Female athlete triad: nutrition, exercise and health
Exercise and sports are widely known for their numerous health benefits. However, when physical activity is performed without proper guidance, particularly when high athletic performance is expected, it can also have negative effects on health.
The Female Athlete Triad is a condition of concern to healthcare professionals, particularly among women who engage in intense physical activity. It is characterized by three interconnected components:
-
Low energy availability (inadequate nutritional intake, with or without disordered eating)
-
Menstrual dysfunction (irregular or absent menstrual periods)
-
Low bone mineral density (which may lead to osteoporosis)
It is important to emphasize that exercise alone does not put someone at risk of developing the Female Athlete Triad. However, when energy intake is insufficient to meet the body’s energy demands, physical activity can become a contributing risk factor.
Athletic amenorrhea can occur in young women and girls who participate in sports that emphasize a lean physique. A girl striving for athletic success may adopt an excessively restrictive and unhealthy diet, depriving her body of essential nutrients while simultaneously increasing the frequency and duration of her training sessions.
This unhealthy approach can lead to disordered eating, menstrual irregularities or amenorrhea, and impaired bone development.
Which Athletes Are Most at Risk?
Although the Female Athlete Triad can affect athletes across different sports, women and girls who participate in activities that emphasize low body fat and low body weight may be at greater risk.
These activities and sports include:
-
Rhythmic and artistic gymnastics
-
Ballet
-
Diving
-
Figure skating
-
Aerobics
-
Running
Health Consequences
An unbalanced diet combined with menstrual dysfunction can negatively affect overall health. Potential consequences include:
-
Reduced athletic performance
-
Nutritional deficiencies
-
Low bone mineral density and osteoporosis
-
Gastrointestinal disturbances
-
Fertility problems
-
Stress fractures and other bone injuries
Prevention and Management
The primary goal is to restore adequate energy availability through a balanced diet that meets the body’s nutritional and physical demands, supporting normal menstrual function and bone health.
Reducing the frequency or intensity of exercise when necessary, alongside improving nutritional intake, can help restore a regular menstrual cycle and prevent further bone loss.
Early recognition and appropriate support from healthcare professionals, including a registered dietitian and physician, are essential for protecting long-term health and athletic performance.
