Three studies were performed to evaluate the effects of jet lag on factors associated with sport performance. In Study 1, members of the USA Women's Soccer Team traveled to Taiwan; in Study 2, North American students and faculty traveled to Western Europe; and in Study 3, European students traveled to North America. After travel, there was disruption of mood state and a reduction in dynamic strength; peak 5-s power and 30-s work capacity were reduced for 2 days (5-s power: 9.8 vs. 9.0 vs. 9.0 W.kg-1; 30-s work capacity: 213 vs. 199 vs. 201 J.kg-1). In these studies, mood state, anaerobic power and capacity, and dynamic strength were affected by rapid transmeridianal travel, and even highly trained athletes suffered from jet lag. However, effects of travel on the variables tested were essentially eliminated after 3 or 4 days.
进行了三项研究以评估时差对与运动表现相关因素的影响。在研究1中，美国女子足球队队员前往台湾；在研究2中，北美学生和教师前往西欧；在研究3中，欧洲学生前往北美。旅行后，情绪状态受到干扰，动态力量下降；5秒峰值功率和30秒工作能力降低了2天（5秒功率：9.8 vs. 9.0 vs. 9.0 W.kg-1；30秒工作能力：213 vs. 199 vs. 201 J.kg-1）。在这些研究中，情绪状态、无氧功率和能力以及动态力量受到快速跨子午线旅行的影响，即使是训练有素的运动员也会受到时差的影响。然而，旅行对所测试变量的影响在3或4天后基本消除。
