Both the quantity and quality of carbohydrates consumed significantly influence athletes' performance by improving muscle glycogen stores. This study aimed to evaluate the association of carbohydrate quality on enjoyment of physical activity and burnout in athletes.
The study included 139 active athletes aged 19-35 years. A Demographic Structure Questionnaire, Athlete Burnout Questionnaire, and Physical Activity Enjoyment Scale were administered to the participants. To assess carbohydrate quality, food frequency data were collected, and carbohydrate quality was scored based on fibre intake, the whole/total grain ratio, glycaemic index, and solid/total carbohydrate ratio. The score obtained was divided into 5 quartiles, with Q5 representing the highest and Q1 the lowest carbohydrate quality. Data were analyzed using SPSS 24 software.
Of the athletes, 76 were volleyball players, 36 were football players, and 27 participated in other sports. The age of the participants in the Q2 group was lower than in the Q4 group. The highest carbohydrate and protein intake was observed in the Q5 group, and the lowest in the Q1 group. The Physical Activity Enjoyment Scale score of the athletes in the Q5 group was significantly higher than that of the Q1 group (p < 0.05). There was a negative correlation between the Carbohydrate Quality Index and Athlete Burnout Questionnaire scores, glycaemic index, carbohydrate intake from liquids and refined grains, and a positive correlation between the Physical Activity Enjoyment Scale, carbohydrate intake from solids, and whole grains (p < 0.05).
Higher carbohydrate quality is positively associated with increased physical activity enjoyment and reduced burnout in athletes; however, further studies are needed on this topic.
通过增加肌肉糖原储备，所摄入碳水化合物的数量和质量均会显著影响运动员的表现。本研究旨在评估碳水化合物质量与运动员身体活动乐趣及倦怠之间的关联。
该研究纳入了139名年龄在19至35岁之间的现役运动员。向参与者发放了人口结构问卷、运动员倦怠问卷和身体活动乐趣量表。为评估碳水化合物质量，收集了食物频率数据，并根据纤维摄入量、全谷物/总谷物比例、血糖生成指数和固体/总碳水化合物比例对碳水化合物质量进行评分。所得分数被分为5个四分位数，Q5代表碳水化合物质量最高，Q1代表最低。使用SPSS 24软件对数据进行分析。
在这些运动员中，76人是排球运动员，36人是足球运动员，27人参加其他运动。Q2组参与者的年龄低于Q4组。Q5组的碳水化合物和蛋白质摄入量最高，Q1组最低。Q5组运动员的身体活动乐趣量表得分显著高于Q1组（p < 0.05）。碳水化合物质量指数与运动员倦怠问卷得分、血糖生成指数、液体和精制谷物中的碳水化合物摄入量呈负相关，与身体活动乐趣量表、固体和全谷物中的碳水化合物摄入量呈正相关（p < 0.05）。
较高的碳水化合物质量与运动员身体活动乐趣增加和倦怠减少呈正相关；然而，关于该主题还需要进一步研究。
