Background : The purpose of this study was to examine that the effects of Peony-Licorice (PL) mixture supplementation on post-exercise blood glucose and lactate in professional women basketball players. Methods: Eleven professional women basketball players were participated in this study. The subjects participated in two trials, PL supplementation and water supplementation. They did 20-meter shuttle run test, and measured blood glucose and lactate level before, immediately, after 3 minutes, after 5 minutes and after 10 minutes the test. Results: There was not interaction effect on blood glucose(p<0.433) and lactate(p<0.770) levels. Blood glucose and lactate levels were increased in PL group and water group after the test. Conclusion: PL supplementation could not affect changing blood glucose and lactate level. Therefore, we suggest that PL supplementation may not be positive ergogenic aid for improving exercise performance in professional women basketball players.
