- The purposes of this investigation were to determine if the free testosterone to cortisol ratio (fTC) is a reliable marker that can be used to monitor an athlete's training and possibly diagnose overtraining and/or the Overtraining Syndrome. The investigator also wanted to see if a 3-day intense micro-cycle of training causes an athlete to become overtrained. Twelve highly trained male endurance athletes cycled for 60 minutes at 75% of their VO2peak for 3 consecutive days. Blood samples were taken immediately pre and post-exercise and were analyzed for free testosterone and cortisol from which the fTC ratio was calculated. Results of this investigation suggest that the fTC ratio is a reliable marker as it did not significantly change during the training. Similarly, the results also suggest that 3 days of intense training may not be enough to cause an athlete to become overtrained.
