目的本研究的主要目的是检查在自然环境中的身体活动（PA）（例如，“绿色运动”）对Walks4Work干预中静息自主神经功能的影响。第二个目的是评估可行性Walks4Work的坚持，PA水平的变化，和心血管健康parameters.Methods在一个为期8周的随机对照试验，94名办公室工作人员在一家国际公司被分配到三个组之一：控制，自然（NW），或建成（BW）午餐步行路线。两个步行组都被要求每周进行两次午餐散步。西北线以树木、草地和公共人行道为中心。相比之下，BW由穿过住宅区和工业区的人行道组成。在基线和干预后收集数据。结果共有73名参与者完成了干预（脱落率为22%）。两组间静息自主神经功能无差异。只有NW组的自我报告的心理健康有所改善。PA水平增加在干预中点的所有组相结合，但坚持干预的BW和NW groups.Conclusions内的42%和43%的率低，伴随着两个积极的午餐时间，每周与低主持人输入的指南似乎不足以增加积极的午餐时间和修改心血管健康参数在办公室人群。然而，这一人群属于心血管指标的正常范围，未来的研究应考虑调查高危人群，特别是高血压患者。
Objectives The primary aim of this study was to examine the impact of physical activity (PA) in the natural environment (eg, "green exercise") on resting autonomic function in the Walks4Work intervention. A secondary aim was to assess the feasibility of Walks4Work in terms of adherence, change in PA levels, and cardiovascular health parameters.Methods In an 8-week randomized control trial, 94 office workers in an international company were allocated to one of three groups: control, nature (NW), or built (BW) lunchtime walking route. Both walking groups were required to undertake two lunchtime walks each week. The NW route centered around trees, maintained grass, and public footpaths. In contrast, the BW consisted of pavement routes through housing estates and industrial areas. Data were collected at baseline and following the intervention. To investigate the impact of the intervention, mixed-design analysis of variance (ANOVA) were performed.Results A total of 73 participants completed the intervention (drop-out rate of 22%). No difference was observed in resting autonomic function between the groups. Self-reported mental health improved for the NW group only. PA levels increased at the intervention mid-point for all groups combined but adherence to the intervention was low with rates of 42% and 43% within the BW and NW groups, respectively.Conclusion Accompanying a guideline of two active lunchtimes per week with low facilitator input appears inadequate for increasing the number of active lunchtimes and modifying cardiovascular health parameters in an office population. However, this population fell within normal ranges for cardiovascular measures and future research should consider investigating at-risk populations, particularly hypertensive individuals.
