What condition that affects young female athletes is associated with insufficient calcium intake and may hinder bone growth?

Insufficient calcium intake can significantly impact bone health, especially in young female athletes whose bodies are still in the growth phase. The correct answer highlights amenorrhea, which is the absence of menstrual periods. This condition is often seen in athletes due to energy deficits, excessive training, or low body fat, leading to hormonal changes that can affect bone density and growth.

When a young female athlete experiences amenorrhea, the disruption in menstrual cycles can lead to lower levels of estrogen, a hormone that plays a crucial role in bone maintenance and growth. Insufficient estrogen, coupled with low calcium intake, increases the risk of decreased bone density, potentially resulting in conditions like osteoporosis or osteopenia later in life. Therefore, the link between amenorrhea and insufficient calcium intake illustrates how vital nutrition is for overall health and proper development in young female athletes.
