Wrist motions (223-471)/5 min were measured during 17-32 days of continuous recordings made from human passengers as they traveled across zero to five time zones for business and pleasure. The travelers all exhibited daily cycles of activity and rest. The duration of daily activity, alpha, was 1.1 h less at the destination; the mean was 63 wrist motions/5 min less at the destination. Phase shifts of the daily rhythm (e.g., acrophases, 0.0 to 5.3 h) advanced or delayed in the direction expected from time zone changes. However, the magnitude of the phase shifts differed (e.g., as much as 2.3 h) from the expected changes because of transmeridian travel and there were phase shifts even when there was no change in time zone. Differences were observed in phase shifts assessed by different methodologies of determining phase (waveforms, onsets, offsets, acrophases).
在17至32天的连续记录中，测量了人类乘客在跨越0至5个时区进行商务和休闲旅行时的手腕运动（223 - 471次/5分钟）。所有旅行者都表现出日常的活动和休息周期。到达目的地时，每日活动时长α减少了1.1小时；在目的地，平均每5分钟的手腕运动次数减少了63次。每日节律的相位偏移（例如，峰相位，提前或延迟0.0至5.3小时）朝着时区变化预期的方向推进或延迟。然而，由于跨子午线旅行，相位偏移的幅度（例如，多达2.3小时）与预期变化不同，并且即使在时区没有变化时也会出现相位偏移。在通过不同的相位确定方法（波形、起始点、终点、峰相位）评估的相位偏移中观察到了差异。
