Relative energy deficiency in sport (RED-S) can negatively affect an athlete’s performance in many ways. For example, associated iron deficiency or iron deficiency anemia can decrease athletes’ aerobic work capacity. RED-S can also interfere with an athlete’s ability to consistently train and compete due to the increased risk of illness and injury.
