title: Energy availability, not body fatness, regulates reproductive function in women.
abstract: The morbid consequences of menstrual disorders in athletes require medical diagnosis and treatment. Reproductive disruption appears to occur when energy availability (dietary energy intake minus exercise energy expenditure) falls below a threshold between 20 and 30 kcal x kgLBM(-1) x d(-1), and some women may be more severely affected than others by subthreshold energy availability.
