The aim of the study was to evaluate the activity of a standardized ex
tract of Ginseng (G115) on the physical condition of a group of 43 tri
athletes of a good standard, aged 24-36 years, during the sport season
. The study was of cross-over design and for two consecutive periods o
f 10 weeks. No significant conclusions could be drawn from the data co
llected during the first 10 weeks period. However, dur ng the second p
eriod the drug seemed to prevent the loss of physical performance char
acteristic of end of season tiredness. Thus, G115 could be a non-dopin
g <<adaptogen>>. The observation of a carry-over effect should temper
the overall conclusions, but should not prevent us from taking them in
to consideration.
