We examined the impact of weightlifting training on the ratio of serum testosterone to cortisol (T:C) as athletes prepared for a competition. Eight male weightlifters (mass= 82.0 10.8kg, age= 20 1y) completed nine weeks of periodized training before competing in a USAW-sanctioned weightlifting meet. Fasting blood samples were obtained from subjects at four time points over the training period. The blood samples were analyzed for concentrations of testosterone and cortisol using an enzyme-linked immunosorbent assay. Training volume significantly decreased (p<.001) as athletes approached competition. Training intensity significantly increased (p= .01) before tapering for competition. The T:C ratio did not significantly change over time. The T:C ratio at the third measurement point (prior to training taper) was correlated to the volume of work competed during the taper week (r=.779). No other correlations were found. These data indicate that the T:C ratio is not a sensitive indicator of training status.
