摘要

在耐力和超耐力运动员中,供能不足、饮食紊乱(DE)、运动依赖(EXD)以及相对于能量摄入的高训练需求可能会增加低能量可用性(LEA)的风险。本研究的目的是评估耐力跑运动员在训练和比赛期间出现低能量可用性(LEA)风险的普遍程度,以及与低能量可用性(LEA)风险、运动依赖性(EXD)和加油习惯之间的关系。年龄在 18-40 岁之间的越野跑者(n = 1,899;男性:n = 510,女性:n = 1,445)使用 Qualtrics 完成了一项包含 45 个问题的调查,调查内容包括训练和比赛特征、训练和比赛期间碳水化合物摄入问题、女性低能量可用性问卷(LEAF-Q)、运动员饮食紊乱筛查(DESA-6)和运动依赖量表-21(EDS-21)。在所有跑步者中,43% 的人有 LEA 风险,43% 的人有 DE 风险,87.3% 的人有 EXD 相关症状。LEAF-Q 评分与 EDS-21 评分(r = 0.33,p < 0.001)和 DESA-6 评分(r = 0.29,p < 0.001)呈正相关。在人群中,47.6%的运动员表示,在持续时间超过2.5小时的耐力比赛中,碳水化合物摄入量低于推荐标准。在女性运动员中,与没有 LEA 风险的运动员相比,有 LEA 风险的运动员似乎不太可能摄入充足的燃料(p < 0.001)。耐力跑运动员发生 LEA、DE 和 EXD 的风险似乎很高。此外,应强调在训练和比赛期间满足碳水化合物建议,以避免耐力跑运动员出现与 LEA 相关的不良健康后果。

Low Energy Availability, Disordered Eating, Exercise Dependence, and Fueling Strategies in Trail Runners.

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.
