Assessing the Values of Blueberries Intake on Exercise Performance, TAS, and Inflammatory Factors

Background: The purpose of this study was to determine the effect of blueberry supplementation on exercise performance time, inflammation markers, energy substrates, insulin, and TAS levels during two periods: non-supplemented period and supplemented period. 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.
