研究的目的是确定学龄前儿童的午睡习惯是否与久坐时间和身体活动(运动行为)有关，(2)午睡生理与运动行为有关，以及(3)如果缺少午睡，与午睡相比，是否会影响当天和随后一天的运动行为。在一项受试者内部(44名儿童；4.2 ± 0.6岁；55.6%女性)的居家研究中，检查了两种实验条件(午睡和清醒促进各一个下午的顺序平衡)，间隔一周。运动行为由腕式肌动描记(12.1 ± 3.1天)获得。平均运动行为是从整个研究期间计算出来的，不包括实验天数。在两种实验条件下，分别提取当天和次日的运动行为。记录睡眠促进状态下的多导睡眠图。儿童被归类为不午睡、中间午睡或习惯性午睡。尽管午睡习惯组之间的平均运动行为有所不同，但差异不显著。运动行为与午睡睡眠阶段无关，午睡习惯对当天或次日运动行为的影响也不显著。研究结果并不表明午睡和儿童的运动行为有关。尽管错过一次午睡对同一天或第二天的运动行为没有不利影响，但未来的研究应该探索随后几天限制午睡的影响，以检查潜在的累积影响。
The objective was to determine if, in preschool-aged children, (1) nap habituality is associated with sedentary time and physical activity (movement behaviors), (2) nap physiology is associated with movement behaviors, and (3) if missing a nap, compared to taking a nap, affects movement behaviors on the same day and subsequent day. A within-subjects (44 children; 4.2 ± 0.6 years; 55.6% female), at-home study examined two experimental conditions (one afternoon each of nap- and wake-promotion with order counterbalanced) one week apart. Movement behaviors were derived from wrist-worn actigraphy (12.1 ± 3.1 days). Average movement behaviors were calculated from the overall study period with experimental days excluded. Movement behaviors were also extracted for the same day and the subsequent day of the two experimental conditions. Polysomnography was recorded during the nap-promoted condition. Children were classified as non-, intermediate-, or habitual-nappers. Although average movement behaviors were different between nap habituality groups, differences were not significant. There were no associations between movement behaviors and nap sleep stages, and no effects for nap condition or condition by nap habituality on same or next day movement behaviors. Findings do not suggest that naps and movement behaviors are related in children. Although a single missed nap was not detrimental to same or next day movement behaviors, future studies should explore effects of multiple days of subsequent nap restriction to examine potential cumulative effects.
