The aim of this study is to examine the beneficial effects of Danggui Buxue Tang on blood biochemical parameters in male recreational runners.
1. Male recreational runners would be recruited by community websites or email. After completely introducing the study, the participants would be requested to sign informed consent. 2. The participants would perform maximal oxygen consumption test prior to the supplementation. The participants would be supplemented with either Danggui Buxue Tang or placebo for a week before performing the 13-km run. A total of 4 times blood collection (before supplementation, immediate after running, 1 day and 3 days after running) would be performed for evaluating the effect of Danggui Buxue Tang on blood biochemical parameters.
