Recent research suggests that ingesting antioxidants during training may reduce exercise induced muscle soreness (EIMD), therefore the purpose of this study is to examine the effect of antioxidant supplementation on the performance related symptoms of EIMD in female participants. Methods: Participants were 10 non-resistance trained females, 21.6 ± 2.8 years. Subjects underwent 12 days of supplementation with an antioxidant capsule and 12 days of supplementation with a placebo capsule. To induce muscle damage, subjects performed an eccentric leg press protocol followed by measurements for range of motion (ROM), resting blood lactate, 5-RM testing, Wingate power output testing, and perceived muscle soreness. Assessments occurred prior to supplementation, immediately after exercise protocol, 48 and 96 hours post-exercise. Results: There were no significant changes in ROM, resting blood lactate, muscular strength, power output, or perceived muscle soreness between trials over the 96 hours following the exercise protocol. Conclusion: Antioxidant supplementation appears to have no effect on the performance related symptoms of EIMD in female participants.
