Clark LR, Dellogono MJ, Mangano KM, Wilson TA. Clinical Menstrual Dysfunction Is Associated with Low Energy Availability but Not Dyslipidemia in Division I Female Endurance Runners. JEPonline 2018;21(2):265-276. The purpose of this study was to determine the prevalence of low energy availability (EA) and clinical menstrual dysfunction (MD) in collegiate female endurance runners, identify associated health and performance characteristics, and evaluate the LEAF-Q as a screening tool in this population. The subjects were female NCAA Division I Student-Athletes (N=15) participating in track and field events with a distance of 800 m to 10 K. EA was calculated using 3-d diet records, accelerometers, and heart rate monitors. Maximal oxygen uptake (V[O.sub.2] max) and resting energy expenditure were measured via indirect calorimetry. Forty percent of the athletes' reported current clinical MD (EA 28.7 [+ or -] 7.5 kcal*[kg.sup.-1]* FFM). Sixty percent of the athletes reported regular or subclinical menstrual status (EA 31.0 [+ or -] 7.6 kcal*[kg.sup.-1]*FFM). LEAF-Q effectively identified individuals with current or history of clinical MD at risk for low EA. There was no significant difference in blood lipids between athletes with clinical or subclinical MD. The EA threshold Key Words: Amenorrhea, Endurance, Energy Availability, Runners
INTRODUCTION Menstrual disturbances occur at much higher rates in physically active females than in their sedentary counterparts (2,33,40). Exercise-associated clinical menstrual dysfunction (MD) may be classified either as functional hypothalamic [...]
