Energy and nutrient status of amenorrheic athletes participating in a dietand exercise training intervention program

Chronic energy deficit is one of the strongest factors contributing to exer cise-induced menstrual dysfunction. In such cases, macro- and micronutrient intakes may also be low. This study presents the results of a diet and exe rcise training intervention program, designed to reverse athletic amenorrhe a, on improving energy balance and nutritional status in 4 amenorrheic athl etes. The 20-week program provided a daily sport nutrition supplement and 1 day of rest! week. The intervention improved self-reported energy intake ( ET) and balance in all participants. The program increased protein intakes for the 3 athletes with a protein deficit to within the recommended levels for active individuals. Micronutrient intakes increased, as did serum conce ntrations of vitamin B12, folate, zinc, iron, and ferritin. These results i ndicate that some amenorrheic athletes have poor nutritional status due to restricted EIs and poor food selections. A sport nutrition supplement may i mprove energy balance and nutritional status in active amenorrheic women.
