Effects of two-weeks colostrum supplementation on muscle injury indices and lipid peroxidation following an acute resistance activity session in wrestlers

Oral supplements are common among athletes to relieve muscle damage from exercise. 30 wrestlers were selected voluntarily .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). 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. 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). It can be concluded that although resistance exercise increases muscle injury indices, but supplementation with colostrum may prevent it.
