Wrist activity was monitored continuously for one year in a woman who went about her normal life. The year of data were analyzed for changes and rhythms--daily, weekly, menstrual, lunar, annual. For each day, average motions/5 minutes, activity onset, activity offset, alpha (duration of activity), and acrophase were measured. Periodograms and average daily wave forms were calculated. Well-defined, entrained, daily rest-activity cycles were observed throughout the year with periods close to 24 hours. There was weekend delay (0.7 hours) in onset, weekend decrease in alpha (1.0 hours), and weekend advance of acrophase (0.4 hours). Motions/5 minutes decreased 9%, onsets were 0.3 hours later, and alphas were 0.4 hours shorter on menstrual cycle days 8 through 18 which should have encompassed the time of ovulation. Lunar phase had no effect. Annual changes in onset (1.1 hours), offset (1.2 hours), and acrophase (1.1 hours) were attributed to the 1-hour change between standard and daylight savings time.
对一名正常生活的女性的手腕活动进行了为期一年的持续监测。对这一年的数据进行了变化和节律分析——包括每日、每周、月经周期、月相、年度节律。每天测量平均每5分钟的运动量、活动开始时间、活动结束时间、α（活动持续时间）和高峰相位。计算了周期图和每日平均波形。全年观察到明确的、有规律的每日休息-活动周期，周期接近24小时。周末活动开始时间延迟（0.7小时），周末α（活动持续时间）减少（1.0小时），周末高峰相位提前（0.4小时）。在月经周期的第8至18天（这应该涵盖了排卵时间），每5分钟的运动量减少了9%，活动开始时间晚了0.3小时，α缩短了0.4小时。月相对此没有影响。年度活动开始时间（1.1小时）、结束时间（1.2小时）和高峰相位（1.1小时）的变化归因于标准时间和夏令时之间1小时的变化。
