    Physical Therapy Guide to Female Athlete Triad

    Female athlete triad (triad) is a syndrome that can manifest across a broad spectrum, but involves the interrelationship between 3 measurable factors: (1) how much energy a woman has available to use for activity (energy availability), (2) the quality and strength of her bones (bone mineral density), and (3) her menstrual cycle. Clinically, imbalances in any one of these areas can lead to eating problems, osteopenia/osteoporosis, and/or menstrual dysfunction. The prevalence of all 3 components of female athlete triad among high school, collegiate, and elite athletes in the United States can be as high as 16%; the prevalence of any one component of the triad in this population can be as high as 60%.

    Physical therapists can identify signs and symptoms of female athlete triad and initiate care as one member of your health care team when needed. 

    Physical therapists are movement experts who improve quality of life through hands-on care, patient education, and prescribed movement. You can contact a physical therapist directly for an evaluation. To locate a physical therapist in your area, visit Find a PT.

    What Is Female Athlete Triad?

    Female athlete triad is a syndrome that can involve both the physical and mental aspects of health. It develops in female athletes based on 3 factors: energy availability, bone mineral density, and the menstrual cycle.

    Energy availability is calculated by how much energy you gain from dietary sources, minus the amount of energy you expend during activity. Typically, with triad poor energy availability is the driving force behind abnormal bone density and menstrual dysfunction. Poor energy availability is caused by poor nutrition; it can occur with or without the presence of an eating disorder. Nutrients act to provide the necessary source of fuel for bones and muscles. Poor nutrition also can have a negative effect on the part of the brain that controls hormones that regulate the menstrual cycle. Optimal energy availability supports bone health specifically by maintaining estrogen levels. Estrogen is an important hormone that has a protective effect on bone by supporting the balance between bone building and bone loss. Therefore, lack of estrogen can impact bone density and may increase the risk of bone stress injuries.

    Bone mineral density (BMD) defines 1 aspect of bone health. When your bones are not supplied with necessary nutrients or are stressed too much through overexercising, they may begin to weaken. This weakening can lead to osteopenia (lower than normal BMD) and further, osteoporosis (a loss of bone strength that predisposes a person to increased risk of fractures). When a person has low BMD, she may be at an increased long-term risk of bone mineral loss and fracture as she ages.

    Menstrual dysfunction refers to abnormal menstrual periods. This spectrum can range from oligomenorrhea (inconsistent menstrual cycles) to amenorrhea (absence of a menstrual period) in females who are of a reproductive age.

    Female athletes are at an increased risk of developing triad due to the high demand that athletics place on the female body physically, as well as the increasing societal pressures for performance and image. For example, a female runner may feel that altering or restricting caloric intake will make her a faster runner, therefore gaining an edge on the competition and earning greater success in her sport. Triad can be present in any female athlete, from the elite athlete striving to reach high-performance goals, to the adolescent female whose body is going through normal changes related to puberty. In any case, there are physical and psychological aspects of this syndrome that affect its extent, impact, and treatment.

     

    How Does It Feel?

    Female athlete triad is not caused by a sudden traumatic injury; therefore, no immediate symptoms typically appear. Instead, symptoms related to the 3 components of triad may develop over time, ranging from months to years.

    A female athlete may begin experiencing the following symptoms, conditions, or changes (separately or together) that may indicate she is developing female athlete triad:

    • Low energy during school, work, or exercise
    • Irregular or absent menstrual cycles
    • Stress-related bone injuries (stress reactions or fractures)
    • Difficulty concentrating
    • An unexplained drop in performance
    • Changes in eating habits
    • Altered sleeping patterns
    • An unusually high focus on performance or image
    • Experiencing high levels of stress
     

    How Is It Diagnosed?

    A multidisciplinary team of medical providers typically diagnoses female athlete triad. The team may include medical doctors, nutritionists, physical therapists, certified athletic trainers, and psychologists. However, nonmedical individuals, such as parents, friends, coaches, teammates, teachers, and work colleagues can also be resources to help identify female athletes who demonstrate signs of triad, as these are all people who spend time with the athlete. Often, the athlete does not realize that she has low energy availability or any of the symptoms of triad; therefore, it often becomes the responsibility of a health care professional to educate a patient and her parents and coaches.

    If it is suspected that an athlete may be demonstrating 1 or more components of triad, a proper screening interview can help identify the components, including questions about menstrual status and history, history of stress or bone injury, and eating disorder tendencies. These questions may include:

    • Have you ever had a stress fracture?
    • Do you have menstrual periods?
    • Are you trying to or has anyone recommended that you gain or lose weight?
    • Are you on a special diet?
    • Have you ever been diagnosed with an eating disorder?

    To diagnose triad, a number of medical and psychological tests and consultations may be recommended, including:

    • Diagnostic imaging of bone health (ie, X-ray, bone density scan [DEXA])
    • Referral to a nutritionist for dietary assessment
    • Referral to a primary care or family medical doctor for monitoring of menstrual function or related medical tests (eg, blood tests, assessment of the natural stages of development, such as the onset of puberty)
    • Referral to a physical therapist for functional assessment (ie, motion, strength, movement quality)

    Because triad involves multiple components of health, an athlete who is able to receive care from all relevant health care practitioners has the best chance of developing a comprehensive plan to return to good health and athletic participation/performance.

     

    How Can a Physical Therapist Help?

    Physical therapists are trained to identify signs and symptoms of female athlete triad and initiate multidisciplinary care as appropriate and needed. The physical therapist can assist with prevention and the promotion of health, wellness, and fitness, in addition to providing rehabilitation following an injury. Primary prevention includes proper screening of any female athlete for triad, asking questions such as those stated above, and referring the athlete to other appropriate health care professionals.

    Physical therapists are also trained to understand the implications that triad may have on exercise prescription. For example, an athlete with a stress fracture due to low BMD should not perform jumping and running movements. Once an athlete's symptoms are resolved, her physical therapist can design an individualized return-to-activity program that encourages a safe, progressive level of activity. A physical therapist also can identify if an athlete is at an increased risk of overuse injury or abnormal loading of the bone or a joint.

    Physical therapists are trained to educate athletes and their families about triad, and work with athletes to prevent or resolve the condition—guiding them back to safe, optimal performance levels. In many cases, this attention to and care for a female athlete's overall health can improve her performance in athletics and in school as well, and boost her overall self-esteem. Many athletes report that they are more confident, stronger, and better equipped to achieve their goals when they feel they have strong support and a plan for sustained health.

     

    Can This Injury or Condition Be Prevented?

    The Female Athlete Triad is a very preventable condition.

    The most effective approach to prevention is education. As both the level of female participation in competitive sports and the incidence of the Triad have risen over the last 2 decades, a stronger emphasis has been put on educating athletes, parents, and coaches on strategies to prevent the development of causal factors for the Triad. It is important to begin educating young female athletes as early as middle-school age on topics such as healthy eating, smart physical training, recovery and rest, and taking care of their bodies.

    Coaches should monitor training and its impact on the overall health of the athlete by encouraging pain-free participation in sports; they may also track training and performance in order to notice any abnormal health or behavioral signs. Individuals involved in the life of a female athlete should promote an open, honest, and safe environment for the athlete so that she feels comfortable discussing challenges or issues she may be facing without the risk of external pressure or judgment.

     

    What Kind of Physical Therapist Do I Need?

    All physical therapists are prepared through education and experience to identify female athlete triad. However, you may want to consider:

    • A physical therapist who is experienced in working with people who have female athlete triad. Some physical therapists have a practice with an orthopedic or musculoskeletal focus.
    • A physical therapist who is a board-certified clinical specialist or who completed a residency or fellowship in orthopedic or sports physical therapy. This physical therapist has advanced knowledge, experience, and skills that may apply to your condition.

    You can find physical therapists who have these and other credentials by using Find a PT, the online tool built by the American Physical Therapy Association to help you search for physical therapists with specific clinical expertise in your geographic area.

    General tips when you're looking for a physical therapist (or any other health care provider):

    • Get recommendations from family and friends or from other health care providers.
    • When you contact a physical therapy clinic for an appointment, ask about the physical therapists' experience in helping people with female athlete triad.
    • During your first visit with the physical therapist, be prepared to describe your symptoms in as much detail as possible.
