138. Low Energy Availability and Relative Energy Deficiency in Sport (RED-S) Updates: From the Lab to Practical Application

Monday, October 28
1:30 PM – 3:00 PM
Location: 115-ABC
CE: 1.5
Level 3- Advanced

Low energy availability (LEA) describes scenarios in which an athlete’s dietary intake is unable to meet the energy cost of their exercise commitments, as well as the body’s needs for health and optimal function. The resulting metabolic adjustments can impair reproductive function, bone health, optimal protein synthesis, cardiovascular health, training adaptation and performance; these outcomes are part of the manifestation of Relative Energy Deficiency in Sport (RED-S) syndrome. This presentation will summarize the causes of LEA, challenges of assessing its presence, and updates on strategies to prevent and treat RED-S.

Planned with the Committee for Lifelong Learning

Learning Objectives:

  • Identify the scenarios that typically lead to Low Energy Availability (LEA) in male and female athletes
  • Describe the challenges of assessing LEA in the field
  • Summarize the range of issues related to impaired health and performance that may arise from LEA (the Relative Energy Deficiency in Sport [RED-S] syndrome

Learning Need Codes:

  • 2110 Physiology, exercise physiology
  • 3010 Assessment methodology
  • 4060 Exercise, fitness, sports nutrition
