The Female Athlete Triad was examined in sedentary (SedOvul; n=10) and exercising (ExOvul; n=10) ovulatory women, and women with severe (ExOligo/Amen; n=19), or subtle (ExLPD/Anov; n=13) exercise-associated menstrual disturbances (EAMD). Resting metabolism (RMR/kg LBM) was lower in EAMD versus SedOvul (p=0.005), with the magnitude of severity dependent on EAMD. Bone mineral density (BMD) was lower in ExOligo/Amen versus ExOvul and ExLPD/Anov (p=0.052). Bone resorption was higher (p=0.030) in the Osteopenia group. Drive for thinness (DFT) scores were dependent on menstrual status (p=0.055). High DFT group (HDFT) had lower RMR/kg LBM than Normal DFT group (NDFT; p<0.027). Total 3,3',5-triiodothyronine was lower (p=0.018) in HDFT group, and related to (p=0.020) DFT. Bone formation was lower (p=0.019) in High Cognitive Restraint (CR) group versus Normal CR. CR was higher (p<0.001) in HDFT, and related to (p<0.001) DFT, indicating that DFT is a good screening tool to identify athletes at risk of developing the Triad.
