Whether you are a competitive athlete, recreational exerciser, or performing at the elite level, you need to ensure you are consuming enough and the right types of energy to support your health and performance. However, in more recent years, it is becoming increasingly common for individuals to consume inadequate energy to support all of their requirements. In this article we learn about a term called energy availability, what can happen when you develop low energy availability and the health implications that can occur from a condition termed Relative Energy Deficiency in Sport. What is energy availability? Energy availability refers to the amount of energy left over and available for optimum function of bodily systems after accounting for the energy expended from exercise. EA = energy intake - energy expended from exercise So, what is low energy availability (LEA) Low energy availability occurs when dietary intake is insufficient to support energy expended from exercise and normal physiological functioning to support optimal health and performance. Prolonged or repeated acute bouts of LEA leads to a condition termed Relative Energy Deficiency in Sport, associated with negative health and performance implications. Relative energy deficiency in sport Relative energy deficiency in sport is a syndrome, caused by prolonged or repeated acute bouts of LEA. It can impact male and females and leads to negative health and performance implications. The detrimental outcomes can impact energy metabolism, reproductive function, musculoskeletal health, immunity, cardiovascular and haematological health, bone health, which synergistically impair wellbeing, performance and increase injury risk. How can you spot the warning signs of REDs Being on the lookout for signs and symptoms can lead to better identification and early intervention. Some things to look out for include:
If you suspect REDs, it is important to consult a sports dietitian and a sports physician for a proper diagnosis and treatment. Do not try to self-diagnose. Practical tips to maintain optimal energy availability.
