Jet lag and travel fatigue can occur after crossing multiple time zones in a short period of time, possibly affecting various aspects of an athlete's behavior. However, there are few studies regarding this issue, particularly considering junior athletes. This study aimed to investigate and quantify the symptoms of jet lag and travel fatigue and the factors impacting these conditions. A survey was completed by 41 Japanese junior athletes (21 men and 20 women), competing at an international game in Finland, to assess their performance, sleeping habits, digestion, fatigue, and jet lag on the first day of arrival and on the opening day of the competition. Although athletes awoke less often during sleep on the opening day of the competition compared with the first day, sleep time, ease of falling asleep, and sleep quality decreased significantly. Prior experience traveling abroad for international competitions was positively associated with improvements regarding ease of falling asleep (coefficient = 2.22, = 0.01), quality of sleep (coefficient = 2.16, = 0.02), and alertness after waking up (coefficient = 1.85, = 0.05) by the opening day of the competition when compared with the results for athletes who had no such prior experiences. Junior athletes experience symptoms of jet lag and travel fatigue that may persist until the day of competition, and prior experience traveling abroad may help in alleviating their symptoms.
在短时间内跨越多个时区后，可能会出现时差反应和旅行疲劳，这可能会影响运动员行为的各个方面。然而，关于这个问题的研究很少，尤其是针对青少年运动员。本研究旨在调查和量化时差反应和旅行疲劳的症状以及影响这些状况的因素。41名日本青少年运动员（21名男性和20名女性）完成了一项调查，他们在芬兰参加一场国际比赛，以评估他们在抵达首日和比赛开幕日的表现、睡眠习惯、消化情况、疲劳程度和时差反应。尽管与第一天相比，运动员在比赛开幕日睡眠期间醒来的次数较少，但睡眠时间、入睡难易程度和睡眠质量都显著下降。与没有此类出国参加国际比赛经历的运动员相比，有出国参加国际比赛经历与到比赛开幕日时入睡难易程度的改善（系数=2.22，P=0.01）、睡眠质量的改善（系数=2.16，P=0.02）以及醒来后的警觉性的改善（系数=1.85，P=0.05）呈正相关。青少年运动员会经历时差反应和旅行疲劳的症状，这些症状可能会持续到比赛当天，而出国旅行的经历可能有助于缓解他们的症状。
