目标：描述 2014 年巴西 FIFA 世界杯之前向东长途跨子午线航空旅行对职业足球运动员主观时差、睡眠和健康的影响。设计：单一队列，涉及代表国家足球队的 22 名男性职业足球运动员。方法：从澳大利亚悉尼到巴西维多利亚国际旅行之前和之后收集球员的数据。总共有 3 个航班，向东飞行 19 小时、14,695 公里，跨越 11 个时区。在旅行之前和之后的一周内获取训练负荷和健康测量值，同时在旅行前一天（前）、到达当天和旅行后五天（后 1-5）收集睡眠和时差测量值。 结果：与前相比，后 1 至 4 时感觉到的时差显着增加，后 1 的时差水平明显高于后 5（p < 0.05）。旅行期间自我报告的睡眠持续时间为 5.9 (4.8-7.0) 小时，显着低于所有其他夜晚 (p < 0.01)，但抵达当晚除外，与 1-4 后相比，在床时间和睡眠持续时间显着减少 (p < 0.01)。最后，与旅行前一周相比，旅行后一周的平均健康状况显着下降（p < 0.01）。结论：自我报告的向东长途跨子午航空旅行期间和之后的睡眠中断，以及加剧的时差症状可能会导致玩家健康状况下降。因此，尽管缺乏身体表现数据，但球员对后续训练和比赛的准备可能会受到阻碍。 (C) 2016 年澳大利亚运动医学。由爱思唯尔有限公司出版。保留所有权利。
Objectives: Describe the effects of eastward long-haul transmeridian air travel on subjective jet-lag, sleep and wellness in professional football (soccer) players prior to the 2014 FIFA World Cup in Brazil.Design: Single cohort involving twenty-two male professional football players representing a national football team.Methods: Data was collected from players prior to and following international travel from Sydney, Australia to Vitoria, Brazil. In total there were three flights, 19-h and 14,695 km of travel east across 11 time-zones. Training load and wellness measures were obtained in the week prior to and following travel, whilst sleep and jet-lag measures were collected on the day prior to travel (Pre), the day of arrival and for five days following travel (Post 1-5).Results: Compared to Pre, perceived jet-lag was significantly increased on Post 1 to 4, with significantly greater levels on Post 1 compared to Post 5 (p < 0.05). Self-reported sleep duration during travel was 5.9 (4.8-7.0) h, which was significantly lower than all other nights (p < 0.01), except for the night of arrival, where time in bed and sleep duration were significantly reduced compared to Post 1-4 (p < 0.01). Lastly, compared to the week prior to travel, mean wellness was significantly reduced during the week following travel (p < 0.01).Conclusions: Self-reported sleep disruption during and following eastward long-haul transmeridian air travel, together with exacerbated jet-lag symptoms may result in reduced player wellness. Consequently, player preparedness for subsequent training and competition may be impeded, though physical performance data is lacking. (C) 2016 Sports Medicine Australia. Published by Elsevier Ltd.
