Excessive exercise, disordered attitudes toward eating, physical and psychological stress, and/or hormonal imbalances may result in cessation of menstruation (secondary amenorrhea). The accompanying lack of estrogen may impair muscle power and oxygen recovery after exercise by reducing nitric oxide levels. The purpose of this study is to determine whether ingestion of beetroot juice containing nitrate, an alternative source of nitric oxide, can help reverse these changes.
