claim3 4 5 6 7 8 9 2 3 10 Recent epidemiological work indicates that LEA and clinical REDs affect a substantial minority of athletes; contemporary prevalence estimates in endurance and aesthetic disciplines commonly range from 20% to over 60%, with the highest risk reported in sports emphasising leanness or weight categories [,].

claimConverging evidence further indicates that even moderate, cumulative energy deficits can elicit measurable physiological perturbations.

claimA quantitative characterisation of how such loading, when coupled with inadequate energy intake, alters the composition and function of skeletal muscle, adipose, and bone tissue is therefore essential for evidence-based prevention and for optimising training adaptation.
