Female Triad 🔺 Flashcards
As the diet becomes more restrictive, energy availability is too low, mechanisms reduce the amount of ATP for cell function, thermoregulation, growth, and reproduction. THIS LEADS TO:
survival mode to conserve energy
but impairs health😷
What T-score would indicated “low bone mass”
1-2.5 SD below the mean
What is the normal energy availability from dietary intake
45 kcal/kg FFM/day
decreased levels of ovarian estrogen from amenorrhea can lead to
decreased bone mineral density
osteoporosis
what affect does chronic increased cortisol have on bones
increased resorption
WEAK ASS BONES
What is the threshold of energy availability from dietary intake where things begin to go wrong?
30 kcal/kg FFM/day
Oligomenorrhea is a period of ____ days or more between cycles
35
Amenorrhea is the absence of menstrual cycle lasting more than
90 days
Menstrual dysfunction can predict for future:
low BMD
At what energy availability from dietary intake do amplitudes of LH decrease but frequency does not change
30 kcal/kg FFM/day
Reducing energy intake is associated with ____ LH amplitude but _____ pulse frequency
⬆️increased LH amplitude
⬇️reduced pulse frequency
Increased risk in developing amenorrhea can lead to increased production of
ovarian estrogen
Does menstruation occur in anovulation?
Yes but no ovulation
impaired follicular development
What Z-score is considered below the expected range for age
2 SD below the mean
What causes the physiological disturbance in the endocrine control of the menstrual cycle
high training volume + low energy intake
