Abstract：
Problematic low energy availability (LEA) is the underlying cause of relative energy deficiency in sport (REDs). Male specific etiology, as well as the duration and degree of LEA exposures resulting in REDs remain to be adequately described. The present study aimed to assess occurrences of LEA (energy availability [EA] <25 kcal/kg fat-free mass/day) in male athletes from various sports over 7 days. Associations between number of LEA days, physiological measures, and body image concerns were subsequently evaluated. The athletes recorded their weighed food intakes and training via photo-assisted mobile application. Body composition and resting metabolic rates were measured, and venous blood samples collected for assessments of hormonal and nutrition status. Participants also answered the Low Energy Availability in Males Questionnaire (LEAM-Q), Eating Disorder Examination-Questionnaire Short (EDE-QS), Exercise Addiction Inventory (EAI), and Muscle Dysmorphic Disorder Inventory (MDDI). Of 19 participants, 13 had 0-2, 6 had 3-5, and none had 6-7 LEA days. No associations were found between the number of LEA days with the physiological and body image outcomes, although those with greatest number of LEA days had highest EEE but relatively low dietary intakes. In conclusion, this group displayed considerable day-to-day EA fluctuations but no indication of problematic LEA.
摘要：
有问题的低能量可用性（LEA）是运动中相对能量不足（REDs）的根本原因。男性特异性病因，以及导致RED的LEA暴露的持续时间和程度仍有待充分描述。本研究旨在评估7天内来自各种运动的男性运动员的LEA（能量可用性[EA]<25kcal/kg无脂质量/天）的发生情况。LEA天数之间的关联，生理措施，随后评估了身体形象问题。运动员通过照片辅助移动应用程序记录他们称重的食物摄入量和训练。测量身体成分和静息代谢率，和收集静脉血样本以评估荷尔蒙和营养状况。参与者还回答了男性低能量可用性问卷(LEAM-Q)，饮食失调检查-问卷简短(EDE-QS)，运动成瘾量表(EAI)，和肌肉畸形障碍量表(MDDI)。在19名参与者中，13有0-2，6有3-5，没有一个有6-7个LEA天。LEA天数与生理和身体图像结果之间没有发现关联，尽管LEA天数最多的人的EEE最高，但饮食摄入量相对较低。总之,该组显示出相当大的日常EA波动,但没有出现有问题的LEA.
