Treatment and study plan

Evaluation of menstrual function

Other

Evaluation of serum estradiol levels and menstrual history characteristics between sprinters, long marathon runners and non-athletes.

Primary outcomes

  1. serum estradiol level

    Time frame: 3 months

    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.

  2. Menstrual history characteristics

    Time frame: 3 months

    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. Age of participation to sport

    Time frame: 3 months

    It was taken in years from each female athlete through a self-administered questionnaire.

  4. Weekly training workload

    Time frame: 3 months

    It was taken in hours per week from each female athlete through a self-administered questionnaire.
