Low-energy availability in athletes is primarily associated with an increased risk of injury. When athletes consume insufficient energy relative to the demands of their training and activities, it can lead to various physiological complications. This energy deficit may result in a lack of essential nutrients that are critical for maintaining optimal body function, including muscle repair and bone health.

Inadequate energy intake compromises the body’s ability to recover from strenuous workouts, thus increasing fatigue and the likelihood of overuse injuries. More importantly, it can lead to hormonal imbalances, such as disruptions in the menstrual cycle for female athletes, which further heightens the risk of osteoporosis and stress fractures.

The other choices do not accurately reflect the implications of low-energy availability. Enhanced performance is unlikely when energy is lacking, as athletes need sufficient fuel to attain peak performance. Improved recovery cannot occur without adequate energy and nutrients to repair tissues and restore glycogen levels. While some athletes might experience a decrease in body fat due to low energy intake, this is not a primary consequence and can often be detrimental to overall health and performance in the long term. Thus, the most direct and significant consequence of low-energy availability is an increased risk of injury.
