AI Article Synopsis

  • Low energy availability (LEA) is a significant issue for athletes, potentially causing various health and performance problems, yet diagnosis can be tricky due to the body's ability to adapt over time.* -
  • The review outlines two phases of LEA: the initial phase where adaptation starts and the subsequent phase where adaptation is stabilized.* -
  • It emphasizes the need for better diagnostic approaches, highlighting biomarkers for each phase and suggesting future research on the link between red blood cell turnover and LEA.*

Article Abstract

Low energy availability (LEA) is a growing concern that can lead to several problems for athletes. However, adaptation to LEA occurs to maintain balance over time, making diagnosis difficult. In this review, we categorize LEA into two phases: the initial phase leading to adaptation and the phase in which adaptation is achieved and maintained. We review the influence of LEA on sports performance and health and discuss biomarkers for diagnosing LEA in each phase. This review also proposes future research topics for diagnosing LEA, with an emphasis on the recently discovered association between red blood cell turnover and LEA.
