A significant association has been identified between physical activity and proximity to greenways. However, residents more likely to be active may have selected to live near existing greenways. The purpose of this study was to determine whether development of a new greenway has the potential to increase activity levels of existing, proximate residents.
In 2008, survey data were collected before and after 5 miles of greenway were added to an existing greenway.
When comparing residents living nearest (≤ .50 miles) the new greenway section with those living further (.51-1.0 miles), days spent walking and participating in moderate physical activity increased. Despite mean increases, no significant interactions were detected.
Although evidence is inconclusive, apparent increases in walking and moderate activity suggest development of a greenway proximate to residents' homes is likely to have a positive effect on participation levels. Additional research is needed to address article limitations.
已确定身体活动与靠近绿色通道之间存在显著关联。然而，更有可能积极活动的居民可能选择居住在现有绿色通道附近。本研究的目的是确定新建绿色通道是否有可能提高附近现有居民的活动水平。
2008年，在一条现有绿色通道增加5英里的绿色通道前后收集了调查数据。
将居住在最靠近（≤0.50英里）新建绿色通道段的居民与居住较远（0.51 - 1.0英里）的居民进行比较时，步行天数和参与适度身体活动的天数增加。尽管有平均增加，但未检测到显著的相互作用。
尽管证据尚无定论，但步行和适度活动的明显增加表明，在居民家附近修建绿色通道可能会对参与水平产生积极影响。需要进行更多研究以解决本文的局限性。
