Type	Measure	Description	Time frame	Safety issue
Primary	serum estradiol level	Blood samples were obtained on the 2nd day of the menstrual cycle at 10.00 a.m. following overnight fasting and rest. The athletic females were instructed to refrain from performing strenuous exercise on the day of sampling. Blood samples were separated and stored at -80°C till analysis of serum estradiol levels. Serum estradiol levels were measured to evaluate the menstrual function. The manufacturer indicated the following reference intervals for healthy females: Estradiol 40-350 pg/ml.	3 months
Primary	Menstrual history characteristics	The age at menarche (in years), the number of menstrual cycles in the past year, and the length of menstrual cycles (in days) were collected through a self-administered questionnaire to evaluate the menstrual status of each female participant.	3 months
Primary	Age of participation to sport	It was taken in years from each female athlete through a self-administered questionnaire.	3 months
Primary	Weekly training workload	It was taken in hours per week from each female athlete through a self-administered questionnaire.	3 months
