Regular physical activity (PA) is of central importance for healthy aging and has a well-known impact on helping older adults maintain their cognitive and physical health. Thus, we aimed to compare the effectiveness of two physical activity interventions primarily conducted at home (print-based or web-based vs. web-based plus the use of an activity tracker) on cognitive and physical health parameters in older adults. Data of participants ( = 551, 60-80 years) were analyzed after being randomly allocated to a waitlist control group (CG), a web-based or print-based intervention group (IG) or a web-based intervention group that also included the use of an activity tracker (AG). Measured parameters were grip strength, endurance (two-minute step test), gait speed (four-meter walk test), cognition (Simon task; balanced integration score (BIS), reaction time and accuracy) and physical self-concept (Physical Self-Description Questionnaire (PSDQ)). We found the highest effect sizes in all measured dimensions for AG (grip strength, endurance, gait speed, reaction time, physical self-concept), followed by IG (endurance, gait speed, reaction time, physical self-concept) and CG (endurance, gait speed, BIS). Findings suggest that a combined web-based and activity tracker intervention may improve physical functions, physical self-concept, and cognition in community-dwelling older adults.
定期进行身体活动（PA）对健康老龄化至关重要，并且众所周知，它对帮助老年人保持认知和身体健康有积极影响。因此，我们旨在比较两种主要在家中进行的身体活动干预措施的效果（基于印刷品或基于网络的干预与基于网络的干预加活动追踪器的使用）对老年人的认知和身体健康参数的影响。对随机分配到等待名单对照组（CG）、基于网络或基于印刷品的干预组（IG）或还包括使用活动追踪器的基于网络的干预组（AG）的参与者的数据进行了分析。测量的参数包括握力、耐力（两分钟踏步测试）、步速（四米步行测试）、认知（Simon 任务；平衡综合评分（BIS）、反应时间和准确性）和身体自我概念（身体自我描述问卷（PSDQ））。我们发现 AG 在所有测量维度上的效果最高（握力、耐力、步速、反应时间、身体自我概念），其次是 IG（耐力、步速、反应时间、身体自我概念）和 CG（耐力、步速、BIS）。研究结果表明，结合基于网络和活动追踪器的干预措施可能会改善社区居住的老年人的身体机能、身体自我概念和认知能力。
