Many endurance athletes have poor sleep quality which may affect performance and health. It is unclear how dietary intake affects sleep quality among athletes. We examined if sleep quality in endurance athletes is associated with consumption of fruit, vegetables, whole grains, dairy milk, and caffeinated beverages. Two hundred thirty-four endurance athletes (39.5 ± 14.1 year) participated in a survey. Participants provided information on demographics, anthropometry, sleep behavior and quality, and dietary intake questionnaires. Sleep quality was assessed using the Athlete Sleep Screening Questionnaire (ASSQ) with a global score (ASSQ-global) and subscales including sleep difficulty (ASSQ-SD), chronotype (ASSQ-C), and disordered breathing while sleeping (ASSQ-SDB). A general linear model (GLM), adjusted for age, body mass index, sleep discomfort, sleep behavior, gender, race, and ethnicity, showed that higher caffeinated beverage intake was related to poorer global sleep quality ( = 0.01) and increased risk for disordered breathing while sleeping ( = 0.03). Higher whole grain intake was associated with a morning chronotype and lower risk for sleep issues ( = 0.01). The GLM did not reveal a relationship between sleep quality and dairy milk, fruit, and vegetable intake. In conclusion, caffeinated beverages and whole grain intake may influence sleep quality. This relationship needs to be confirmed by further research.
许多耐力运动员睡眠质量较差，这可能会影响运动表现和健康。目前尚不清楚饮食摄入如何影响运动员的睡眠质量。我们研究了耐力运动员的睡眠质量是否与水果、蔬菜、全谷物、牛奶和含咖啡因饮料的摄入量有关。234名耐力运动员（39.5±14.1岁）参与了一项调查。参与者提供了有关人口统计学、人体测量学、睡眠行为和质量以及饮食摄入问卷的信息。使用运动员睡眠筛查问卷（ASSQ）评估睡眠质量，该问卷有一个总体评分（ASSQ-global）以及包括睡眠困难（ASSQ-SD）、生物钟类型（ASSQ-C）和睡眠时呼吸紊乱（ASSQ-SDB）的子量表。一个经过年龄、体重指数、睡眠不适、睡眠行为、性别、种族和民族调整的一般线性模型（GLM）显示，较高的含咖啡因饮料摄入量与较差的总体睡眠质量（P = 0.01）以及睡眠时呼吸紊乱风险增加（P = 0.03）有关。较高的全谷物摄入量与早晨生物钟类型以及较低的睡眠问题风险相关（P = 0.01）。GLM未揭示睡眠质量与牛奶、水果和蔬菜摄入量之间的关系。总之，含咖啡因饮料和全谷物摄入量可能会影响睡眠质量。这种关系需要进一步研究来证实。
