What does RED-S stand for?

Relative energy deficiency in sport, commonly referred to as RED-S, describes a condition arising when an athlete does not consume enough energy to support their training and daily activities. This can happen when there is an imbalance between energy intake and energy expenditure. It is particularly relevant in sports where maintaining a certain body weight or performance level is emphasized.

RED-S can lead to a multitude of health consequences, including hormonal imbalances, diminished athletic performance, increased risk of injuries, and various psychological issues. Understanding this term is crucial for athletes, coaches, and healthcare providers, as it highlights the need for adequate nutrition to support both physical performance and overall health.

The other options refer to concepts that do not accurately capture the essence of RED-S. Recreational energy deficiency in sports and regular exercise deficiency in sport are not recognized terms in the context of energy balance and health. Similarly, rapid energy depletion in sports focuses too narrowly on the short-term aspect of energy consumption during activities, rather than the longer-term implications of energy availability, which is central to the concept of RED-S.
