LEA describes a mismatch between an individual's dietary energy intake and the energy cost of their commitments for training and competition. The main questions this trial aims to answer are:\n\n1. What effect does short-term, severe LEA have on sleeping metabolic rate?\n2. What effect does short-term, severe LEA have on other body systems identified within the Relative Energy Deficiency in Sport (REDs) Health and Performance Conceptual models?\n\nResearchers will compare a control trial with both a LEA trial achieved through diet restriction and a LEA trial achieved through increased exercise to see if there are differences in the body's response.\n\nParticipants will complete three 6-day trials, a minimum of 3-weeks apart, involving:\n\n* Prescribed diet (all food provided)\n* Prescribed running and\u002For cycling exercise\n* Two visits to ACU Fitzroy campus for blood tests and exercise testing\n* 50 hour stay (two nights and two days) in the ACU metabolic chamber",[27],"Relative Energy Deficiency in Sport",[29,30,31,32,33],"Relative Energy Deficiency in Sport (REDs)","Endurance","Athlete","Sleeping Metabolic Rate","Problematic Low Energy Availability","RECRUITING","2025-06-10",{"date":37,"type":38},"2025-06-18","ACTUAL",{"date":40,"type":21},"2025-06",{"date":42,"type":21},"2027-06",{"name":44,"class":45},"Australian Catholic University","OTHER",""]
