Organized electronic-sport competitions (e-Sport) is related to several health problems, including sleep disorders. The objective of this study was to evaluate the characteristics of the sleep-wake cycle of League of Legends (LoL) athletes during their pre-training, training, pre-competition, and competition routines. Twenty male elite LoL players completed the questionnaires related to sleep pattern (Pittsburgh Sleep Quality Index), sleepiness (Epworth Sleepiness Scale), and chronotype (Morningness-Eveningness Questionnaire), and they wore an actigraph for 7 days. Pre-training and pre-competition assessments were carried out by questionnaires (n = 20) and training and competition assessments by actigraph (n = 16). The chronotype that most Eathletes presented was a moderately evening type. They presented a poor sleep quality and were borderline for excessive daytime sleepiness. Sleep onset and offset times were significantly prolonged during the competition condition (t = 2.11, < .05; t = 2.51, < .05). Correlations showed a relationship between PSQI and Sleepiness in the pre-training and pre-competition conditions (r = 0.50, = .02) and chronotype with sleep onset (r = 0.61, = .01), total sleep time (r = 0.55, = .02), and time awake (r = 0.49, = .04) in the competition condition. Linear regression analysis indicated associations between the PSQI and sleepiness (25%; = .02) during pre-training and pre-competition. During the competition there were associations between chronotype and sleep onset (37%; = .01), chronotype and time awake (24%; = .04), and chronotype and TST (30%; = .02). In general, the findings support the conclusion that LoL athletes presented an altered sleep pattern during their training routines.
有组织的电子竞技比赛（电子竞技）与多种健康问题有关，包括睡眠障碍。本研究的目的是评估《英雄联盟》（LoL）运动员在赛前训练、训练、赛前和比赛常规中的睡眠-觉醒周期特征。20 名男性精英 LoL 运动员完成了与睡眠模式（匹兹堡睡眠质量指数）、嗜睡（Epworth 嗜睡量表）和昼夜节律（Morningness-Eveningness Questionnaire）相关的问卷，他们佩戴了 7 天的活动记录仪。赛前和赛前评估通过问卷进行（n=20），训练和比赛评估通过活动记录仪进行（n=16）。大多数运动员的昼夜节律类型是中度晚型。他们的睡眠质量较差，有日间嗜睡倾向。在比赛条件下，入睡和起床时间明显延长（t=2.11，<0.05；t=2.51，<0.05）。相关性显示，在赛前和赛前条件下，PSQI 与嗜睡（r=0.50，p=0.02）以及昼夜节律与入睡（r=0.61，p=0.01）、总睡眠时间（r=0.55，p=0.02）和觉醒时间（r=0.49，p=0.04）相关。线性回归分析表明，在赛前和赛前阶段，PSQI 和嗜睡之间存在关联（25%；p=0.02）。在比赛中，昼夜节律与入睡（37%；p=0.01）、昼夜节律与觉醒时间（24%；p=0.04）和昼夜节律与 TST（30%；p=0.02）之间存在关联。总的来说，这些发现支持了 LoL 运动员在训练常规中睡眠模式发生改变的结论。
