Track and field athletes have intense physiological demands and require optimized nutrition ( Burke et al., 2019 ; Slater et al., 2018 ; Stellingwerff et al., 2018 ; Sygo et al., 2019 ). Track and field athletes may experience low energy availability (LEA) due to disordered eating (DE) behavior

Low energy availability (LEA), defined as inadequate energy intake relative to exercise energy expenditure, is the underlying cause of relative energy deficiency in sport and manifests in a range of health and performance impairments. 1 Relative energy deficiency in sport has predominantly been

undesirable consequences when an athlete aims for negative energy balance and weight reduction, which can lead to severely negative effects on health and performance. 5 Energy availability (EA) is defined as “ energy intake minus exercise energy expenditure ” and represents the amount of dietary energy

Low energy availability (LEA) is a state wherein dietary energy intake fails to support normal physiological functioning once the energy committed to exercise has been removed, and has been associated with negative health outcomes ( Loucks et al., 2011 ). Modest periods of LEA may be integral to

In 2014, the International Olympic Committee first used the term Relative Energy Deficiency in Sport (RED-S) to describe the lack of energy for performance and health in female and male athletes. The underlying premise of RED-S is low energy availability (LEA), whereby the amount of dietary energy

Energy availability (EA) refers to the amount of energy available for basic physiological processes, such as

systems, including, but not limited to, the endocrine, cardiovascular, immune, and gastrointestinal systems, as well as menstrual function and bone health. The underlying cause of RED-S is low energy availability (LEA), defined as the amount of energy relative to fat-free mass remaining for physiological

bioenergetics, energy availability (EA) is defined as energy that can be devoted to individual body systems. In sports nutrition, EA is more specifically defined as the residual energy available to support an athlete’s body functions, once the energy expenditure of exercise (EEE) is deducted from energy intake

Energy availability (EA) is a scientific concept describing how much energy is available for basic metabolic functions such as building bones and creating hormones when energy expended in exercise (exercise energy expenditure, EEE) has been subtracted from daily total energy intake (TEI; Loucks et

Energy availability (EA) is the difference between energy intake (EI) and exercise energy expenditure (EEE) in relation to fat-free mass (FFM) ( Loucks & Thuma, 2003 ). The threshold for clinical low EA (i.e., <30 kcal/kg FFM) was defined when Professor Anne Loucks and Professor Jean Thuma observed
