Which of the following is NOT a component of the female athlete triad?

The female athlete triad is a condition observed in physically active females, characterized by three interrelated components: eating disorders, amenorrhea, and low bone mineral density or osteoporosis.

Menstrual cycle regularity, listed as the answer, is not a component of the triad; in fact, disruptions in menstrual cycle regularity are indicative of issues related to the triad. When energy intake is insufficient to meet the energy expenditure of athletes, it can lead to amenorrhea, which is the absence of menstruation. This absence is symptomatic of underlying health challenges, such as disordered eating and decreased bone density, and highlights the interconnectedness of these components.

The other options represent the actual components of the female athlete triad: eating disorders encompass a range of unhealthy eating habits; osteoporosis refers to the decrease in bone density that can occur due to the combination of low energy availability and hormonal disruptions; and amenorrhea itself is a significant marker of this condition. Understanding these components is crucial for recognizing and addressing the health and performance implications for female athletes.
