Resting testosterone concentrations were determined in three female athletes preparing for European Championships in weight lifting. Capillary blood was sampled for 10 consecutive days twice: at the beginning of the training period (February) and before championships (May). Mean testosterone level was significantly (p < 0,001) higher in May than in February (2,78 and 2,03 nmol/L, respectively), the levels in consecutive days being alike. The athletes won positions II, III and IV, which may be suggestive of a relationship between the training-induced changes in testosterone concentrations and sport result.
