Final answer:
Meredith is at risk for the Female Athlete Triad, a syndrome involving energy deficiency, menstrual disturbances, and decreased bone density due to her intense training for the Olympics.
Step-by-step explanation:
Meredith's Risk for the Female Athlete Triad
Meredith's dedication to competing in the Olympics and her intense training regimen of five or more hours daily on the track may put her at risk for a condition known as the Female Athlete Triad. This triad is a syndrome of three interrelated conditions that are often found in athletic females, particularly those in sports that emphasize leanness or endurance. The three components of the triad are: energy deficiency with or without disordered eating, menstrual disturbances/amenorrhea, and decreased bone mineral density/osteoporosis.
Energy deficiency occurs when an athlete consumes too few calories to support the level of energy expenditure required by their sport. This deficiency can be exacerbated by the pressure to maintain a certain body weight or physique, leading to disordered eating behaviors. Menstrual disturbances may result from the energy deficiency, affecting the athlete's hormonal balance and reproductive system. Decreased bone mineral density is a particularly concerning consequence, as it can lead to an increased risk of fractures and osteoporosis later in life.
It is critical that athletes like Meredith receive appropriate guidance and support from their coaches and health professionals to prevent these conditions through proper nutrition, monitoring menstrual health, and managing training load. By doing so, they can maintain their health while pursuing their athletic goals.
