Methods: Eight young active participants were recruited from the Department of Physical Education at some universities in Busan City, Republic of Korea. The test period was divided into two Sections: non-supplemented period and supplemented period. Vo2 max and exercise performance time of participants were measured, with or without blueberry supplementation, with a portable gas analyzer and ECG, respectively. Results: Vo2 max and exercise performance time were increased in the blueberry supplementation period. IL-6 and CRP levels were significantly lowered in blueberry supplementation period following exercise. Conclusion: The blueberry supplementation can potentially increase the exercise performance and decrease the IL-6 and CRP levels caused by an increased TAS level.   https://ijph.tums.ac.ir/index.php/ijph/article/view/13668 https://ijph.tums.ac.ir/index.php/ijph/article/download/13668/6063
