Wrist activity was monitored in 17 college students for 11-15 days each. Records of individuals had distinctive patterns, like fingerprints. The subjects all exhibited daily cycles in their activity with activity during the daytime and with period lengths close to 24 h. There was individual variation in average phase (onset 5.3 h, offset 4.5 h, acrophase 6.1 h). Individual subjects all showed 7-day oscillations in their activity patterns associated with the weekly work-leisure schedules. During the leisure weekends, the subjects as a group had a 2.1-h delay in onset, a 1.5-h delay in acrophase, and a 0.8-h shortening in alpha.
对17名大学生的手腕活动进行了监测，每人监测11至15天。个人记录有独特的模式，就像指纹一样。所有受试者的活动都呈现出日周期，白天活动，周期长度接近24小时。平均相位存在个体差异（开始时间5.3小时，结束时间4.5小时，高峰相位6.1小时）。个体受试者的活动模式均表现出与每周工作-休闲安排相关的7天振荡。在休闲的周末，作为一个群体的受试者开始时间延迟2.1小时，高峰相位延迟1.5小时，α时长缩短0.8小时。
