Abstract：
Physical inactivity among older adults remains a global burden, leading to a variety of health challenges and even mortality. This study evaluated the impact of a novel virtual humanoid coach-driven physical exercise program among older adults. A non-randomized (quasi) experimental research was conducted in two community senior centers. The recruited participants (n = 130) were primarily female older adults with a mean age of 66.40 and agreed to be purposively assigned either experimental or control groups. Trained healthcare providers performed health assessments in three time points using valid and reliable tools. Descriptive statistics, t-tests, and RM-ANOVA were used to quantitatively analyze the data using SPSS version 22. There are significant mean differences between the groups across all functional capacity assessments and Time 2-3 assessment of sleep quality. RM-ANOVA revealed significant differences in physical assessment over time between the two groups. The analyses of time and group interaction revealed significant improvement in health assessments among the members of the mixed reality group compared to the traditional groups. The impact of virtual coaches in community-based enhancing physical activity programs is comparable to the traditional mode and introduces a novel approach to promoting physical activity among older adults.
摘要：
老年人缺乏身体活动仍然是全球负担，导致各种健康挑战甚至死亡。这项研究评估了新型虚拟人形教练驱动的体育锻炼计划对老年人的影响。在两个社区高级中心进行了非随机（准）实验研究。招募的参与者（n=130）主要是女性老年人，平均年龄为66.40岁，并同意有目的地分配实验组或对照组。训练有素的医疗保健提供者使用有效和可靠的工具在三个时间点进行健康评估。描述性统计，t检验,和RM-ANOVA用于使用SPSS版本22对数据进行定量分析。在所有功能能力评估和睡眠质量的时间2-3评估中,组间存在显著的平均差异。RM-ANOVA显示两组之间随时间的物理评估存在显着差异。对时间和小组互动的分析表明，与传统小组相比，混合现实小组成员之间的健康评估显着改善。虚拟教练在基于社区的增强体育活动计划中的影响与传统模式相当，并引入了一种新颖的方法来促进老年人的体育活动。
