Infections with the coronavirus disease 2019 (COVID-19) and disorders of the heart and blood vessels are causally related. To ascertain the causal relationship between COVID-19 and cardiovascular disease (CVD), we carried out a Mendelian randomization (MR) study through a method known as inverse variance weighting (IVW). When analyzing multiple SNPs, MR can meta-aggregate the effects of multiple loci by using IVW meta-pooling method. The weighted median (WM) is the median of the distribution function obtained by ranking all individual SNP effect values according to their weights. WM yields robust estimates when at least 50% of the information originates from valid instrumental variables (IVs). Directed gene pleiotropy in the included IVs is permitted because MR–Egger does not require a regression straight line through the origin. For MR estimation, IVW, WM and MR-Egger were employed. Sensitivity analysis was conducted using funnel plots, Cochran's Q test, MR–Egger intercept test, MR–PRESSO, and leave-one-out analysis. SNPs related to exposure to COVID-19 and CVD were compiled. CVD for COVID-19 infection, COVID-19 laboratory/self-reported negative, and other very severe respiratory diagnosis and population were randomly assigned using MR. The COVID-19 laboratory/self-reported negative results and other very severe respiratory confirmed cases versus MR analysis of CVD in the population (p ​> ​0.05); COVID-19 infection to CVD (p ​= ​0.033, OR ​= ​1.001, 95%CI: 1.000–1.001); and the MR–Egger results indicated that COVID-19 infection was associated with CVD risk. This MR study provides preliminary evidence for the validity of the causal link between COVID-19 infection and CVD.

2019年冠状病毒病（COVID-19）感染与心脏和血管疾病存在因果关系。为了确定 COVID-19 与心血管疾病（CVD）之间的因果关系，我们通过一种称为逆方差加权（IVW）的方法进行了孟德尔随机化（MR）研究。在分析多个 SNPs 时，MR 可通过 IVW 元池化法对多个位点的效应进行元聚合。加权中值（WM）是根据所有单个 SNP 效应值的权重进行排序后得到的分布函数的中值。当至少 50%的信息来源于有效的工具变量（IVs）时，加权中值会产生稳健的估计值。由于 MR-Egger 不要求通过原点的回归直线，因此允许在所包含的 IV 中存在定向基因多向性。MR 估计采用了 IVW、WM 和 MR-Egger。使用漏斗图、Cochran's Q 检验、MR-Egger 截距检验、MR-PRESSO 和leave-one-out 分析进行了敏感性分析。汇编了与 COVID-19 暴露和心血管疾病相关的 SNPs。COVID-19感染的心血管疾病、COVID-19实验室/自我报告阴性以及其他非常严重的呼吸系统诊断和人群使用MR进行随机分配。COVID-19 实验室/自报阴性结果和其他非常严重的呼吸道确诊病例与 MR 分析人群的心血管疾病相关（p > 0.05）；COVID-19 感染与心血管疾病相关（p = 0.033，OR = 1.001，95%CI：1.000-1.001）；MR-Egger 结果表明，COVID-19 感染与心血管疾病风险相关。这项 MR 研究为 COVID-19 感染与心血管疾病之间因果关系的有效性提供了初步证据。

Functional near-infrared spectroscopy (fNIRS) was used to explore the effects of sedentary behavior on the brain functional connectivity characteristics of college students in the resting state after recovering from Corona Virus Disease 2019 (COVID-19). Twenty-two college students with sedentary behavior and 22 college students with sedentary behavior and maintenance of exercise habits were included in the analysis; moreover, 8 ​min fNIRS resting-state data were collected. Based on the concentrations of oxyhemoglobin (HbO2) and deoxyhemoglobin (HbR) in the time series, the resting-state functional connection strength of the two groups of subjects, including the prefrontal cortex (PFC) and the lower limb supplementary motor area (LS), as well as the functional activity and functional connections of the primary motor cortex (M1) were calculated. The following findings were demonstrated. (1) Functional connection analysis based on HbO2 demonstrated that in the comparison of the mean functional connection strength of homologous regions of interest (ROIs) between the sedentary group and the exercise group, there was no significant difference in the mean functional strength of the ROIs between the two groups (p>0.05). In the comparison of the mean functional connection strengths of the two groups of heterologous ROIs, the functional connection strengths of the right PFC and the right LS (p=0.0097), the left LS (p=0.0127), and the right M1 (p=0.0305) in the sedentary group were significantly greater. The functional connection strength between the left PFC and the right LS (p=0.0312) and the left LS (p=0.0370) was significantly greater. Additionally, the functional connection strength between the right LS and the right M1 (p=0.0370) and the left LS (p=0.0438) was significantly greater. (2) Functional connection analysis based on HbR demonstrated that there was no significant difference in functional connection strength between the sedentary group and the exercise group (p>0.05) or between the sedentary group and the exercise group (p>0.05

研究人员利用功能近红外光谱（fNIRS）探讨了久坐行为对大学生从2019年科罗纳病毒病（COVID-19）康复后静息状态下大脑功能连接特性的影响。22名有久坐行为的大学生和22名有久坐行为并保持运动习惯的大学生被纳入分析；此外，还收集了8分钟的fNIRS静息态数据。根据时间序列中氧合血红蛋白（HbO2）和脱氧血红蛋白（HbR）的浓度，计算两组受试者的静息状态功能连接强度，包括前额叶皮层（PFC）和下肢辅助运动区（LS），以及初级运动皮层（M1）的功能活动和功能连接。研究结果如下(1）基于 HbO2 的功能连接分析表明，在比较久坐组和运动组同源感兴趣区（ROIs）的平均功能连接强度时，两组 ROIs 的平均功能强度无显著差异（p>0.05）。在两组异源ROI平均功能连接强度的比较中，久坐组的右侧PFC与右侧LS（p=0.0097）、左侧LS（p=0.0127）和右侧M1（p=0.0305）的功能连接强度明显更大。左侧 PFC 与右侧 LS（p=0.0312）和左侧 LS（p=0.0370）之间的功能连接强度明显更大。此外，右侧 LS 与右侧 M1（p=0.0370）和左侧 LS（p=0.0438）之间的功能连接强度也明显更大。(2) 基于 HbR 的功能连接分析表明，久坐组与运动组之间（p>0.05）或久坐组与运动组之间（p>0.05）的功能连接强度无明显差异。同样，两组同源和异源 ROI 的平均功能连接强度也无明显差异。此外，两组 ROI 的平均功能强度也无明显差异（p>0.05）。实验结果和基于功能连接的图表分析表明，在本实验中，表现出久坐行为的大学生参与者的 fNIRS 信号有所增加。表现出久坐行为的大学生的 fNIRS 信号增加可能与他们感染 SARS-CoV-2 后的状态和久坐的环境有关，这可能是静息态大脑皮层网络功能连接加强的原因。相反，有运动行为的参与者的 fNIRS 信号则有所下降，他们在与久坐者相同的条件下保持了合理的运动习惯。这些结果可能表明，运动行为有可能减轻和减少久坐行为对静息状态大脑皮层网络的影响。

Background

Postural control deficits and persistent joint stability issues are prevalent in population with anterior cruciate ligament (ACL) injuries or reconstructions. Postural control is typically assessed using the center of pressure (CoP) parameters during the static single-leg stance with a force plate. However, previous studies have reported unclear definitions and descriptions of the CoP parameters, causing inconsistent results of postural control deficits in a specific population.

Objective

To 1) summarize CoP parameters commonly used to evaluate postural control deficits in ACL injured or reconstructed population, and 2) identify the differences in CoP parameters with opened and closed eyes during the single-leg stance between ACL injured or reconstructed and control groups.

Methods

PubMed, Embase, Cochrane Library, CINAHL, Scopus, Web of Science, and SPORTDiscus databases were searched up to July 2023. Data were obtained from the selected articles and underwent quality and risk of bias assessment and meta-analysis using random-effect models. Subgroup analysis within ACL injured or reconstructed group were also performed.

Results

A total of 14 articles were included in the analysis after screening. The injured knee of the ACL injured or reconstructed group differed insignificantly in sway amplitude, sway area, and sway velocity during static single-leg stance under opened and closed eyes when compared with the control group. In the subgroup analysis, we found that there was only significant difference in sway velocity with open eyes (SMD ​= ​0.47, p ​= ​0.001) between ACL reconstructed group and control group.

Conclusion

This study summarized the common CoP parameters used to evaluate postural control in ACL injured or reconstructed population. The results only showed weak difference in sway velocity between ACL reconstructed population and healthy individuals with opened eyes during the static single-leg stance.
背景前交叉韧带（ACL）损伤或重建人群中普遍存在姿势控制缺陷和持续性关节稳定性问题。姿势控制的评估通常使用压力板静态单腿站立时的压力中心（CoP）参数。然而，之前的研究对 CoP 参数的定义和描述不明确，导致特定人群姿势控制缺陷的结果不一致。目的1）总结常用于评估前交叉韧带损伤或重建人群姿势控制缺陷的 CoP 参数；2）确定前交叉韧带损伤或重建组和对照组在单腿站立时睁眼和闭眼 CoP 参数的差异。方法检索了截至 2023 年 7 月的 PubMed、Embase、Cochrane Library、CINAHL、Scopus、Web of Science 和 SPORTDiscus 数据库。从所选文章中获取数据，进行质量和偏倚风险评估，并使用随机效应模型进行荟萃分析。结果 经过筛选，共有 14 篇文章被纳入分析。与对照组相比，前交叉韧带损伤或重建组受伤膝关节在睁眼和闭眼静态单腿站立时的摇摆幅度、摇摆面积和摇摆速度差异不明显。在亚组分析中，我们发现前交叉韧带重建组与对照组仅在睁眼时的摇摆速度上存在显著差异（SMD = 0.47，P = 0.001）。结果显示，在静态单腿站立时，前交叉韧带重建人群与健康人群在睁眼时的摇摆速度存在微弱差异。

Background

Ankle-foot sprains are the most common musculoskeletal injuries, which can impair balance and theoretically increase the risk of falls, but still, there is a lack of evidence supporting the direct association between ankle-foot sprains and the future risk of falls.

Methods

UK Biobank cohort was utilized to measure the association between ankle-foot sprains and fall risk with covariates adjusted. Then, the two-sample Mendelian randomization (MR) analysis was applied based on the genetically predicated ankle-foot sprains from FinnGen to validate causal relationship. Finally, genetically predicated cerebellar neuroimaging features were used to explore the mediating role of maladaptive neuroplasticity between ankle-foot sprains and falls by two-step MR analyses.

Results

Patients with ankle-foot sprains history exhibited a slightly increased risk of falls than the matched controls before and after adjustment for covariates (odd ratio [OR] ranged from 1.632 to 1.658). Two-sample MR analysis showed that ankle-foot sprains led to a higher risk of falls (OR ​= ​1.036) and a lower fractional anisotropy of superior cerebellar peduncle (SCP) (left, β ​= ​−0.052; right, β ​= ​−0.053). A trend of mediating effect was observed for the fractional anisotropy of right SCP in the causal effects of ankle-foot sprains on falls (β ​= ​0.003).

Conclusion

The history of ankle-foot sprains is associated with a slightly increased risk of falls. These findings improve our understanding of the clinical consequences of ankle-foot sprains in terms of fall risk and suggest the importance of adopting more efficient strategies for managing residual functional deficits after the injuries.
踝关节扭伤是最常见的肌肉骨骼损伤，它会损害平衡，理论上会增加跌倒的风险，但是，仍然缺乏证据支持踝关节扭伤与未来跌倒风险之间的直接联系。方法采用suk Biobank队列方法，通过调整协变量，测量踝关节扭伤与跌倒风险的相关性。然后，基于FinnGen的遗传预测踝足扭伤，应用双样本孟德尔随机化（MR）分析来验证因果关系。最后，通过两步磁共振分析，利用遗传预测的小脑神经影像学特征来探索踝足扭伤和跌倒之间神经可塑性不良的中介作用。结果在协变量调整前后，有踝关节-足部扭伤史的患者跌倒风险略高于对照组（奇比[OR]范围为1.632 ~ 1.658）。双样本MR分析显示，踝关节-足部扭伤导致较高的跌倒风险（OR = 1.036）和较低的小脑上脚（SCP）各向异性分数(左，β =−0.052；对，β = - 0.053)。右SCP分数各向异性在踝关节-足部扭伤对跌倒的因果效应中有中介作用的趋势（β = 0.003）。结论踝关节-足部扭伤史与跌倒风险略有增加相关。这些发现提高了我们对踝关节-足部扭伤在跌倒风险方面的临床后果的理解，并建议采用更有效的策略来管理损伤后残余功能缺陷的重要性。

It is well-known that not meeting the 24-hours (h) movement guidelines, including insufficient physical activity (PA), excessive sedentary behavior (SB), inadequate sleep duration, and their combinations, are independent risk factors for noncommunicable diseases (NCDs). The prevalence of not meeting the guidelines is high across the world, especially in China where has one of the largest population. Some studies have estimated the economic cost of insufficient PA in China, which is useful to guide policymakers to develop and implement effective health actions. However, several research gaps should be discussed and addressed for better evidence base and decision making. This commentary aims to provide a research insight into gaps and recommendations related to the analysis of economic cost of not meeting the 24-h movement guidelines. Some major research gaps can be indicated, including less research attention on excessive SB and inadequate sleep, limited evidence regarding NCDs associated with not meeting all 24-h movement guidelines considered in economic cost analysis, absence of evidence on estimated cost of not meeting the guidelines, and the adherence to methodological guide. Future research is required to address the gaps to guide effective health policy development in China. We hope that this commentary can play an important role in updating research evidence and advancing policy practice.
众所周知，不符合24小时(h)运动指南，包括身体活动不足（PA）、久坐行为过度（SB）、睡眠时间不足及其组合，是非传染性疾病（NCDs）的独立危险因素。在世界范围内，不符合指南的患病率很高，尤其是在人口最多的中国。一些研究估计了中国PA不足的经济成本，这有助于指导决策者制定和实施有效的卫生行动。然而，为了更好的证据基础和决策，应该讨论和解决一些研究空白。这篇评论的目的是对不符合24小时运动指南的经济成本分析的差距和建议提供研究见解。可以指出一些主要的研究空白，包括对过多的SB和睡眠不足的研究关注较少，在经济成本分析中考虑的与不符合所有24小时运动指南相关的非传染性疾病的证据有限，缺乏关于不符合指南的估计成本的证据，以及对方法指南的遵守。未来的研究需要解决这些差距，以指导中国有效的卫生政策制定。我们希望这篇评论能够在更新研究证据和推进政策实践方面发挥重要作用。

China has a high prevalence rate of Metabolic-associated fatty liver disease (MAFLD), and there is currently limited understanding of the levels of exercise self-efficacy (ESE) among individuals with MAFLD. The objective was to explore the potential ESE patterns in older adults with MAFLD. A cross-sectional study was conducted on 800 older adults with fatty liver disease from five communities from April 20, 2023 to August 15, 2023. Latent profile analysis (LPA) and k-means clustering were used to determine the optimal number of ESE groups. Using univariate analysis and multivariate logistic regression to investigate the factors influencing profiles of ESE. A sample of 775 subjects met the diagnostic criteria for MAFLD. LPA yielded three profiles: the low-ESE, mild-ESE, and high-ESE groups, which comprised 25%, 28%, and 47% of the sample, respectively. K-means clustering further supported the categorization of ESE into three distinct classes. The multivariate logistic regression analysis revealed that diabetes, arthritis and/or arthrosis, as well as companionship during PA were significant influencing factors for the different profiles (p ​< ​0.05). Our findings suggest that the ESE of older patients with MAFLD is primarily at a moderate level or above. There was population heterogeneity in ESE among older patients with MAFLD. Diabetes mellitus, arthritis, and/or arthrosis, as well as companionship during PA were significant factors in influencing the likelihood of having high ESE.
中国代谢性脂肪性肝病（MAFLD）的患病率很高，目前对MAFLD患者的运动自我效能（ESE）水平的了解有限。目的是探讨老年MAFLD患者的潜在ESE模式。本研究于2023年4月20日至2023年8月15日对来自5个社区的800名老年脂肪肝患者进行了横断面研究。使用潜在剖面分析（LPA）和k-means聚类来确定ESE组的最佳数量。采用单因素分析和多因素logistic回归分析探讨了影响ESE分布的因素。775名受试者符合MAFLD的诊断标准。LPA产生了三种概况：低ese，轻度ese和高ese组，分别占样本的25%，28%和47%。K-means聚类进一步支持将ESE分类为三个不同的类别。多因素logistic回归分析显示，糖尿病、关节炎和/或关节病以及PA期间的陪伴是不同情况的显著影响因素(p <；0.05)。我们的研究结果表明，老年mald患者的ESE主要处于中等或以上水平。老年MAFLD患者的ESE存在人群异质性。糖尿病、关节炎和/或关节病以及PA期间的陪伴是影响高ESE可能性的重要因素。

Marching band (MB) artists are often part of the general student population and not required to complete a pre-participation health screening to identify predisposing medical conditions or risks for injury/illness. Anecdotally, exertional heat illnesses (EHI) are a concern for MB artists. As more athletic trainers provide MB healthcare, research is needed on EHI occurrence and MB associated EHI risk factors. We utilized an exploratory cross-sectional study design to determine EHI risk factors, including previous EHI occurrence, among collegiate MB artists. MB artists (n ​= ​1 207; age ​= ​[19.6 ​± ​1.3] years) actively participating in their college/university's MB during the 2019 football season completed an online survey to characterize demographics, medical history, medication and supplement use, and nutrition behaviors. Chi-square and binomial logistical regressions assessed associations between categorical variables. Previous EHI was reported by 50.6% of MB artists, with 466 (76.3%) experiencing exertional heat exhaustion and 31 (5.1%) exertional heat stroke. More females reported exertional heat exhaustion overall (68.2%, p ​< ​0.001) and in the previous year (73.3%, p ​< ​0.001). Experiencing a previous EHI was significantly associated with having a mood/neurological condition (63.5%, p ​< ​0.001), diagnosed (74.3%, p ​= ​0.004) or perceived eating disorder (66.7%, p ​< ​0.001), and taking prescription medications (59.4%, p ​< ​0.001), over-the-counter medications (58.9%, p ​= ​0.002), and supplements (55.4%, p ​= ​0.037). Half of collegiate MB artists reported experiencing previous EHIs and engaged in behaviors known to increase EHI risk. MB artists should complete pre-participation examinations to identify pre-existing medical conditions and risks for adverse medical events. Healthcare providers working with MB artists should develop policies and procedures to mitigate EHI risks and occurrence.
游行乐队（MB）艺术家通常是一般学生群体的一部分，不需要完成参加前的健康检查，以确定易患的医疗状况或受伤/疾病的风险。有趣的是，劳累性热病（EHI）是MB艺术家所关心的问题。随着越来越多的运动教练提供MB保健，需要研究EHI的发生和与MB相关的EHI危险因素。我们采用探索性横断面研究设计来确定大学MB艺术家中EHI的危险因素，包括以前的EHI发生情况。MB艺人(n = 1 207；年龄=[19.6±1.3]岁)在2019年足球赛季期间积极参加其所在学院/大学的MB，完成了一项在线调查，以描述人口统计学，病史，药物和补充剂使用以及营养行为。卡方和二项逻辑回归评估了分类变量之间的关联。50.6%的MB艺人曾报告过EHI，其中466人（76.3%）经历过劳累性中暑，31人（5.1%）经历过劳累性中暑。总体而言，更多的女性报告了劳累性热衰竭（68.2%,pp p = 0.004）或饮食失调（66.7%,pp p = 0.002），以及补充剂（55.4%,p = 0.037）。一半的大学MB艺术家报告说，他们以前经历过EHI，并从事已知会增加EHI风险的行为。MB艺术家应完成参加前检查，以确定已有的医疗状况和不良医疗事件的风险。与MB艺术家合作的医疗保健提供者应制定政策和程序，以减轻EHI的风险和发生。

This study examined the repeated bout effect (RBE) on muscle damage markers following two bouts of neuromuscular electrical stimulation (NMES) in untrained individuals. Following familiarization, participants received 45 consecutive NMES to the biceps brachii at an intensity that produced low evoked force for the elbow flexors. Muscle damage markers (maximal voluntary isometric contraction [MVIC], elbow range of motion [ROM], muscle soreness via visual analogue scale [VAS] scores, pressure pain threshold [PPT], and muscle thickness) were measured before (PRE), after (POST), 1 day after (24 POST), and 2 days after (48 POST) NMES. Following 1 week of rest, procedures were replicated. Separate repeated measures two-way ANOVAs examined each measure. There were no interactions or bout main effects for MVIC or ROM. Time main effects indicated PRE MVIC was greater than POST (p ​= ​0.002) and 24-POST (p ​= ​0.024), and PRE ROM was greater than POST (p ​= ​0.036). There was no interaction for muscle thickness. Respective time and bout main effects indicated muscle thickness at PRE was less than POST (p ​= ​0.017), and second-bout muscle thickness (p ​= ​0.050) was less compared to the initial-bout. For PPT, there was an interaction (p ​= ​0.019). Initial-bout PRE PPT was less than POST (p ​= ​0.033). Initial-bout 48-POST PPT was less than second-bout 48-POST (p ​= ​0.037). There was a significant interaction for VAS (p ​= ​0.009). Initial-bout PRE VAS was less than POST (p ​= ​0.033) and 24-POST (p ​= ​0.015). Initial-bout POST and 24-POST VAS were greater than second-bout POST (p ​= ​0.023) and 24-POST (p ​= ​0.006), respectively. The results support RBE on muscle damage markers related to inflammation, but not MVIC and ROM.
本研究检测了未经训练的个体在两次神经肌肉电刺激（NMES）后肌肉损伤标志物的重复回合效应（RBE）。熟悉后，参与者接受45次连续的肱二头肌NMES，强度对肘关节屈肌产生低诱发力。肌肉损伤标志物（最大自主等距收缩[MVIC]，肘关节活动范围[ROM]，通过视觉模拟量表[VAS]评分的肌肉酸痛，压痛阈值[PPT]和肌肉厚度）在NMES之前（PRE），之后（POST）， 1天后（24 POST）和2天后（48 POST）进行测量。休息1周后，重复上述步骤。单独的重复测量，双向方差分析检查每个测量。MVIC和ROM的主效应没有相互作用，时间主效应显示PRE - MVIC大于POST （p = 0.002）和24-POST (p = 0.024)， PRE - ROM大于POST （p = 0.036）。肌肉厚度没有相互作用。分别在时间和回合的主要效应中，PRE的肌肉厚度小于POST (p = 0.017)，而第二回合的肌肉厚度小于初始回合（p = 0.050）。PPT存在交互作用（p = 0.019）。PRE -约比PPT小于POST （p = 0.033）。48-POST首回合的PPT小于48-POST第二回合（p = 0.037）。VAS有显著交互作用（p = 0.009）。初始回合PRE VAS低于POST （p = 0.033）和24-POST （p = 0.015）。第一次POST和24次POST VAS评分分别高于第二次POST （p = 0.023）和24次POST （p = 0.006）。结果支持RBE对与炎症相关的肌肉损伤标志物，但不支持MVIC和ROM。

This study aimed to determine the infection status, exercise habits, anxiety levels, and sleep quality in Chinese residents who recovered from infection during the period of coronavirus disease 2019 (COVID-19) period. It also aimed to investigate the influencing factors of recovery status and aid in improving intervention measures for COVID-19 recovery. This study is a sub-study nested within a cross-sectional investigation of infection and physical and mental health among partially recovered residents in all 34 provincial areas of China during the COVID-19 pandemic. A total of 1 013 participants (374 males and 639 females) completed the study. Cardiopulmonary endurance was significantly lower after infection than before infection (p ​< ​0.001). Women (3.92 ​± ​4.97) exhibited higher levels of anxiety than men (3.33 ​± ​4.54, p ​= ​0.015). The sleep score was significantly higher after infection (8.27 ​± ​7.05) than before infection (4.17 ​± ​4.97, p ​< ​0.001). The active and regular exercise groups exhibited significantly shorter durations of fever than the sedentary and irregular groups (p ​= ​0.033; p ​= ​0.021). Additionally, the active group demonstrated significantly fewer recovery days ([7.32 ​± ​3.24] days) than the sedentary group ([7.66 ​± ​3.06] days, p ​= ​0.035). We found a correlation between age and the recovery time of symptoms after COVID-19. We noted that a greater number of symptoms corresponded to poorer cardiopulmonary fitness and sleep quality. Individuals who engage in sedentary lifestyles and irregular exercise regimens generally require prolonged recovery periods. Therefore, incorporating moderate exercise, psychological support, sleep hygiene and other health interventions into post-COVID-19 recovery measures is imperative.

本研究旨在了解2019年冠状病毒病（COVID-19）期间中国居民的感染状况、运动习惯、焦虑水平和睡眠质量。该研究还旨在调查恢复状况的影响因素，并帮助改进 COVID-19 恢复期的干预措施。本研究是COVID-19流行期间中国全部34个省级地区部分康复居民感染和身心健康横断面调查嵌套的子研究。共有 1 013 名参与者（374 名男性和 639 名女性）完成了研究。感染后的心肺耐力明显低于感染前（p <0.001）。女性的焦虑水平（3.92 ± 4.97）高于男性（3.33 ± 4.54，p = 0.015）。感染后的睡眠评分（8.27 ± 7.05）明显高于感染前（4.17 ± 4.97，p = 0.001）。积极运动组和经常运动组的发热持续时间明显短于久坐组和不规律运动组（p = 0.033；p = 0.021）。此外，运动组的恢复天数（[7.32 ± 3.24] 天）明显少于久坐组（[7.66 ± 3.06] 天，p = 0.035）。我们发现年龄与 COVID-19 后症状的恢复时间之间存在相关性。我们注意到，症状越多，心肺功能和睡眠质量越差。久坐不动和运动不规律的人通常需要较长的恢复期。因此，将适度运动、心理支持、睡眠卫生和其他健康干预措施纳入 COVID-19 后的恢复措施势在必行。
