Final answer:
Osteopenia and Osteoporosis relate to the 'Bone Health' category of the Female Athlete Triad, as they are conditions characterized by weakened bone structure and density.
Step-by-step explanation:
The categories Osteopenia and Osteoporosis specifically pertain to the category bone health within the context of the Female Athlete Triad. The Female Athlete Triad is a syndrome that affects physically active females and is characterized by three interrelated components: energy availability, menstrual function, and bone health. Osteoporosis and osteopenia are conditions where bones become weak and brittle, and they are directly related to bone health. These bone conditions are often linked to hormonal changes such as reduced estrogen levels, as well as inadequate calcium and vitamin D intake, critical for bone mass and density.
