OBJECTIVE
The aim of this study was to determine whether individuals who participated in an intervention to reduce sitting at work would report changes in arousal, fatigue, and mood.
METHODS
Inactive females with full-time sedentary occupations (N = 49) were randomly assigned to take short, frequent breaks (SBs) or longer, planned breaks (LBs) from sitting each workday for 8 weeks. At baseline and postintervention, participants completed measures of arousal, fatigue, and mood. Within- and between-group changes were examined.
RESULTS
SB participants reduced sitting and reported moderate to large improvements in all affective outcomes except calmness (d = -0.44 to -0.82), whereas effect sizes were small for the LB group (d = 0.01 to -0.28). Only changes in negative affect differed between groups (P = 0.045).
CONCLUSION
This study suggests that taking short, frequent breaks from sitting may be an effective strategy for improving affective outcomes among sedentary female employees.
目的
本研究旨在确定参与减少工作中久坐干预的个体是否会报告警觉性、疲劳和情绪的变化。
方法
久坐的女性（N=49）随机分配到每天工作中短时间、频繁休息（SB）或长时间、计划休息（LB）组，持续 8 周。在基线和干预后，参与者完成了警觉性、疲劳和情绪的测量。检查了组内和组间的变化。
结果
SB 组减少了久坐时间，并报告除平静感（d=-0.44 至-0.82）外，所有情感结果均有中度至较大改善，而 LB 组的效果较小（d=0.01 至-0.28）。只有负面情绪的变化在组间存在差异（P=0.045）。
结论
本研究表明，短时间、频繁地从坐姿中休息可能是改善久坐女性员工情感结果的有效策略。
