The Concept of Low Energy Availability

Low energy availability refers to the deficit between energy intake and energy expenditure. It takes into account not only the energy spent on exercise but also the energy expended on basic bodily functions like digestion and metabolism. This state can have significant repercussions on an athlete's health and performance, affecting various aspects such as menstrual function, bone health, metabolism, cardiovascular function, gastrointestinal system, mental health, and more. It is important for athletes to be aware of the signs and symptoms of low energy availability and to ensure that they are fueling their bodies adequately throughout the day.
