ABSTRACT
Under fueling, disordered eating (DE), exercise dependence (EXD), and high training demands relative to energy intake may increase the risk of low energy availability (LEA) in endurance and ultra-endurance athletes. The purpose of this study was to evaluate the prevalence of LEA risk and relationship with risk of DE, EXD, and fueling habits during training and competition in endurance runners. Trail runners between the age of 18-40 (n = 1,899; males n = 510, females n = 1,445) completed a 45-question survey using Qualtrics that included training and racing characteristics, questions regarding carbohydrate intake during training and competition, the Low Energy Availability in Females Questionnaire (LEAF-Q), the Disordered Eating Screen for Athletes (DESA-6), and the Exercise Dependence Scale-21 (EDS-21). Among all runners, 43% of runners were at risk for LEA, 43% were at risk for DE, and 87.3% reported symptoms related to EXD. LEAF-Q scores were positively correlated with EDS-21 (r = 0.33, p < 0.001) and DESA-6 scores (r = 0.29, p < 0.001). From the population, 47.6% of athletes reported taking in less than the recommended carbohydrate guidelines during endurance events lasting > 2.5 hours. In females, athletes at risk for LEA appear less likely to fuel sufficiently than athletes not at risk for LEA (p < 0.001). Risk of LEA, DE, and EXD appears to be high in endurance runners. Furthermore, meeting carbohydrate recommendations during training and competition should be emphasized to avoid negative health outcomes associated with LEA in endurance runners.
