The Opponent: the Female Athlete Triad
Some physically active women are at risk for a group of symptoms called the Female Athlete Triad. This often unrecognized disorder is a combination of three conditions:
Disordered eating, whether manifested as restrictive eating behaviors, bingeing, purging or excessive exercise, can lead to changes in normal body hormone (such as estrogen) function. Normal estrogen levels are needed to maintain calcium content in bone. Estrogen levels may be lowered when amenorrhea occurs and as a result calcium content can be lost from bone. The result is osteoporosis, or porous bones.
Who's at Risk: are all athletes on this team?
Any physically active woman is at risk for the Triad. The competitive nature and strong discipline that can help make a good athlete may also be part of the equation leading to this disorder. Competitive athletes may be at a higher risk than the more casual athlete due to a more rigorous training schedule and the "play-to-win" nature of their sports. Particularly at risk are participants in endurance sports, like cross-country running; aesthetic sports, like gymnastics or ballet; and sports which require form-fitting uniforms, like swimming or cheerleading. The emphasis on a certain "look" and the perception that carrying less weight will universally improve performance lead to this risk.
What's the Score: How will the Triad affect my performance?
Each part of the Triad can impair health and sport performance.
Disordered eating: an underfueled athlete is a slowed and weakened athlete. No matter what the sport, if muscles lack sufficient and proper fuel, performance is impaired. At first there might just be some early fatigue. As the fuel deficit worsens, actual loss of strength and muscle size can occur as the body catabolizes skeletal muscle in order to fuel essential body functions, like heart function and breathing. Lack of fuel can also lead to inability to concentrate, not a quality befitting an athlete. Athletes with strength losses and poor concentration can be more easily injured. Injuries then are slow to heal in a poorly fueled body.
Amenorrhea: Loss of menstrual periods may signal a change in the body's intricate and complicated hormone system. Hormone imbalance from underfueling your body can result in lowered estrogen production. There are also other causes of lowered estrogen levels. A diminished estrogen level can have many effects; the most immediately apparent one can be bone loss. Amenorrhea can often go unreported to health providers because of the common belief it is "just part of the training effect". We do know that the bone loss that occurs as a result of this is NOT "just part of the training effect" and can start to occur after just a few months with no period.
Osteoporosis: Loss of bone, especially in an athlete, can be an unfortunate set-up for an injury. Stress fractures can sideline sports activity and be slow to repair if an athlete is underfueled. Repeated stress fractures and unexplained injuries should be a red flag to further evaluate an athlete's eating and exercise patterns. Bone loss that occurs because of the amenorrhea of the Female Athlete Triad can be permanent; osteoporosis is not just a disease grandmothers get!
Scouting: Be on the Look Out for Signals that Help is Needed
In addition to the clinical information presented in the "Information Center", the following could be red flags warning a further look:
Making the Right Moves: How is the Triad Treated?
If you think you are have some of the symptoms of the triad OR are concerned about a friend or roommate, on-campus confidential resources are available for help. You may also want to discuss any concerns that you may have over any of the symptoms with your healthcare provider. Statistics tell us that when an athlete has any one of these Triad symptoms, she may be at increased risk for the other two.
