Recent studies have shown potentially detrimental effects of the COVID-19 pandemic on physical activity (PA) in emerging adults (ages 18-29 y). However, studies that examined the effects of COVID-19 on PA location choices and maintenance for this age group remain limited. The current study investigated changes in PA location choices across 13 months during the pandemic and their associations with PA maintenance in this population.
Emerging adults (N = 197) living in the United States completed weekly survey on personal smartphones (May 2020-June 2021) regarding PA location choices and maintenance. Mixed-effects models examined the main effects of PA location choice and its interaction with weeks into the pandemic on participants' PA maintenance.
On a given week, participants performing PA on roads/sidewalks or at parks/open spaces were 1½ and 2 times as likely to maintain PA levels, respectively. Moreover, after September 2021, weeks when individuals performed PA on roads/sidewalks had a protective effect on PA maintenance.
Performing PA on roads/sidewalks and at parks/open spaces was associated with PA maintenance during the COVID-19 pandemic. PA promotion and intervention efforts for emerging adults during large-scale disruptions to daily life should focus on providing programmed activities in open spaces to maintain their PA levels.
最近的研究表明，COVID-19 大流行对 18-29 岁的年轻人的身体活动（PA）可能产生不利影响。然而，研究 COVID-19 对该年龄段 PA 地点选择和维持的影响的研究仍然有限。本研究调查了大流行期间 13 个月内 PA 地点选择的变化及其与该人群 PA 维持的关系。
居住在美国的年轻成年人（N=197）使用个人智能手机每周完成一次关于 PA 地点选择和维持的调查（2020 年 5 月至 2021 年 6 月）。混合效应模型检查了 PA 地点选择的主要影响及其与大流行期间周数的相互作用对参与者 PA 维持的影响。
在给定的一周内，分别在道路/人行道上和公园/开放空间进行 PA 的参与者维持 PA 水平的可能性分别是前者的 1.5 倍和 2 倍。此外，在 2021 年 9 月之后，个体在道路/人行道上进行 PA 的周数对 PA 维持有保护作用。
在 COVID-19 大流行期间，在道路/人行道上和公园/开放空间进行 PA 与 PA 维持有关。在日常生活受到大规模干扰期间，针对年轻成年人的 PA 促进和干预措施应侧重于在开放空间提供有计划的活动，以维持他们的 PA 水平。
