It refers to the potential health and performance consequences of inadequate energy for sport, emphasizing that there are consequences of low energy availability (EA; typically defined as &lt;30\u00a0kcal\u00b7kg<jats:sup>\u22121<\/jats:sup> fat-free mass\u00b7day<jats:sup>\u22121<\/jats:sup>) beyond the important and well-established female athlete triad, and that low EA affects populations other than women. As the prevalence and consequences of Relative Energy Deficiency in Sport become more apparent, it is important to understand the current knowledge of the hormonal changes that occur with decreased EA. This paper highlights endocrine changes that have been observed in female and male athletes with low EA. Where studies are not available in athletes, results of studies in low EA states, such as anorexia nervosa, are included. Dietary intake\/appetite-regulating hormones, insulin and other glucose-regulating hormones, growth hormone and insulin-like growth factor 1, thyroid hormones, cortisol, and gonadal hormones are all discussed. The effects of low EA on body composition, metabolic rate, and bone in female and male athletes are presented, and we identify future directions to address knowledge gaps specific to athletes.<\/jats:p>","DOI":"10.1123\/ijsnem.2018-0127","type":"journal-article","created":{"date-parts":[[2018,7,14]],"date-time":"2018-07-14T15:33:42Z","timestamp":1531582422000},"page":"335-349","source":"Crossref","is-referenced-by-count":199,"title":["Endocrine Effects of Relative Energy Deficiency in Sport"],"prefix":"10.1123","volume":"28","author":[{"given":"Kirsty J.","family":"Elliott-Sale","sequence":"first","affiliation":[{"name":"Nottingham Trent University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam S.","family":"Tenforde","sequence":"additional","affiliation":[{"name":"Spaulding Rehabilitation Hospital"},{"name":"Brigham and Women\u2019s Hospital"},{"name":"Harvard Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allyson L.","family":"Parziale","sequence":"additional","affiliation":[{"name":"Boston Children\u2019s Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bryan","family":"Holtzman","sequence":"additional","affiliation":[{"name":"Boston Children\u2019s Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathryn E.","family":"Ackerman","sequence":"additional","affiliation":[{"name":"Harvard Medical School"},{"name":"Boston Children\u2019s Hospital"},{"name":"Massachusetts General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"8","key":"r1","series-title":"Medicine & Science in Sports and Exercise,","first-page":"1577","article-title":"Fractures in relation to menstrual status and bone parameters in young athletes","volume":"47","author":"Ackerman, K.E.","year":"2015","unstructured":"Ackerman, K.E., Cano Sokoloff, N.G., De Nardo Maffazioli, G., Clarke, H.M., Lee, H., & Misra, M.
