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.
