The use of tele-exercise programs as an option for post-COVID-19 rehabilitation has been suggested, but its effectiveness in non-hospitalized individuals is not well understood.
This study aimed to determine the effectiveness of an 8-week tele-exercise training program (COFIT-HK) on physical fitness, functional capacity, and health-related quality of life (HRQoL) in non-hospitalized post-COVID-19 individuals.
Forty-one non-hospitalized individuals (age:47.4 ± 7.8 yrs) who had COVID-19 history were divided into two groups: the tele-exercise training group (TELE; n = 21) and the non-intervention control group (CON; n = 20). TELE engaged in online supervised multicomponent low-to-moderate intensity exercise training (including respiratory muscle, aerobic, and resistance training) three times per week, whereas CON received standardized educational leaflets based on World Health Organization (WHO) guidelines for post-COVID-19-related illness rehabilitation only. Various components of physical fitness, functional capacity, and HRQoL were assessed at baseline and after the 8-week intervention.
TELE showed significant improvements in handgrip strength, arm flexibility, functional lower extremity endurance, and HRQoL after the 8-week intervention (all < 0.05, ES = 0.50-1.10). When comparing the groups, TELE demonstrated significantly greater improvements in both the physical and mental component summary scores of HRQoL compared to CON (both < 0.05). Other outcomes did not reveal significant group differences.
Our tele-exercise intervention was effective in improving physical fitness, functional capacity and HRQoL among non-hospitalized post-COVID-19 individuals. Further research is needed to explore the utility and limitations of tele-exercise programs for post-COVID-19 rehabilitation and beyond.
有人建议将远程锻炼计划作为新冠疫情后康复的一种选择，但其在非住院患者中的有效性尚不清楚。
本研究旨在确定为期8周的远程锻炼训练计划（COFIT-HK）对非住院的新冠康复患者的体能、功能能力和健康相关生活质量（HRQoL）的有效性。
41名有新冠病史的非住院患者（年龄：47.4±7.8岁）被分为两组：远程锻炼训练组（TELE；n = 21）和非干预对照组（CON；n = 20）。TELE组每周进行三次在线监督的多组分低至中等强度运动训练（包括呼吸肌、有氧运动和阻力训练），而CON组仅收到基于世界卫生组织（WHO）新冠疫情后相关疾病康复指南的标准化教育传单。在基线和8周干预后评估体能、功能能力和HRQoL的各个组成部分。
8周干预后，TELE组在握力、手臂灵活性、下肢功能耐力和HRQoL方面有显著改善（均P<0.05，ES = 0.50 - 1.10）。在比较两组时，与CON组相比，TELE组在HRQoL的身体和心理组成部分总分上的改善显著更大（均P<0.05）。其他结果未显示出显著的组间差异。
我们的远程锻炼干预有效地改善了非住院的新冠康复患者的体能、功能能力和HRQoL。需要进一步研究以探索远程锻炼计划在新冠疫情后康复及其他方面的效用和局限性。
