Summary

Dr Elliott-Sale is an associate professor in female physiology at Nottingham Trent University.

Dr Elliott-Sale teaches mainly in the areas of Exercise Physiology and particularly in Female Physiology, Performance, and Health.

In This Episode We Discuss:
--> Menstrual disorders: secondary amenorrhea (loss of 3 or more consectively) vs. oligomenorrhea (cycle longer than 45 days), vs.Functional --> Hypothalamic Amenorrhea (FHA) vs milder symptoms of some dysfunction
--> What is happening on a hormonal level that ties in with menstrual issues?
--> Understanding “energy availability”
--> How do we quantify what is “low” energy availability?
--> Relative Energy Deficiency in Sport VS. Female Athlete Triad
--> Landmark papers that really advanced understanding of this concept
Triad can lead to decreased estrogen. --> Implications for contraceptive pill users?
--> Difference in risk between genders? --> Difference in expression of symptoms among genders?
--> Reduced EA = increased illness/injury and thus more opportunities to train are lost.
--> Recommendations for at risk athletes
--> The screening and diagnosis of RED-S is challenging, as symptomatology can be subtle.
--> Individuality: How great the energy deficiency needs to be for that individual to be symptomatic

0:14.0	And, you know, that energy is low.
0:17.0	For females, it's really simple because, you know, regardless of what you call it or how you measure it or anything like that
0:22.6	If it occurs the mental cycle becomes blunted okay, so this is that secondary amenorrhea I was talking about and in that case all that sort of cyclical hormonal release is blunted and what we have is a flat line pretty much of estrogen and progesterone
0:38.3	so they won't have their periods okay and if they're non-hormonal contraceptive users and they don't
0:43.3	have their periods that's a really quick indicator of low energy availability Hello and welcome to Sigma Nutrition Radio.
