ExOv, exercising ovulatory; ExIncon, exercising inconsistent menstrual cycles; ExAnov, exercising anovulatory; ExOligo, exercising oligomenorrhea; ExAmen, exercising amenorrhea; ExEumen, exercising eumenorrhea, includes ExOv, ExIncon and ExAnov; EEE, exercise energy expenditure; EA, energy availability.
  3. *, p-value associated with ANOVA performed to examine mean differences between ExOv, ExIncon, ExAnov, ExOligo and ExAmen groups.
  4. **, p-value associated with independent T-tests performed to examine mean differences between ExAmen and ExEumen groups.
