■COVID-19后受试者通常会出现疲劳症状,认知障碍,和睡眠困难,这可以通过传统的有氧运动来缓解。支持常规锻炼的虚拟现实(VR)技术最近获得了很多关注。因此,这项研究旨在评估与虚拟现实模拟跑步机运动相比,传统跑步机运动对疲劳的影响,认知功能,睡眠质量,以及参与者对COVID-19后受试者的锻炼计划的满意度。
■这种以单一为中心的,随机化,平行组干预研究于2021年12月至2022年3月间进行.20名COVID-19后受试者中有16名完成了这项研究(n1=8,n2=8)。纳入标准为持续性呼吸困难/疲劳,轻度认知问题,年龄在30-60岁之间。排除标准为既往严重COVID-19感染和入住ICU,伴随的呼吸道或心血管疾病,和肌肉骨骼或神经系统疾病。符合条件的受试者被随机分为两组:非VR组仅接受传统跑步机有氧运动,而VR组接受非沉浸式VR的跑步机运动。两组均在跑步机上进行中等强度运动[50-60%(峰值HR-静息HR)+静息HR]30-45分钟,每周三次,还有四个星期.结果测量是Chalder疲劳量表,蒙特利尔认知评估(MoCA)问卷,匹兹堡睡眠质量指数(PSQI)参与者对锻炼计划的满意度以5分利克特量表进行评分。
■两组的Chalder疲劳量表均有显著改善,MoCA问卷,训练后的PSQI得分与基线相比(p<0.05),二者之间无显著性差异(p>0.05)。然而,VR组参与者对锻炼计划的满意度显著高于非VR组(p=0.037).
■具有和不具有非沉浸式VR的中等强度的4周跑步机锻炼计划可能会改善疲劳,认知功能,COVID-19幸存者的睡眠质量达到相同程度。然而,在本队列中,与非沉浸式VR辅助的常规跑步机训练相比,参与者对锻炼计划的满意度可能更高.

UNASSIGNED: Post-COVID-19 subjects typically experience symptoms of fatigue, cognitive impairment, and sleep difficulty, which can be relieved by conventional aerobic exercise. Virtual Reality (VR) technology to support conventional exercise has recently gained much attention. Therefore, this study aimed to assess the effects of traditional treadmill exercise compared to virtual reality-simulated treadmill exercise on fatigue, cognitive function, sleep quality, and participant satisfaction with the exercise program in post-COVID-19 subjects.
UNASSIGNED: This single-centered, randomized, parallel-group intervention study was conducted between December 2021 and March 2022. Sixteen of twenty post-COVID-19 subjects completed this study (n1 = 8, n2 = 8). Inclusion criteria were persistent dyspnea/fatigue, mild cognitive problems, and age from 30-60 years. Exclusion criteria were previous severe COVID-19 infection and ICU admission, concomitant respiratory or cardiovascular disease, and musculoskeletal or neurological disease. Eligible subjects were assigned randomly to two groups: a non-VR group that received traditional treadmill aerobic exercise only and a VR group that received treadmill exercise with non-immersive VR. Both groups received moderate-intensity exercise on a treadmill at [50-60 % (peak HR-resting HR) + resting HR] for 30-45 min, three times per week, and for four weeks. The outcome measures were the Chalder Fatigue Scale, Montreal Cognitive Assessment (MoCA) questionnaire, Pittsburgh Sleep Quality Index (PSQI), and participant satisfaction with the exercise program rated on a 5-point Likert scale.
UNASSIGNED: Both groups showed significant improvements in the Chalder Fatigue Scale, the MoCA questionnaire, and the PSQI scores after training compared to baseline (p < 0.05), without significant differences between them (p > 0.05). However, participant satisfaction with the exercise program was significantly higher in the VR group than in the non-VR group (p = 0.037).
UNASSIGNED: A moderate-intensity 4-week treadmill exercise program with and without non-immersive VR may improve fatigue, cognitive function, and sleep quality to the same extent in COVID-19 survivors. However, participant satisfaction with the exercise program could be greater after conventional treadmill training assisted by non-immersive VR than after conventional treadmill training alone in this cohort.
