title: Verification of efficacy as an ergogenic aid and safety in doping of sibjeondaebo-tang.
abstract: OBJECTIVE
  Various kinds of food substances from all over the world have been proposed to use as ergogenic aids for the additional improvement of exercise performance especially in athletes. Herb medicine which usually being applied for the cure of disease is used as a performance booster in several far eastern countries including Korea. Many scientists and coaches have asked very objective verifications on the reality of herb medicines practically used but never been scientifically elucidated well enough. In addition to the possibility as an ergogenic aid, the safety in doping is the critical factor to be examined thoroughly. In this study, Sibjeondaebo-Tang, a leading popular prescribed herb medicine in Korea, was examined.
  
  
  METHODS
  After the intake of Sibjeondaebo-Tang, its effects on VO2max, recovery from fatigue, and doping safety through the official process as WADA suggested. Six volunteered male Taekwondo Pumsae players were subjected in a repeatedly examined protocol.
  
  
  RESULTS
  First of all, every subjects showed 'negative' in doping test, and the treatment did not show any significant improvement on VO2max even though there was a significant decrease in blood lactate level on a step test.
  
  
  CONCLUSIONS
  In conclusion, Sibjeondaebo-Tang may have some limited effects as a fatigue delayer and the use of it showed safe to doping test with the strict limitation as the way in this study. So we should abstain from the over-interpreted application of the results so far.
