Abstract：
This study investigated whether strength, balance, body mass index, falls self-efficacy, activity levels, self-rated health, and participation in a multicomponent exercise intervention could predict physical activity levels after 5 months of self-quarantine due to the COVID-19 pandemic. This study included baseline data of 200 community-dwelling older adults (79% women, 21% men) with a mean age of 72 years who participated in a randomized controlled trial investigating a multicomponent exercise program, with 7-month follow-up survey data of their physical activity levels. The results showed significant associations with the activity levels at the 7-month follow-up. The activity levels (odds ratio (OR): 2.83, 95% CI: 1.20-6.71), the self-rated health score (2.80, 1.42-5.53), and being allocated to a specific multicomponent group-based exercise program (2.04, 1.04-4.00) showed a significant association with the activity habits at the 7-month follow-up. As this study suggests, besides the physical activity levels and the self-rated health score, participation in a high challenge multicomponent exercise program was significantly associated with physical activity levels at the 7-month follow-up. This study indicates that a relatively short multicomponent group exercise program (6-9 weeks) can motivate individuals to sustain their own training and activity levels even several months after the program has been paused or terminated. Identifying older adults\' physical activity levels and self-rated health scores and prescribing multicomponent group-based exercise programs to promote sustained physical activity habits may be a successful alternative to provide for older adults in the future.
摘要：
这项研究调查了强度，balance,身体质量指数,跌倒自我效能感，活动水平,自我评估的健康，参与多组分运动干预可以预测因COVID-19大流行而进行自我隔离5个月后的身体活动水平。这项研究包括200名社区居住的老年人的基线数据(79%的女性，21％的男性），平均年龄为72岁，参加了一项研究多组分锻炼计划的随机对照试验，与7个月的跟踪调查数据，他们的身体活动水平。结果显示在7个月的随访中与活动水平显著相关。活动水平(比值比(OR)：2.83，95%CI：1.20-6.71)，自评健康评分（2.80，1.42-5.53），在7个月的随访中，被分配到特定的基于多组分组的运动计划（2.04，1.04-4.00）与活动习惯显着相关。正如这项研究所表明的，除了身体活动水平和自我评估的健康评分，在7个月的随访中,参加高挑战性多成分锻炼计划与身体活动水平显著相关.这项研究表明，相对较短的多组分小组锻炼计划（6-9周）可以激励个人在计划暂停或终止后几个月内维持自己的训练和活动水平。确定老年人的身体活动水平和自我评估的健康评分，并制定基于小组的多组分锻炼计划以促进持续的身体活动习惯，可能是未来为老年人提供的成功替代方案。
