resistance activity on wrestlers in Sistan and Baluchestan province.<strong> Methods:</strong> 30 wrestlers were selected voluntarily with the age range of 19 to 30 years with no sports injury in the past six months, with three sessions of exercise per week and at least three years of sporting experience. The present study was performed with an experimental group (n = 15) and a control group (n = 15) in the pre-competition season. Subjects in the experimental group performed an acute resistance exercise consisting of eight stations in three sets of 8 to 10 repetitions with 80% of one repetition maximum (1RM) and one-minute rest between stations and two minutes rest between sets. Subjects in the experimental group took 20 gram of colostrum powder with 200 ml water for two weeks, every other day. Blood samples were taken from all subjects after 10 hours of overnight fasting in three stages: 1. Before supplementation, 2. 24 hours after completing supplementation, 3. 24 hours after resistance activity session. Data analysis was done by ANOVA with repeated measures and two-way analysis of variance tests using SPSS software at the significant level of 0.05. <strong>Results:</strong> the results showed that the levels of creatine kinase (P = 0.001) and lactate dehydrogenase (P = 0.02), respectively, after two weeks of colostrum supplementation and acute resistance training were significantly different in the training group and supplementation compared to control group, but the amount of malondialdehyde in the exercise and supplement group did not show any significant difference in the three measurement steps compared to the control group (P = 0.09). <strong>Conclusion:</strong> It can be concluded that although resistance exercise increases muscle injury indices, but supplementation with colostrum may prevent it. <br />  <br />  <strong>Aim: </strong>Oral supplements are common among athletes to relieve muscle damage from exercise.
